One-story house with a flat roof of a wooden house. Experience in operating a country house with a flat roof in Russia. Types of flat roofing

Non-professionals associate a flat roof with the negative legacy of the Soviet past, when administrative buildings this type had an unprepossessing, gloomy appearance, and upper floors high-rise buildings suffered from constant leaks. Over the past 10-15 years, production roofing materials has undergone significant changes, thanks to which it was possible to create durable, strong and reliable polymer coatings new generation. From that moment on, flat roof house designs began to gain popularity.

Single storey – traditional architectural form southern coastal towns, resorts and luxury villas in Art Nouveau style, where a mild climate prevails without large quantity precipitation. The main part of the Russian territory is located in an area of high snow load, so this construction technology began to be introduced recently, when modern roofing materials with improved performance characteristics appeared. Over the past ten years, one-story buildings with a flat roof have been tested in the harsh Russian winters and have demonstrated the following advantages over their pitched counterparts:

Space saving. One-story houses with a flat roof, built according to frame technology, due to rational use seats are a compact design that can be placed on a small construction site within the city or in the suburbs. This quality is relevant in the context of a constant increase in the cost of land for development.
Saving materials. A flat roof does not have a slope, so less roofing material is spent on this type of roofing than on pitched analogues. Less wood is used during construction rafter frame, which reduces costs. In addition, small flat roofs can be installed yourself without spending money on hiring professional roofers.
Possibility of expanding the area. A one-story house with a flat roof can become a transitional option until the need and financial opportunity arise to add a second floor. This versatility will be an additional advantage for young families, the composition of which may soon change.
Wide range of roofing options. If a one-story house is equipped with a flat usable roof, it can be equipped with additional space to satisfy a variety of needs: equip sports grounds, recreation areas with barbecues, swimming pools, lay out lawns, beds or flower beds. For conservation-conscious homeowners natural resources, designs of houses with a flat roof on which solar panels are installed to provide “clean” energy are suitable.

Note! Roofing materials based on cardboard and bitumen impregnations used in the past had a service life of only 5-8 years, were damaged by exposure to sunlight, and cracked due to sudden temperature changes. But coatings made from fiberglass and synthetic rubber with polymer resins, will protect the house for 50 years. New generation materials are not needed for flooring gas-burner, so they are suitable for DIY installation.

A roof that has no slope is called flat; it rests on all 4 load-bearing walls Houses. This design is a multi-layer coating of rolled or self-leveling waterproofing materials laid on a prepared base. Installation flat roof do it yourself using the method of layering, pouring or gluing in the following sequence:

Base. The first layer of a flat roof is a base made of concrete slabs, wooden beams or corrugated sheets, which are prepared in a special way. A primer is applied to it to reduce surface roughness and increase material adsorption.
Screed. Screed from cement-sand mortar serves as a leveling layer, with the help of which the roof is sloped, creating a slope in the places where water inlet funnels will be installed.
Vapor barrier. This layer of diffuse membrane roofing is a barrier to water vapor that penetrates from the heated room into the thickness of the roof, causing the insulation to become damp. To give the membrane strength, it is reinforced with fiberglass.
Thermal insulation. To protect a one-story house from cooling and heat loss through a flat roof, they install thermal insulation material. For this, backfill insulation (expanded clay), glass wool, basalt fiber, slag wool or extruded polystyrene foam are used.
Waterproofing. Waterproofing of modern flat roofs is carried out using polymer rolls or self-leveling materials. Roll coverings laid in several layers to prevent leaks in the connecting seams. Bulk materials ( liquid roofing felt, liquid rubber) allow you to waterproof roofs of complex configurations; pre-heating is not required during their installation.

Important! The quality of installation of a flat roof on a one-story house depends on weather conditions. Experienced roofers and manufacturers recommend laying the coating when dry, warm weather when the temperature exceeds 5 degrees. At low temperatures, the lower layer of bitumen materials takes longer to heat up, so installation takes longer and gas consumption increases.

Types of flat roofs

Single-pitched houses with a flat roof fit organically into the urban landscape and look just as good as a country residence. Abundant glazing, use in decoration natural materials make the structure light, filled with light and spacious, despite its small size. Depending on the nature of use and financial developers, the following types of flat roofs are used in projects:

Important! The flat roof around the perimeter is fenced with a parapet, a protective barrier that holds snow masses and rainwater from a spontaneous discharge. On exploited roofs, the parapet acts as a fence that prevents people from falling, so it must have a height of at least 1.2 m.

Video instruction

The use of wood as the main building material already increases the volume of living space, but frame houses with an exploited roof they went even further. A full-fledged recreation area right on the roof, a wonderful view of the garden, the opportunity to arrange the best sunbath hot summer day. This one has architectural solution a lot of obvious and hidden advantages.

Advantages of projects with an exploitable roof

Price of one-story and two-story projects houses with exploitable roofs will be lower traditional options. Since the surface area itself will be smaller, material costs are reduced accordingly.
The construction process will be completed in the shortest possible time. In just a couple of months you will be able to start interior decoration premises.
When ordering a house project with an exploitable roof from the company " Summer Season", you can agree on adjustments with our specialist. The final version will 100% meet your needs. Roof garden, table for relaxation, even barbecue area. For modern designers, nothing is impossible.
It is much easier to install an air conditioning system on a flat roof, satellite dish or solar panels.

A house with a flat roof, in a row of similar “boxes” with a pitched roof, looks fresh and unusual. Therefore, every year the number of suburban residents who are seriously considering the construction of such a house for permanent residence is increasing. Fans of “cubic” design are captivated by the wow effect and increased attention from neighbors. Someone wants to place engineering equipment on the roof, or lay out a lawn and arrange recreation areas. Still others believe that building a house with a flat roof is cheaper and easier than with a pitched roof. Is it really? Let's consider the main pros and cons of these buildings and draw a conclusion whether they are suitable for our country. To do this, we will answer the following questions:

Why is it difficult to choose a suitable plot for a “cubic” cottage?
Is it true that flat roofs are not suitable for our climate?
Why does a flat roof leak?
A flat roof is simpler and cheaper than a pitched roof - this is a myth
Why is a flat roof difficult to repair?

1. House with a flat roof and domestic realities

Most country residents look at cottages with flat roofs with skepticism, calling these houses “boxes”. Why? Houses with flat roofs came to us from abroad. Traditionally, they were built in countries with warm climates, where there is practically no winter, heavy snowfall, severe frosts with sudden thaws, prolonged rains, but strong winds blow. For example, somewhere on the Mediterranean coast. Then these houses turned into fashion design erotic trend “not for everyone” in Western Europe, and from there they already came to us.

I see that we mainly build houses with a pitched roof. But is this really necessary? In Germany and Switzerland, designs for houses with flat roofs have long been offered. What could be the disadvantages of a flat roof, besides the supposed unaesthetic appearance?

Indeed, can anyone be left indifferent by the cottage with panoramic windows in the photo below?

Or this high-tech house with a flat roof in the forest.

Or a cottage with a roof made of Observation deck, there is a lawn and a place for relaxation.

Now imagine these houses here. Harsh winter. In an ordinary - not elite village, where roads float in spring and autumn, and plots are fenced with corrugated sheets. Most houses are finished with siding or lined with facing bricks. And pitched roofs are covered with slate, metal tiles or, less commonly, a more expensive solution - flexible tiles. The picture doesn't add up. Something's missing, isn't it? I no longer want to sit on the flat roof of a house, as I dreamed of, with a cup of tea or coffee. After all, from there the view opens not to the ocean, sea, mountains or nature untouched by man, but to dense village buildings or, in best case scenario, fields overgrown with grass.

A house with a flat roof, in a high-tech style, looks advantageous only on a spacious isolated area, for example, on a slope, with beautiful view to a forest, lake or river. A cottage with a flat roof is lost without landscape design, and among good-quality, but similar houses, it looks like a “black sheep.”

This is where it lies the first "pitfall" - dreams of stylish home flat roofs break when you realize,how much will the plot cost?, on which the cottage will look just right.

When you plan to build a house with a claim to a non-standard foreign design, select an appropriate site for it.

2. Reliability of a flat roof in our climate

When you look at beautiful houses, which are hundreds of years old, ask yourself why they were built this way and not otherwise. Why do houses built in coastal zone Somewhere in Norway, Sweden or Scotland the roof does not have overhangs and the usual drainage? They are simply not needed due to strong winds that turn rain into a horizontal stream of water hitting the walls. The same goes for houses with flat roofs. They were built in warm climates, where there is little precipitation but strong wind load.

A flat roof is more wind resistant than a pitched roof.

Our ancestors - smart people. They considered the design of the house from the point of view of practicality, based on the climatic conditions of their residence. Why in Central Asia did you build flat roofs? On the Central Russian Upland are they sloped? In the Baltics, not just slopes, but with acute angle skate? Pitched roof with a slope of 45 degrees, in the Moscow region or Saratov, will provide reliable protection from rain or snow for 20-25 years, even if covered with cheap corrugated board or slate.

A flat roof, with the right approach to construction and using modern materials, will also provide reliable protection for the house from precipitation and will not leak.

The only question is how much 1 sq. m. will cost. m of such a roof with a guarantee that it will not leak quickly during frequent crossings of 0. Icing. Night freezing and daytime thawing of snow cover. Lingering downpours. And most importantly - how to make a roof so that it lasts a long time in our climate?

The second difficulty in building a cottage with a problem-free flat roof is the harsh Russian operating conditions.

3. The main problem of building a reliable house with a flat roof in the Russian Federation

link82 Member of FORUMHOUSE

The company built me a house with a flat roof. We made 6 pieces along the edges. heated funnels and led out to the sides, through the parapet, and drain pipes. Is it correct? Maybe it was necessary to make a slope to the center and, with a small roof area, install two funnels instead of six? And put the pipe inside the building. Discharge in the basement and then into the storm drain? I am afraid that the knee that is being taken out of the funnel into the street will freeze. Ice has already formed on the pipes. What if the pipe bursts due to frost? How to fix it? Throw in a heating cable? So much money has already been spent on this roof!

The house with a flat roof was built in 2013.

In addition to problems with drainage, another one was added. When link82 I came to check the house and discovered that the roof was leaking in several places. Water came from the second floor to the first. All the drywall floated. Now you have to quarrel with the builders. Trying to take the money and completely redo the roof. According to Mikhail-snabss(the portal user is professionally engaged in the construction of flat roofs) in this example is assembled a whole bouquet errors. The main one is builders who simply don’t know how to make flat roofs correctly.

When building a house with a flat roof, do not go cheap. Every step of builders and stage of work needs strict control. More careful than when constructing a pitched one. Mistakes will be costly!

The roof was most likely made of a built-up waterproofing material - glass insulation. The tree played and the fiberglass tore. Repairing this roof with a special roofing membrane will cost from 130 to 200 thousand rubles.

The third factor complicating the construction of a cottage with a flat roof in the Russian Federation - lack of highly qualified builders who know exactly how to build just such houses correctly. How to use and combine materials with each other. What tools are needed for this? Even if the future owner of a house with a flat roof has a detailed design, and he should be, then everything can be ruined by “specialists” who work on the principle: “we always build this way and no one has complained yet!”

Flat roofing should only be done by professionals.

4. Is a flat roof cheaper and simpler than a pitched roof?

Usually, when it comes to the advantages of a flat roof, you can hear the argument that it is cheaper than a pitched roof. Why? Smaller area means lower consumption of materials. It’s easier to make an overlap, because no need for classic rafter system. There is no need to equip the attic floor, etc. And that's true, but as they say, the essence is in the details.

If we take a simplified look at the “pie” of a flat roof, then on the basis, for example concrete plates ceilings are laid:

vapor barrier;
thermal insulation;
waterproofing.

Or the so-called inversion flat roof, where the layers go like this:

waterproofing;
thermal insulation;
finishing layer.

In an inversion flat roof, the waterproofing layer is located under the insulation and “works” in more gentle conditions, because from above, from negative influence weather conditions, it is protected by crushed stone, tiles or soil with a lawn. Those. a ballasted flat roof is installed.

But, when building a flat roof it is necessary:

Arrange slopes for water drainage - about 2 cm per 1 linear meter. Slopes are usually made with concrete screed or wedge-shaped insulation elements.
Lay several layers of insulation. If used stone wool, rather than extruded polystyrene foam, install aerators to remove water vapor from the thermal insulation.
Put water inlet funnels with electric heating, otherwise, due to the ice that has formed, they will not drain water from the roof.

One water intake funnel, with a diameter of 110 mm, drains water from an area of up to 300 square meters. m.

Mount drainpipe with a slope of 3 cm per 1 linear meter.
Make high-quality waterproofing from PVC, TPO or expensive EPDM membranes. TPO membranes They are less elastic than PVC membranes, but at the same time have higher strength. Welding TPO membranes requires professional installers with special equipment. The advantage of EPDM membranes is the large format, and the smaller welds, the more reliable the flat roof.

When installing a flat roof, you will have to take into account many nuances.

Calculate the snow load depending on your region of residence. For example, Moscow and St. Petersburg belong to the third climatic region. The snow load on a flat roof, with a slope of 2%, in the Moscow region will be 180 kg per 1 sq. m. m. In the fourth climatic region, the snow load is 240 kg per 1 sq. m. m, and in the fifth there are already 320 kg. Do not forget that the weight of 1 m 3 of loose, freshly fallen snow is on average 50 - 100 kg. The compacted one is already 350 kg. A cube of wet or melting snow weighs approximately 400-600 kg.

There is no need to remove snow from a properly designed flat roof in winter. The excess is blown away by the wind, and the loose snow becomes a heat insulator.

But the load on a flat roof must be taken into account with a greater margin than on a pitched roof, taking into account force majeure circumstances. For example, the water inlet funnels became clogged, the heating cable burned out, and the water did not drain from the roof. A month's worth of snow fell in a couple of days, but there was no wind to blow it away and it lies on the roof. Additional weight on the roof puts pressure on the walls, which in turn transfer the load to the foundation, which redistributes it to the soil foundation. The further north you go, the greater the load. Add a lot of crushed stone or soil with grass if you are installing a ballasted flat roof.

From here - The optimal design for a cottage with a flat roof is not a frame or wooden house, but a stone structure, calculated by the designer and built from aerated concrete, brick, warm ceramics, By monolithic technology. Because “Cubic” design involves large unsupported spaces, then it will no longer be possible to block a span of more than 6 m with a tree. Trusses, I-beams, wooden I-beams, hollow reinforced concrete floor slabs, monolithic ceiling or prefabricated monolithic floor. Don’t forget to add expensive façade finishing solutions to the cost of a house with a flat roof.

You can't finish a house like this cheap anymore.

Planken, burnt wood, hand-molded bricks are used, wet facade, combined facades made of wood and stone. And you can’t put it in a house with a flat roof. standard windows. Large or panoramic are required. Add to this additional areas parapets, which also need to be insulated and finished. This increases construction costs.

The fourth factor - a house with a flat roof cannot be called budget construction.

Consider the costs not only for the roof, comparing the final estimate with flat and pitched ones, but for the total cost of the entire “box” with finishing.

5. Low maintainability of a flat roof

sv2321 User FORUMHOUSE

I have a house with a flat roof. Waterproofing - membrane. I'm struggling with the roof. As they say, water will always find a hole. I like the flat roof, but I think I’ll give it up and convert it to a pitched roof, although I’ll have to change the entire architecture of the house. And that's why:

There is no absolute guarantee that all joints of a flat roof will be airtight. Enough microcrack and off we go. If there is a bias, then minor defects not critical;
Snow lingers on a flat roof. He's melting. Water fills microcracks. It was frosty at night. The water is frozen. With frequent daily freeze-thaw cycles, microcracks enlarge and then rupture. They are getting bigger. The pitched roof has no welded areas and there is nothing to tear there. In the worst case scenario, a small temporary leak will appear without progressive consequences. It is easy to find and repair;
The most unpleasant thing. On a flat roof, you will never know exactly where the defect occurred. There is a leak in one place, and water is dripping from the ceiling in another. The craftsmen will come, check the joints and find one of the defects, but the rest will remain. If the roof is inverted or loaded with gravel, then defect detection is an even bigger problem.

According to the user, optimal roof for our climate - pitched. The angles of the slopes compensate for the crooked hands of the builders and changes in the properties of materials over time, and the overhangs protect the walls and finishing from precipitation.

So, fifth - low maintainability. The quality of a flat roof is greatly influenced by the human factor.

If it leaks pitched roof with a cold attic, it is not difficult to find and repair the defective area. As a last resort, you can dismantle the coating and perform local repairs or get close to problem area from the inside. In the case of a flat roof, finding a leak and repairing it becomes more difficult due to the complex “pie”. Many layers in the structure, especially in the so-called. "green roof". Availability concrete screed etc.

conclusions

Houses with a flat roof certainly look beautiful and stylish. Make a flat, problem-free roof that will serve long years in our climate also possible. The only question is the total cost of all decisions and its feasibility. Anyone who has been involved in roof installation or repair in our climate knows that in the summer, a hot roof in the sun is the last place you would want to sit with your family or friends. It's hot and stuffy. I want to quickly go into the shadows. If there are small children in the house, then a used flat roof is an extra headache for parents. You can also organize a shaded private place to relax with barbecue on the site small area. It’s nice to sunbathe in the garden on the grass, throwing in a towel or laying out a sun lounger, and not in full view of all the neighbors and passers-by on the roof. In the countryside, you simply want privacy, and not to show off your privacy for everyone to see. Let's add our changeable weather. Rain. The wind, which at altitude is felt completely differently than below. In total, how many days a year will there actually be left to relax on a flat roof? Let's add the need to arrange a place to access the roof directly from the house. Do not climb onto a flat roof using a ladder that is attached to the facade. What's left? Unusual “fashionable” design to attract attention. Therefore, let everyone decide for themselves whether to build a house with a flat roof or not, and FORUMHOUSE offers you proven solutions for this.

Houses with a flat roof were rarely found in our country. However, today projects of houses with a flat roof have begun to be considered again, so it is worth paying attention to their advantages, disadvantages and features. This article will talk about the advantages and disadvantages of such projects, the features of laying a flat roof and design options for the roof space.

The reason for the increasing popularity of flat roofs today is modern design trends. This was also facilitated by the emergence of new building and roofing materials, which made it possible to create not only pitched or hipped roofs, but also high-quality flat roofs.

Since the flat roof structure has some differences from other traditional options, the construction technology will also differ. First of all, this concerns surface waterproofing, as well as the drainage system.

When considering the idea of creating a flat roof in a private house, it is worth paying attention to the following advantages of this solution:

if, then such a roof will fit perfectly into general form. They look original square houses with a flat roof and rectangular;
building a flat roof requires less time, since it has a smaller area, so working on such a surface is easier and more convenient;
the flat roof provides the opportunity to utilize this additional space. For example, a cozy terrace can be equipped upstairs;
when it comes to maintenance, there is nothing easier than working on a flat roof. There is no need to involve steeplejacks to clean up wastewater or ventilation ducts. Almost any flat roof repair can be done by the owner himself;

The flat roof space can be used by the owners not only as a recreation area, but also for installing various specialized equipment. For example, many people want to install solar panels as alternative source receiving electricity. The same applies to wind generators, all kinds of heaters and systems designed to collect rainwater.

The nuances of constructing houses with a flat roof: photo examples

Speaking about the shortcomings and difficulties associated with the implementation of projects modern houses with a flat roof, it is puzzling that despite the significantly smaller area, as well as the relatively low cost of roofing materials, it is no cheaper to build a flat one.

This is due to the fact that a flat roof necessarily requires high-quality reinforced concrete floors. This issue is especially relevant if the roof surface will be used. Using this space creates a significant load on the entire structure of the house, including the foundation and walls. Thus, savings on the roof lead to an increase general estimate building a house.

It is impossible to unequivocally answer the question of how to solve the problem of snow accumulating on the roof surface. There is an opinion that the snow layer has some positive influence, creating additional thermal insulation, which leads to a reduction in heat loss. But we cannot ignore the fact that snow is an additional load on the building.

We often have to deal with the fact that if the roof seal is broken, the process of snow melting is accompanied by roof leakage. To avoid this, you must initially ensure that the materials for waterproofing the flat roof are of high quality and installed in accordance with the requirements and recommendations.

Projects of houses with a flat roof: types of structures and their purpose

Modern flat roof houses may vary depending on the type of roofing. Accordingly, this will affect construction methods and further operation of the surface.

The roof space allows owners to regularly be on its surface, as well as install various objects without the risk of damage. The base of such a roof must be as rigid as possible, so reinforced concrete is most often used for this purpose. Special requirements are also placed on the heat insulator: it must be resistant to severe loads and also have high compressive strength.

Unused roofs are not designed for heavy loads. In this case, replacement is acceptable concrete base to less durable wood. In this case, a house with a flat roof is equipped with special bridges or ladders, which reduce the load on the surface and prevent damage if it is necessary to move along the roof.

Inversion roofs are a special type that provides for the location of insulation above the waterproofing layer. This allows you to protect the bottom layer from exposure external factors: temperature changes, sunlight and mechanical loads. It also increases the number of permissible melting and freezing cycles of the material.

In most cases, this type of roof is used as a serviceable one, since you can move freely on it, as well as install moderately heavy pieces of furniture and decor. Moreover, this type of roof is considered the most durable among others.

Important! Regardless of the type of roof you choose, you should ensure that you have a suitable drainage system. There are special external drains for flat roofs that can effectively solve the problem of water accumulation.

Options for installing a flat roof of a private house: how to use the space

Considering the fact that every square meter of territory has its own cost, you have to save money by using space rationally. And in this matter, flat roofs occupy one of the leading positions. Indeed, in the case of arranging a used roof, the owners actually receive another floor, albeit subject to seasonal use. Today, even frame houses with a flat roof are on sale.

This solution may allow you to abandon the traditional veranda if the size of the plot is not too large. For many owners of small plots great solution the arrangement of a roof garden is becoming.

Other common options for using a flat roof include creating a recreation area, such as a gazebo. With a flat roof, the dream of a setup or barbecue becomes possible.

Another very interesting option is to install a swimming pool on the roof. Of course, this will require considerable financial costs, as well as a large amount of work associated with calculating the upcoming load. However, if you entrust this to professionals, you can get an excellent place to relax. As an example, you can look at several photos of one-story houses with a flat roof equipped in this way.

Helpful advice! In order to create a special atmosphere and comfort on the roof, you should take care of the availability good lighting. It may be small Spotlights or garlands. The main thing is that they are designed for use in outdoor conditions.

Another original solution for arranging a one-story house with a flat roof is playground. For a small house, suitable option installation of exercise equipment or arrangement of a basketball court. For larger houses, designers provide even more original solutions. So, you can find projects two-story houses with a flat roof, which are equipped with a tennis court and a helicopter landing pad.

How to make a flat roof: features of construction technology

When talking about houses with a flat roof, you need to understand that they still have some, albeit slight, slope. Usually this figure does not exceed 5o. But this slight slope is very important as it allows rainwater to flow towards the drain.

Since a flat roof consists of many layers, in the process of laying them it is necessary to strictly observe not only the technology, but also the time intervals. The quality of materials also plays a big role. Therefore, saving in this matter is highly not recommended.

Let's look at what each layer of the roof pie consists of, and what you should pay attention to during the construction process.

Rigid base. As already mentioned, if the roof is planned to be used, it is usually made of reinforced concrete. As preparatory work the base is thoroughly cleaned and then leveled. For this purpose they use cement screed, as it perfectly eliminates all small crevices, cracks and chips. At this stage, it is important to wait until the solution has completely dried before moving on to further work.

Vapor barrier layer. As vapor barrier material For flat roofs, a bitumen-polymer film or vapor barrier is usually used. The main task of this layer is to provide reliable protection against moisture and condensation, preventing them from entering from inside the building to building materials. At this stage, it is important to seal all joints and seams as thoroughly as possible, since they pose the main danger.

Insulation. This layer directly determines the life and quality of operation of a flat roof, and therefore its features are worth dwelling on separately. Unlike pitched structures, V in this case there is no space under the roof. Usually it serves as additional thermal insulation, so the importance of high-quality insulation greatly increases.

The most popular material used for this purpose is mineral wool. Due to the presence of such characteristics as fire safety, long term service, resistance to moisture and steam, as well as compression, this option is almost ideal.

Another advantage that mineral wool has is that a layer of waterproofing material can be laid directly on top of it. Usually to improve thermal insulation characteristics flat roof, use a two-layer insulation system. In this case, the lower layer takes on the main thermal insulation function, while the upper layer serves for distribution. You can learn more about this by looking at several photo projects of one-story houses with a flat roof.

Features of choosing waterproofing material for a flat roof

For waterproofing, a durable, stable and elastic material is used that is not affected by temperatures and microorganisms. In case of arrangement of unexploited roof will do bitumen or roofing felt, in all others it is better to give preference to more modern materials, for example, PVC membrane.

Interesting! Modern waterproofing materials are able to withstand heavy loads, which becomes an advantage when arranging a roof garden.

There are several options for solving this problem:

penetrating (diffuse) membrane;
EPDM membrane;
waterproofing agents that are applied by spraying, for example, liquid rubber;
PVC membrane.

Given that high-quality styling and compliance with all recommendations, the service life of such materials will be up to 30 years. In addition, practically no mechanical impact can damage them.

If we talk about which of the listed options is better, then the PVC membrane takes the leading position. Due to the fact that they are made of polyvinyl chloride, they are lightweight, do not catch fire and are extremely resistant to ultraviolet radiation.

Helpful advice! If we are talking about arranging a roof that has a complex geometric structure, it would be more effective to use it as waterproofing. liquid polymers. This will avoid the presence of seams. It is also better to use soft roof. The technology for installing a flat roof in this case is greatly simplified.

Features of arranging a drainage system in house projects with a flat roof: photos

The most important factor determining the service life of a flat roof is the quality of the drainage system. This is necessary to eliminate the risk of water stagnation on the surface and, as a result, damage to materials. The house design can include one of two systems – internal or external.

Sometimes, in order to prevent the accumulation of snow and ice in the drainage system, they are additionally equipped with heating, which consists of a special cable that heats up.

Due to the presence of a slight slope, water enters the drain funnels and is then drained away from the house. At this stage, it is important to pay attention to the quality of waterproofing of the junctions of the elements with the roof. This allows you to keep the design of the facade of a house with a flat roof in original form and prevents erosion of the foundation.

Helpful advice! In order to prevent clogging of the drainage system, it is recommended to ensure the presence of a special mesh that will serve to “catch” debris.

House with a flat roof: catalog of projects and features of the implementation of original ideas

Plants planted directly on the roof surface, rather than in pots, look incredibly impressive on the roof of a house. But this technology has its own nuances, which you need to familiarize yourself with in advance.

A layer of geotextile is placed between the drainage and the soil. This prevents the process of soil being washed out into the drainage, as well as its washing. This is facilitated by the dense arrangement of synthetic fibers.

If planting is not planned, the procedure is somewhat simplified and can be reduced to applying a concrete screed, on top of which tiles will be laid or a special sand-gravel mixture will be poured. Which option is preferable depends on how the roof will be used in the future.

Considering the projects of one-story houses with a flat roof, you can see how important the presence of such additional space plays. If the area is properly equipped, this place can become a favorite place for the whole family. In addition, this idea can be implemented for other buildings. For example, you can make a bathhouse with a flat roof or a gazebo.
