Roof frame with bay window. Features of the construction of the upper structure above the bay window. Hip hip roof

Centuries have passed, and in times of peace, the loopholes have changed - they have become floor-to-ceiling windows, and now play a decorative role, and also allow you to let more space into the house. sun rays, which is important in our not very friendly climate. The fashion for buildings with projections appeared in the last century, and this interesting architectural solution is still very popular in private construction.

To be fair, it is worth noting that the construction of such a structure is not a cheap pleasure. It's all about the complexity of designing and building the structure. What is a bay window? This is the part of the room that protrudes beyond the front wall, and is closest in structure to closed balcony with main walls, like the main building. You can acquire such a decoration and addition to your home not only during construction, but also by attaching a bay window to an already finished building - and it can be either single-story or multi-story. Complete with a glazed overhang, the house looks original from the outside. Interior design also does not disappoint: the room has an interesting layout, and the room will be brighter thanks to the panoramic windows. Due to the bay window, the usable area increases, which is used as an office, recreation area, greenhouse or dining room. The most difficult thing in constructing such an architectural form is the design and installation of the roof, which most often has a complex configuration.

Roof structure The most important rule: the roof of the bay window should be in harmony with the roof of the house, complementing general style. Its construction is a difficult task, and sometimes developers with considerable experience refuse to build a house with a bay window area in the plan. Any error in the calculations can lead to the entire structure becoming unreliable. The shape of the bay window can be: rounded; rectangular; multifaceted. The roof is built in accordance with the shape of the bay window. It can be multi-pincer, complex hip, have two or several slopes, and the upper structure is also made in the form of a hemisphere. You can often find decorations in the form of a turret, spire and other elements. Construction of the roof Rafters are selected with a smaller cross-section than for the main roof, since they will take on less load. There are two design options: independent roof bay window; combined with the main roof of the house. Reinforced belt The first stage in roof construction is the installation of a monolithic ring structure made of concrete with a metal mesh frame, which should encircle the walls - follow their contour. The reinforced belt serves as the basis for the rafter system - it creates support for the beams, and also relieves the window lintels, distributes the point load and strengthens the entire structure.

Rafter system The Mauerlat is attached along the perimeter of the armored belt. Roof trusses made of timber or boards mounted on the ground, lifted up and fixed to the ridge. The lower parts of the rafter legs must protrude beyond the wall to organize the eaves overhang. For reinforcement, completely traditional rafter beams, jibs, racks and other elements are used.

The proportions of the roof "skeleton" are extremely important to ensure an attractive appearance. Modern technology 3D modeling greatly facilitates the task of design specialists, allowing them to clearly verify that the slope angle is chosen correctly.

Training video on installing bay window rafters:

Lathing The rafters are covered with a waterproofing film, which is fastened without pulling too hard, after which the lathing is installed.

It can be continuous or sparse - depending on the type of roofing: the first option is suitable for soft coverings, the second - for metal tiles or any other hard material. The lumber from which the sheathing is made, as well as for the rafter system, is preferable coniferous species. Roofing The technology for covering a bay window roof is no different from the method of laying roofing material on a conventional upper structure of a house. The only thing that matters is whether the bay window roof will be a separate, independent element or integral part, a continuation of the roof of the main building. Most suitable coating By appearance tiles are considered - both natural and soft bitumen. In addition, for small area With multiple slopes and valleys, you need to choose a coating with little waste, and shingles meet these requirements.

To construct a roof of complex shape, many different fasteners are used - metal plates, studs, self-tapping screws, nails, and screws. Experts advise not to skimp on trifles: by choosing overheated cheap nails or screws, we risk the reliability of the entire structure. You can build a bay window roof with your own hands: you need to carefully prepare the project and think through the construction activities down to the smallest detail. Built independently or with the involvement of professional contractors, the resulting roof over the bay window long years will delight you with its original appearance and provide reliable protection for a bright and spacious interior.

Let's say you have already decided and chosen the style in which you will build your future home. Will it be permanent place residence or just a place where your family plans to come for the weekend - this does not affect the responsible attitude to construction.

In recent years, house designs with a bay window have become increasingly popular. Tired of cramped Khrushchev buildings with tiny windows, city residents are drawn to the sun and space. And what could be better for this than house designs with a bay window? Photos of projects demonstrated by development companies fully prove this.

So, what is a bay window? This is the protruding part of the house, usually in a semicircle or prism. Rarely - like a tower. As a rule, the bay window is built to the full height of the floor. It not only looks, but actually increases the area of ​​the house.

The main task of a bay window is that it allows as much light into the room as possible. But this is not the only plus. In the bay window you can arrange a flower corner or simply put a table and an armchair, where you can comfortably drink tea in the morning while admiring the sun and the view from the window. Particularly convenient in this regard are houses with two bay windows, projects of which are also available in the portfolio of development companies. There is plenty of room for your imagination to run wild: in one bay window there is a greenhouse, in the other there is a relaxation corner. Or give both bay windows for flowers - lovers of garden delights will like the idea. However, house designs with 2 bay windows will appeal to anyone who prefers comfort combined with beauty.

You can make an attic and a bay window on the same level - the second floor. Then the attic will be flooded with sun and become the most cozy corner in the house. Or you can separate both additions and install a bay window on the first floor. It is difficult to choose designs for two-story houses with a bay window or a project for a one-story house with a bay window, because there are many advantages and disadvantages in each option. But if you decide to country house with a bay window, choosing a project is a pleasure. Think this way and that, mentally or on paper sketch out options for the furnishings of the bay window and its shape, think about color scheme and designing a niche is a wild ride of imagination!

If you prefer small spaces and have chosen, for example, a 9 by 9 house project with a bay window, then this structure will add square meters and comfort to your home. However, if you are working on a 10 by 10 house project with a bay window, then the extra meters won’t hurt it either. Especially sunlit and decorated with flowers.

Perhaps this round or cylindrical extension is a very useful addition to the house. This is what makes cottage designs with a bay window so popular. The idea of ​​adding a bay window to a house is not the most ordinary, so most often those who want to add a bay window have to order an original design or develop it themselves. However, it is quite possible to find designs for houses with bay windows for free - there are quite a lot of them on the Internet. Bright, elegant, unique houses in photographs attract the eye and make you want to create the same miracle in your own home. Comfortable and cozy, such houses delight not only those living in them, but also guests, who then, perhaps, will also choose designs for houses and cottages with a bay window.

And, of course, these will be beautiful houses with a bay window, the projects of which any architect-designer will happily undertake to implement.

Often, projects of country houses with a bay window are chosen for consideration by those who dreamed of a castle in childhood, but to build a house in castle style doesn't want to. A bay window is a great opportunity to partially realize a dream without cluttering the façade and interior with excessive medieval gloom.

How to choose the right cottage designs with a bay window? Photo, perhaps the best option. It will help you visually and technically evaluate all the pros and cons of the chosen option. It’s not the easiest thing to choose designs for houses and cottages with a bay window, especially considering that the whole family will live in it, which means everyone should like it.

As for the glazing of the bay window, it can be different. If the bay window in your house is part of the house, then it is unwise to glass completely - heat is lost. But in summer house On the contrary, you can not spare the glass and the sun. Without glazing bay window summer house looks more like a veranda.

Some people may not like the idea of ​​a glass niche - well, tastes vary. Quite a lot of people wouldn’t even think twice about adding a bay window and the sun pouring through it into their interior. And someone will happily let the sun into the house by installing a window that spans the entire wall. By the way, an interesting solution would be to install a bay window in the attic. Imagine a house project with a bay window and an attic, photo, drawing. Introduced? Then it will be easy for you to understand what those who like such projects find in this style. Roofs of houses with a bay window look delightful and impressive, and add considerable benefits to the house. You can, for example, replace attic glass with a bay window - the effect is the same: the room is flooded with sun. And a bay window requires much less costs than a double-glazed window covering the entire wall or roof.

In addition to the sun, which will generously penetrate the room through the bay window, such an architectural solution has many other advantages. Like the attic, the bay window increases the area of ​​the house; the appearance of the building with a bay window is much

More spectacular, more refined than usual. It will be more beautiful than neighboring houses and will certainly attract the attention of passers-by and neighbors. Finally, it’s just convenient: if the glazing is not the entire wall, then under the window sill you can arrange hidden niches to store in them what is not required in this moment. If you have chosen a house project with a bay window and a garage, then it is more logical to arrange the garage just under the bay window. And then it will perfectly accommodate a greenhouse or a relaxation area: say, a sofa made in the shape of a niche, a table or a home cinema - it will be an excellent ensemble for relaxation. By placing a table and chairs “facing” the glass, you can drink tea while admiring the surroundings.

An important nuance when building a house is the material from which it will be built. A bay window can be added to any house, no matter what it is built from. Some will prefer house designs with brick bay windows, paying tribute to the quality and traditional nature of the material. Projects brick houses with a bay window are very popular precisely because of their traditional nature and excellent quality of the material.

But there are a lot of materials, and it is possible that someone will want to choose house designs with a bay window made of aerated concrete in order to be able to build a house on their own. And some will like the designs of houses made of foam blocks with a bay window.

When you decide to build a house with a bay window, you choose the project. The main thing is that the whole family likes living in such a house.

Almost every old house is decorated with an original projection. This protrusion is called a bay window. We see it in the photo. The main advantage of bay windows is their ability to pass a large number of sunlight. In addition, in this recess you can place a beautiful winter garden, create a study or create a relaxation area. Today, house designs with a bay window are also very popular. As a rule, a bay window structure is located in the living room or bedroom, which allows you to expand the space of the rooms and use the room more efficiently.

It is impossible to say that a project with a bay window has only positive or only negative qualities. These designs have both sides.

Positive properties

· Extension usable area in the house.

· Lots of sunlight thanks to multiple windows.

· Opportunity to enjoy an excellent view of city streets.

· Unique design that enhances the beauty of your home.

A house made of timber with a bay window looks unusually beautiful. In such a building, a special climate is preserved, which creates a homely, cozy atmosphere.

Negative qualities

· The complexity of the structure increases compared to a simpler project.

· The number of corners in the house increases, which leads to a weakening of the rigidity of the structure.

· A house with a bay window requires additional insulation.

If you want to have a home with a bay window design, you need to be prepared for the fact that it will take a little more effort than in a typical house.

Necessity

Perhaps, against the backdrop of all the pros and cons of such a building, the most important positive property one-story house with a bay window, is that in the cold northern parts globe, this design lets you skip maximum amount sunlight into the room, where you can place a bright and warm area for receiving guests. This option can serve as a replacement for the veranda. This is convenient, since in particularly cold countries, building a house with a veranda is an undesirable solution.

Variety of projects

"Double design"

The project of a two-story house with a bay window in the photo is suitable for those who cannot imagine their life without comfortable rest. The design of the building assumes the presence of a wide balcony along the façade on the second floor. There are two exits from the bedrooms to the balcony, one of which is equipped with a bay window. Moreover, the protruding structure does not end on the second floor, but smoothly transitions to the first floor. Thanks to the presence of a volumetric addition, the house looks solid and elegant.

The design of this building stands out against the background of other inexpensive buildings. The project involves an entrance hall, a kitchen, a living room-studio with a bay window and a spacious bedroom on the second floor. As a result, the two-story timber building has a total area of ​​36 sq.m., but thanks to the volumetric structure, the house looks original and cozy.

Building with bay window and attic

A small and financially profitable design is a house design that involves the presence of an attic room and a bay window. And although the construction of such a building requires certain financial investments, this combination occurs very often.

When creating a design for houses with a bay window, you must remember that this structure must be designed as accurately as possible. The slightest mistake can lead to distortion of walls and ceilings, which will lead to a decrease in the strength of the structure. You also need to know that it is absolutely not necessary to build a bay window at the same time as the house. The structure shown in the photo can be attached to the main building at any time.

Types of bay windows

In appearance, bay windows can be:

· Corner.

· Wall-mounted.

· Fit into a corner.

Most bay windows have a conventional geometric shape. However, this does not mean that the structure cannot have an arbitrary shape. Of course, the creation of atypical projects requires considerable financial costs from home owners.

To summarize, it should be noted that the bay window design literally enlivens a boring structure and allows you to reveal the beauty and uniqueness of the structure. Such extensions always create fabulous winter gardens, cozy areas recreation, in which home cinemas, cozy living rooms and comfortable children's corners are equipped. The bay window is a special highlight of the house, allowing you to add aristocracy and sophistication to any structure.

If a roof is being built over a bay window, then the first stage of work is the installation of an armored belt.

This structure performs two functions simultaneously:

· Creates support for the beams holding the rafters;

· Strengthens brickwork and relieves window lintels.

The armored belt is made of concrete with metal mesh reinforcement. If at the same time the level of the bay window walls turns out to be slightly higher than the level of the house walls, it’s okay. The fact is that in the bay window you can use rafter beams of less thickness than for the main roof, such as a standard hip roof.

Preparation of materials

In order for a bay window roof to be built, it is necessary to purchase following materials:

· Lumber for rafters, rafter beams and sheathing;

· Waterproofing material;

· Nails, self-tapping screws, studs, screws;

· Knitting wire;

· Galvanized plates.

Installation of rafter beams

The next stage of work, when the bay window roof is created, is the installation of rafter beams. For them, you can use timber of the required length or spliced ​​edged boards. Self-tapping screws are used to connect the boards.

Advice! It is advisable to make rafter beams of such length that there is a small margin left. Then, after installation and fastening, the excess can be trimmed along the cord.

Construction of the rafter system

To select the length of the rafters, you must accurately understand the angle of inclination created roof. Here it is important to maintain the proportions of the roof so that the house does not look like a birdhouse.

To visualize the view future roof, such as a hip roof, three-dimensional modeling is used in the design.

Installation of sheathing

Waterproofing is installed on the finished rafter system. The film should not be installed under tension so that it cannot burst due to temperature changes. Therefore, it is attached with some sagging.

Advice! When using modern waterproofing membranes It is convenient to use a construction stapler for fastening.

Then the sheathing is installed across the rafters. The pitch between the individual elements of the sheathing depends on the type of roofing material chosen. For example, when using metal tiles, the distance between the sheathing boards should correspond to the width of the tile element.

Laying roofing material during the construction of a bay window roof is carried out in the same way as when covering a conventional roof. But there is a difficulty in this work - the installation of valleys.

Typically, two types of gutters are required:

· PEN (lower valley strip) is a device used to drain rainwater, which will inevitably accumulate at the junction of the slopes

· PEV (respectively, the upper valley strip) is a decorative element for masking cuts on the roofing.

The valley strips are installed on a special board called the valley. The joints between gutters and roofing material should be treated with sealant. You can also use a universal seal.

The final part of the work

Laying the roofing material and installing the valley does not end with the solution to the question of how to properly install the roof over the bay window. The finishing part of the work is carried out indoors.

It is necessary to lay insulation and install a vapor barrier. After which you can move on to interior decoration- hemming the ceiling.

Of course, such architectural elements as bay windows greatly decorate the appearance of the house and allow you to plan original interiors.

In addition, the presence of a bay window in the house will make the rooms brighter and more comfortable. But the presence of this decorative element significantly complicates the installation of the roof, since it turns out to be multi-slope.

The intersection of the slopes forms internal corner, and this place on the roof is the most vulnerable, since rainwater accumulates there.

This internal angle at the junction of two inclined slopes in construction is called a valley. Let's look at how you can build a roof with such elements.

Preparation for construction

The first step in deciding how to install a roof of any shape is drawing up a project and choosing a team that will carry out the work.

It should be noted that installing a structure such as a multi-gable roof is a job that requires a high level of professionalism. Therefore, you should not try to do it yourself, and the choice of a team of repairmen should be treated with great attention.

Construction of the rafter system

Roof truss system

To select the length of the rafters, it is necessary to accurately understand the angle of inclination of the roof being created. Here it is important to maintain the proportions of the roof so that the house does not look like a birdhouse.

To visualize the appearance of a future roof, such as a hip roof, three-dimensional modeling is used during design.

The rafters should be prepared on the ground, after which they are lifted up and sewn together at the roof ridge using self-tapping screws and galvanized backing plates. Next, the two sides of the future “triangle” of the roof are attached to the rafter beams and jibs.

Installation of sheathing

Sheathing the roof before laying the roofing material

Waterproofing is installed on the finished rafter system. The film should not be installed under tension so that it cannot burst due to temperature changes. Therefore, it is attached with some sagging.

Advice! When using modern waterproofing membranes, it is convenient to use a construction stapler for fastening.

Then the sheathing is installed across the rafters. The pitch between the individual elements of the sheathing depends on the type of roofing material chosen. For example, when using metal tiles, the distance between the sheathing boards should correspond to the width of the tile element.

It is necessary to lay insulation and install a vapor barrier. After which you can move on to the interior finishing - lining the ceiling.

Yand roof: how to install a bay window correctly, proportions

How to make a roof with a bay window: types of forms, preparation, installation

Modern projects country houses and cottages include many different structural elements, which are necessary to solve certain functional problems. Often to clients construction companies They offer an option for a house with a bay window - this is a small space inside the building that extends beyond the plane of the building’s facade. From a technological point of view, a device of this type does not cause any problems, but special attention is always paid to the roof. In most cases, a yandow roof is installed over the bay window.

As a rule, a bay window is presented in country house construction in the form of a covered balcony. At the same time, its walls are an integral part of the floors of the house. The shape of the bay window structure also depends on the design solution, but most often it is multifaceted, semicircular, trapezoidal. In addition, the following types of roof shapes can be distinguished, which are usually installed in country houses above the bay window:

Preference is usually given to the hip version, since it is the easiest to perform from the point of view of professionals.

This design does not require serious financial and labor costs, and is also technologically advanced and reliably protects the interior from various negative influences.

Preparatory process

It is necessary to decide whether the hip roof will be above the bay window or some other one at the stage of designing a country house. This is due to the fact that the roof is almost always multi-sloped, so it will be necessary to make all kinds of ridges, gutters and other necessary structural elements to drain precipitation and debris. When creating a project, all possible types of roof are considered and the most optimal one is selected.

It’s worth noting right away that installing a yand roof is a rather complex and labor-intensive process, so the implementation of this task should be entirely on the shoulders of qualified specialists. Self-study similar works Not recommended. You will definitely need a high-quality rafter system, which is almost impossible to do with your own hands without the proper experience and skills.

At the initial stage preparatory work to install the roof above the bay window, it is necessary to make a reinforced belt. It is made from cement mortar and reinforcing bars or metal mesh. It is required to perform the following functions:

• The armored belt acts as a support for the beams supporting the rafter system. Without these beams, the rafter system cannot be constructed;
• A reinforced belt is also required to strengthen the brickwork and relieve the lintels of window structures;
• In addition, it is needed to strengthen the walls of the bay window, which is done by connecting them to the walls of the house.

When choosing a roofing material, you should consider your financial capabilities and personal preferences.

Experts note that for bay windows of country houses optimal solution is the choice of one of the modern types of tiles (bitumen, natural, metal tiles, etc.). This type of roof will harmonize well with the bay window structure.

Construction of the rafter system

A rafter system is a must for many types of roofs. Of course, a roof with a bay window should also have one. The construction of a rafter system for this type of roof can be made from wooden beams and boards. Their connection to each other, as well as to other structural elements, is carried out using screws, self-tapping screws and other suitable fasteners. The rafter system must consist of beams of sufficient size, and you need to choose with a margin, cutting off the excess length or width directly during installation. By and large, the principles of performing work on the construction of a rafter system in this case are not much different from traditional works when installing different types of roofs. The mauerlat is laid along the reinforced belt, while the rafter legs are attached to the mauerlat.

Installation of rafter legs is carried out at the initial stage. The rafter legs must be moved beyond the plane of the walls. This could then be used to form eaves overhangs. This will prevent moisture that flows down the roof from having a negative impact on the wall material. To secure various wooden roof elements, traditional self-tapping screws or special fasteners are usually used, which are resistant to corrosion and coated with a layer of galvanized steel.

The rafter system can be installed on the roof itself, regardless of whether it is hip or not.

In addition, it is possible that individual elements of the system will be assembled on the surface of the earth. This will depend on the design solution and project - whether the roof with a bay window will be an independent structure, or will become a continuation of the roof of the house. In those situations where the rafter system for a yand roof is assembled with separate trusses, then after they are raised onto the roof, they must be secured not only with a Mauerlat, but also to the ridge. Fastening to the ridge is usually done using steel plates. In this case, it is recommended to fasten the metal plates using a special rolling machine. If it is not possible to use it, then you can use a regular hammer.

Installation of sheathing

Before installing the sheathing, it is imperative to lay the waterproofing material, since the rafter system must be well protected from the negative effects of moisture. To prevent a break waterproofing film, you should not tighten it too much, and it is best to fasten it in a loose state.

To make sheathing for a roof with a bay window, a traditional edged board is usually used, which must be treated with an antiseptic compound before installation (it will protect the wood from insects). The sheathing is installed across the rafter system. But it must be taken into account that the use of certain roofing coverings will require a continuous sheathing device. If such a need arises, it is recommended not to use edged board, and OSB boards or plywood with increased moisture-resistant characteristics.

The main feature of a yand roof is the presence of valleys, which is why it is necessary to use metal aprons.

After installing the sheathing, the prepared roofing material is installed on it.

Roof with a bay window - its types, installation features

Roof with bay window: rafter system, photo diagram

Today, houses with a bay window are considered very fashionable, but when building them, difficulties arise in the process of decorating the roof over them. The roof structure must be in harmony with the design general structure and the design of the main roof, complementing and improving the style. Depending on the shape of the bay window, different types of roofs are used, but the hip roof is considered the most common.

Features of a hip roof

Hip roof with a bay window has a number of features that must be taken into account during its construction.

• The design has high strength characteristics, durability and an unusual appearance.
• During its construction, it is possible to arrange a residential attic room, since the process of creating roof windows is very simple.
• The hip roof has four slopes, sloping on all sides. Two of them are considered main, and two are lateral, located between the first two. Depending on the type of design, there may be more slopes.
• The classic hip roof model has two inclined pairs of sides, two of which are in the shape of a triangle, and two in the shape of a trapezoid. And the rafter structure has two peaks connected to each other by a ridge.
• The most labor-intensive and responsible process is the construction of a hip roof with a bay window. Allowing the slightest errors in calculations and drawing will lead to possible deformation of the roof structure.
• A hip roof with a bay window can be independent, or it can be combined with the roof frame of the entire building.

Important! The bay window rafters have a smaller cross-section than the main rafters of the main roof frame, due to the fact that these elements are subject to the least load.

Advantages and disadvantages

A hip roof with a bay window has the following advantages:

• The roof structure has an attractive and original design, which makes the structure unusual.
• The hip roof is resistant to wind loads due to the absence of gables. The smaller the angle of the slopes of the structure, the less the wind affects the rafter frame.
• The streamlined shape of all sides has good resistance to various precipitation.
• The process of insulating such a roof is simplified by the fact that the pie is located inside the structure.
• Depending on the height and slope of the sides of the roof, it is possible to use the interior to decorate a living room.
• The roof design can be with a large overhang, thereby providing additional protection for the walls of the house.
• Due to the absence of gables on a hip roof, the load on the foundation of the house is distributed evenly, and it also becomes significantly less.

• The disadvantage of such structures is the complexity of their construction. If even the slightest errors are allowed, the reliability of the design will be in question.
• The construction of such a roof is expensive.

Varieties

The hip roof is divided into several types, depending on the shape of its structure.

The diagonal ribs of the structure rest on the ridge run, and the overhangs are at the same height.

Does not have a ridge run. All the edges of the structure are brought together to one point. This type of roof is not suitable for decorating buildings with a bay window, since the shape of the house box should be square.

Distinguishes from classic look the presence of gables in which windows are installed for arranging a residential attic room. This type is divided into subtypes, and some of them can be used for arranging buildings with a bay window.

This type consists of a complex structure, since all sides have a different size, with divergence at different slopes. This look gives the house a spectacular and original look and is great for arranging bay windows. A roof with a bay window, the rafter system of which has a broken frame, allows you to maintain maximum free space, for decoration of the attic space.

Roof drawing and calculation of its area

Before erecting a roof with a bay window, it is necessary to draw up a project that includes preparing a diagram of the future structure, as well as calculating the necessary building materials. Calculation and drawing up of the diagram is carried out in the following sequence:

Selecting the angle of the sides

The choice of the angle of inclination of roof slopes is made taking into account the following criteria:

• In what climatic conditions is the building located, as well as the wind load. With a heavy load, the roof slope should be as flat as possible. The lower the slope, the stronger the structure.
• If there is a large amount of precipitation, the roof slope should, on the contrary, be as high as possible so that it rolls off in a timely manner without thereby affecting the roof surface.
• A variety of roofing material, since each type has its own requirements for the sheathing, and also has different weights. For each type there are some restrictions on the slope of the slope:

Important! The higher the angle of inclination, the larger area roofs, which entails the purchase of additional building materials. This nuance must be taken into account when drawing up a drawing.

Drafting

Having taken into account all the features, you can proceed to designing the roof structure with drawing up a drawing and calculation of building materials. To do this you need:

• Measure the parameters of the house and the ledge: height, width and length.
• Schematically display the facade and end of the building on paper, using a certain scale.
• Depending on the characteristics of the house, choose the type of hip roof.
• Having decided on the height of the roof, according to the above criteria, draw several models of the roof frame on one of the sketches. Choosing the most suitable option, it is necessary to indicate the angle of inclination of the sides of the structure. To do this you need to use a protractor.
• Next, the location of the rafters is plotted on the drawing, marking them with dots. To do this, the length of the wall is divided into equal sections, which will be the step between the slings.
• The pitch between the slings also depends on the section and characteristics of the wood used.
• The need for thermal insulation of the roof. In this case, the location of the rafters must correspond to the width of the insulation.
• The drawing should also indicate the bay window rafters.
• If the type of roof provides ridge run, it is necessary to take into account that it must connect a pair of beams of the rafter system. On one of the drawings you need to mark equal sections from each edge of the wall.
• From the received sketches, one is compiled large drawing, which will also be useful in the future for calculating materials.

Important! Having a project and a schematic representation of the design is a good help when purchasing materials, manufacturing workpieces and in the process installation work.

How is area calculated?

Calculation of building materials is carried out according to certain formulas, taking into account the slope of the roof and the area of ​​the roofing surface.

For the calculation you will also need the following data:

• The presence of chimney pipes and dormer windows in the roof. Their presence increases the consumption of building materials.
• The length of the slope, its calculation is made from the ridge to the edge of the cornice.
• The parameters of the firewall walls, overhangs, parapets, and other parts are calculated.

To obtain accurate data when calculating, it is recommended to seek help from professionals or use a special program on the Internet. When deciding to perform the calculation yourself, it is recommended to divide the roof surface into separate sections, which will make it easy to calculate their area. After which all values ​​are summed up.

The more accurately the roofing surface area is calculated, the lower the cost of purchasing excess building materials will be.

Advice! To obtain a reliable and durable roofing structure, it is necessary to purchase well-dried timber for its construction.

Construction tools

The preparation of materials and tools is carried out before the installation process, so as not to be distracted by searching for them during the work process.

To simplify the measurements and for their accuracy, it is recommended to replace the tape measure with a measuring rod, which can be made of plywood, 5 cm wide, applying the main measurements to it.

Features of the installation process

Any construction process has its own characteristics, and the construction of a hip roof with a bay window is no exception.

• Before starting installation of the frame, it is recommended to treat all lumber with an antiseptic.
• To make and secure the rafter frame, it is necessary to prepare a mauerlat, which is laid on top of the walls, along the entire perimeter of the building. It performs the function of tying the rafter system to the walls of the building.
• Since intermediate rafter beams have a steep slope, unlike slanted rafters, boards with parameters of at least 5 * 15 cm are used for their manufacture.
• During construction rafter frame, first, vertical posts are installed that support the ridge girder. The racks are fixed to the central beam using a bevel system.
• The fastening of short rafters is carried out not to the ridge beam, but to the sloping elements of the frame. The slope angles of intermediate and short rafters must match.
• The bay window rafter system, photos of the diagrams of which are presented above, must be in harmony with general design, but may have a smaller cross-section of beams, since the imposed load from external climatic factors is much lower.
• The beams used for the construction of the rafter system and the ridge run must have the same cross-section. If this requirement is met, the structure will be strong and its rapid deformation will not occur.
• The intermediate rafters are attached to the ridge purlin and the upper part of the trim.
• When constructing a roof of small height, it is necessary to install additional support posts.
• To obtain a durable roofing structure, it is recommended to use softwood lumber, free from defects and knots.
• For high wind loads, the diagonal and central beams must be thick.
• After the frame is erected, it is hydro- and thermally insulated using a pre-fabricated sheathing.

To summarize, we can say that to equip a building with a bay window, a hip roof is often used, which has several varieties and, depending on the shape of the protrusion, the most suitable type is selected.

Before constructing a rafter system, it is necessary to draw up a project, which includes drawing up a drawing and performing calculations of building materials. To obtain durable and durable design It is better to entrust the creation of a project to professionals.

How the hip roof rafter system works + step-by-step installation instructions

A hip (hipped, hipped) roof is one of the design options when additional slopes are built in place of the gables.

Nevertheless, hip designs are widespread, especially in areas with frequent changes in wind direction.

The result is a roof with inclined planes on all sides, which creates a lot of advantageous positions:

• The absence of gables makes the load on the foundation less, and it is distributed absolutely evenly.
• The wind load on the slope is much lower than on the vertical plane.
• The costs of finishing the gables are excluded from the total repair estimate.
• Decoratively, the hip roof looks more solid and assembled.

The disadvantage of this design is:

• Increased complexity of the rafter system design.
• Greater consumption of roofing material, which creates additional dangerous areas of possible leaks.
• The presence of bursting loads on load-bearing walls, necessitating the need to tie down the lower bases of the slopes.

Hip roof: rafter system

The main design feature of a tent-type rafter system is the presence of diagonal edges, connecting corner points roofs with a ridge beam, which is shorter than the entire roof (the classic hip roof does not have a ridge at all, the ribs converge at one point).

In the rafter system, these ribs are called corner or diagonal. Their presence requires installation as full rafters, going from the ridge to the base - the Mauerlat, and shortened elements- frames connecting the base and diagonal rafters.

Hip roof scheme

Hip roof: elements of the rafter system

The elements of a hip-type rafter system have a more numerous composition than with gable design. Four rafter system pitched roof consists of the following parts:

• Mauerlat. Beam laid around the perimeter load-bearing walls and being the basis for the entire rafter system.
• Sill. A horizontal beam of the same cross-section as the Mauerlat, located along the longitudinal axis of the roof and serving as a support for the purlin posts. A layer of waterproofing is required between the ceiling and the floor.
• Sprengel. Element that binds and strengthens corner connections Mauerlat bars. It is made from the same timber as the Mauerlat and is installed diagonally to it.
• Puff. Connecting elements connecting the parallel bars of the mauerlat along the long side. Remove the bursting load from load-bearing walls.
• Rack. A vertical element supported by a tie and supporting a ridge beam.
• Run. Ridge beam.
• Diagonal (corner, slant) rafters. Connects the corners of the Mauerlat with the ends of the purlin, forming ribs - the junction of the roof planes.
• Rafters. Inclined elements resting on the mauerlat from below and on the purlin from above.
• Narozhniki. These are the elements that rest on top of the diagonal ribs. Essentially these are rafters cut to the length required at a given point.
• Struts. Reinforcing elements, spacers located perpendicular to the rafters and resting at an angle on the tie rods.

The designs of all elements may have deviations from the generally accepted design due to the necessity caused by the design features of a given building, but the scheme as a whole almost always consists of the named parts and does not have any radical changes.

Hip roof rafter system: diagram and photo below.

Rafter system diagram

Photo of the rafter system

Diagonal rafter legs

The elements of the rafter system that form the ribs connecting the planes of the slopes are called diagonal (oblique, corner) rafter legs.

Strictly speaking, diagonal and oblique - not entirely identical elements, since the former are attached to the outside of the corners of the Mauerlat, and the latter - from the inside.

Otherwise, all properties are the same.

Corner elements have certain features:

• The length of the diagonal rafter legs significantly exceeds the length of the straight rafters.
• Diagonal rafter legs serve as support for the frames on both sides of the connecting planes.

The presence of such features creates an increased - approximately one and a half times - load on slanted rafters compared to conventional ones. Their length exceeds the usual length of the boards, from which the rafters are made, therefore, to make the slope boards, they are welded together - they are connected along the plane in two layers.

This solves several problems at once:

• You can make beams of any desired length.
• Possibility to use one modular size material.

One or two supports must be installed under the diagonal rafter(depending on the length), and the point of support is not in the middle, as it would seem at first glance, but at a distance of one third to a quarter of the entire length of the slanted rafter, counting from the top point, since it is in this area that the place of greatest stress is located.

Diagonal rafter legs

Supports for diagonal rafters

Either struts or vertical posts made of timber or paired boards can be used as support for diagonal rafters. The stand can rest directly on the ceiling, through a layer of waterproofing and a wooden lining.

The angle of inclination of the strut does not play a role in this case., the main thing is the connection point, i.e. Load concentration location. For a rafter length of up to 7.5 m, a brace from the top point is sufficient maximum load, and with a length of more than 9 m, an additional stand is required at the bottom.

This can be either support on the ceiling, if it allows, or support on the truss - the so-called. truss truss - a stand reinforced with struts on the sides.

Supports for diagonal rafters

The device of the narozhniki

In the lower part there are rafters - the same rafters, have a completely similar method of attachment to the Mauerlat, same installation step. Mounted strictly at right angles to the base, the upper part - to the corner rafter leg.

Fastening is carried out with at least two nails or other elements. Top part the frame is cut at the desired angle to the horizon and to the diagonal rafters, to ensure a tighter connection and guarantee resistance to loads.

Hip roof over bay window

A bay window is a solid-looking structure that decorates a building, which is a small extension, a protrusion in the wall, performing mainly decorative functions. The section of the roof above the bay window can be of any type of structure, but most often the option that is most suitable for the shape and cross-section of the bay window is used.

The hip roof above the bay window may have an adjacent form, i.e. be half of a hip roof, a complex of three planes. Alternatively, there may be a dominant dome over the bay window, rising above the main roof.

Anyway, constructing such a structure is a difficult task, and the complexity is not in the technical sense, but in design and calculation work. The combination of several planes into one ensemble is a complex problem that requires precise calculations and careful, thoughtful work.

There are important points that play a significant role - for example, the angle of inclination of the bay window slopes must correspond to the angle of inclination of the main roof, the length of the fillies must also be in harmony with all the roof overhangs.

The main feature is the combination of hip elements with valley ones, therefore the construction of the main rafter system should be carried out parallel to or up to the bay window to avoid unwanted discrepancies in the system geometry.

Step-by-step instructions for installing a hip rafter system

The description will begin from the moment the mauerlat is laid, all previous operations are considered completed, the ceiling is completely ready.

All calculation and design work has also been completed.

There is prepared (dried) material - timber and edged boards made of coniferous trees, which are most suitable for the construction of a rafter system in all respects.

For correct installation elements of the rafter system must be stocked connecting elements , allowing some movement of parts relative to each other.

This is necessary to compensate for the shrinkage processes of the walls, foundation and the system itself. This is especially important for some load-bearing elements resting on the Mauerlat.

Movements of the base with fixed connections of the main components can lead to weakening of the connections and the formation of leaks.

Let's consider the stages of constructing a hip rafter system:

1. Mauerlat installation. The timber is laid on a waterproofed base and secured with studs. If necessary, the segments are connected along the length of the “half-tree”, with the connections reinforced with nails. The fasteners are installed immediately.
2. The corners of the Mauerlat are reinforced with trusses And.
3. Installation of the bed. One or two (depending on the project) planks are laid on a waterproofed base.
4. Racks are being installed, on which the purlin is attached. In this way, the supporting skeleton of the rafter system is created.
5. Diagonal rafter legs are being installed. Immediately, depending on the length, struts and (or) racks are installed.
6. Rafters are installed according to design data. The length/angle is immediately adjusted and the spigots are installed. All elements are, if necessary, reinforced with struts.
7. The rafters at the points of attachment to the base and to the purlin are additionally reinforced with brackets, wooden blocks and other fasteners.

Actually, the installation of the rafter system is completed at this stage. Further work consists of creating roofing pie, construction of sheathing, roofing, etc.

It is necessary to take into account the impossibility of complete and detailed coverage of all the nuances and details, on which the high-quality and reliable construction of the rafter system depends, since there are many of them and they are all worthy of separate consideration. Nevertheless, the general sequence is reflected in sufficient detail.

Creating a hip rafter system is not so much a complex process as it is responsible and dangerous because mistakes made in the early stages become noticeable much later.

That's why it is very important to draw up before starting work detailed plan works, ensure full compliance with the project and do everything as carefully as possible. The entire structure is supported by connections wooden parts Therefore, it is advisable to have experience and skills in working with wood.

Without possessing this knowledge, it is better to seek help from specialists, since the responsibility of the rafter system for preserving the functional qualities of the entire building is too great.

A bay window is a part of the room that extends beyond the plane of the facade. The fashion for such architectural solutions has not disappeared since the Middle Ages. Making a bay window on the roof is not easy even for experienced builder. The main secret of construction is experience and knowledge about the features and types of construction, methods of its construction.

Advantages and disadvantages of a roof with a bay window

Externally, the bay window looks like a terrace or balcony. But structurally it is part of a house with main walls. Depending on the project, it can occupy several floors, have a semicircle, trapezoid, rectangle or other polyhedron at its base.

Bay window roofs have many advantages:

• aesthetically attractive appearance;
• good resistance to strong gusts of wind - ensured by the absence of a roof gable;
• streamlined shape, making the roof structure above the bay window reliably protected from various types precipitation;
• simplified insulation process;
• the ability to use the under-roof space as a living space or for domestic needs;
• the opportunity to apply unusual design solutions when arranging the under-roof space;
• a large amount of natural light in the rooms;
• additional protection of load-bearing walls above the bay window due to the large overhang of the roof;
• reducing the load on the foundation and its more even distribution due to the absence of a roof gable.

The bay window roof structure has many advantages, but there are also a number of disadvantages:

• complexity of installation work - mistakes made are difficult to correct, and they significantly reduce reliability architectural element and neutralize its advantages;
• the construction of a bay window roof requires large financial investments - the design and construction work is quite complex and expensive;
• increase in heat loss.

Varieties and types of bay window designs

Bay window structures can vary in size and shape. They can also vary in area:

The height of a bay window can be designed as follows:

Designers and builders can give the bay window almost any shape. The most common include:

1. Trapezoid. The sides are adjacent to the facade at various angles, with the exception of the straight one. The central window, as a rule, is larger than those located on the sides.
   
   
2. Semicircle, or Venetian type of bay window. Gives the appearance of the house smooth lines. Looks good both from the street and from the inside. This type includes turrets located at the corners of buildings.
   
   
3. Rectangle. It is formed when the sides adjoin the facade at right angles. The interior has the usual parameters, but does not look so interesting.
   
   
4. Triangle. Not as common as previous types of construction. However, it looks original.
   
   

There are also more complex geometric shapes. They determine not only the appearance of the building, but also the interior of the premises.

Rafter system of a house roof with a bay window

The structure of the bay window rafter system consists of ridge beam, as well as rafters for various purposes. Since roof slopes may have unequal angles of inclination, there are several types of rafters, the main of which are:

• central intermediate– they are attached to each end of the ridge beam, three pieces;
• corner, or slanting, rafters– serve as the main load-bearing parts of the structure, are located in the corners of the frame, have the smallest slope in comparison with intermediate rafters;
• intermediate - located from the trim to the ridge, between the central rafters.

When installing the roof truss system, the following is also installed:

• ridge purlins - crossbars, directed horizontally and creating support for the central and corner rafters;
• outer, or short, rafters a – parts of the structure that are attached to the corner rafters and trim and have the same slope;
• Mauerlat - a beam attached to the top of the external walls and evenly distributing the load of the rafters, serving as the base, the connecting link of the roof frame and walls;
• strut - a support for rafter legs of large spans, allows you to overlap large spans and save sections of the main beams.

How to calculate the area of ​​a bay window

To measure the bay window area, the following tools are used:

• a ruler is the least accurate measuring device, giving large errors;
• tape measure – suitable for measuring small areas;
• A laser range finder is a tool that shows the most accurate measurement result and makes it possible to carry out work without the help of a partner.

The main problem when calculating the area of ​​a bay window is its complex shape, beveled or rounded. If it is not a rectangle or triangle, but a more complex polygon, it should be divided into several simple shapes.

The next steps are:

1. Measure all sides.
2. Draw a drawing and mark the data obtained on it.
3. Using formulas for calculating areas, make calculations for simple figures.

How to make a bay window with your own hands

The initial stage of building a bay window is drawing up a project, planning the shape. In some cases, additional documents have to be completed. If the construction of the structure goes in parallel with the construction of the house, then there is no need for them. If a bay window is being added to a building that has been in use for some time, it is necessary to make amendments to the project and obtain permission for the extension.

Laying the foundation

The structure of the foundation for a bay window structure is similar to the foundation of a building. Monolithic tape is suitable. Stages of its construction:

• digging a trench;
  
  
• creation of formwork;
  
  
• insulation;
  
  
• reinforcement;
  
  
• pouring concrete.
  
  

The foundation needs shrinkage, after which it is treated with waterproofing materials.

Construction of a bay window

If you build a bay window with your own hands, then without appropriate experience it is not recommended to build it above one floor. Most suitable materials– brick or aerated concrete. Masonry has a number of features that are important to consider:

1. Can be used for interior walls gas silicate blocks or aerated concrete.
2. For external masonry, it is better to take high-quality facing bricks.
3. When using both brick and aerated concrete, it is necessary to correctly calculate the load on the foundation.
4. Thermal insulation should be in the middle layer. It could be mineral wool or more modern sprayed materials.
5. It is important to provide waterproofing - membrane film or similar solutions.
6. The bay window and walls of the building must be a monolithic structure. This allows you to avoid operational problems.

Roof over bay window

The main rule when constructing it is that the roof must fit harmoniously into the overall style of the roof.

In practice, there are several types of roofs over a bay window:

The simplest option for a roof over a bay window is a continuation of the roof of the main building. Its shape depends on the shape of the bay window (semicircular, trapezoidal, rectangular, triangular).

Types of roofs above a bay window

The following common types of roofs over bay windows are distinguished:

1. Hip - performed in oblong-shaped buildings, has a ridge and four slopes, two of which are triangles in shape, two are trapezoids.
   
   
2. Tent - used for small-area bay windows, it gives the building a similarity to a tower, and has a large number of edges.
   
   
3. Multi-pincer – extremely complex design bay window roofs with gables and valleys, a type of pitched roof with two or more gables, gable elements with skates.
   
   
4. Decorative - equipped with additional structures, for example, turrets.
   
   

The main criterion when choosing the type of roof over a bay window is whether it performs its functions. The most common is the hip roof of a one-story house with a bay window, which is the simplest in design. It does not require significant labor and material costs.

• roof height;
• the angle of inclination of each slope;
• ridge girder size;
• span width;
• ways to strengthen the structure;
• features of fastening structural elements.

How to properly make a roof on a bay window with your own hands

When installing the bay window and roof rafter system, as a rule, the same materials are used as for the main roof:

• soft roof;
  
  
• metal tiles;
  
  
• corrugated sheeting;
  
  
• slate.
  
  

In addition, the following materials are needed for construction:

• screws, self-tapping screws and nails;
• rafter beams;
• galvanized iron:
• beams for sheathing.

Stages of work:

1. The initial stage of work is the preparation of the reinforcing belt. This is a support for beams, which also makes the masonry more durable. The belt material is concrete and reinforced mesh.
   
   
2. Next, they begin to install the rafter beams. They use boards and timber, connected with self-tapping screws. They are cut with small gaps, which are removed after the beams are secured.
   
   
3. Before proceeding with the installation of rafters, check the angle of the roof. The rafters are adjusted on the ground, after lifting, they are sewn together at the ridge of the roof using metal plates and screws, and attached to the rafter beams.
   
   
4. Then the rafter system is covered with waterproofing material and a sheathing is constructed.
   
   
5. They proceed to the most difficult stage of installation, installing valleys using various gutters. The lower strips are necessary for draining water and snow. The top bar performs a decorative function and hides imperfections. They are attached to the valley board, and the joints are treated with sealant.
   
   
6. At the final stage, the roof above the bay window is insulated and hemmed.
   
   

Experienced builders advise paying attention to the following points:

1. Before you finally choose the size and type of roof over the bay window, it is worth making a scaled-down three-dimensional model.
2. Any lumber used in roof construction must be treated with antiseptics.
3. Foam for waterproofing must have at least two layers so that insulation can be placed close to it.
4. The waterproofing film must be highly permeable to water vapor.
5. Valleys must be galvanized, since the requirements for their moisture resistance and corrosion resistance are the highest.

Conclusion

Construction of a bay window and a beautiful, reliable roof with skillful hands he gives the entire building a respectable appearance. Making a bay window on the roof means increasing the internal area and transforming the premises into brighter and more spacious ones. Bay window structures create wonderful recreation areas, winter gardens, and comfortable children's rooms.

Modern designs of country houses and cottages include many different structural elements that are necessary to solve certain functional problems. Construction companies often offer clients the option of a house with a bay window - this is a small space inside the building that extends beyond the plane of the building’s facade. From a technological point of view, a device of this type does not cause any problems, but special attention is always paid to the roof. In most cases, a yandow roof is installed over the bay window.

As a rule, a bay window is presented in country house construction in the form of a covered balcony. At the same time, its walls are an integral part of the floors of the house. The shape of the bay window structure also depends on the design solution, but most often it is multifaceted, semicircular, trapezoidal. In addition, we can distinguish the following types of roof shapes, which are usually installed in country houses above the bay window:

• hip;
• multi-pincer;
• decorative;
• in the form of a hemisphere.

Preference is usually given to the hip version, since it is the easiest to perform from the point of view of professionals.

This design does not require serious financial and labor costs, and is also technologically advanced and reliably protects the interior from various negative influences.

Preparatory process

It is necessary to decide whether the hip roof will be above the bay window or some other one at the stage of designing a country house. This is due to the fact that the roof is almost always multi-sloped, so it will be necessary to make all kinds of ridges, gutters and other necessary structural elements to drain precipitation and debris. When creating a project, all possible types of roof are considered and the most optimal one is selected.

It’s worth noting right away that installing a yand roof is a rather complex and labor-intensive process, so the implementation of this task should be entirely on the shoulders of qualified specialists. It is not recommended to carry out such work on your own. You will definitely need a high-quality rafter system, which is almost impossible to do with your own hands without the proper experience and skills.

At the initial stage of preparatory work on installing a roof over the bay window, it is necessary to make a reinforced belt. It is made from cement mortar and reinforcing bars or metal mesh. It is required to perform the following functions:

• The armored belt acts as a support for the beams supporting the rafter system. Without these beams, the rafter system cannot be constructed;
• A reinforced belt is also required to strengthen the brickwork and relieve the lintels of window structures;
• In addition, it is needed to strengthen the walls of the bay window, which is done by connecting them to the walls of the house.

When choosing a roofing material, you should consider your financial capabilities and personal preferences.

Experts note that for bay windows of country houses, the optimal solution is to choose one of the modern types of tiles (bitumen, natural, metal tiles, etc.). This type of roof will harmonize well with the bay window structure.

Construction of the rafter system

A rafter system is a must for many types of roofs. Of course, a roof with a bay window should also have one. The construction of a rafter system for this type of roof can be made from wooden beams and boards. Their connection to each other, as well as to other structural elements, is carried out using screws, self-tapping screws and other suitable fasteners. The rafter system must consist of beams of sufficient size, and you need to choose with a margin, cutting off the excess length or width directly during installation. By and large, the principles of performing work on the construction of a rafter system in this case are not much different from traditional work when installing different types of roofs. The mauerlat is laid along the reinforced belt, while the rafter legs are attached to the mauerlat.

Installation of rafter legs is carried out at the initial stage. The rafter legs must be moved beyond the plane of the walls. This could then be used to form eaves overhangs. This will prevent moisture that flows down the roof from having a negative impact on the wall material. To secure various wooden roof elements, traditional self-tapping screws or special fasteners are usually used, which are resistant to corrosion and coated with a layer of galvanized steel.

The rafter system can be installed on the roof itself, regardless of whether it is hip or not.

In addition, it is possible that individual elements of the system will be assembled on the surface of the earth. This will depend on the design solution and project - whether the roof with a bay window will be an independent structure, or will become a continuation of the roof of the house. In those situations where the rafter system for a yand roof is assembled with separate trusses, then after they are raised onto the roof, they must be secured not only with a Mauerlat, but also to the ridge. Fastening to the ridge is usually done using steel plates. In this case, it is recommended to fasten the metal plates using a special rolling machine. If it is not possible to use it, then you can use a regular hammer.

Installation of sheathing

Before installing the sheathing, it is imperative to lay the waterproofing material, since the rafter system must be well protected from the negative effects of moisture. To prevent the waterproofing film from breaking, do not tighten it too much, and it is best to fasten it in a loose state.

To make sheathing for a roof with a bay window, a traditional edged board is usually used, which must be treated with an antiseptic compound before installation (it will protect the wood from insects). The sheathing is installed across the rafter system. We take into account that the use of certain roofing coverings will require the installation of continuous sheathing. If such a need arises, it is recommended to use not an edged board, but OSB boards or plywood with increased moisture-resistant characteristics.

The main feature of a yand roof is the presence of valleys, which is why it is necessary to use metal aprons.

After installing the sheathing, the prepared roofing material is installed on it.

When building a private house, you need to pay special attention to the development of the project, in particular the roof of the building. At the moment, country houses and cottages welcome the presence of various structural elements and details that can make the house more attractive. In addition, they are designed to solve some functional problems.

Leading experts recommend using an element such as a bay window when building a private house. A bay window is a small space in a building that extends beyond the plane of the building’s facade. If we touch on the technological side of the issue, then there are no special problems here, but it is necessary to pay special attention to the roof of the bay window. Often a yandow roof is installed above the bay window.

In most cases, a bay window is a small covered balcony in a private house. At the same time, the walls of the bay window are part of the ceiling of the building. The shape of the bay window directly depends on the project, the designer’s ideas and the wishes of the customer. However, in most cases, the bay window is made multifaceted, semicircular or trapezoidal, since these shapes are the most successful and attractive in appearance.

In most cases, the following types of roofs are used for bay windows:

• Multi-pincer.
• Hip. This option is the most convenient and practical, as it is affordable and one of the easiest to implement.
• Hemispherical or decorative roof.

In general, the bay window protrudes original design building that can transform it and make the appearance of the house more attractive. To implement a bay window, no capital labor or financial costs are required. In addition, this element is considered technologically advanced and reliable, as it is able to protect the facade of the building and interior space from negative factors and environmental influences.

Preparatory work

First of all, you need to decide on the type of roof that will be used above the bay window; the customer must do this during the design of the building. This importance of the type of roof is determined by the fact that the roof of the bay window will be multi-sloped, which means that the construction of ridges, gutters and other structural elements is required to help melt water, snow masses and leaves not linger on the surface of the roofing material. During project development, all options are analyzed, after which the optimal one is selected in a particular case.
Creating a yand roof is a difficult and energy-consuming process, so it should be entrusted to professionals; trying to build the structure yourself is not recommended. To create a high-quality rafter system, you need a lot of experience and special skills; an ordinary person does not have them. Independent development of a yand roof can lead to failure and be fatal, so experiments here would not be appropriate.

During the preparatory work to create a roof above the bay window, you need to create a reinforced belt, which will require cement mortar and reinforced rods or metal mesh.

The reinforced belt performs the following functions:

• Serves as a support for the beams supporting the rafters. Creating a rafter system without beams is impossible.
• With its help, they strengthen the brickwork and relieve the lintels of window structures.
• Strengthens the walls of the bay window, as it directly communicates with them.

When choosing roofing material, the homeowner can only be limited by his own imagination and financial resources. In general, architects and designers advise using modern tiles for the bay window roof. It is intended to use both soft or natural and metal tiles. This choice is explained very simply, because a roof with such a coating will always look attractive and will be able to harmonize with the design of the bay window and the surrounding landscape design.

Rafter system

The rafter system is an integral part of almost any roof, especially if a complex type of roof is used. The roof over the bay window is no exception. To create a rafter system, boards and wooden beams, which are specially connected to each other using screws or self-tapping screws. To create a rafter system, it is necessary to select high-quality wood and beams of the required size; this must be done in such a way that there is a small margin that can be trimmed during the construction of the roof.

In general, the creation of a rafter system is standard and is no different from what is carried out for regular roofs. Mauerlat must be laid around the perimeter reinforced belt, the rafter legs must be attached to the mauerlat. Rafter installations are carried out on initial stages, this must be done in such a way that the edges of the rafters extend beyond the plane of the walls. This procedure is carried out so that the rafter legs hang down a little, due to which the eaves overhangs are then formed. They are installed to prevent water from flowing under the roof and protect the façade of the house from snow, rain and dirt.
For fastening wooden elements Roof structures use self-tapping screws or special fastening systems that are resistant to corrosion due to galvanized steel coating. The rafter system can be installed on the roof surface, regardless of what type it is.

It is also possible that some elements of the rafter system will be assembled on the ground and then raised to the roof level using special equipment. In this case, everything depends on the design solution and the developed project - a bay window with a roof can act as an independent structure or be an extension of the roof of the house.
In the case when the yand roof truss system is developed using separate trusses, it must be lifted onto the roof and then secured. Fastening work is carried out with both the Mauerlat and the ridge. The roof must be secured to the ridge using small steel plates. To fasten the plates, a special rolling machine is used; if it is not available, a classic hammer will do.
