Repair of a soft roof of a garage: do it yourself. Do-it-yourself garage roof repair - the coating will be as good as new! Repair of the roof of the roof of the garage and house

The roof of a garage of any type needs timely repair, since leaks and other defects are a frequent occurrence during the operation of the premises. Before starting the repair, the scale of the necessary repair is determined, materials are selected and a set of works is carried out.

Repair for leaks in the garage roof

As a result of prolonged exposure to climatic factors, any structure loses its performance characteristics, which contributes to the appearance of cracks, leaks, deformation in the roof. This is typical of roofs of any type, and in each case, certain materials, technologies and tools are used for repairs.

Leaks can also occur in winter time years due to partial thawing of ice and accumulation of water in the place of transition of a warm roof to a cold one

For partial or complete repairs, the following materials and tools are often used, selected depending on the type of roof:

• cement mixture for concrete screed;
• bitumen or mastics based on it;
• roofing material, technonikol, waterproofing and other roll materials;
• polyurethane foam.

How to Repair a Concrete Garage Roof

A roof made of concrete slabs is usually equipped with a slight slope towards the wall opposite to the exit from the garage. This is necessary to ensure the descent of precipitation and to prevent the accumulation of large amounts of snow. There are also buildings with flat roofs, but in such cases, thorough waterproofing of the surface and arrangement of rainwater drainage are important.

If the roof of the garage has a slight slope, it must be waterproofed especially carefully

Long-term operation of a garage box leads to a gradual wear of the waterproofing layer, a violation of the tightness of the seams and joints of the plates. As a result, leaks occur and repair is required. Most often, water enters the room through cracks in the joints. To solve this problem, several effective methods, selected depending on the situation and the condition of the roof. There are the following problems and ways to fix them:

• on a new roof made of concrete slabs, not equipped with waterproofing, make concrete screed to level the surface to prevent moisture build-up. After that, roofing material is melted on the dried surface or bitumen mastic is applied. Liquid rubber is also effective. The entire surface is treated with these materials;

  Concrete screed eliminates all surface irregularities that could cause water accumulation

• the roof, covered with old roofing felt, is cleaned of this material, cracks are found and they are covered with bitumen mastic. If necessary, you can treat the entire surface with a waterproofing compound;

  Roofing material is fused with a gas burner with overlapping cloths on top of each other

• a practical solution for an old or new garage roof is the priming of concrete slabs followed by the application of roofing material. To do this, the surface is cleaned of dirt and debris, dried, carefully treated with bitumen mastic, first with one layer, and after it has dried - with the second. Next, the welded roofing material is attached using a torch;

  For better sealing, the roof surface can be treated with two layers before fusion bituminous mastic

• applying liquid rubber is an expensive but effective measure for repairing small cracks and waterproofing a concrete slab roof. The product is sprayed on the entire roof, but the high cost of the material makes it cost-effective only for large areas.

  Liquid rubber is commonly used on large roofs

To apply any of the above repair technologies, you will need the following tools:

• building level;
• spatulas and hard brushes;
• rules of different lengths for leveling liquid rubber;
• industrial hair dryer or gas burner;
• metal brush;
• master OK.

All tools must be reliable and safe, and personal protective equipment must be used when spraying liquid rubber or fusing roofing material.

Repair of a metal roof of a garage

A concrete, brick or metal garage may have a metal roof, but this material is susceptible to corrosion. As a result, rust, cracks and cracks appear, through which moisture enters the room. Before carrying out repairs, determine the location of the slots and the scale of the work required.

The metal roof of the garage is most often made of sheet metal 3-4 mm thick

The metal roof can be made of metal sheets, the thickness of which is about 3-4 mm. Leaks are formed in different places, depending on what the method of repair work is determined. The main situations are the following:

• small gaps in the area of \u200b\u200b\\ u200b \\ u200bthe junction of the roof and walls can be sealed with tow. The metal surface should be treated with waterproofing paint or liquid rubber to eliminate small cracks. All work is carried out on a dry surface;

  Liquid rubber is often used to waterproof large metal roofs

• on a gable metal roof, holes can form at the junction of the planes. In this case, the welding method is most effective, which requires special equipment, as well as sheets of metal slightly larger than the hole. Such patches are welded in places where cracks are formed, eliminating leaks;

  Small sheets of metal are welded in places where cracks and through holes appear

• leaks at the junction of walls and metal roofs can be neutralized with foam, sealants for outdoor use. The entire roof can be treated with roll-up waterproofing materials.

  You can close up small defects in the roof of a garage made of corrugated board using polyurethane foam

Roll materials are not suitable for filling large holes, but the welding method is optimal. To prevent leaks on the roof of the garage, it is worth laying roofing material, having previously treated the surface with bituminous mastic.

How to repair the roof of a garage from corrugated board

A brick, concrete or metal garage can have a profiled sheet roof. The shape of the roof can be gable or flat with a slope. In any case, long-term operation, climatic conditions contribute to the appearance of holes, violation of the waterproofing layer. Rafter system is often the basis of a roof made of corrugated board and therefore the roof covering must reliably protect the room from leaks. In the event of defects in the profiled sheets, the roof is repaired.

The roof made of corrugated board reliably protects the garage from precipitation until defects appear in it due to long-term operation

The main stages of roofing repair from corrugated board are as follows:

Video: roof repair from corrugated board

A major garage with a soft roof is especially prone to leaks and requires timely repair. This is due to the fact that the soft roof covering does not have high technical characteristics and long service life. A soft roof can be deformed as a result of severe climatic influences and mechanical damage.

With a large number of holes, cracks, leaks, a complete replacement of the coating is recommended. To do this, remove the old layer of material with an ax or other suitable tool, and then apply a new one. This method is suitable when replacing soft roof on a harder surface.

The old roof covering is removed with an ax

For partial renovation and eliminate small leaks using an ax, knife, trowel and spatula. The technology of work is expressed in the following:

1. For a partial repair of the garage roof, bitumen mastic and roofing material are required. On the damaged area, make a cross-shaped cut, bend the edges of the old material and apply heated bitumen inside, and then lay a piece of roofing material, the size of which corresponds to the hole.

   Bitumen is applied to the inner surface of the damaged area and a piece of roofing material is laid

2. After laying such an internal patch, a layer of bituminous mastic is applied, and then the bent edges of the material are pressed. Then the outer patch is cut out, the size of which should be 15–20 cm larger than the incision.
3. The patch is fixed with bitumen mastic, the edges are also coated with this compound, and sprinkled with sand on top.

   The outer patch should be 15-20 cm longer and wider than the damaged area

If the soft roof of the garage is covered with a network of small cracks that form leaks, then it is best to treat the entire roof completely with bitumen mastic or liquid rubber. The first composition is applied with a brush in several layers after each previous one has dried, and liquid rubber is applied by spraying.

Repair materials

There are several main universal types of roof leakage protection materials. They have a service life of over 10 years, strength and resistance to mechanical stress. Such properties are typical for roll and coating waterproofing options, which are optimal for a garage.

Modern roll roofing materials are often used to cover the garage.

Application of roll materials "Technonikol" for roof repair

"Technonikol" is a roll material for waterproofing roofs different types... The structure of the web consists of several layers, and the lower layer is bitumen, which melts during installation and ensures a thorough fixation of the web. This material is optimal for a concrete roof, but it can also be used on a wooden roof with a solid sheathing.

Roll coating "Technonikol" consists of several layers, the lowest of which is bituminous

The method of applying this material on a concrete roof requires the following steps:

1. The surface is cleaned of dust and dirt, dried and leveled with a concrete screed. After the leveling layer has dried, work can be continued.

   Before starting work, dirt and old coating must be removed from the roof.

2. A bituminous primer is applied to the roof, which is necessary to improve the adhesion of the material to the roofing surface and wait for the composition to dry. Next, a small part of the roll is rolled out from the corner of the roof and, with the help of a gas burner or a building hair dryer, the lower part of the canvas is heated, rolling the roll as needed.

   When mounted on pitched roofsah should use safety ropes

3. After installation, each strip is rolled with a roller. This is necessary for a better adhesion of the material to the surface. Each subsequent strip must be laid with an overlap of about 8 cm on the previous one. Thus, the canvases are mounted in two or three layers. In the area of \u200b\u200bparapets, the lower layer is raised by 25 cm, and the upper layer by 5 cm. All areas of junction are isolated with a special bitumen tape.

Coating "Gidroizol" for garage roofs

Often, for waterproofing and preventing leaks of the garage roof, the bitumen-polymer composition "Gidroizol" is used. It does not require warming up before use, easily eliminates cracks and small cracks in the surface. After drying, a one-piece coating is obtained, which has a service life of tens of years and withstands intense climatic influences. With the help of "Gidroizol" you can not only completely process the surface, but also fill in small gaps and cracks, eliminate holes in the roofing felt, process visors and other areas of the garage roof.

Liquid "Gidroizol" is produced in containers of different volumes

The technology for working with liquid "Gidroizol" has the following features:

1. The surface of a concrete or wooden roof is cleaned of dust and dirt, which helps to enhance the adhesion of the composition.
2. The clean surface is primed with a primer based on "Gidroizol" and allowed to dry for 3 hours.
3. Before use, the composition should be diluted with Solvent in a ratio of 1:10.
4. The product can be applied to the surface with a roller, brush and other painting tools.

After processing, the surface does not allow moisture to pass through, therefore "Gidroizol" is widely in demand for waterproofing

Roll material "Gidroizol" allows you to completely process the roof of the garage and provide reliable protection from leaks. The material is a rolled sheet. High strength, simple installation, long service life and resistance to moisture make Gidroizol popular and effective for wooden or concrete roofs and metal coatings.

Roll material "Gidroizol" consists of a bitumen-polymer binder, reinforced with glass cloth and treated on top with a special coarse-grained dressing

The main stages of using roll material:

1. First, they clean the surface, make a concrete screed on the slab roof and dry it.
2. In case of mechanical installation of the canvas on a pitched roof, the material is rolled out along the bottom of the roof and fixed with staples and a stapler. Subsequent sheets are laid with an overlap of about 10 cm on the lower ones, and the joints are coated with bituminous mastic.
3. The hot method of installation is optimal for flat roofs and is carried out using the TechnoNIKOL waterproofing fixing method. The roll is gradually rolled out over the surface, the lower part of the canvas is heated, pressing it with a roller.

Repair with roofing material

Roofing material is often used to renew the waterproofing layer of the roof without dismantling the old coating. With the help of such material it is possible to protect against leaks as wooden roof with solid lathing and slab concrete roof of the garage. At the same time, it is still recommended to remove the old layers of roofing material before installing a new canvas, which will provide good protection of the roof from moisture.

Roofing material with a bituminous layer is often used for roof waterproofing

The technique for processing a roof with roofing material is as follows:

1. The roof is cleaned of dust and dirt. With the help of polyurethane foam, roofing mastic or cement mortar, all existing gaps are sealed.
2. The day before installation, rolls of roofing material need to be rolled out and allowed to rest. If there is not enough space for laying out, you can simply rewind the material in the opposite direction.
3. The roof surface should be primed. To do this, use one of the composition options:
   
4. From the lower edge of the roof, begin laying the lining roofing felt with an overlap of sheets of 10-15 cm. Fastening is carried out using bitumen or mastic. At least 2 layers of lining are required, the edges of which are tucked under the eaves of the roof and fixed with slate nails.
5. The top layer is made of roofing material with a coarse sand powder. The canvases are fixed with an overlap, smearing all joints with mastic.

   For the top layer of a soft roof, sand-tipped roofing material is used

Repair of a garage roof with mastic

Manufacturers waterproofing materials represent a wide range of roofing mastics for roofing different types. Such products are viscous compositions based on polymers, bitumen, rubber, tar, butyl rubber. Liquid formulations allow you to eliminate small leaks in concrete, wood, metal roofs... Their use consists in simply applying the product to a clean and dry surface using a brush or roller. It is possible as a complete treatment of the roof, and spot application in several layers after each previous one has dried.

Mastics are presented in an assortment of different manufacturers

Waterproofing mastics are often the basis for laying roll materials. This ensures maximum protection of the roof from leaks so that repairs do not take a long time. It is possible to use mastics as an independent waterproofing, but always in several layers.

Repair with bitumen

A classic and simple material - bitumen - is in demand for repairing concrete roofs. The product is presented in the form of solid rectangular blocks of black color. The material must be placed in a metal container and heated to 120 ° C. The molten composition hardens very quickly, but thoroughly eliminates all cracks. Therefore, the use of the tool requires skills and dexterity. It is recommended to melt the material in small portions, filling the cracks in turn. If the entire roof is processed completely, then the liquid is distributed over the surface with a T-shaped long stick.

Hard bitumen must be warmed up before use

How to fix a roof leak from inside a garage

Small leaks in the roof or in the area where the roof meets the wall can sometimes be repaired from inside the garage. To do this, you need to inspect the problem area, determine the size of the gap. Cracks up to 1 cm wide can be repaired with polyurethane foam. Beforehand, it is worth drying the leakage area with a construction hairdryer or other suitable method.

Small cracks can be easily repaired with foam

If the gap is more than 1 cm wide, then it is worth using a cement compound. On the dried surface, the product is laid with a spatula. It is possible to apply several layers after drying each previous one. Such methods are relevant for repairing a concrete garage roof. It is possible to eliminate leaks in the metal roof by welding or laying waterproofing outside. If the coating is soft, then you can apply and polyurethane foambut it is best to renovate the roof outside.

Leaks occur on all types of garage roofs and require elimination of the causes. The modern choice of materials, characterized by simple application, makes it easy to repair the roof with your own hands, without changing the old coating to a new one.

Why do garage owners have to deal with the repair of roofing? Basically, in garage cooperatives, buildings are connected into an integral massif, in which moisture, temperature drops almost do not affect the walls. Most often the roof becomes unusable, which experiences all the "delights" of weather conditions.

Reasons why partial or complete replacement of the roof covering is required, some. Basic:

• Use of substandard materials;
• Unprofessional installation of the coating;
• Negligence, poor knowledge of technology, violation of the preparatory stage of work;
• Untimely replacement of individual parts of the roof, which complicated the nature of the work.

DIY garage roof repair

Do not delay with the start of repair work... The further, the more difficult it will be to fix the defect. Measure the surface area, calculate required amount materials, purchase them with a small margin.

You can eliminate roof defects yourself. Take yourself an assistant - it will be more convenient. Study the features of installation of various coatings, consult with experts - and get started.

The garage roof is leaking. What to do

What to do if the roof of the garage is leaking? The first step is to determine how large the leakage area is. You need to understand the reason for their occurrence. If you are the owner of a garage in a cooperative, try to negotiate with neighbors to jointly replace the common roof, if they also have similar problems. You may be lucky and they will agree. But this is not always the case. Then repair the roof yourself.

Important: inspect the condition of the roof at least once every six months in order to notice the appearance of cracks or other defects in the coating in time.

Garage roof repair materials

There are two types of roofing:

• Soft roofing (roofing material, glass cobite, bikroelast, glass-fiber insulation);
• Rigid roof (slate, metal, corrugated board).

Each type of material has both advantages and disadvantages.

Soft roof, using self-melting materials is quite simple to perform, it costs less than a hard coating, flooring is done quickly. But the service life does not exceed 7-8 years, because the surface does not tolerate temperature extremes, especially the scorching sun, and is afraid of dampness.

Metal and slate coating more durable (from 10 years and more), less susceptible to mechanical damage, resistant to the vagaries of the weather. But moisture can lead to the formation rust stains... Often the blame is the poor quality of the material or surface damage (scratches, chips) that arose during the installation of the coating.

Repair of the roof of the garage with corrugated board. Issue price

Profiled sheeting is used for the device of pitched roofs in detached garages. The material is durable, high quality, but sometimes it requires repair.

You need:

• Yardstick;
• Circular saw or jigsaw for cutting sheets;
• Screwdriver.

Repair stages:

1. Determine the scope of work (replacement area);
2. The spoiled material is removed;
3. Check the condition in which the rafters are currently located;
4. Most often, leaks appear due to damage to the waterproofing layer. It is necessary to lay a new one and replace the crate;
5. Next, they begin to mount the metal sheets. Solid sheets are enough for a garage of a regular size;
6. Work starts from the edge. Important: do not immediately fix the corner on top of the sheet. Lay the next two and check how even they are located (whether the lines of the ridge and ends coincide). The sheets are fixed with self-tapping screws, which have a cap or nut that prevents water from entering the attachment points;
7. The material is overlapped, overlapping the adjacent sheet in one wave;
8. Screws are screwed on from above and below the corrugated board through the wave, and in the middle of the sheet, a checkerboard pattern is needed for greater strength of the connection.

The price of colored corrugated board with a polymer coating: 155 - 240 rubles. for 1 sq. meter. The cost depends on the type of coverage, texture and manufacturer. Even if you have to replace most of the coverage in an ordinary garage measuring 5.5 x 3.7 m (S \u003d 20.35 sq. M), then the issue price will be only 3155-4885 rubles). Plus self-tapping screws and a waterproofing layer (from 55 rubles per square meter). The cost is acceptable.

In most cases, it is necessary to change only individual sheets on which defects have appeared, which greatly reduces the cost of work.

Repair of a garage roof with roofing felt. Issue price

Shed and flat roofs often covered with roofing material. This material is used for roofing works more than a dozen years and has gained popularity among garage owners due to its low cost and simple installation process. Selective repairs are also easy to do, especially if cracks are noticed in time.

How to repair such a garage roof? Not so long ago, more modern self-melting materials appeared on the market, but the principle of arranging and repairing a roof with their use is the same as that of roofing material.

Devices and tools for work:

• Ordinary blowtorch or gas torch;
• Strong knife;
• Stairs;
• Strong rope;
• Bituminous mastic (for roofing material);
• Gas cylinder.

Operating procedure:

1. It is necessary to remove the old coating, clean the surface of debris and carefully seal all the cracks with special bitumen mastic. If necessary, make a new screed;
2. When the screed is completely dry, roofing material can be laid;
3. Bituminous mastic is melted in containers up to 200 degrees below, lifted up with a rope and applied to the roof surface. Resin is the last century. It dries quickly and leads to cracks;
4. The roll is heated with a blowtorch, unrolled and overlapped onto the previous strip. Sunset leaves at least 15 cm, and sometimes a third of the width. The excess is cut off. Lay two layers: one - along, the other - across;
5. Seams, joints are carefully coated to ensure tightness. You can use mastic;
6. For the replacement of individual damaged areas, the procedure is the same. The damaged roofing material is cut out in the right place and the roof is "patched".

How much does roofing material cost? The price for 1 roll is about 370-390 rubles. Number of meters per roll - 15 sq.m. Mastic for gluing roofing material costs an average of 600 rubles. for a bucket of 9kg. Euroruberoid Stekloizol (roll 15 sq. M) -770 rubles, Bikroelast (15 sq. M. In a roll) - 322 rubles, Technoelast (roll of 10 sq. M.) - 1680 rubles. per sq.m.

Garage roof replacement

At first, determine what needs to be replaced: one roof covering over another or completely produce full replacement roofs with the installation of a new wooden lathing. It all depends on whether new wooden structures are needed for another type of roofing material.

Bituminous tiles and ondulin require continuous lathing, and metal tiles and slate - discharged. Have you decided to change the slate coating to bituminous shingles? Then you will need to install additional wooden structures, which is associated with some difficulties and will cost more.

Replacing slate with metal tiles will be very simple. It will be more difficult to make a covering from corrugated board instead of bituminous shingles, because additional crate is required.

When arranging a new roof take into account the mistakes that led to the need to replace the structure or roofing material. Replacing a garage roof is a rather complicated process, so be careful in your work and follow the technology of installing the coating.

• Only work in dry and warm weather. Such weather conditions should be maintained for about 2 days before the start of repair work;
• If you have chosen a soft roof, notice if there are trees next to the garage... Leaves that fall on the roof will slow down the outflow of rainwater, begin to rot and lead to the development of fungi and the appearance of mosses;
• Follow the rules fire safety when installing a soft roof. The molten mastic has high temperature, therefore overalls and shoes - required condition for work;
• You need to cover the garage with roofing material together... It's much more convenient this way;
• Talk to neighbors, find out what their garage is covered with and how the coverage serves in the data climatic conditions... Consider their recommendations.

Do-it-yourself garage roof repair anyone with patience and a minimum of skills can do it. You need to decide what is more important for you - ease of installation or durability of the coating. If the first option - then choose a regular or euroruberoid. If you want the coating to last much longer without repairing and replacing roof parts, pay attention to the metal tile and corrugated board with a polymer coating.

There are several technologies for repairing a garage roof with your own hands. The choice of a specific technique restoration work depends on the level of wear of the roof, its type and directly on the type of motorhome.

The restoration of the roofing of a house for a car is currently carried out using three main technologies: soft materials, hot bitumen, tiles or profiled sheets. Private garages are mostly covered with inexpensive and at the same time durable materials - modern ondulin and shingles, corrugated board. You can easily select the optimal method for "treating" the roof of an RV based on the type of roof covering.

Regardless of the technology chosen, you will need to qualitatively prepare the roof for repairs. Inspect the roof, establish the level of its operational wear, determine the roofing elements that must be replaced without fail. In cases where the old coating as a whole is still quite suitable, remove only problem areas by cutting them out with an ax. Subsequently, they can be replaced with new elements, significantly reducing the cost of repair work.

Roof preparation for renovation

If the covering was made with roofing material or a similar material (equipped with a soft roof), swelling and cracks often appear on it over time. Such problem areas must be dealt with even before the start of repair activities. It is not difficult to do this: cut the defective areas crosswise with a well-sharpened knife; Bend the resulting triangles and clean out debris and dust from them.

When carrying out repairs, you will need to fill such areas with corrected defects with bitumen. Below we will tell you more about how to correctly perform such an operation. Thoroughly clean the roof surface, rinse with water if necessary. Now you can start recovery activities.

Bitumen is a popular material that provides high quality self-repair work. Repairing the roof of the garage with its help will require you to stock up on such equipment: a ladder, an old bucket without holes, gloves, gasoline and firewood, a rope, a metal hook, bricks.

Repair of a garage roof with bitumen

The work technology is as follows:

1. Build a brazier for heating using bricks, and make a fire under it.
2. Put a bucket of bitumen poured into it on the fire and wait until the material acquires the required plasticity.
3. Use a metal hook and rope to lift the bucket to the roof.
4. Fill the defective areas of the roof with plastic material. You can use a board made of wood to direct the bitumen stream in the desired direction.

When filling, pay special attention to the places that you cut into preparatory stage... Such areas must be filled completely. This prevents water from entering the garage through the roof during rain. All soft roofs or exclusively damaged areas can be filled with bitumen.

For a long time, domestic home craftsmen have performed roofing repairs using roofing material. It is treated with a special mastic (bituminous) and placed on damaged areas of the coating. In general, the technology of roof restoration with roofing material looks like this:

1. Cut pieces of material according to the required geometric parameters.
2. Pour mastic inside the holes on the roof (you can also use molten resin).
3. Cover the defective areas with pieces of roofing material.
4. Fill the made patch with mastic.
5. Bend the holes cut crosswise, place another piece of roofing material on top of them (in size it must be slightly larger than the area being repaired) and pour the mastic again.

Roofing material can be used to update the entire area of \u200b\u200bthe roofing. In this case, you will need to fill the garage roof with tar. After that, lay sheets of roofing material on it (an overlap within 13-15 cm is required). It is recommended to fill tar in parts. Then it will not have time to freeze, and you calmly repair the entire roof piece by piece.

Roofing material for roofing repair

Sometimes bubbles form on the surface of the roofing material during installation. Nothing wrong. Use a knife to cut them, and then press (as tightly as possible) the cut sections to the roof and apply another layer of tar on them.

If you want your garage roof to be 100% protected from precipitation, it is recommended to lay two layers of roofing material. Then you will definitely get a very reliable coating that will not let a drop of water into the caravan. It is even easier to repair a garage roof with bikrost. To carry out such a restoration, you do not need to purchase tar and mastic. The bikrost is laid with a gas burner. The scheme is as follows:

1. Roll out a roll of material (about half a meter).
2. You heat the wrong side of the bikrost with a gas unit.
3. Press (you will need a special stick in the shape of the letter T) the heated material to the roof.
4. Stand with your feet on the area just laid, roll out another 50 cm roll, repeat the steps to heat the bikrost and install it.

Note! All subsequent strips of material should be laid with an overlap of 7-9 cm.The cost of repair with bikrost is significantly more expensive (3-4 times) than the restoration of a roof with bitumen or roofing felt. But with its help, you can restore the roofing in just a couple of hours. Labor costs when using bikrost are minimal!

If your motorhome is protected from above with metal tiles or corrugated board, their repair is also quite simple. Not difficult to replace at all separate element shingles or mount a new profiled sheet. True, when the need arises to completely replace the roofing, the cost of such work will be tangible due to the high price of the used coatings.

Installation of new profiled sheets on the roof

The metal tile is mounted on the roof from the bottom up. For its installation, universal self-tapping screws with a special rubber gasket are used. Gasket products can be made by yourself. It is even easier to purchase them at a hardware store. There are latches on the lower and upper edges of the tiles. With their help, you will carry out the installation of products (the operation is overlapped). There is no point in describing the procedure - everything is really simple.

You will have more trouble with the replacement of roofing from corrugated board. We'll have to stock up on a circular saw, a twisting device. Perform work according to the scheme below:

1. In the upper corner of the roof (choose any) you mount a profiled sheet (experts advise to start with just grabbing it slightly with a screw).
2. Attach two more products in series.
3. See if the edges of the sheets line up with the line of the roofing ridge. Align them if necessary.
4. Fasten the roofing products tightly.

Pro tip! It is best to fix the middle of the profiled sheets in a checkerboard pattern, and their lower and upper parts through the wave.

How to block the roof of the garage?

If you decide to repair the garage roof, you need to decide on the materials. There are two types of them: soft and hard roofing. Each of them has its own merits. Here short description of all commonly used types.

• Roofing material.

Its main advantage is its relatively low price. But he also serves, as already mentioned, up to 10 years. In addition, it is very flexible and protects well from moisture. Best used for covering flat roofs.

With roofing material, it may be difficult to determine the required amount. If the roof of the building is flat, then three or even four layers are needed, since it will need to protect the roof from water that stagnates on its surface. Fewer layers are needed if the slope is significant.

For a longer service life of roofing material, it is advisable to install it in sunny weather.

• Decking.

It is very simple to work with this material, the installation is quick. However, it has good durability and low cost. It will last long enough.

If the material used in the restoration of the roof does not need to withstand strong and frequent temperature changes and a lot of precipitation, it is advisable to use corrugated board. Thanks to sheets different sizes it won't take long to cover.

But working with corrugated board should be very careful, because damage to the polymer coating will inevitably lead to corrosion, which will negatively affect the service life of the entire structure.

The corrugated board is installed on a crate, which is made of boards or beams, and a layer of waterproofing is spread under it. Thanks to such a system, the building will be reliably protected from leaks.

• Slate.

It is the most common material and is very popular, because it combines excellent quality for little money.

Coating the roof with a cipher is very similar to working with corrugated board: here it is also necessary to lay a layer of waterproofing under the battens made of beams. Apart from this, it also has waves.

A feature of working with slate is the need to prepare holes for roofing nails in advance, since fragile material can crack if you start screwing screws into it.

Major and minor repairs

To understand if there is a need for repair, you need to inspect the surface. Anyone can carry out the manipulation, it is enough to climb up the garage. Repair can be minor and major.

Small repairs to the garage roof are needed when minor damage is detected, usually leaks, they appear due to hail, corrosion of the object material and sheets torn off by the wind.

You can correct the situation yourself, using mastic to seal the holes or replacing some elements with new ones. But if you realized late and the area with defects is too large, then in this case, a major overhaul is necessary.

Overhaul of garages is carried out quite rarely, when more than 40% of the roof area is damaged, and the better the work is done, the longer you can forget about such problems.

Roof repair is a laborious process that requires knowledge and skills from a specialist, choosing our Moscow masters for all steps of the repair, you provide reliability and a guarantee for the services received.

A garage roof leak risks not only damage to building structures and the need for serious repairs. Water trapped inside a building can damage tools, equipment and materials in storage. garage usually does not require special training and can be done independently.

Preparation for renovation work

The roof is the most vulnerable place of the building, since it is exposed to the most destructive atmospheric influences. The resistance of a soft roof to external influences directly depends on the characteristics of the coating material. Most often, it is an affordable roofing material, but modern fused materials can also be used to equip a garage roof.

At the preliminary stage of work on repairing the roofing with your own hands, you should carefully examine the roof in order to determine the degree of damage to the flooring. If there is some damage on the surface, you can limit yourself to local repair of the corresponding sections of the roof deck. Serious deterioration of the coating is a pretext for replacing the entire roofing carpet or creating a new outer layer of the roof from roll material, mastic or liquid rubber.

If the garage has a roof with a slope of at least 5 degrees, then the repaired roofing carpet made of roll materials can be left as a waterproofing coating, the lathing can be mounted on top of it and the roofing can be laid from a suitable sheet material.

Depending on the results of the roof audit, a repair method is selected and the required amount of materials is purchased.

Before proceeding with the restoration soft coating do it yourself roofs, the entire flooring surface should be thoroughly cleaned of debris and all types of contamination, and dried mastic should be removed. In places of through holes in the coating, the outer layer is opened by means of a cross-shaped incision ("envelope"), the edges are folded back, dirt and moisture are removed from the base. Areas with badly worn roofing felt should be cut out with an ax. Next, it is required to dry the roofing well, paying special attention to the opened places before local repairs - they are most efficiently dried using a construction hairdryer or a gas burner.

Preparatory and renovation work it is necessary to carry out only in dry weather during the warm season - the air temperature should be at least 10 ° С.

Local repair technology on the roof of the garage

To repair individual sections of the soft roof, bitumen mastic and roofing material will be required. In the opened prepared "envelope" it is required to put a piece of roofing material, cut exactly to the size of the envelope, after carefully smearing the hole with well-heated bitumen to exclude the possibility of moisture penetration into the inner layers of the roofing carpet. A layer of bituminous mastic is applied over the laid inner patch and the folded edges of the “envelope” are pressed tightly. The outer patch should extend 15-20 cm beyond the edges of the repaired area. A cut piece of roofing material of the required size is also glued with mastic. For maximum reliability, it is coated on top with a layer of bitumen (special attention is paid to the edges adjacent to the roof), and sprinkled with a layer of sand. After the mastic has dried, excess sand should be removed.

If a worn-out piece is cut out in the coating, the resulting cavity is filled with roofing material of appropriate sizes and heated bitumen. The external patch is laid according to the above technology.

To ensure reliable adhesion of the patch to the existing roof deck, it is recommended to remove the outer protective layer of roofing material, consisting of fine-grained mineral chips. To do this, you can use solar oil, which will soften the material, and a metal spatula... The oil is applied with a brush or brush.

Restoration of the outer layer of the roof in the garage

If the roofing material roof has traces of general wear and tear due to aging of the material under the influence of ultraviolet radiation, temperature changes and moisture, which is expressed in a frequent grid of small cracks across the entire surface of the flooring, it can be restored with your own hands using:

• bituminous mastic;
• liquid rubber.

Bituminous mastic is used in a heated form. The repair compound is applied with a brush on roofing material... The mastic fills cracks and provides required level waterproofing material. This view repair does not require serious financial costs, it is available for doing it yourself, but it is important to observe safety precautions when working with heated resin. In addition, during the work, it is recommended to cover the surface already treated with mastic with a layer of sand, which will protect the bituminous material from the destructive effects of ultraviolet radiation and extend the service life of the repaired roof.

Liquid rubber - a more technological and durable coating... The repair composition is a water-based bitumen-polymer emulsion. After drying, the material applied to the roofing acquires the properties of rubber and provides high-quality waterproofing of the surface. If working with two-component liquid rubber requires the use of special equipment, then an affordable cold one-component material can be applied with your own hands using a spatula, brush or roller. The coating successfully withstands temperature extremes, exposure to moisture, UV radiation, and aggressive environments.

Replacing the soft roof covering

To update the outer covering of a garage soft roof, you can use traditional roofing felt or weldable roll material. The first option is cheaper, but the complexity of installation is higher. In the second case, a gas burner is required.

Roofing material is laid on top of a layer of heated bituminous mastic. The bituminous composition is applied to the prepared roof surface in a strip slightly exceeding the width of the roofing material. Roll material is rolled on top, while making sure that no bubbles form. The overlap of the next strip should be 10-15 cm - it is for this width that the edge of the already laid coating should be smeared with bitumen. Discovered bubbles should be opened by making a small incision. Having removed the air from the area under the coating, the roofing material must be pressed tightly to the surface and the incision must be smeared with bitumen.

Before laying, the roofing material should lie down unfolded for a day.

The finished flooring layer should be left to dry for 12 hours. Then the next layer of carpet is installed - it should be done with a slight shift in order to avoid overlapping joints. In this case, the roof covering is able to provide the required degree of waterproofing. The number of layers of roofing material in a waterproofing carpet depends on the characteristics of the roof:

• 5 layers for flat roofs;
• 4 layers with a low slope (less than 15 degrees);
• 3 layers with a slope of 20-40 degrees;
• 2 layers on slopes from 45 degrees.

The lower layers of the carpet are made of fine-grained roofing felt or roofing felt, and for the outer covering it is recommended to roll material with coarse-grained dressing, which is maximally resistant to external influences.

Installation of the overlaid roof can also be done by hand. The cleaned and dried roof is primed with bitumen. Then the roll of material is rolled out about half a meter, and the free end is thoroughly heated with a gas burner. It is important to heat well the corners and edges of the coating to prevent them from lagging behind the surface..

The heated piece of the deposited coating is pressed against the roof surface with a roller. Then the roll is rolled out again by 50-60 centimeters, and the wrong side of the material is well heated by the burner. The strips of material are mounted with an overlap of 7-8 centimeters. The roofing carpet should consist of at least two layers, laid with shear joints. Work on the installation of the welded roof should be done accurately and quickly. It is not recommended to walk on the finished coating until it cools completely - this can lead to a violation of the waterproofing properties of the material.

The optimal choice of repairing the garage roof covering will ensure the reliability of the building roof and protect the property for a long time.
