How to re-cover a concrete garage roof. Covering the garage roof with your own hands: three options. Preparing the garage roof

In this article we will look at the question of how to cover a garage roof correctly. What materials are used for this, what technologies are used. The information will help you understand the problem. After studying it, you will know what to talk about with the craftsmen who are entrusted with the construction garage roof.

Roofing materials

Most garage roofs are flat designs, built over the ceiling. The latter are ready-made reinforced concrete slabs(hollow) or filled one monolithic slab. In both cases, the ceiling is mounted horizontally without any slope. The slope of the roof itself, and this parameter varies between 2-5°, is formed by a screed that is applied to the garage floor.

After that, roofing material is laid on the poured screed in several layers, coating it with hot bitumen or bitumen mastic. This is an old technology that is still used today.

The second method is to use a built-up roof. This is a bitumen-polymer material with a fiberglass base. It is quite durable, with high waterproofing qualities. Will last about 30 years. Compared to roofing felt, whose service life does not exceed 10 years, a built-up roofing is many times better.

But it should be noted that the garage roof is not always flat. Today, more and more often, the owners of this building give their preference to pitched structures. Therefore, single- or gable roofs on garages are often found today. And for them you can already use a fairly large range of roofing materials: asbestos slate, corrugated sheets, metal tiles, soft tiles and others.

Therefore, the question of how to cover the garage roof is not so relevant. Everything will depend on the shape of the roof and the preferences of the owner. Of course, you will have to take into account the budget allocated for the construction of the roof. But let's focus more specifically on the old old technology- roofing felt.

Technology of covering a garage roof with roofing felt

As mentioned above, a flat garage roof is concrete base. It is necessary to pour a screed of concrete mortar onto it, which will create a roof slope. Therefore, along the perimeter roofing structure install formwork from boards. Some people use bricks or blocks. Boards are better because they can be cut at the required angle, which will form the slope of the screed layer being laid.

The boards are fastened together with jibs, metal corners, screws or nails. The main requirement is that the formwork elements do not move apart when pressure is applied to them concrete mortar. It is possible to lay a reinforcing frame made of steel mesh. If the roof area is large, then metal guides are installed on the concrete base. Installation is carried out at the required angle.

Concrete is poured simultaneously, without long breaks (no more than 2-3 hours). After 3-4 days, the formwork is removed; after 15-20 days, the flat roof can be covered with roofing felt.

. In the filters you can set the desired direction, the presence of gas, water, electricity and other communications.

How to do it correctly:

Sweep the flooded and dried screed with a broom, freeing from dust and debris.

Cover it completely layer of bitumen mastic. This layer is intended to strengthen the roof in terms of waterproofing.

After which they produce installation of roofing felt. It is laid in strips in a transverse direction relative to the angle of inclination, coating the base with bitumen mastic. That is, there will be two mastic layers. Strips of roofing felt are laid overlapping with an offset of 10-15 cm. Laying should begin from the bottom of the roof, moving upward. Then the second layer of roofing material is laid in exactly the same way, only not in the transverse direction, but in the longitudinal direction. Bitumen mastic is again coated between the roofing felt layers.

There may be not two, but three layers of roofing material. Then the sequence of laying is as follows: the first bottom is longitudinal, the second is transverse, the third is longitudinal. In this case, for the lower layers, lining roofing felt of the RM or RPP brand is used. The top layer is roofing felt brands RK, RKK or RKM.

Technology of covering a garage roof with a welded roof

Covering a garage with roofing felt is the easiest way to create a roof. But this design will not last long, so manufacturers offer more durable and durable material, which among craftsmen is called euroroofing felt. As mentioned above, this is a bitumen-polymer material with a base made of fiberglass, fiberglass or polyester mesh.

This technology is called built-up technology because the roofing material is laid on the prepared surface of the garage roof using open fire. Therefore, to carry out installation work will be required gas burner and a tank filled with propane.

Before installing a built-up roof, it is necessary to prepare the plane of the roof base. To do this, a roofing carpet is laid on it using bitumen mastic. This is also a roll material on a bitumen-polymer basis. The purpose of the under-roofing carpet is to prepare the base: to level it and become the basis for the euroroofing material to which it will need to be glued.

On our website you can get acquainted with the most – from construction companies, presented at the exhibition of houses “Low-Rise Country”.

Typically, a built-up roof is laid in longitudinal direction with overlapping laid strips. The overlap size is 20-30 cm. They do it like this:

Roll of roofing material lay down at the edge of the roof.

Warm up its reverse side with a torch so that the polymer film being covered begins to melt, crack and tear. This is a signal that the material is ready for installation.

Roll straighten using a metal poker, rolling towards yourself.

The second worker with a spatula or metal roller rolls the material being laid so that it is pressed tightly against the surface of the under-roof carpet and leveled. The main task is not to leave air bubbles under the fused roof.

Shed garage roof

Let's move on to the question of how to cover the garage roof instead of roofing felt. Ruberoid is not used for covering pitched roofs. But euroruberoid can be used. To do this, a continuous sheathing is assembled under it from boards, plywood or OSB slabs, which are covered with bitumen mastic and laid with an under-roofing carpet. The latter is often pierced with roofing nails to ensure fastening strength. Euroroofing felt is mounted in the same way as on a flat roof.

Now, as for other roofing materials. Let's look at how to cover a garage roof with corrugated sheeting. First of all, you need to create a slope pitched roof. This can be done in two ways.

Option #1

By façade wall 1-2 rows of concrete blocks or 3-4 rows of bricks are laid. A board with a cross section of 50x150 mm is laid on top of them. It is attached to the laid materials (bricks and blocks) with wire, which is laid under the masonry, and then thrown over the board, pulling it to the masonry with a knot. The wire installation step is 1 m.

Exactly the same board is installed with opposite side. It is mounted directly to the screed layer using anchors. Now they are installing rafter legs, which are boards with a section of 50x150 or 200 mm. The sheathing is already laid on them, and then the corrugated sheeting.

Option No. 2

On both sides of the garage building, two 50x150 mm boards are laid and secured to the concrete base. From the front side, several support posts are installed vertically on the board with an installation step of 0.0-1.0 m. The posts are the same board, cut into segments. The height of the racks determines the angle of inclination of the garage roof slope. They are attached to a board laid on a concrete base with metal perforated corners and self-tapping screws.

Another exactly the same board is laid on top of the racks. That is, on the façade the structure should look rectangular shape farm. One end of the rafters is laid on it, the other ends rest against a board laid on the opposite side of the garage roof. Subsequently, the farm is covered from the front side: with decking. Plywood, boards, OSB boards.

Installation of corrugated sheets

Of course, covering a garage roof with roofing felt is easier. It does not require a large availability of various building materials. Particularly in this regard, lumber should be noted. But a roof made of corrugated sheets will last up to 50 years if the roofing material itself is properly laid and secured.

A few nuances installation process, which affect the quality of the final result:

You can buy on the market profiled sheets up to 12 m long. They can be cut in the store to different lengths required by the consumer. Therefore, the garage roof is covered with solid sheets without joints. This ensures 100% tightness of the roof structure.

Laying corrugated sheets overlap in the transverse direction with a displacement of one wave.

Fastening made with roofing screws with a wide head and a rubber gasket. This ensures the mounting hole is sealed. The washer is made of neoprene rubber, which does not change its characteristics under the negative effects of changes in humidity and temperature.

Fasteners screw in into the lower wave of the roofing material.

At the edge of the roof, fasteners are screwed into each wave, in the middle through the wave or two.

The roofing screw must be screwed in strictly perpendicular plane roofing.

It is forbidden screw the fasteners tightly or not tighten them. In both cases, there will be a loose connection rubber gasket to the corrugated sheet, which will subsequently lead to leaks.

Asbestos slate

Returning to the question of how to cover a garage roof instead of roofing felt, we note that asbestos slate has long proven itself to be a reliable and durable roofing covering that has served and is still serving humanity. Its service life is a century or more. And this is proven by houses that were built at the beginning of the last century.

Firstly, slate is cheaper than metal roofing materials. Secondly, it will serve faithfully longer than a built-up roof. He doesn't look the most presentable. If this criterion is not in the first place, then asbestos slate is an excellent option.

The nuances of installing slate on a garage roof:

Installation begins from the bottom overhang.

Stack the sheets with overlap in one wave, aligning the edges strictly along the cornice.

Fasten to the sheathing material with roofing nails with a wide head.

Install second row with an overlap on the first one within 20-30 cm. The steeper the roof, the less overlap.

The sheathing is laid so that under each sheet there is three elements, at least. Two on the edge, one in the middle.

Slate sheets of two rows are required joined along the sheathing element.

Bituminous shingles

This roofing covering is available on the market in a huge variety of shingle shapes and color design. As when laying roofing felt on the roof of a garage, here we mean its “Euro” modification; flexible tiles are laid on a solid base, on top of which the under-roofing carpet is laid out.

The tiles themselves are attached to the roof with roofing nails. Bituminous mastic is not used here. This adhesive composition used only for gluing some areas of the roof under the roofing carpet.

Gable roof

For many garages erected as outbuildings on suburban area, this type of roof structure is best option. It fits perfectly into the architecture of the main house. The gable roof has a presentable appearance. But its construction costs more than the two roofs described above.

As in the case of a shed roof, roofing felt cannot be used here. Other roofing materials can be used without problems. They are laid using the same technology as on a pitched roof.

Conclusion on the topic

When solving the problem of covering a garage roof with some material, it is necessary to think through all the nuances regarding the strength and durability of the roofing structure. Of course, in this regard, roofing felt is not the best best option. And its service life does not exceed 5-7 years. But if we talk about simplicity and cheapness, then this is the optimal solution.

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 the spring, 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, and the selected roofing covering.

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). The category of a pitched roof also includes roofing, 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 is connected at a certain angle rafter legs, having support on the walls and at the upper 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 roofing material. It is made of clay and therefore has such advantages as resistance to rust, exposure sunlight, low temperatures and attack by microorganisms. The service life of the coating is long and amounts to about 100 years. The 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. Has several color variations, which allows you to choose it for 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.

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. Made from 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 in case of correct installation. Due to the polymer protective coating 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 rafter system, lay waterproofing, install the 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. Old covering with concrete slab, if any, will have to be removed completely. 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 sealed with cement laitance (or liquid glass), which is applied with a regular wide brush. Wide cracks can be repaired 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 cement layer 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 with 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. Stacked top layer material that 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 again the gas burner comes into play. The previously laid lower layer of material is heated.

Step 6. After the bottom layer is well heated, 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 sheeting

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 according to the level, 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 upper 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. Single sheets overlapped 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 shields are fixed using roofing screws, and the joints between them and the roof are covered with bitumen mastic.

Step 7 On the first bitumen layer fabric strips are glued, 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.

With your own hands, you need to choose material. When choosing it, they are guided by the type of roof and the expected budget. However, all coatings must have certain technical characteristics:

• reliably protected from precipitation;
• have an attractive appearance that matches the design of the roof of the house;
• prevent heat leakage from inside the structure;
• guarantee protection from thieves.

ADVICE: If the garage is significantly removed from the house, you should opt for a more cheap material for the roof.

What is the best and cheaper way to cover a garage roof? All types of quality coatings are divided into two groups:

1. Soft. This type of coating includes roll materials. Cheap The garage roof can be made using roofing felt, rubemast, membrane materials and glass-based coatings. The main advantage of such materials is good waterproofing combined with low cost. But at the same time, their service life is quite short. In addition, these materials are fire hazardous and become very hot in hot weather.
2. Solid. Used for single-pitch and gable frame roofs.

How to cover a garage roof with your own hands? Review solid types of roofing:

Preparing the base

How to cover a garage roof with your own hands? Whichever material The owner did not choose the garage covering; first of all, it is necessary to install waterproofing. This is especially true for flat roofs where snow and water may accumulate.

Waterproofing performs two functions:

• protection against moisture ingress into the room;
• getting rid of steam formed inside the room.

The waterproofing function is performed by a special membrane. It is a material in the form of strips of 10-15 cm. The strips are laid overlapping and glued with special tape.

The strips are attached to the constructed frame in the form of lathing laid on the rafters. The membrane is attached to the sheathing using construction stapler . There must be a gap of 25 cm between the roof and the membrane for.

Waterproofing material It is quite thin, so during installation you should not pull it too hard to avoid tearing. But sagging should also not be allowed. The edges of the membrane are folded, leaving the ends in 20 cm long.

IMPORTANT! When laying, do not mix up the top and bottom layers of waterproofing, otherwise it will not perform its functions.

Coating technology

So, let’s cover the garage roof with our own hands. The quality and durability of a garage roof depends on compliance laying technologies roofing material. Each type of coating has its own installation features that must be followed strictly.

Below we will look at how you can cover your garage roof inexpensively.

Ruberoid

What to cover concrete roof cheap garage? Ruberoid. It is suitable for covering a garage roof with a reinforced concrete base, which must be carefully prepared before laying roofing material. The roof is cleaned of dirt, dried, and leveled as much as possible.

Repair work garage roof are performed in the following sequence:

1. Before laying roofing felt, the base is covered with heated bitumen or mastic.
2. Placed on mastic lining material . A gas burner is used to adhere to the mastic.
3. Rolls are laid out perpendicular to the backing sheets roofing felt. Laying begins from the bottom, gradually overlapping the rolls up to the top edge. The edges of the roofing material should overlap the roof curb and the adjacent roof (if any).

Read more about how to cover a garage roof with roofing felt and other soft roofing materials with your own hands.

Corrugated sheet

How to cover a garage roof inexpensively? One of the options is corrugated sheeting. Installation of sheets is carried out on timber sheathing 60Х40 using special self-tapping screws with rubber linings or special self-tapping screws with special linings of different colors.

Self-tapping screws are attached to the depth of the corrugation. The sheets are fastened together roofing rivets in the color of steel.

It is impossible to fasten corrugated sheets with ordinary nails, as under gusts of wind they will loosen and the sheets come off.

The sheets are laid overlapping over the overhang. The edges are attached along the overhang through one wave. For edges and sides purchased special profile.

The sheathing under any covering must be treated with antiseptic compounds to prevent the formation of fungus and rotting.

Sheets corrugated sheets overlap each other in one wave, with an overlap of 2 to 5 cm in the transverse line. The gaps in the overlaps are filled silicone sealant or bitumen mastic, this will reliably protect the roof from water and snow.

Slate

How to cover a garage roof inexpensively? Can slate. Do-it-yourself installation of a garage roof is carried out according to the same rules as laying corrugated sheets. The sheets are fastened with special galvanized nails with an enlarged head. The nails are driven into top part waves so that water does not flow into the holes formed. The nails are not driven in tightly, to avoid deformation of the sheets during temperature changes, you need to leave gaps of 2-3 mm.

IMPORTANT! You cannot drive nails in immediately with a hammer; you must first drill holes in the sheets so that the sheets do not crack during installation.

Sheets are stacked with overlap 20 cm. For complete joining of adjacent sheets, it is advisable to remove the corners from the internal spans. In rows, the sheets are laid in a checkerboard pattern. With an overlap in the transverse line of at least 3-4 cm. In the longitudinal joints, an overlap is made in one wave.

Cracks and chips are inevitable during the installation process, since slate- quite fragile material. There is no need to replace sheets every time. To fill the small cracks that have formed, use a solution of cement, asbestos, PVA glue and water (2Х3Х1Х1).

Ondulin (or Euroslate)

How to cover a garage roof inexpensively? Ondulin It has been used for over 50 years to cover the garage with your own hands. One of the fundamental points of its choice is ease of installation. Unlike slate, ondulin is flexible and resistant to cracking.

How to make a garage roof ondulin? It is mounted on a lattice made of wooden beams with a cross section of 60X40. The pitch of laying the beams is 45 cm. If the angle of inclination is higher than 15 degrees, the step increases to 61 cm. Additional strips are laid more tightly in the place where the ridge strip is attached.

Sheathing beams must be secured strictly parallel each other, otherwise any errors will lead to deformation roofing sheets. To do this, use control slats inserted between the beams as a control pattern.

ADVICE: You should not skimp on the number of bars. Too large a distance between them will lead to sagging of the ondulin sheets under the load of water and snow.

Before installing the ondulin, it is possible to lay waterproofing membrane , but this is not a prerequisite. For convenience, experienced roofers advise cutting the sheets before lifting them onto the roof; this is much more convenient than attaching required sizes on top. When sawing ondulin, the saw must be lubricated with oil so that it does not get stuck.

Temperature suitable for operation from 0 to 30 degrees. In frost, the sheets will be fragile and there is a risk of breaking them.

In the heat, the sheets will stretch, which will subsequently become deformed.

Installation of sheets begins with markings in the form of a thin line for self-tapping screws.

Work begins from below the roof on the leeward side of the garage.

The correctness and speed of laying the entire roof depends on how correctly you fasten the first sheets. Experienced roofers advise lightly securing the first row and checking horizontal.

Only after the edges are aligned are the sheets secured tightly. The sheets should protrude beyond the edge of the eaves by 5 cm, no more, otherwise the edges will be deformed and the appearance of the roof will deteriorate.

The sheets of the second and subsequent rows are laid overlapping with the waves coinciding, with an overlap of one or two waves in the transverse side, from 20 to 140 mm overlap in the transverse (the greater the roof slope, the wider the overlap of the transverse sides). Required condition is chess order laying sheets of the next rows.

To fasten the sheets to the sheathing, special nails with special heads are used. The cap protects the attachment points from getting moisture. Special monolithic nails for ondulina that can withstand hammer blows.

The nails should be driven into the upper part of the wave. The upper and lower parts of the sheet are attached to each wave, and the central rows are arranged in a zigzag, with one wave missing in each row.

After installing the sheets, the ridge is covered with a special decorative element. The overlap on each side of the slope must be at least 12 cm. Placed under the ridge self-adhesive tape, performing the role waterproofing. The same tape is laid along the edge of the eaves to prevent snow from getting under the roof.

The process of covering a garage requires compliance with the rules for installing the material, but it is quite possible to cope with it yourself. This will significantly save money cash on payment for the work of professionals. Study the technology of laying the selected material, and your garage will be reliably protected from precipitation.

When the walls of the garage are erected, it is necessary to put a roof on the building. Regarding how to cover the roof in a garage correctly so that it is reliable and has a long service life without repair, the answer can be found both in specialized literature and on numerous sites on the Internet. It is necessary to familiarize yourself with the information before proceeding preparatory stage to conduct construction work for the construction of a structure in which the car will be protected from external influences unfavorable to it.

Types of roofs for garages

You can solve the problem of how to cover a garage roof after choosing the type of roof, which, depending on the preferences of the vehicle owner, can be:

After deciding how to cover the garage, they begin to implement the project. Depending on the choice of roof type, they begin to erect a specific truss structure.

Garage roof covering materials

The range of products for covering garage roofs is so diverse that it can be difficult to make a choice. The most popular, according to experts, are corrugated sheets and slate (asbestos-cement or ondulin). The reason for their popularity is considered to be their relatively low cost, simplicity of installation technology, and, therefore, there is no need for the developer to have experience and special skills in performing such construction work. True, minimal knowledge and the desire to build a roof on a garage are still required.

No less famous than slate and corrugated sheeting, a material for covering the roof of a garage, such as ceramic tiles, is more attractive in appearance, but its price is much higher.

Various types coatings for garages have the following characteristics:

Creating a truss structure

After choosing the type of roof and deciding how to cover the garage roof, construction work begins. First of all, you need to build truss structure- this will require wooden beams or boards that do not have knots.

The thickness of the workpieces is selected taking into account the following parameters:

• the distance that must be maintained between the legs of the rafters;
• roof weight;
• length of rafter legs.

Before installing the rafters, it is necessary to lay a mauerlat consisting of special beams, which are laid on load-bearing garage walls along the perimeter of the building. The rafters are attached to these beams, inserting them into pre-prepared sockets using spikes.

Then the outer rafter legs are mounted, and after them the intermediate elements, making sure to level them.

In order to avoid the demolition of the roof during a strong gust of wind, the rafters are nailed to the walls, but first they are attached using wire ropes to crutches built into the wall.

Care must be taken that the well-dried wood used does not have knots, otherwise damage to the ceiling may occur. After creating the rafter system and sheathing, they begin laying the roofing material.

Garage roofing made of roofing felt

Used as a filler following materials:

• fibrous - for example, asbestos;
• dusty - ground limestone, slag dust, sawdust, etc.;
• combined – representing a mixture of dust and fibrous products.

Before applying the coating for the garage roof, the surface of the sheathing is thoroughly cleaned and primed using drying oil with dye. All cracks and crevices on it are sealed. First, the soil is applied across the wood fibers, and then along them. The bitumen is preheated for application. When the primer dries, mastic is applied to the sheathing and roofing felt is placed on it (read also: " "). Next layer roll material laid so that it slightly overlaps the first, and the third is larger than the second at the edges.

Along the entire length of the installation of the roofing covering, roofing material is laid out overlapping so that it extends beyond the ridge of the roof by about 15 centimeters. The formation of bubbles should not be allowed, so during the process it is smoothed out as thoroughly as possible.

How to cover a garage roof, watch the video:

• the size of the overlap with a slope of less than 14 degrees should be at least 20 centimeters;
• when the slope is 15-30 degrees, an overlap of 15 to 20 centimeters is required;
• if the slope of the garage roof exceeds 30 degrees, the horizontal overlap cannot be less than 10 centimeters and more than 15 centimeters;
• in the case where the slope is less than 14 degrees, overlaps, both vertical and horizontal, are sealed using silicone sealant.

The size of the sheathing is chosen in full accordance with the height of the corrugated sheeting of the material used and the angle of inclination of the roof slope. Sheets of this roofing product are attached to wooden elements roof structure into the lower part of the wave, using special self-tapping screws with a sharp drill and a neoprene gasket. The ridge is fixed in its upper part with large self-tapping screws.

When the slope level is no more than 15 degrees, it is required continuous lathing with an overlap equal to two waves. If the slope exceeds this parameter, then the sheathing pitch should be in the range from 35 to 50 centimeters.

According to experts, any materials can be used for the roof of a garage, the main thing is to properly carry out the rafter structure and be sure to waterproof the roof.

A garage is not a simple place to store your car. For most, this room becomes a workshop, warehouse, and even conservation storage. However, regardless of the functions of this room, it is extremely important to quality roof. This article tells you more about how to re-roof a garage with your own hands. You will learn about several technologies, namely the use of roofing felt, ondulin, slate and metal profiles. By comparing all the technologies, you can make your choice.

Types of roofing materials

Today you can re-roof your garage without much difficulty. Moreover, modern market offers wide range building materials. All of them are divided into the following categories:

1. Rolled. This includes euroroofing felt, stekloizol and roofing felt.
2. Metal profiled sheets. In particular, we are talking about metal tiles and metal profiles.
3. Asbestos cement slate sheets.
4. Euroslate, ondulin with bitumen impregnation.

Each of these materials has its own characteristics and differences. Moreover, you need to use different technology ceilings It is also worth noting that the choice of roofing material for a garage roof depends on its shape.

Garage roof shapes

There are several types of garage roofs, which are:

• Single-pitch.
• Gable.
• Three- and four-slope.
• Attic.

Based on what type of roof you have, you should select the material for covering it. Let's look at the features of each roof separately.

Single slope with low slope

If you build your garage yourself, then such a roof is the easiest option. For such suitable for roofing a number of roofing materials, for example, corrugated sheets or roofing felt. As for corrugated sheeting, it is recommended to use material with a wave height of at least 40 mm.

Advice! In conditions of a pitched roof, it is not recommended to use slate or ondulin to cover the garage roof. These materials may not be able to handle the load of snowfall and may crack under the weight.

Gable

A gable roof requires the installation of rafters. Mostly the slope of such a roof is around 15°. Due to this, it is possible to lay absolutely any roofing material. The only difference will be that depending on the material used, the roof preparation technology will differ.

So, if a sheet covering such as slate, ondulin or metal profile is laid, then a sheathing must be made. As for the rolled material, here you need to sew up the continuous surface of two slopes slab material. Afterwards, a waterproofing layer is laid, and roofing material is fused on top.

Advice! If your area is considered to be quite windy, then it is not recommended to use lightweight materials such as ondulin or metal profiles for installation on the garage roof. It may not withstand the load of the wind and fall off the base.

If in your region there is large number precipitation, then you can lay a metal profile. Due to the longitudinal stiffening ribs, it can cope with the possible load. Also take into account the fact that if the garage is heated, then the gable roof of the garage should be insulated. Due to this, you can reduce heat loss and save on heating this room.

Three- and four-pitched roof

This type of roof is rarely used for a garage. However, there are admirers of such complex shapes. For such a roof, you should carefully consider choosing the appropriate roofing material. Using a metal profile is not the best option. Why? Given the large number of corners and slopes, a large amount of waste can be generated. However, there are no clear requirements and rules.

Mansard roof

Often located under the garage attic room. In this case, the roof can acquire the most different shapes. The slope angle can reach up to 45°. To reduce the overall load on the rafter system, it is not recommended to use heavy roofing material, for example, asbestos cement slate and the like. Preference should be given to metal profiles or ondulin. In this case, be sure to carry out waterproofing and thermal insulation work.

How to cover a garage roof

Now let's look at several technologies that are widely used today when covering a garage roof. At the same time, we will see how to correctly perform these processes.

We invite you to consider the method of covering the roof:

• roofing felt;
• asbestos-cement slate;
• corrugated sheeting;
• ondulin.

Covering with roofing felt

This material falls into the roll category. As already mentioned, it is used mainly on flat roofs. Ruberoid is laid on the prepared roof surface. As a rule, a screed has already been made on the roof; the roofing material is glued to it using a special mastic or under the influence of high temperature using a gas heating pad.

The roofing material may contain a special coating, asbestos fibers or similar materials. If the flooring will be carried out on wooden base, then it should be completely free of cracks and possible gaps. The bitumen should be heated immediately before starting work.

Advice! The primer is applied in the first layer across the fibers of the beams and boards. The next layer is already along the fibers.

The roofing felt is laid with an overlap of up to 150 mm. This will provide enough lock to prevent water leakage. Each joint is carefully processed under the influence high temperatures. Pay attention to every detail. For example, to prevent roofing felt from swelling when laying, constantly smooth it until it sets.

Covering the garage roof with slate

Considering the weight of the material, first of all, you should make high-quality preparation of the rafters. The slate is laid on the sheathing. It is made of boards 250 mm thick and 100 mm wide. As for the bars, their cross-section should be 60×60 mm.

Advice! To prevent roof leaks, first lay a waterproofing film under the asbestos-cement slate.

The slate is laid along the wave with an overlap. Such slate is fastened with special nails. The nail should be driven into the upper wave. There are also asbestos-cement slate sheets without waves. For their fastening, it is recommended to make special holes to prevent thermal expansion.

Corrugated sheeting for garage roofing

This material became lately the most common. And this is not surprising, because it has a large number of advantages. The most important advantage is light weight. However, the use of this floor for a garage should take into account the angle of the roof:

• If the slope is about 14° or less, then the overlap should be up to 200 mm. With all this, such a joint should be sealed.
• If the slope exceeds 15° and is in the region of up to 30°, then the overlap should be 150-200 mm.
• If the garage roof slope exceeds 30°, then the overlap is even smaller and can reach up to 100 mm.

To fasten the corrugated sheeting, a special self-tapping screw with a gasket is used, which prevents leakage. The self-tapping screw is screwed into the bottom wave. Be sure to fasten the skate, especially if you have gable roof. Special attention should be paid to the sheathing. Its pitch is determined based on the height and width of the wave on each sheet.

Covering with ondulin

Considering that ondulin soft material, for its installation it is recommended to sheathe the sheathing OSB sheet completely. Thanks to this, even under the influence of snow it will not break. The principle of its fastening is reminiscent of the principle of installing corrugated sheets or slate. It is worth noting that special nails or screws for ondulin are used for fastening.

Conclusion

So, we have examined with you all the features of how and with what to cover the roof of the garage. We hope that this material will be useful to you and you will be able to make your choice suitable material for covering the roof. When installing, be sure to follow the fastening technology specified by the manufacturer. Remember that you can do all the work yourself, the main thing is to have the desire to learn.
