The best way to cover the roof of a house - how to choose roofing material. Re-roofing a house: composition of the roofing pie and selection of materials Re-roofing a house

Not everyone decides to re-cover an old roof on their own, considering this work to be complex and difficult. Of course, these people are partly right. However, there is a noticeable desire to maintain family budget forces many to “cross the Rubicon.” To proudly declare that I rebuilt this roof with my own hands, you need to study the instructions I offer, familiarize yourself with the specifications of the materials used and select the necessary reconstruction option.

What elements does the roof of a house consist of?

The roof is general concept a structure that covers the space above your head from precipitation, sunlight and other external influences. In private house construction, a roof means a multi-layer structure located on special mounting units - beams, joists, which, in turn, are attached to the walls and ceilings of the house. A roof consisting of a number of layers of different materials is called roofing pie.

The overall roof design and the cost of constructing or repairing it largely depend on the roofing materials that will be used. At the same time, regardless of their characteristics, general scheme roofing pie consists of the following elements (listed from bottom to top):

1. Rafters are the supporting beams on which the entire structure rests. Depending on the roof configuration, they can form one or more slopes. The most popular roof option is a gable roof. In it, with their lower ends, the rafters rest on the mauerlat - a wooden frame around the perimeter of the wall, and top ends form the vertices of a triangle.
2. Vapor barrier. It is needed so that moisture from interior spaces did not penetrate into the insulation. It is hammered from the inside to the rafters. It doesn’t matter what kind of room is under the roof - cold attic or a heated attic - due to the temperature difference, condensation always forms inside. Layer vapor barrier film prevents it from getting into the insulation and other components of the roofing cake.
3. Insulation. Even if there is no living space under the roof, but only a cold attic, insulation is still needed, since up to one fifth of the heat is lost through interfloor covering and roofing. Mineral wool has gained great popularity as roofing insulation. It is environmentally friendly, non-flammable, and lightweight. One thing is bad: it loses its properties when exposed to moisture, which is why it must be covered with membranes on both sides. Mineral wool slabs are very convenient to lay between the rafters.
4. Waterproofing also acts as a membrane, only, unlike the bottom film, this material allows steam molecules to pass through, but water will not pass through it. The order “waterproofing from above, and vapor barrier from inside the room” is very important, otherwise the insulation will get wet over time.
5. Counter-lattice. These are slats that are packed along the rafters. They have a dual function: they ensure a tight fit of the waterproofing to the rafters, and also provide ventilation gap between the membrane and the final roofing covering. When using corrugated sheeting, seam roofing, metal tiles, etc., condensation is formed, which must evaporate when air passes through the ventilation gap.
6. Lathing. It consists of slats, boards or a solid covering, but already packed across the rafters. Installation is carried out directly on it finishing coating. In the case of using rigid materials, sparse lathing is used. Soft roof requires the arrangement of a solid substrate, which is sheet plywood or OSB boards.
7. Finish coating. It is called so because it is laid last. It will take on all the influences environment: precipitation, sun rays, wind, so you should approach its choice responsibly.

Choosing material for roof replacement

The owner of the house himself chooses what to cover the roof with, based on his own taste. However, it is worth taking into account the technological features of installation. At self-installation There are “easy” and “problematic” materials. For example, ceramic tiles requires skill in installation, and it is necessary solid foundation, so it will not be easy for a beginner to properly arrange a roof out of it. If the house has a roof of complex configuration with rounded elements, then it is foolish to try to cover it with slate or corrugated sheeting - for this they use bitumen shingles. However, each material has its own characteristic features.

Properties of metal tiles

Metal tiles are one of the most convenient roofing materials for DIY installation. Its weight is not very large, the sheets have acceptable sizes and are convenient for installation. The wavy surface of metal tiles requires relatively frequent lathing to prevent the steel from bending.

The sheets begin to stack from bottom to top. Adjacent surfaces are mounted overlapping the width of one wave - this avoids the penetration of moisture and wind under the roof. The metal tiles are attached to the sheathing using galvanized self-tapping screws with a double washer - steel and neoprene, which serves to seal the hole. This makes the fasteners of metal tiles similar to corrugated sheets. The durability and decorative appeal of the coating are ensured by the coloring layer and multi-layer coating.

Features of corrugated sheets

Corrugated sheeting is the closest “relative” of metal tiles. The difference is in shape: corrugated sheeting is produced by cold rolling through rollers, so rectangular waves alternate with grooves. For the roof, take corrugated sheeting with a wave height of at least 20 mm, which is appropriately marked.

The design turns out to be durable, but it must be handled carefully - a scratch on the surface can create a source of corrosion, and after some time the sheet will have to be replaced.

Battles between supporters rage online different schemes corrugated sheet fastenings. Some argue that you need to tighten the screws between the waves, others - that into the wave. In fact, both methods have their place, each has its drawbacks. The screws between the waves are in the path of flowing water, which means that the risk of leaks increases if the neoprene washer wears out or is installed incorrectly. To twist into a wave, you need a longer self-tapping screw, and if the tightening force is exceeded, the steel may become deformed.

Pros and cons of soft tiles

Soft or bitumen shingles- this is fiberglass, on which a resinous adhesive coating is applied, and on top on one side there is granulate - small particles hard material, which increase wear resistance. Pieces soft tiles made with jagged edges to create the effect of real tiles.

Installation of bituminous shingles is carried out on a solid base made of plywood or OSB boards. They spread it on top underlay carpet, and then overlap the shingles. They are fixed with nails with wide heads. Thanks to the bitumen base, the tiles additionally stick to the base when exposed to sunlight.

The advantages of the material are complete waterproofness and resistance to rotting or corrosion. The soft roof does not rattle in the rain. It has only one disadvantage - high cost, since creating a solid base with an underlay carpet greatly increases the price of this option roofing covering. The experience of my Canadian friends suggests that over time outer sheets are torn off by the wind, so they have to be replaced with others.

Characteristics of ondulin

Soft slate, bitumen slate - this is also what this material is called. It is completely identical to slate in shape, but in essence the material is completely different. Its base is cardboard or fiberglass, which is impregnated with bitumen and pressed at high temperature. This is how the leaf acquires a characteristic wavy surface. Like slate, ondulin is attached to nails with wide heads and washers. The lathing for ondulin does not have to be continuous, but frequent - with a pitch of transverse slats of at least 40 cm.

Good old roofing felt

Ruberoid became famous much earlier than other modern roofing materials. It is based on cardboard impregnated with bitumen and sprinkled with stone granulate to preserve properties and protect against external influence. Today, roofing felt has been improved: fiberglass is used as a base, which increases strength, including tensile strength. Manufacturers, in order to announce innovations, call such material euroroofing felt or glass insulation.

A roll of roofing felt rolls out over the surface and heats up. gas burner with a long nozzle or blowtorch. The bitumen is melted and glued to the continuous sheathing. The roll is rolled out along the ridge, starting from the bottom strip. If the roof is very steep, rolling is carried out across the ridge, additionally coating the joints with bitumen.

Familiar slate

Another old-timer among roofing materials has been familiar to us all since Soviet times. It hasn't changed much since then. It's still a cheap, hard, heavy corrugated material that doesn't have any tensile properties. The advantage is the ability to reroof with a small budget and lack of experience as a roofer.

Seam roofing

This option is one of the most durable, reliable and at the same time expensive. Seam roofing is metal sheets that are laid on the sheathing and fastened into a special lock - a seam. In this case, the edges of adjacent sheets are bent in such a way that completely eliminates the penetration of water. The roofs of old European houses, which are hundreds of years old, are either tiled or seam.

How much does it cost to re-roof

Of course, before you start re-roofing, you need to resolve one of the main questions that arises for the owner - how much will it cost to replace a worn-out roof.

The approximate cost will be indicated taking into account the rework of all roofing components, except for the rafters themselves. That is, you will need to replace the insulation, vapor and waterproofing membranes, the sheathing that could rot, and the coating itself. If you estimate the total cost of a house 10 by 10 m s gable roof with an angle of 35 degrees along the slope, then the total area will be 120 square meters. m. The list of estimated costs will be:

Dismantling the old roof. Price in different regions Russia may vary, the average value at 2019 prices will be about 270 rubles. per sq. m. That is, the entire roof will be removed for 32.5 thousand.

Insulation. Mineral wool boards- this is about 2100 rubles. per square, plus installation will cost 100 rubles. The total for the whole house is 265 thousand rubles.

Flooring waterproofing membrane will cost 160 rubles per square, and about 90 more will be required for the work itself. In the amount of 30,000 rubles. A new counter-lattice will cost about 30 thousand rubles.

Metal tiles (as a medium-cost and highly reliable material) will require an investment of about 420 rubles. per sq. m, and even 300 rubles. for work. Result: 86,400 rub. The total cost of roofing work and materials will thus be about 450,000 rubles (with a small reserve for overruns and unforeseen circumstances).

Work before roof renewal

If a decision was made to block old roof, then the work must follow a specific plan to avoid damage to the surviving coating, cost overruns and compliance with safety regulations.

Removing the topcoat. Usually this is enough hand tools, but you can also use electric. Roofing nails are removed with a nail puller through the backing. The screws are unscrewed with a screwdriver. Flexible roof you will have to tear it off, prying it with a spatula or crowbar down to the solid base.

After dismantling the covering, a thorough visual inspection of the membranes, insulation and rafters is carried out. Wooden parts must not be rotten or moldy. They look for traces of moisture on the rafters. The membranes are inspected for damage to integrity, which could lead to the insulation getting wet. If punctures and cuts are found, remove the membrane, take out the insulation and change the area that was wet.

A rotten section of rafters or sheathing must be replaced. This is easy to do one at a time, as long as all other elements securely hold the structure in the desired position. After replacement, the usable insulation is put back in place, the damaged one is replaced with fresh one. Rolls of waterproofing are rolled out again along the ridge, starting from the bottom, the joints are taped and pressed against the rafters with battens. Thus, covering an old roof comes down to replacing damaged elements with new ones.

Laying a new roof over an old one with your own hands: simple and inexpensive

If there is an old one on your house slate roof, which is leaking, fragments are split or displaced, it is not at all necessary to disassemble it all and do it completely again. More economical and easier to install new roof on top of the old one.

You won't need many tools: a hammer, a wood saw, a screwdriver. As a finishing coating, we will consider ondulin, including the ridge corner. You will also need timber for additional sheathing, screws and nails:

A situation often arises when even newly built houses need to be reroofed, not to mention buildings that were erected a long time ago. Such a need may arise due to leaks, sagging, heat loss, etc.
No less often this service required simply because you need to replace the old roof with a new one. In any case, the owner is faced with a choice - turn to specialists, or solve the problem on his own.

To perform work, in addition to knowledge of theory and special tools Practical skills will be required, without which it will simply not be possible to successfully carry out all the operations necessary to obtain the result. By entrusting this work to professionals, you ensure a long life for the roof of your home.

Covering the roof of a house

The complex of roof covering works is carried out in several stages, each of which requires the utmost precision in execution.
To do this, it is necessary to have knowledge of the main functions of the roof, namely protective, sound and heat insulation and aesthetic. You also need to have an idea of ​​all the components roofing structure, which is traditionally called “roofing pie” - base, thermal insulation, vapor barrier, roofing material.

All this knowledge is fully possessed by the specialists working in our company “Zvezda Roofing”

Main stages:

• installation of sheathing;
• waterproofing and vapor barrier device;
• roof insulation;
• laying roofing material.

The first three stages are common to all types of work. The fourth has its own specifics depending on the chosen material.

However there are some general rules which must be used when working with any roofing materials:

• Roofing material should be laid from bottom to top (except hipped roofs) with mandatory alignment along the overhang and cornice;
• if the roof slope has a triangular shape, the roofing material is laid from the center on two sides;
• on rectangular slopes, laying can be done both from left to right and from right to left;
• to ensure normal water ingress into the gutters, the roofing material should hang from the sheathing by 5-6 cm;
• If the roofing material is not supplied with special fasteners, screws or nails should be used to install the roofing.

More details about various materials used by our company’s specialists when carrying out roofing work, can be read in the relevant sections of our website.

The roof is one of the main structural elements Houses. Besides his functional purpose, it serves as an excellent means for realizing a design concept. The variety of shapes and the ability to use classic and modern roofing materials will make any home original and attractive.

The main thing that needs to be done immediately before installation is to design the roof structure, preferably so that the roof matches the overall design of the building.

Compliance with the requirements regarding how to properly re-roof will guarantee its durability and aesthetic appeal.

Roofing - quite difficult process. You can do it yourself if you have construction skills. Having decided, you need to know that this process is carried out in several stages:

• installation of sheathing;
• waterproofing and vapor barrier device;
• roof insulation;
• laying roofing material.

To perform roofing work you will need the following tools:

• hammer;
• electric drill or screwdriver;
• roulette;
• marker or pencil;
• hacksaw;
• scissors, electric saw or hacksaw for cutting metal tiles or corrugated sheets;
• special knife for cutting soft roofing materials.

Roofing materials are divided into: mineral ( stone materials, these include tiles, slate tiles, slate);
organic (polymer, bitumen);
metal.

First of all, you need from the many proposals for modern market building materials. It is necessary to take them into account specifications, functionality, texture, price and other indicators. To date most in demand metal tiles, corrugated sheets, flexible tiles (bitumen) and ceramic tiles are used.

Perhaps the most popular among consumers is metal tiles. This material is relatively lightweight, easy to install, affordable, and its shape resembles natural tiles. Wide range of protective colors polymer coating will allow you to choose an option that will harmoniously combine with the style and decor of the building. As an alternative, corrugated sheeting can be used. It is cheaper than metal tiles, less decorative, and is available in the form of ordinary galvanized, painted or coated sheets. These types of coatings are perfect for roofs with simple form. If you need to cover a roof with a complex configuration, then a significant amount of material will end up in waste.

Flexible tiles are the most suitable choice in order to cover curved slopes or roofs of complex configurations with a slope slope from 12 to 90 degrees. It is made of bitumen applied to fiberglass and covered with stone chips. With different shapes (wavy, triangular, rectangular, hexagonal) and rich color scheme, bituminous shingles will ensure long-term operation of the roof in any climatic conditions and excellent decorative look. Despite the rather high price, the use of soft tiles is beneficial due to the virtually waste-free installation technology. In addition, it has excellent sound-absorbing properties and does not create noise when it rains. Its only drawback is that over time this material can fade in the sun.

Natural tiles will be the most expensive. This one is environmentally friendly pure material It is made from clay by firing and can be coated with transparent or colored glaze to enhance the decorative effect. Of course, such a roof will be durable, beautiful, warm and noise-absorbing. Please note that ceramic tiles have heavy weight and requires some experience when installing.

How to make a sheathing correctly

The rafter-beam system and sheathing make up the frame future roof. Rafter structure It’s quite difficult to do it right yourself, so it would be better if this work is done by specialists, but you can install the sheathing yourself. Depending on the chosen roofing material, the quality of the house may vary. For flexible tiles prerequisite is a continuous sheathing made of moisture-resistant plywood or calibrated boards. For metal tiles, corrugated sheets and natural tiles, a sparse sheathing is made of boards and beams, the pitch of which depends on the characteristics of the material and can range from 35 to 50 cm. The sheathing boards are nailed to the rafters across the roof slope.

To correctly install the sheathing, you must remember that:

• when calculating the length of boards or beams, you should take into account the roof overhangs, designed to protect the walls of the house from rain and snow;
• boards and beams must be good quality and have a humidity of no more than 22%;
• it is better to use calibrated material (boards 10 x 2.5 - 3 cm, bars 5 x 5 cm), since the surface of the roof slopes should be as smooth as possible, without protrusions and deflections;
• the joints of the boards or beams of the sheathing should be located above rafter beams;
• for fixing ridge strip two additional boards are attached on both sides of the roof;
• the first sheathing board should be thicker than the others by the height of the roofing material;
• the distance between the sheathing boards and chimneys must be at least 12 cm;
• When covering the roof, nails should be used for lathing, the length of which is 3 times greater than the thickness of the boards for reliable fixation.

To ensure long-term operation of the roof of the house, before starting work, everything wooden elements should be treated with special antiseptic solutions.

Waterproofing, vapor barrier, roof insulation

A properly executed roof covering involves installing waterproofing above the rafters, laying insulation between the rafters, and installing a vapor barrier under the rafter beams. Waterproofing must be done to protect against moisture from the outside. The following can be used as insulating materials:

• waterproofing film;
• absorbent anti-condensation roll materials;
• superdiffusion membranes.

Mounting metal roof at home, waterproofing is done before installing the sheathing (film and anti-condensation materials). Membranes are used only for warm roofs, they are installed on slabs thermal insulation material. Making a roof out of flexible material, after installing a continuous sheathing, an underlay carpet is attached to it.

For the roof of a residential building, it is imperative to use insulation. For these purposes you can use mineral wool, polyurethane foam, polystyrene foam, cellulose insulation. To perform thermal insulation correctly, you need to pay attention to the following:

• the thickness of the insulation should be 10-20 cm, while there should be a gap of 4-5 cm between the sheathing and the insulation for ventilation;
• sufficient frost resistance of the material;
• resistance of insulation to moisture;
• The thermal insulation material must be environmentally friendly, without an unpleasant odor.

A vapor barrier is installed to protect against moisture penetration from the interior of the building, especially in cases where an attic or residential building is planned. attic space. For its construction, special films are most often used: yutafan or isospan. Fix the vapor barrier from bottom to top, making sure that the overlap of the rows is at least 5 cm. The joints between them are fixed using construction tape.

How to properly lay roofing material

Laying roofing material on the roof of the house is the final stage of work. Depending on the selected type of coating, it is used custom technology, requiring compliance with a certain order of work and some subtleties. However, in order to properly cover the roof of a house, you need to adhere to some general rules:

• laying of the covering material is carried out from the bottom up (except for hipped roofs) with its alignment along the overhang and eaves;
• roofing material begins to be laid on the triangular slopes from the center on two sides;
• on rectangular slopes the coating is laid from right to left or from left to right;
• the roofing material should hang 5-6 cm from the sheathing for normal water to enter the gutters;
• to install a coating that does not have special fasteners, use self-tapping screws or nails to better fixation It is recommended to use special rubber seals.

The roof is the most important part of the house and garage, because it is most often exposed to harmful factors (precipitation, mechanical damage, sun rays). Therefore, this is the most vulnerable design. Problems with the roof can affect the condition of the entire building. That is why all owners of private houses need to think about how to cover the roof on their property.

How much does it cost to re-roof a country house?

Below you can see Moscow market prices for roofing in a private house using the example of corrugated sheets, metal tiles and other popular materials.

In addition, you should also consider the cost of related work, which you cannot do without:

• installation rafter system 450 rubles;
• installation of insulation 300 rubles;
• installation of waterproofing 80 rubles;
• installation of sheathing 110 rubles.

At the design stage, specialists pay a lot of attention to the choice suitable type roofs. After all, the selected material must meet all quality indicators. Not bad if it is not expensive. A wide range of coatings can drive an inexperienced builder into a blind corner. However, our masters will do it in an instant necessary calculations and pick up best option. Below we will talk about the most common materials, their advantages and disadvantages.

The first type is built with a slope not exceeding 7 percent. Such roofs are multifunctional, but require a drainage system and moisture permeability. Technologies make it possible to construct a flat surface from transparent materials.

TO pitched roofs are one and the same gable structures: hip (4-pitched), half-hip, attic (allow you to use the attic as a full-fledged room) and multi-gable.

In addition to these designs, spherical and dome options. The combination of several types of roofing is called a combined roof.

We select the roofing material by type, taking into account the following parameters:

• durability – the ability of a material to retain its properties under repeated changes in external conditions.
• price (sum of material and fasteners);
• cost of installation and auxiliary materials;
• appearance;
• safety.

For flat roof

Polymer mastic - new life for outdated technology

The material replaced bitumen (resin), which was preheated and applied to the roof surface. The disadvantage of the method was considered to be harmful to roofers and fragility. Modern “hot” mastics are designed for waterproofing. Mastic, which, unlike bitumen, is sold in finished form, is applied to the roof with a simple roller. The surface is cleaned of dust before application. The material cannot be used if there are cracks.

Advantages:

• low cost;
• low labor intensity;
• operational repair.

Flaws:

• requires surface preparation;
• fragility;
• high heat losses.

The price per square meter with installation is 2 US dollars. Service life – 3 years.

Self-leveling roofing

The principle reminds bitumen mastic. The material is liquid and includes oligomers. The composition is applied in layers to a cleaned surface of concrete, metal or bitumen. When plasticized, it forms a continuous waterproof film.

Advantages:

• exploited surface;
• durability;
• resistance to temperature changes over a wide range;
• quickly installed;
• seamless;
• fireproof;
• harmless.

Flaws:

• requires an ideal surface;
• with a slope above 2.5°, reinforcement is necessary;
• the price depends on the number of layers.

Minimum bulk cost polymer mastic– 5 $. Service life – 15 years.

Flat membrane covering

PVC, TPO and EPDM membranes are used for roofing. Polyvinyl chloride material is not safe for humans, but is resistant to ultraviolet radiation and open fire. Rubber membranes (EPDM) are harmless and durable (reinforced with polyester mesh). TPO is identical in properties to EPDM, but contains reinforced olefins.

Membranes are installed by fastening along the perimeter of the roof. Apply on flat surfaces, for the roof of large buildings.

Advantages:

• water resistance
• large coverage area without seams
• work is carried out at any time of the year
• low labor intensity during installation
• does not require repair
• not susceptible to mechanical stress
• durable

Flaws:

• foundation preparation required
• instability to solvents and oils based on organic elements

The guaranteed service life of the membrane is 50 years. The cost per square meter excluding installation is $6. Installation is calculated depending on the complexity and area of ​​the roof. Price from $3 per sq.m.

Roll welding material

The design replaced the traditional roofing felt. The material is commonly called glass insulation, and sometimes waterproofing. Produced in rolls, the basis of which is fiberglass, fiberglass or polyester. Applied to the base modified bitumen sprinkled with mica, quartz sand or slate. Installed on roofs with a slope of more than 10°. Mounted on a solid base over insulation and a waterproofing layer. The rolls are rolled out over the surface, forming a continuous cover. The material is overlapped. The joints are glued by heating the bitumen layer.

Advantages:

• durability
• does not require maintenance;
• fire resistance, moisture resistance, sound insulation;
• safety for humans;
• light;
• low cost;

Flaws:

• the material requires special storage before installation (rolls are installed in a vertical position and do not allow interaction with heating devices);
• no possibility of installation on flat roofs slope less than 10°;
• required Additional materials for substrate;
• the roof is not in use;
• no resistance to high ambient temperatures.

The cost per square meter is $2. Installation – $2. Service life – 50 years.

Types of material for pitched roofs

Corrugated sheet

Installation does not require a solid base, which is made in the form of a sheathing made of profiled pipe or wooden slats. Installation is allowed on slopes greater than 10°. The sheets are installed overlapping and secured with screws with seals. With a slope of up to 20°, the joint is filled with sealants.

Advantages:

• ease of installation;
• high bending strength;
• durability;

Flaws:

• Soundproofing required.

Price per meter square cover– 3-6$. Service life – 50 years.

Buy the highest quality Bulat corrugated sheeting, which has a 25-year guarantee.

Sandwich panels

This is a multi-layer material. The design consists of 3 layers: 2 outer layers - profiled sheet, inner layer - polymer insulation (foam plastic). The layers are connected to each other using glue or the cavity is filled with hot foamed polymer. The finished structure forms a monolithic rigid material.

The sandwich has low thermal conductivity and high strength characteristics and does not require the preparation of a special frame. The service life of the material reaches 30 years. The price per square meter is $25 and varies depending on the thickness of the material. Installation cost – $3.

Seamless sheet metal roofing

Suitable for pitched roofs. The material consists of flat sheets of metal that are fastened together by folding (a lock formed by a special bend). Folds can be single or double. Standing seams are formed along the roof slope, and recumbent ones are formed across them. Roofs are made of ordinary sheet steel, galvanized or steel coated with polymer protection. Copper and aluminum sheets are rarely used.

Seam roofing is suitable for roofs with a slope greater than 14°. It is laid on a wooden sheathing, on which an anti-condensation coating is installed. Install the sheets in 2 stages. The stripes (patterns) are formed first equal to length stingray Then the paintings are lifted to the roof, where they are connected to each other by the side edges. Folding is performed with a special tool.

Of steel

Advantages:

• fire resistance;
• unimpeded water flow;
• flexibility of the material to cover roofs of non-standard geometric shapes;
• does not load the roof;
• frost-resistant.

Flaws:

• the roof requires additional insulation;
• easily deformed under mechanical stress;
• labor-intensive installation is carried out by professional installers;
• sound insulation required;
• accumulates a static electric charge.

The service life of a seam roof is 25 years. Price without installation cost – $6.

Copper and aluminum

Unlike sheet steel roofing, non-ferrous metal roofing is not subject to corrosion. The installation method is identical to the installation described above. The benefits include:

• aesthetic appearance;
• resistance to aggressive environments;

The disadvantage is the price, which for copper is $40 per square meter, and for aluminum – $25. The service life of copper sheets is 100 years, aluminum - 80.

Metal tiles - popularity deserved by durability and beauty

Externally, the material is practically no different from natural tiles, but has a wide range of colors. Metal tiles are produced by cold rolling steel sheets thickness 0.4 - 0.5 mm. The sheets are galvanized and coated with polymer protection. On quality products Additionally, a layer of aluminum coating, primer and others are applied.

The material is applied to roofs with a slope above 15°. The sheets are attached to the sheathing using screws (self-tapping screws) with rubber seals. The shape of the sheets allows for overlapping installation. For slopes with a slope of up to 20°, the joints are insulated with sealants.

Advantages:

• ease of installation and quick installation;
• aesthetic appearance;
• durability;
• wide range of applications;
• lightweight design (up to 5 kg per square meter);
• no special storage required and easy to transport.

Flaws:

• it is necessary to additionally install a sound-absorbing layer;
• Due to the need to combine the pattern, a significant percentage of waste is generated when cutting sheets.

The service life of the coating is guaranteed for 25 years. The price of the material starts from $4. You can do the installation yourself.

Composite metal tiles

Produced by forming on sheet metal relief, the surface of which consists of stone chips (granulate). The material is not widely available.

Advantages:

• high anti-corrosion resistance;
• strength and noiselessness;
• aesthetic appeal due to the choice of natural colors;
• durability.

Flaws:

• installation is carried out by workers with professional skills;
• special sheet fastening.

The product has a 50-year warranty without repair work. The price of the roof including installation is $70-200 depending on the roof configuration.

Traditional tiles

The technology for producing tiles has remained virtually unchanged for centuries. The material is made by high-temperature firing of clay. Some types are coated with a ceramic glaze to increase durability and provide a variety of colors. The roof is mounted from tiles measuring 30x30 cm, having a wave-like shape. The tiles are overlapped together using a lock.

Roof requirements:

• slope from 25 to 60°;
• reinforced rafter structure;
• additional layer of waterproofing.

The tiles are attached to the sheathing with screws or nails through special holes in the tiles.

Advantages:

• Sound insulation prevents penetration into the room extraneous sounds, for example, noise from rain;
• fire resistance and frost resistance;
• does not require a vapor barrier;
• beautiful material colors and design options;

Flaws:

• heavy weight;
• fragility;
• complexity of installation on roofs with non-standard architectural solutions;
• the need for annual cleaning of gutters.

The durability of the product is amazing, which is 150 years. The price per square meter ranges from $20 to $40. Installation is labor intensive.

Cement-sand

A modern type of tile tile, which is obtained by pressing a sand-cement mixture under pressure. The addition of dyes to the solution makes this material look like clay tiles. The requirements for roof construction are similar. The weight per square meter of the product is about 35 kg.

Cement-sand tiles are resistant to sun exposure, aggressive environments And low temperatures. Compared to ceramic products this material is thicker and more fragile. Cement-sand tiles difficult to transport. Losses are up to 10%.

Manufacturers guarantee the performance of the roof for 30 years. The price of the product is $15 per square meter.

Slate

The material is made from cement (85%) and asbestos. The product has the shape wavy leaf, the weight of which varies from 10 to 16 kg, depending on geometric parameters(thickness, width and length). They produce 6,7 and 8 wave sheets.

Installation can be done on roofs with a slope of 10 to 60° per lathing. The base is insulated with roofing felt. The sheets are laid overlapping. The slate is fastened with special nails with a wide head. The nail is driven into the upper wave.

Advantages:

• the material is durable under dynamic loads (impacts) and bending;
• Can be cut as usual grinder with cutting disc;
• slate is not subject to combustion, but, when exposed to open fire, “shoots” and cracks;
• easy to install.

Flaws:

• toxic due to asbestos content;
• fragile;
• hygroscopic;
• susceptible to the influence of biological microorganisms (moss forms over time).

Slate can be used for up to 40 years. The price of the material does not exceed $3 per square meter.

Bituminous shingles

The manufacturing principle is the same as that of roofing felt or roll guided material. The roll is divided into sheets from which tiles of various sizes are cut geometric shape. On back side a strip of bitumen-polymer glue is applied to the product.

The installation method and appearance of the roof imitate traditional tiles. The tiles are attached to each other using glue. Installation requires a solid sheathing (plywood, chipboard, etc.) and an inclination angle of over 10°. For slopes up to 20°, the manufacturer recommends installing an additional layer of rolled materials.

Advantages:

• the flexibility of the product allows you to cover roofs of any configuration;
• does not corrode due to condensation;
• installation is carried out on a solid base, which provides good sound insulation;
• ease of installation.

Flaws:

• exposure to low temperatures leads to fragility of the product;
• the bitumen component melts at high ambient temperatures, releasing a specific odor;
• the material is flammable.

Roofing warranty – 60 years. average price – 7$.

Bituminous slate

The shape of bitumen slate (ondulin, euroslate, aqualin) resembles traditional slate. It is made from cellulose fibers, which are impregnated with polymer-modified bitumen. Upper layer slate is painted with several layers of heat-resistant paint. Produced in sheets with a wave height of 3.6 cm, size 2x0.96 m.

Mounted on pitched roofs with a slope of more than 6° on a continuous sheathing. For a slope of more than 10°, install the sheathing in increments of 45-60 cm. The sheets are laid in an overlapping manner. Fastening is carried out using screws screwed into top part waves.

Advantages:

• large range of colors;
• waterproof;
• non-toxic;
• withstands loads of up to 1000 kg per square meter of surface;
• the material is easy to install and transport;
• does not load rafters and ceilings due to its low weight;
• cut with a regular hacksaw;
• creates sound insulation;
• durable.

Flaws:

• ignites at a temperature of 110°C;
• there is no guarantee that the color of the coating will be preserved during operation;
• ondulin is susceptible to moss formation in dimly lit areas;
• deforms under mechanical stress in hot weather;
• when heated, it evaporates bitumen substances.

The price of Euro slate is $2.5 per sq.m. Service life with normal installation is 40 years. Easy to install on your own.

Keramoplast

It's technologically advanced composite material from plastic elements and organics. Produced in the form wave sheets, dyed in mass. Installation is identical to installing slate or ondulin.

Advantages:

• safety for humans and the environment;
• soundproof;
• rigidity;
• ease of installation and cutting;
• translucent option - allows you to cover roofs with natural light.

Flaws:

• fragility and instability to mechanical stress;
• the shape of the material is unstable to temperature changes;
• difficult to transport.

The price of the product excluding the cost of installation work is $8. Service life – 10 years.

Decorative and natural materials for roofing

Slate

This natural stone, which is manually shaped for roofing. Installation is carried out by joining the tiles overlapping using locks (grooves). Lathing is required for installation. The disadvantage is the large weight, reaching 25 kg per square meter, and the price. The service life of the roof is 100 years.

Straw and reeds

Plant stems – popular natural material for covering luxury buildings. For roofing, heather, reeds, reeds and any plants with long hollow stems are used. For example, a reed covering is created in a layer of 30 cm, the dry weight of which reaches 40 kg. The roof angle must be at least 45°.

The service life of a plant roof reaches 50 years. Price including installation work– $100 per square meter.

Tree

Wooden roofs treated with modern chemicals last up to 50 years. The material is not subject to cracking, rotting and delamination. Does not promote reproduction biological species. Plank, chip and shingle types are common. The material prepared for installation is expensive. Price 1 sq.m. – $50, and the installation cost is $200.
