A garage is a room, of course, not intended for housing, but it cannot perform all its functions if the roof constantly leaks. Car owners especially often encounter this phenomenon in spring period when the snow accumulated on the roof begins to melt. But a well-made roof will not leak or cause problems, and your car home will always be dry and cozy. What is the best way to cover the garage roof to avoid all the troubles?

The purpose of any garage is protection from the external influences of a vehicle. Rain, snow, and wind can quickly ruin the appearance of a car, and for a motorcycle standing on the street, such effects are simply disastrous. Due to excess moisture, corrosion processes on metal products begin to pass quite quickly, destroying the metal. That is why the garage must be of high quality and have no leaks.

The roof on the garage can be single-pitch or gable. These are the most common options. In the first case, it is easiest to make a roof - it consists of one slope, resting on the walls of the building with different heights. The angle of inclination can be different (up to 60 degrees) - usually this indicator depends on the climate in the region, the wind rose, the selected roofing.

On a note! A roof with one slope is usually constructed if there is no need to create an attic.

The roofing material is laid on wooden rafters. The height of the difference is calculated using the formula H = D x tan a, where D is the width of the garage. The last indicator is selected according to the Bradis table. Wood for rafters must be treated with antiseptic compounds that will protect the material from the effects of biological organisms, and it is also recommended to coat it with compounds that reduce the likelihood of fire (fire retardants). Go to category pitched roof This also includes the roof, which is often found on garages built of concrete.

A gable roof is built if the garage is planned to be equipped with an attic. Typically, such a roof has the shape of a triangle. The frame consists of rafter legs connected at a certain angle, supported by the walls and at the top point of their connection. The height of the roof ridge H and the length of the rafters C can be determined using the formulas N = 0.5 x N (Z:2) And C = 0.5 x N/sin (Z:2), where Z is the slope value. For an equilateral roof, the appropriate option is to use the Pythagorean theorem.

Less often, but still, a multi-slope roof is installed. However, it is already much more difficult to implement, so rarely does anyone undertake to build it with their own hands.

Advice! To create a roof on a garage with your own hands, beginners are advised to opt for a simple pitched roof.

Comparison of materials

You can use any roofing materials for the garage roof. Of course, most owners want to save on construction by choosing a material that is suitable in both quality and cost. Let's look at the main types of coatings used for roofing.

Ceramic tiles

This is one of the most beautiful and popular types of roofing material. It is made from clay and therefore has such advantages as resistance to rust, sunlight, low temperatures and attack by microorganisms. The service life of the coating is long and amounts to about 100 years. Disadvantages include the significant weight of the material, difficulty in transportation due to fragility, and fairly high cost.

Installation of such a roof is easy, but if the roof slope angle is more than 12 degrees, you should not use tiles. It is also not suitable for finishing a concrete garage.

Prices for different types of tiles

Roof tiles

Ondulin

This is peculiar soft version slate, otherwise called euroslate. It has several color variations, which allows you to choose it to suit any building style. The service life of the coating is 20 years (warranty period), the material protects the roof well from leaks, is not dangerous from an environmental point of view, is easy to install and is lightweight. The advantages include its low price. The disadvantages include the flammability of the coating, but it will never catch fire on its own. It also fades quickly in the sun and loses its color brightness.

Prices for various types of ondulin

One of the oldest roofing options. It is a corrugated sheet made from an asbestos-cement mixture. The material is durable, easy to repair, does not rust, is cheap, and does not burn. However, it is quite fragile, and if the roof is not properly sealed, leaks can form.

On a note! Slate is one of the cheapest coating options, which is why it is often used to finish the roof of a budget garage.

Prices for different types of slate

Metal corrugated sheeting

A roofing option that replaced slate. It is made of galvanized thin steel sheet, has waves or trapezoidal corrugations, due to which it acquires additional strength.

The material is easy to install, has a lot of color variations, and lasts a long time if installed correctly. Due to the polymer protective coating, it is not afraid of rust and does not fade. The main disadvantage of the material is that if the polymer layer is damaged, the sheet will quickly rust. Moreover, the coating can be damaged just by walking on it in rough shoes. It costs more than regular slate.

An option that is quite often used for finishing pitched roofs and flat roofs. It is a rolled material consisting of thick cardboard impregnated with bitumen and covered with a protective coating. It is very cheap, durable, well insulates the roof from water, and easy to use. However, the material easily catches fire, breaks, and looks, to put it mildly, ugly. Can be used as a waterproofing layer in roof construction.

Polycarbonate

Yes, you can also use this material to make a garage roof or create a small carport. Polycarbonate can be structured or monolithic. The latter resembles glass and is completely transparent. Suitable for creating flat version roofs.

The first version of polycarbonate is known as cellular or cellular. Very light, quite durable and flexible.

Roofing process

Decorating a garage roof can consist of several stages, depending on what kind of roof is needed. For example, it can be built from scratch and for this you will have to build a rafter system, lay waterproofing, and install a covering. If you don’t need to make an insulating layer, the work will be significantly simplified. Also, the roof may already be ready (for example, concrete), but needs additional finishing.

Important! When choosing a material, it is worth considering the angle of inclination of the roof. For roofing felt, the optimal option is an angle of up to 5 degrees, for slate - no more than 25-35, corrugated sheeting is laid on a roof with a slope of up to 8 degrees, and metal tiles can be used on a slope of up to 30 degrees.

All work should be carried out only in sunny weather. It is best to check the forecast for at least a week and choose warm days.

Concrete roof finishing

Even if the garage already has a concrete roof, it must undergo special preparation before the new roofing material is installed. In general, the process begins from this stage and ends with laying a new coating.

Preparation

Step 1. The old coating from the concrete slab, if any, will have to be completely removed. This is done using improvised means - for example, a shovel, chisel, etc.

Step 2. Concrete surface is inspected - its condition must be good before further finishing. It is tapped with a hammer - everything that peels off during the process must be removed.

Step 3. All small cracks are sealed with cement laitance (or liquid glass), which is applied with a regular wide brush. Wide cracks can be sealed with polyurethane foam, the excess of which is then cut off with a sharp knife.

Step 4. Uneven base is leveled cement mortar. It is applied to the surface and leveled using a rule. Next, the cement layer is dried.

Step 5. After drying, the cemented surface is treated with deeply penetrating primer. It is applied with a roller or sprayer in an even layer.

Step 6. When the primer layer dries, the surface is covered bitumen mastic.

Roofing work on a concrete roof

Step 1. Work on laying roofing felt on the roof begins with lifting rolls of material onto the roof surface. Next, one of the rolls is placed in the corner of the roof and the bitumen mastic applied to the base is heated using a gas burner.

Step 2. A roll of roofing felt without sprinkling is carefully unrolled using a metal hook as the mastic heats up. The burner flame is also directed to the lower part of the rolled material. In this way, the entire roof is covered, individual strips of material are laid overlapping each other.

Step 3. The top layer of material is laid, which already has powder on the surface. To begin with, the required dimensions of the segments are measured. For ease of use, they are rolled into rolls.

Step 4. The top layer of material should be laid on top of the bottom one so that the seams overlap each other, that is, offset. Laying begins from the bottom point of the roof slope.

Step 5. And it's in motion again gas-burner. The previously laid lower layer of material is heated.

Step 6. After bottom layer will be well warmed up, heating and rolling out of the roll with sprinkles begins. Rolling is also done using a hook.

The same metal hook is used

Step 7 The material laid in this way is sprayed with water to speed up the cooling process. Also, a layer of water will prevent crumbs on the coating surface from sticking to your hands and tools.

Step 8 The material is pressed to the roof surface using patting movements using a wooden board wrapped in fabric.

Step 9 The entire roof is closed in the same way. The individual strips of coating are laid overlapping.

Step 10 The sides of the roof are also covered with roofing felt.

The process of finishing a garage roof with corrugated sheets

Quite often, corrugated sheeting is used as a roofing covering when constructing a garage. This strong and durable material will serve faithfully if it is installed correctly.

Preparation

Step 1. The roof is being prepared - if necessary, a waterproofing layer is laid. Next, the installation of supports for the material begins - 50x50 mm bars are laid on the base, and 40x15 mm boards are placed across them.

Step 2. The bars are leveled strictly, and the crossbar boards are also leveled.

Step 3. The longitudinal bars are attached to the base of the roof using frame bolts.

Step 4. The transverse boards are fixed with self-tapping screws to the bars - two pieces at the edges, and one at a time in the middle of the boards.

Step 5. Planks are nailed along the perimeter of a kind of sheathing. Their top part should be flush with the crossbar boards. You can start laying corrugated board.

Installation of corrugated sheets

Step 1. Sheets of corrugated sheets are lifted onto the roof, laid on the sheathing and leveled. Separate sheets are laid overlapping in 2 waves. To install the roof, it is better to use sheets of such a size that you can cover the roof slope from edge to edge at once.

Step 2. Where the garage pipe exits, it is necessary to trim the material so that a hole is formed for the chimney. The easiest way is to cut a hole in the whole sheet, and then put the sheet on the pipe.

Step 3. The corrugated sheets will be screwed on with self-tapping screws. For convenience, you can apply markings along a string stretched evenly from one edge of the roof to the other. The markings are applied with a marker. The markings should be located directly along the crossbar boards.

Step 4. Special roofing screws with a rubber washer-gasket are screwed in. Along the perimeter of the sheets, their pitch is 40-50 cm, and along the rest of the sheet, according to the markings, they are screwed through one corrugation.

Step 5. The side part of the roof can be finished with roofing felt reinforced with bitumen mastic, or covered with metal panels of the required height.

Step 6. The panels are fixed using roofing screws, and the joints between them and the roof are covered with bitumen mastic.

Step 7 Fabric strips are glued onto the first bitumen layer, which are then coated with bitumen again.

Step 8 The joint between the pipe and the corrugated sheet is sealed with waterproofing material or sealant.

What material should I use for the garage roof? Here the owner himself will have to decide in accordance with his wishes and budget. It is also important to consider the features of each coating. But of the two main materials listed above, it is better to use corrugated sheeting - it will be more reliable and durable for the roof than roofing felt.

A roof of any type is responsible for the safety of the building, the integrity of the walls and the interior decoration of the building. It protects the house from scorching heat in summer, from snowfalls in winter, heavy rains in the off-season, and also performs not the least function in shaping the overall exterior of the building. Unlike sloping, multi-level, hip and other modifications, a pitched roof is reliable, economical and least expensive. This type is often used for outbuildings, verandas and garages. Despite its simplicity, the roof is made according to calculations and building codes in compliance with the rules and technologies for laying roofing material.

Advantages and disadvantages of a pitched roof

A pitched roof, like any medal, has two sides: it has its advantages and disadvantages. The construction of a roof of this type is characterized by simplicity and low cost, since you can install it yourself, without resorting to the services of construction team and saving a certain amount on this.

A garage with a pitched roof will reliably protect the car from snow and rain

So, pay attention to the main advantages:

• the design is based on right triangle- the “lightest” geometric figure, knowing the length of its sides, you can easily calculate the angle between them (in our case, this determines the angle of inclination of the slope);
• installation of a pitched roof is intuitively simple and clear;
• It will take several days to cover a typical “one-pitch” roof; with certain skills and dexterity, such a roof can be laid even over a weekend.

In addition, design problems fade into the background and give way to solidity and reliability. It is imperative to consider in what area the garage will be built and how much precipitation will fall on the roof. Now the disadvantages:

• An insufficiently strong rafter system will not be able to cope with a large mass of snow without problems. That is why in regions with harsh winters it is preferable to use a gable roof;
• the second disadvantage will be the lack of a fully functional attic space, which significantly limits the ability to use additional space for temporarily unused materials or tools;
• the actual absence of an under-roof zone significantly complicates or almost completely negates the installation of high-quality thermal insulation. It is hardly possible to insulate a roof whose slope angle is 9° - 12°.

Calculation of the slope of a pitched roof depending on the choice of roofing material

If preference is given single-pitch design, pay attention to the selection of roofing material. The angle of inclination of the roof will depend on this, which, in turn, is necessary for the smooth descent of snow, rain, and ice from the slope:

• for roll, bitumen, polymer materials The slope of the slope should not exceed 10 degrees. The minimum safe tilt is at least 6°;
• for flat or corrugated slate, sheet iron with a seam joint, the maximum permissible angle of inclination is 20 o;
• if you use corrugated sheeting, tiles, asbestos-cement and slate slabs, metal tiles as roofing, you should not exceed the maximum permissible 25–30 o.

The angle of inclination of the slope will depend on the choice of type of roofing material

Shed roof design with drawings

When building a pitched roof, pay attention to the design of the rafter system and the selection of roofing material - safety of operation and the ability to cope with loads depend on this. In rare cases, reinforced concrete slabs are used (provided that the angle of inclination is minimal). But mostly they use a rafter base made of wooden beams.

For correct calculation you need to know several parameters:

• the length and width of the load-bearing walls of the building;
• angle of inclination and desired length of the slope;
• the type of material with which the roof is covered.

Based on the dimensions, it will become clear whether additional support posts are needed to strengthen the rafters. The angle of inclination will determine the need for additional construction of the pediment and its height, as well as whether it is necessary to do attic floor. According to fire safety standards, it is prohibited to install an attic with a height below 1.6 m.

The roof truss system is calculated depending on the width of the slope

It is extremely important to determine the angle of inclination of the garage roof at the design stage, since the height of the opposite sides of the box and the feasibility of using a cantilever frame on one of the sides to maintain the required slope will depend on this.

Use the wood only after it is thoroughly dry. Lumber for rafters should not have chips or other defects at the joints. For long rafters, use laminated veneer lumber. Boards are used only for light roofing surfaces.

Mauerlat - a reliable basis for a pitched roof

The rafter frame is a structure made of boards or logs laid parallel, resting on the base of opposite walls of different heights. The Mauerlat performs a transitional function from the walls to the roof and is a connecting link. If the garage walls are made of wood, which is unlikely in the age of new construction technologies, there is no need for it. Brick (silicate and ceramic) is also a strong and durable building material in itself, so there is no need to lay a mauerlat on walls one brick thick. This will only add financial problems and extra costs workforce. In the case of a pitched roof, the rafter system can be installed directly on the frame - this justifies itself when the slope is minimal and the covering is not heavy. Installation of a tiled, asbestos-cement or slate roof requires the presence of a Mauerlat. It helps to evenly distribute the wall load along the entire perimeter of the building. You cannot do without a Mauerlat if the walls are made of gas silicate blocks or foam concrete. This material is too fragile and loose - an anchor bolt or dowel is unlikely to hold in it.

How to fix the Mauerlat on the walls of the garage

The Mauerlat is laid on two opposite walls, on which the rafters will subsequently rest. So:

1. Place any waterproofing material. This can be roofing felt or bitumen tape.
2. Place the Mauerlat on top. To do this, use timber measuring 50*150 mm or 100*150 mm, depending on the thickness of the walls of the building.
3. With help anchor bolts or dowels secure the tree to the base.

This uniform redistribution of the load is especially important for walls made of blocks, since they have less strength than, for example, brick.

In some cases, reinforcement backfills are used to secure the rafter system to the walls during forcing. Using steel wire, rafters are tied to the reinforcement; traces of the strapping are hidden under the finishing of the walls inside the garage.

Reinforcement bookmarks are used to secure rafters

Sometimes it is necessary to install a reinforced belt: special studs or cuttings of reinforced pipes are inserted into the upper masonry of the wall, onto which the Mauerlat beam is placed. In addition to additional redistribution of the load, such a belt will allow you to maximally adjust and fix the horizontal level.

Technology for constructing a pitched garage roof

Before you start construction work, you need to do some trigonometric calculations. With their help, the difference in heights of opposite walls is found, the angle of inclination and the area of ​​​​the future roof are calculated. Most calculations can be done independently, using school formulas familiar to everyone for finding the area, length and other parameters of different figures. The amount of required building materials depends on the calculations and, accordingly, the budget required to implement the idea is calculated.

The amount of required building materials depends on the calculations and the budget required to implement the idea is calculated.

Having done necessary calculations and having purchased the material, you can begin building the garage roof.

How to make a roof from a profiled sheet with your own hands

Let's look at an example of a shed roof made of corrugated sheets. Strength, lightness and rigidity make it stand out among modern building materials. Profiled sheets are made from galvanized steel sheets using the cold rolling method. For greater rigidity, it is subjected to profiling during production, due to which ribs of a wave-like or trapezoidal shape can be seen on the sheets. It is available in different thicknesses and corresponding markings. The most suitable profiled sheet for roofing is NS44 or NS35.

A corrugated roof will reliably protect your car

To install the roof we will need:

• wooden boards of appropriate length and timber for the Mauerlat;
• roofing material (in our case corrugated sheeting) covering the entire roof area, taking into account overlaps;
• tools for woodworking: axe, circular saw, hammer, plane, jointer, screwdriver;
• tools for working with metal: grinder, rubber hammer, awl;
• fastening materials: stapler with staples, nails, self-tapping screws or roofing screws with rubber gaskets;
• measuring and marking tools: tape measure, ruler, level, pencil, chalk.

After the garage frame has been raised to a sufficient multi-level height, we begin building the roof:

1. We proceed to the installation of the Mauerlat (the installation technology is described above).
2. We build a rafter system and lay the sheathing.
3. We lay the first rafter on the mauerlat, extending 40–50 cm beyond the overhang limits, make a notch on it for fixing and use it as a template for subsequent boards.
4. With help metal corners, self-tapping screws and a screwdriver, we fasten the rafter boards over the entire roof area at equal distances.

   The rafters are laid on the mauerlat at equal distances

5. We make the sheathing from the bottom up.

   We lay the sheathing on the rafter system

6. We lay roofing material or bitumen tape under the overhangs for waterproofing (if exterior decoration The garage can be sheathed with siding or the same profiled sheet).
7. With help construction stapler We install a waterproofing film or a vapor-proof membrane, and place a counter-lattice on top.

   A counter-lattice is attached over the waterproofing

   8. We lay the sheets from left to right, starting from the bottom row, with an overlap of 2 waves. If the height of the corrugation is no more than 2 cm, we attach a self-tapping screw to the top of the rib. If it is higher than 2 cm, we attach it to the base. The gaskets under the screws should not dangle, but they should not be pinched either - this will lead to subsequent roof leaks.

   The procedure for laying corrugated sheets on the sheathing

When the roof is ready, the final necessary step remains - installing a drainage system. The absence of ebb tides will eventually lead to wear and tear of the foundation, damage to the base and façade.

Low tides will protect the garage from destruction of the foundation and plinth

If all instructions for installing a pitched garage roof have been followed, you will receive a dry and reliable protection for your favorite car. A durable roof will protect the room from leaks and destruction. You can do it yourself, but together with a partner it will be faster, more reliable and more fun. The more valuable such a building will be.

Car enthusiasts with extensive experience know very well that a perfectly made roof for a garage is very important, since it is not only the final stage of the entire construction, but also serves as protection from various atmospheric precipitations. Installing a roof is a complex process, so you must first become familiar with what kind of roofs are made on garages and choose the right roofing covering.

What types of garage roofs are there?

The roof for a garage can be varied, so you must initially decide on its design. In many cases, it is possible to replace one type of roof with another, but this involves additional expense and worry. That's why it's better to initial stage roof construction done right choice.

Before choosing one of the types of roof frames, you should decide on its load-bearing characteristics, the size and shape of the box, and then consider one of the presented roof design options.

Features of a pitched roof device

A pitched roof is the simplest type of structure, which is in great demand today, since it has no analogues of similar cost. To equip such a roof, you do not need to use special building materials, special equipment or have deep knowledge in the field of design.

A shed roof is the simplest and cheapest structure for covering a garage.

Features of the construction of a pitched roof are as follows:

Two boards connected along the wide side are often used as rafter legs, but the best option is to use beams made of metal or wood with a cross-section of 50*150 mm.

A pitched roof consists of the following parts:

• the base of the roof is the rafter system to which all other constituent elements are attached;
• sheathing is a support for the roof covering;
• elements that strengthen the rafter system;
• insulating materials, which protect the structure from water and retain heat inside the structure;
• directly covering the garage roof.

The upper ends of the garage with a pitched roof must have a mauerlat or logs that support the rafters. They are attached to the walls using wire anchors. The anchors themselves can be embedded in the masonry or driven into the wall.

Such a structure can be covered with any type of roofing material: roofing felt, corrugated sheeting, soft tiles, etc.

How is a gable roof constructed?

A gable roof is installed over the garage if an attic is needed. The most common gable roof gable design is an isosceles triangle.

Rafter system gable roof can be performed in the following options:

Installing a gable roof is very simple, since its base consists of several rafters of identical sizes. The installation of the frame rafters is done sequentially, and then they are connected at the very top of the roof.

The roof support is the walls of the building. To correctly calculate the size of the ridge and rafters, you need to know not only the angle of inclination of the roof, but also the dimensions of the building. To accurately make a canopy, you need to add about half a meter to the length of the rafters.

Installation of a gable roof begins with the arrangement of trusses, which are assembled on the ground according to a template. The Mauerlat is installed around the perimeter of the building, and then it is attached to the wall using anchors. A layer of roofing felt is made between the Mauerlat and the wall.

Characteristic features of a sloping roof

A broken roof is a structure with numerous broken lines. In principle, this is a type of gable roof that allows you to create an additional room on the attic floor.

There are the following types of broken roofs:

The reliability of the structure and its comfort depend on the type of roof chosen. However, sloping hipped roofs are becoming most popular today, since they ideally combine two features: the effective use of additional space and the low complexity of installing the rafter system. This approach involves obtaining full-fledged living quarters with small financial investments.

The installation of a sloping hipped roof of the garage allows you to create full-fledged living quarters on the second floor

To build broken roof, it is necessary to make a fairly dimensional structure of the rafter system, however, during its construction, modular installation methods can be used, so it is not necessary to use different lifting equipment. The rafter system and racks are cut at the desired angle in those places where there are fractures in the slopes. To secure the nodes, you need to use “kerchiefs” made of plywood with maximum thickness 2 cm.

This design hipped roof perfect for garages small sizes, where it is not possible to construct a broken roof of a more complex shape. For buildings with large areas install another rafter system.

Used garage roof

An operable roof is a flat-shaped structure that has a special coating. A similar structure can be built over the entire area of ​​the building or over some part of it.

The roof in use is conventionally divided into the following types:

The construction of such a roof must comply with the standards specified in SNiP, since the operating time of the roof depends on the correctness of the selected materials, the calculations performed, and the consideration of loads.

Typically, the roof structure has a multi-layer structure, and it is done in this way:

• rigid base;
• mandatory vapor barrier layer;
• insulation;
• screed at the correct angle;
• waterproofing layer;
• protective separator;
• finishing coating.

An existing roof can also be constructed using granite gravel (fraction 25/32 mm), which is laid on geotextiles. In order for the roof to operate normally, gravel is laid with a thickness of at least 50 mm. Geotextiles in parallel with gravel will make the coating more stable.

The undeniable advantages of a sliding roof for a garage

Today, mobile sliding roofs, which have many advantages over traditional roofs, are of great interest.

According to its design, a sliding roof can be of the following type:

By functionality Sliding roofs are divided into:

• seasonal (the structure moves only during a certain period, usually in summer);
• permanent (used throughout the year);
• temporary (used for mobile light structures).

In addition, a sliding roof can be not only permanent, when the entire structure or a specific part of it is covered, but also attached over various buildings to the main house. Among other things, a retractable roof can also be designed over other free-standing buildings, for example, greenhouses, greenhouses or observatories.

The main elements of a sliding roof are load-bearing aluminum profiles, which are manufactured with a variety of protective coatings in the form of:

• anodizing;
• powder paint;
• various enamels.

To give rigidity to the profiles, a steel pipe with a square cross-section is installed inside them. However, these forms of frames are considered the most durable sliding roofs, How:

• dome;
• arched;
• single-pitched with a slope angle of at least 45 o.

For other types of roofs, which have a slope angle of up to 45 o, only reinforced coverings and profiles are used.

The highest quality and effective options When installing a retractable roof, coverings made of plexiglass, triplex or tempered glass. This type of panel can withstand hail up to 14 mm.

What types of materials are used for garage roofs?

A garage roof can be built from a variety of building materials, and their cost depends on the “thickness” of your wallet, and installation methods depend on the time you have. Therefore, it is worth thinking carefully about the type of roofing material for the garage.

A fairly popular and well-known material among consumers, which is affordable and easy to use. One roll is enough to cover 10 m2 of roofing and forget about it for 15 years. The main advantage of roofing felt is that this coating is inexpensive and durable, but for its use it is necessary to make a sheathing, as well as a rigid frame.

Ruberoid is one of the most inexpensive and popular materials for covering garage roofing

Waterproofing is considered high-quality, provided that it is made of at least four different layers, and different types of roofing material are used.

Corrugated sheet

This is a modern material that is replacing slate, since the service life of corrugated sheets exceeds half a century. When deciding how to cover your garage roof, consider purchasing load-bearing wall material of the NS brand. The wavy profile of the sheet is made using cold rolling. All types of corrugated sheets have an identical wavy trapezoidal shape, but the size and height of the material differs for all brands.

Corrugated sheeting is one of the most popular materials for garage roofing because it is lightweight and lasts at least 50 years

Corrugated sheeting is a durable, fireproof, as well as water and soundproof roofing material that meets government standards. Its advantage is its reusability.

Slate

Traditional slate is often used for garage roofing, as its service life is about 40 years at a moderate cost. The material is an asbestos-cement board, which is quite simple to install - holes are drilled into which galvanized nails are driven with an allowance of a couple of millimeters. Further, the installation of this material is carried out identically to the installation of a roof made of corrugated sheets with the only difference - the corners of the internal spans are cut off.

Slate is laid on the garage roof in the same way as corrugated sheeting and secured with special slate nails

Roof tiles

The garage roof can also be made of cement-sand or ceramic tiles. These types of natural coatings last approximately 100 years and are characterized by resistance to ultraviolet radiation, fire resistance and the ability to withstand a variety of temperature changes. In addition, the tiles perfectly absorb noise, do not retain static voltage and have low thermal conductivity.

To lay tiles on a gable roof, special locks are used on each product

If a roof is being built with a slope of about 12 degrees, then metal tiles are the ideal option. The flooring is made of galvanized steel 0.6 mm thick, which is coated with a polymer composition. To give the material its shape, it is stamped. Metal tiles are sold in a varied palette of colors.

Metal tiles are laid in large sheets, often corresponding in length to the dimensions of the slope

Seam roof

Metal is the lightest building material, allowing you to save money when installing the frame. Of course, when maintaining a metal structure, you will have to spend a lot of money, but this material is suitable for any type of roof. For example, when planning to build a metal roof, when arranging it, you can only get by with sheathing, which is made of beams.

To create a seam garage roof, use special tools, forming the sheet fastening profile

Installing a seam structure requires the use of special equipment and the involvement of professionals, since even minor “punctures” in the calculations will lead to distortions, which are much more difficult to eliminate than to immediately build a roof correctly.

How and how to insulate a garage roof

Every motorist dreams of a warm garage, and making the roof insulated is quite simple.

In modern construction, the garage roof is insulated in combination, that is, traditional insulation is combined with a heat insulator that reflects light and does not allow infrared radiation to pass through. However, in some cases such costs may be unreasonably high, for example, if the building is detached. Then use classic materials, such as:

1. Mineral wool. She has wonderful technical characteristics. It is used only with hydro- and vapor barrier material, which protects mineral wool from water. In addition, mineral wool is quite affordable.

   
   Mineral wool is inserted into the cells between the rafters and secured with wire or fishing line before the final ceiling covering is laid

2. Glass wool. This material is cheaper than other insulation materials, but has a low degree of fire resistance. If you plan to make a pitched roof, then it is better to buy a special type of glass wool, which has a high density structure. This material is produced in rolls with a width equal to the normal distance between the rafter legs.

   
   Glass wool is one of the most inexpensive and available materials for roof insulation

3. Styrofoam. This is a waterproof material, which in its thermal insulation characteristics is similar to mineral wool. Polystyrene foam is a flammable insulation material, but the PBS-S brand with the addition of fire retardants has the property of self-extinguishing. Due to these features of the material, it is used as insulation for garage roofs. In addition, it does not rot, mold and mildew do not form on it.

   
   Laying foam plastic in the sheathing of a garage roof does not require special skills

4. Penoizol. It is a liquid foam, but with better performance. It is resistant to fire and water, hardens when placed in a confined space, and forms an ideal seamless coating. With all this, penoizol is cheaper than any sheet foam, and its service life is about 40 years without loss of characteristics.

   
   To insulate the roof with foam insulation, you must use special equipment for spraying

You can also use traditional options for insulating a garage roof, for example, using sawdust, but they cannot be compared with modern materials.

The garage space is an object with a high probability of fire, so it is necessary to purchase insulation with improved fire resistance characteristics.

Insulating the garage roof from the inside

Required Tools:

• special buttons or furniture stapler with staples;
• vapor barrier film;
• carpentry tools;
• self-adhesive tape;
• waterproofing;
• insulation.

Thermal insulation of the roof from the inside is carried out as follows:

Such a cake is laid not only on wooden beam structures, but also on reinforced concrete slabs. Before installation, the beams are protected with sheet material, after which waterproofing is attached to it, then insulation and vapor barrier.

Avoid contact waterproofing film with insulation, there must be a certain distance between these materials for ventilation. Direct contact is only allowed if a superdiffusion membrane has been used.

We insulate the garage roof from the outside

From the outside, the roof is insulated during the construction stage, since it is not very convenient to open a completed building in order to correct shortcomings. Please note the presence of a vapor barrier, which must be installed on the side of the room. This way you can prevent not only re-condensation of vapors, but also avoid unpleasant leaks.

How to repair a garage roof

Leaking is the main nuisance that a garage roof brings, and the reasons for this may be:

• exhaustion of the strength resource during operation;
• negative impact of weather;
• incorrect roof installation;
• mechanical damage due to careless cleaning of the roof from snow cover;
• low quality finishing material;
• neglect of the installation of waterproofing;
• violation of installation standards when using roofing material.

Leaks must be eliminated at the stage of mold or wet spots appearing. Initially, it is worth checking the joints and joints, then the integrity of the roof for holes, chips or other damage. In addition, it is necessary to eliminate various types of blockages, such as dry leaves that clog the corners of the roof and accumulate moisture.

The method of eliminating a leak depends solely on the amount of damage and the characteristics of the roofing material. Partial repairs can be carried out for small-piece and soft roofing materials. Volume repair work for panel and sheet materials depends only on the complexity of the structure and its damage.

High-quality construction garage roofs are the best option to minimize your costs if you have necessary knowledge in construction. The choice of material and tools is of great importance when arranging a roof. Just read the necessary information and you can do all the work yourself. We wish you success!

Every car enthusiast strives to equip his “iron horse” with a decent garage, which will allow him to maintain the excellent appearance of the car and significantly increase its service life. Except strong walls, a reliable floor and well-executed ventilation, it is very important to have a properly designed and high-quality garage roof. If you have the desire and knowledge of how to properly make a garage roof, then this type of work can be done independently. Let's take a closer look at the issues related to building a roof for a garage.

Requirements for a quality roof for a garage

• Reliability of the design. The roof must withstand temperature changes and atmospheric loads corresponding to your climate zone. It should be borne in mind that the heavier the ceiling, the stronger the walls must be to withstand this load.
• Good hydro and thermal insulation. To prevent precipitation from getting moisture into your car and create favorable conditions for its storage.
• Use of non-combustible materials. Garages are premises with an increased fire hazard, so it is extremely important to use non-combustible materials during their construction.
• Attractive appearance. Allows the garage to harmoniously fit into the overall appearance of the estate. Moreover, if the garage is adjacent to the house, then its roof should be made in the same style.

Main types of garage roofs

• Single slope (flat). It is the most simple view roofs for the garage. It is characterized by a small amount of required material. Most often, the slope angle is 20-30°, but if desired, the angle can be reduced to 10°, ensuring the required level of resistance of structures to precipitation. The most in a fast way The manufacture of this type of roof is the use of floor slabs, which also have low thermal conductivity and a good level of sound insulation. This option most optimally solves fire safety issues.

• Gable. For all the beauty of this design, it is more complex to manufacture and expensive. Therefore the choice this option It is produced mainly for architectural reasons or due to the need to arrange an attic space for storing various things. When building a gable roof, it is necessary to make a ceiling and insulate it. The very design of this type of roof contributes to an excellent view of it from the side, so you should not use cheap roofing materials so as not to spoil the overall impression of the building.

Types of roofing materials

When constructing garage roofs, the most common roofing materials are:

Slate. Quite a popular roofing material with a long service life (up to 40 years). It is made of lightweight asbestos cement board with a high degree of wear resistance.

Compared to corrugated sheets, slate has more weight and requires a stronger and more reliable rafter system.

The slate is laid in rows from bottom to top, followed by an overlap (about 20 cm). Fastening to the sheathing is done using special nails, and it is advisable to drill holes for them.

Ruberoid. The main advantage of rolled roofing felt is its low cost, sufficient coating strength and effective protection from water. The service life of a roof made of roofing felt correct operation reaches 15 years of age.

This roofing material is mounted on a continuous sheathing.

The first step is to prepare the base for the roof. Then, immediately before laying the first layer, it is necessary to coat the base with bitumen mastic, roll out and press the roofing material. Installation of roofing felt strips is carried out from bottom to top with an overlap of 20 cm. This installation method does not allow water to flow into the joints between the sheets. Then, in a similar way, only in a perpendicular direction, the second layer is laid. And finally, after coating with bitumen mastic, it is necessary to lay the third layer, also in a direction perpendicular to the previous layer.

Profiled sheeting. This material has gained popularity due to its long service life (up to 50 years) and low weight, which reduces the cost of constructing a rafter system and manufacturing sheathing. The corrugated sheet is made of coated steel polymer coating or a layer of zinc (galvanized steel). The characteristic trapezoidal profile is produced by cold rolling. The dimensions of the sheet and the specific shape of the profile differ for different models. The sheets are installed with an overlap of about 20 cm, from bottom to top. The sidewalls, edges and tops are decorated using special profiles.

When creating a roof based on corrugated sheets, it needs to be waterproofed and insulated.

A properly designed and manufactured garage roof will allow you to be sure that your car parked in the garage is not in danger of leaking, and it is reliably protected from the vagaries of the weather.

This is how to properly roof a garage with roofing felt:

One of important elements Any building is its roof, which is exposed to various physical and climatic influences. Its reliability and service life depend on the chosen material for its covering - the roof. The modern market offers many types of such finishing materials that can be selected for certain climatic conditions and the characteristics of the structure on which they will be used.

Peculiarities

The roof of the garage and its roofing are practically no different from others standard designs this type: they are used to protect the main building from moisture. But those found on vehicle “homes” are almost always simple. This is due to the fact that during the construction of such systems there is no need to create beautiful structures for decoration purposes. The materials usually used are the same products that are used in the construction of standard roofs for industrial or residential buildings. Very often today, instead of the usual ones, insulated mansard roofs are made, the rooms under which can be turned into small housing in the future. But such designs are relatively expensive and rare.

Materials

The installation of a roof on a garage involves the formation of a reliable protective layer that will prevent moisture from penetrating into the building. Therefore, for such purposes, in most cases, coatings from several layers are used.

The following products can be used as a top roof covering:

• Ceramic tiles. The material can be classified as environmentally friendly and durable. Among the advantages are anti-corrosion resistance, minimal destruction by microorganisms, and the ability to withstand significant temperature changes. The disadvantages include the high cost, as well as significant weight, which forces ceramic tiles to be laid only on durable frames, the slope of which does not exceed 12 degrees.

An alternative to this product today is metal tiles, which are lightweight and easy to install.

• Ondulin has proven itself well as a roofing material. A roof made from it can last more than 20 years, and it itself is practically not destroyed under the influence of external influences. negative factors. It is distinguished by its relatively light weight and low cost. This combination allows you to form a roof not only cheaply, but also quickly. The only drawback can be considered the flammability of ondulin, but if you minimize the likelihood of its ignition under the influence external factors, then it will be the best option when building a garage.

• Corrugated sheet appeared on the market for a long time, but only recently gained enormous popularity. This material is a thin sheet of metal that is given a certain shape to increase its strength. To protect steel from rapid corrosion, the upper layers of the product are coated with galvanization and polymer compounds that prevent moisture from entering the metal itself. Products of this type are lightweight, easy to install and durable. There are many of them on the market color options. Such coatings are very durable, but if the top one is damaged protective layer, then the metal begins to rust very quickly. Therefore, it is advisable to use only high-quality products from well-known manufacturers for roofing.

• Slate obtained from various shale rocks, which are pressed in special machines. This roofing material resists temperature changes well and is also not afraid of exposure to various chemicals. It does not support combustion. However, slate sheets are heavy. This, in turn, complicates installation. They are also very fragile, so it is advisable to work with them carefully and using a special tool.

• Galvanized steel sheets outwardly they are smooth sheets that are attached to the base with special screws or nails. The disadvantage can be considered high “noise” - the material makes loud sounds in strong winds and rain, as well as the likelihood of corrosion processes occurring with constant exposure to moisture.
• Soft tiles. Outwardly it resembles roofing felt, but differs more beautiful design. It is produced in the form of small parts of various sizes and shapes. The material is very durable, but requires a perfectly flat surface for installation, so you need to nail additional sheets of moisture-resistant plywood or OSB to the rafters, and then lay such tiles on them.

Waterproofing materials should also be considered.

• Ruberoid It is produced in rolls that cover roofs to prevent leaks. Please note that it can be used as an underlayment or as the main roofing material. It is used quite rarely wooden bases, since the canvas does not have design design, and is also highly flammable. At the same time, this universal product is practically indispensable for flat roofs, where it protects concrete bases.

• Bikrost. This is another type of waterproofing substance. Use it as a substrate. In many properties it resembles roofing felt.
• Bitumen or liquid rubber. Such materials are obtained from substances based on petroleum products, and are used to protect pitched concrete roofs. In molten hot form, these compositions are simply applied to the base. This leads to the formation of a uniform layer that fills all the cracks and does not allow water to penetrate into them.

Types of structures

Today, when constructing garages, you can use one of several types of roofs:

• Flat. The angle of inclination of such a plane is minimal (up to 3-5 degrees) or completely absent. Such structures in most cases are monolithic concrete floors. They are found in large industrial garages, which are built of brick or other durable material. In everyday life, a flat roof can be made of wood, but it will not be able to hold a large weight of snow for a long time in winter.

• Single-pitch. This type of roof is distinguished by the presence of one plane, which is located at a slope relative to the frame. The device of this design is the simplest. You can even build it yourself without the appropriate skills. The angle of inclination here often does not exceed 30 degrees. This is due to the fact that the width of the roof is significant and if the slope is increased, the base simply may not withstand the load.

• Gable. Roofs of this kind are the most common and practical. The systems are distinguished by their simplicity and speed of construction. The angle of such surfaces can be adjusted to 45 degrees. Please note that the slope may be different on each side of the slope. This approach allows you to give the structure the shape of an irregular triangle. The practicality of the system has been known for a long time. If you choose the right height, you can create a small attic under the roof for storing things. A variation of this design are mansard roofs. They differ in the height of the room under the roof, which allows you to place a living space here. But this option for garages, as already mentioned, is not so common.

Slope angle

Today garage buildings can have different shape and structure. It all depends on the needs of the specific owner. But during construction or renovation, it is important to choose the right roof slope.

The ability of the surface to withstand various loads, as well as the possibility of coating with various materials, depends on this parameter.

There is no universal angle for the slope of a garage roof.

It all depends on the finishing materials with which it will be covered:

• Up to 20 degrees. Such roofs are usually pitched. For such surfaces, coatings such as asbestos cement sheets are used, clay tiles, steel sheet.
• 20-30 degrees. This angle is the best option for most types of garage roofs. This slope allows snow not to linger, and also allows the use of almost all substances for finishing, from soft tiles, slate to various roll coverings. Please note that previously this factor was usually not taken into account during construction, so the rise of the structure does not always correspond to this value.

• 35 degrees or more. This angle is steep, which is not always good for roofing material. For such slopes, experts recommend using metal tiles that can withstand this load. It is not advisable to lay this material on roofs with a lower slope. Therefore, if you plan to use this finishing product, you will first have to lift the entire system if it does not meet specifications.

When choosing the angle and material for the ceiling, it is also important to consider several other factors:

• Wind power. It is important to determine the maximum wind load indicators and their direction. For this purpose, special wind maps are used, which show the percentage of wind loads throughout the year.
• Amount of precipitation. Particular attention should be paid to snow, as it can accumulate and become compacted. If there is a lot of such precipitation, then it is better to use roofs with an angle of more than 20 degrees. When it is not possible to do this, the frame of the structure should be strengthened as much as possible so that it can withstand the upcoming loads.

How to calculate the amount of materials?

Self-installation roofing very often involves the purchase of roofing materials. But before you go to the store, you should count the quantity of this product.

The algorithm for calculating material volumes can be reduced to the following sequential operations:

• Finding the angle of inclination. It is needed to calculate the surface area. This operation can be carried out using mathematical formulas. To avoid using trigonometry, the easiest way to find the width of the slope is to use the Pythagorean formula. Initially, measure the height of the ridge and the distance from the center point to the edge of the roof. In theory, you will end up with a right triangle. Having obtained the values ​​of the legs, you can find out the length of the hypotenuse. To do this, use a simple formula, where a and b are legs.

Please note that this approach can be used for both single-pitch and gable roofs.

• Once you know the width of the slope, it is easy to get the total area of ​​the entire roof. To do this, you need to measure the length of the garage along which the material will be laid. The area is calculated by multiplying the width and length by each other.

• At this stage, you need to find out the volume of finishing materials that are needed to cover a specific area. For gable roofs Calculations should be carried out separately for each half. The technology is quite simple and involves dividing the total area by the size of one roofing unit, taking into account a certain coefficient. For example, if one sheet of corrugated sheeting has an area of ​​1.1 sq. m, then to cover 10 sq. m of roof should be taken 10 whole sheets. It is important to take into account that during installation some products are slightly stacked on top of each other. The number of sheets may also depend on the width and length of the roof. Very often these numbers are not integers, so the material will have to be cut at the end. In some cases, it is possible to use leftover products for this.

It is not always possible to accurately calculate the number of roofing products. Therefore, it is better to take a little more materials when calculating. But if you know a roofer, then contact him, he will help you calculate this figure with minimum quantity waste.

Waterproofing

Excess moisture inside any room can lead to rapid destruction of all finishing materials. Therefore, when installing roofs, including garages, you should take care of high-quality waterproofing.

Today this problem is solved using several types of materials:

• Liquid formulations. This includes all bitumen-based products. They are sold in the form of liquid or solid elements, which must be brought to a liquid state before use. Mostly painted with bitumen flat roofs with a slight slope. Apply the composition using a brush or a special sprayer. In this case, all cracks are completely sealed. Such products are used mainly for concrete roofs, but theoretically they can also cover other substances. Please note that the mixtures can be used both outside and inside the building. Therefore they can be used as aids.

• Roll materials. Products of this kind are long sheets that cover the roof frame. They are located directly under the finishing material. Their classic representative is roofing felt. But today, special membrane fabrics are increasingly used for such purposes. They are attached directly to wooden logs using a stapler and staples. It is important that adjacent sheets are laid with a slight overlap. All joints are insulated using cold welding or special tape. Please note that all waterproofing sheets must form a kind of drain. Therefore, the lower ends necessarily protrude beyond the edge of the joists.

Waterproofing is an important step that must be carried out when installing a roof.

The service life of the entire structure depends on how well it is performed.

Installation subtleties

The roof finishing technology depends on the design itself and the selected material.

Let's begin our consideration with the coating of reinforced concrete floors, consisting of the following sequential actions:

• Concrete cleaning. There should be no dirt or large inclusions on the surface of the material, as cleanliness will contribute to better adhesion of the materials.
• Application of liquid bitumen. Please note that some formulations need to be heated. Cover the surface with special brushes or sprayers.

• Laying roofing felt. It is laid immediately after the roof has been lubricated with bitumen. This is important, since the composition quickly hardens and loses viscosity. During installation, the roll is gradually spread out and evenly pressed against the base. You can simplify this task using special rollers.
• Installation of subsequent layers. Their number is often 2-3 pieces. The application algorithm is similar to the previously described principle. But when arranging the next sheets, it is important to take into account the location of the joints. It is desirable that the top layer of roofing material overlaps them. At the very end, the entire roof surface is thoroughly lubricated with bitumen mastic.

Now let's look at the principle of installing structures located at an angle. These operations have many nuances.

The covering of these roofs has several common actions:

• Arrangement of sheathing. Technically, it is several wooden planks, which are located over the entire roof area. They are needed to create a base to which the trim will be attached. The pitch between the boards is selected individually. Some Decoration Materials require a completely solid base without gaps ( soft tiles etc.).

In this case, the logs should be covered with sheets of moisture-resistant OSB.
