A leaky roof poses a danger not only to the structure of the garage, but also to the tools and materials that may be in the area. As a rule, there is an overabundance of tools in the garage, both manual and electric. Such tools can easily become damaged if water regularly falls on them. That is why this article will give tips on how to repair a roof in a garage with your own hands. These tips will help you protect your structure from damage and maintain the integrity of your tools.

Do-it-yourself garage roof repair is quite simple. The main condition will be the use of high-quality materials and strict adherence to roof repair technology. There are two types of roofing - soft and hard; depending on the type of roof, the materials for its repair will differ both visually and financially. Let's look at how and what to use to repair some of the most popular types of roofing.

Preparation for repair work

The first thing you need to do is determine the level of surface wear, as well as find those roof parts that need to be replaced. In addition, you should plan your time well so that you can devote it to this work. sufficient quantity time. After all, if it suddenly comes heavy rain, and the roof of your garage will be partially or completely dismantled, then the entire room may suffer quite a lot. The choice of work to be performed will be important; evaluate the surface of the roof because you may have to not only dismantle some of its elements, but the entire roof.

Rolled and sheet materials Often they are repaired much faster than piece ones, for example, tiles. Since one sheet of corrugated board can cover up to 9 square meters, and a sheet of flexible tiles is only 0.14 square meters of roof surface. Agree that such work will take you much more time and effort, because in order to cover 9 square meters you will have to install 63 sheets of tiles.

Before carrying out repair work, it is necessary to remove all debris that may be on the roof. Pay special attention to those areas that will be repaired. If the garage roof is covered with soft materials, for example, roofing felt or waterproofing, then cracks could form on their surface over time and require repair. Such cracks must be repaired before major repairs. Using a sharp knife or other object, you need to make a cross-shaped cut, which will later be sealed with bitumen or other material of your choice.

Repair of soft garage roof

Nowadays, there are quite a lot of soft roofing materials, the most common being bicrost and roofing felt. The first option is installed by fusing a gas burner, and the second option is laid on bitumen mastic. Therefore, we can come to the conclusion that installing bikrost is much easier, because you will not need to spend extra time applying mastic.

Bikrost

As mentioned above, when installing bikrost you will not need to use tar and mastic. A gas burner is used to install this material. And in order to attach it to the surface, you must first apply a layer of oxidized bitumen, thanks to which the material will easily bond to the base.

This material is installed gradually, you need to carefully roll out the roll to a distance of 50-60 cm. Next, the rolled out side of the bicrost needs to be heated with a burner, and during the process of laying it, press the material with a T-shaped stick. To press the material to the surface, you can place your feet on it and at the same time roll out and heat the next half meter. Having covered the first row, remember that the second layer of bicrost should be installed overlapping the first. The overlap should be at least 8 centimeters.

One of the main advantages of this material is that it is applied very quickly. For example, an ordinary garage under a car You can cover it in about an hour and a half. When carrying out repair work with bitumen or roofing felt, you will have to spend much more time. However, this material has one serious drawback - its price, which is slightly overpriced.

Ruberoid

Repairing a garage roof with roofing felt is not difficult. If upon inspection of the surface you decide that major replacement you don’t need the roof, then to repair individual parts, simply cut out several pieces of roofing felt of the appropriate size. The main thing is not to make a mistake in size and choose the appropriate piece that will cover the damaged area.

First, you need to apply a layer of bitumen mastic to the damaged hole. After which it is necessary to secure a piece of roofing material, and secure it on top with a second layer of bitumen mastic. Completely dry There is no need to wait; you can immediately bend the triangles into place, pressing them tightly. Next, you need to patch the cuts with another piece of roofing felt, the edges of which should overlap the base of the roof. And on top of the patch, apply a layer of bitumen mastic, thanks to which you can achieve greater strength of the material.

If you decide to completely cover the entire roof using roofing felt, remember that this installation should be done on a pre-installed layer of tar. And the roofing felt sheets are laid with an overlap of 10 centimeters. If bubbles appear on the surface during installation, they must be cut off, after which they will be sealed with another layer of tar.

Pay special attention to the joints between your garage and neighboring garages. As a rule, cracks often form in such places, as well as peeling of old materials.

For a high-quality overlap, one layer of roofing material is sufficient, since when installed, this material forms a single sheet, which will be an excellent protection against moisture penetration. However, if you live in an area where weather conditions are not very good, then the use of two layers of this material will contribute to a longer service life and high-quality protection against moisture penetration into the garage. One of the main advantages of roofing material is its low price.

Hard roof repair

Often, solid roofing materials such as:

Garages covered with corrugated sheets, metal tiles or slate are repaired quite simply. After all, it’s not at all difficult to repair or replace a single sheet of corrugated sheeting or other material. However, if you have to completely replace the entire ceiling, then doing this work may cost you much more, and you will spend a lot more time.

As for metal tiles, repairing individual parts of this material is even easier than replacing corrugated sheeting. Metal tiles are much smaller than other roofing materials. To install such tiles, self-tapping screws with a rubber gasket are used. In order to install the product, there are latches on the edges of the tiles, thanks to which you can easily dismantle the old material and replace it with a new one. The procedure is quite simple, even a person who has nothing to do with roof repairs can easily replace the material.

In the event that you need to completely replace the entire roofing material and want to change it to corrugated sheeting, then you need to know the order of work that you need to follow. Work related to the installation of corrugated sheets:

Conclusion

In order to repair your garage, it is not necessary to contact expensive specialists. After all, you can perform such repairs yourself. And in order for the roofing work to be carried out efficiently, follow all the tips that you read in this article. And the video below will help you visually see what is required of you.

The garage is a second home. And if in the first place a woman maintains order and comfort, then in the garage, as a rule, a man watches everything. It doesn’t have to be warm and cozy here, but respect necessary requirements Dryness and reliability are simply essential. A leaky roof can become a serious challenge for the owner if it is not patched in time. We will talk about how and how to repair a garage roof in this article.

The method of roof repair directly depends on the type of construction, the type of roof itself and, of course, the degree of its wear. Often, a garage is built a short distance from a residential building and is made from inexpensive roofing materials: corrugated sheets, metal tiles, ondulin and flexible tiles. As for collective garages, you can’t get by with tiles. Soft bituminous materials are more suitable for them. There are several ways to repair garage roofs: hot bitumen; soft roofing materials; tiles or corrugated sheets. Preparatory work First, you need to determine how badly the roof has been damaged and pay special attention to failed elements that need to be replaced. Most quick repair Do-it-yourself garage roofing is done using rolled or sheet building materials. Piece ones will take much more time, so if the rainy season is upon us and the roof has gaping holes, then it is better to do everything quickly. Stages of preparatory work: Clear the roof of leaves and debris. Inspect the surface to assess the extent of damage. It is quite possible that patches in problem areas will be enough for repairs. Remove problematic and leaky roofing elements for subsequent replacement. If old roof was covered with roofing felt, and you saw cracks or bubbles on it, then they must be eliminated before repair work begins. Use a sharp knife to cut the problem areas crosswise and fold back the edges. Clean the space inside from dust and dirt, if any. Later, you can simply fill these recesses with hot bitumen. Repair with hot bitumen Repairing a soft garage roof is usually done using hot bitumen. Required materials and tools: bitumen; bucket (it’s better to choose a bucket that you don’t mind, because it will be “disposable”); a rope with a metal hook at the end to lift the bucket onto the roof; ladder; bricks to make an “oven” to heat the bitumen; a stiff brush to remove dirt from problem areas; construction gloves. Stages of work: Clear the roof of leaves and dirt and heat the bitumen on an improvised barbecue made of bricks. When the mass becomes pliable and plastic, you can begin pouring. Using a rope with a hook, lift the bucket of molten bitumen onto the roof and spot-fill problem areas with it. If you have the desire and opportunity, you can completely cover the roof with bitumen to certainly eliminate the possibility of leakage. Set the direction of the bitumen using a flat wooden board, leveling it over the surface. Wait for the material to dry. Repair with soft materials Soft roofing materials are quite often used to repair garage roofs (photo). These include bikrost and roofing felt. And if the latter can be laid on bitumen mastic, then to lay bicrost you will need a gas burner. Despite this, working with bicrost is much easier and faster, because you don’t have to bother with preparing and pouring mastic. Ruberoid Repairing a garage roof using roofing felt is not that difficult, especially if you just need to install a few patches. Just cut required amount pieces and cover the prepared areas with it. The only caveat is that the measured piece must exactly match the size of the hole, otherwise all efforts will be useless. Steps to create a patch: If you decide to cover the entire roof with bitumen, the progress of the work will be somewhat different, and it will take much more time. Stages of work: Clean the roof from dirt and dust. Apply a layer of tar, the width of which will correspond to the width of the roofing material. Lay the “strip” of roofing felt on the greased area. Cover the next section of the roof with tar, slightly overlapping the previous piece of roofing material (about 10-15 centimeters), and lay the canvas again. Continue in this manner until you cover the entire surface with roofing felt. Helpful advice: if bubbles appear during installation, simply cut them with a knife, release the air and press firmly onto the tar. For 100% waterproofing, you can coat them on top again. If your garage is adjacent to neighboring ones, then when laying roofing felt, pay special attention to the places where the material joins other roofs. Usually these are the “weakest” places where cracks most often appear. We invite you to familiarize yourself with useful video about repairing a garage roof using roofing felt. As a rule, one layer of roofing felt is enough to ensure that your garage is reliably protected from moisture, but if the operating conditions are too harsh, or you live in a region with high humidity and frequent rain, then it is better to lay two layers. The cost of repairing a garage roof with roofing felt usually does not exceed 600-700 rubles. The material itself is inexpensive (from 200 to 300 rubles per roll), bitumen mastic or resin costs about 100 rubles per bag, and other materials and tools can be found in the same garage. Bikrost If roofing felt repairs seem too complicated and energy-intensive to you, we bring to your attention bikrost. To install it, you do not need to fill in bitumen mastic or resin. All you need is a gas burner and oxidized quick-hardening bitumen. This is a special type of bitumen that “sets” very quickly and is firmly attached to the base. Stages of work: Roll out the bicrost roll to 50-60 cm and heat it with a burner from the wrong side. Quickly press the heated material onto the roof surface with a T-shaped stick. Stand with your feet on the freshly laid area, roll out the roll a little again and repeat the procedure, laying the second strip overlapping by 7-9 centimeters. Such work will take a maximum of one and a half hours of work, and the quality of waterproofing will be no worse than from professional installation of roofing material. The price of repairing a garage roof with bicrost will be a little higher, but not so much that you won’t be tempted by the short deadlines for work. So, keeping your garage dry and cozy will cost about 1,500 rubles. Repair with corrugated sheets and tiles Separately standing garages, as a rule, covered with metal tiles, flexible tiles or corrugated sheets. And if replacing a damaged segment of corrugated sheeting is not difficult, then you will have to tinker with the tiles. Corrugated sheet To repair a garage roof with corrugated sheets, you need to stock up on some simple tools. You will need the sheets of material themselves, a tape measure, Circular Saw and a screwdriver. Usually separate garages covered with solid sheets of corrugated sheets, which are not built up, as is the case with metal tiles. In this case, it is necessary to make a side overlap, and one such “wave” is quite enough to ensure proper waterproofing of the entire room. Since the width of a corrugated sheet is approximately a meter, for an ordinary five-meter garage you will need 5 sheets. Stages of work: Use a screwdriver to secure the first sheet of corrugated board in the upper corner. Do not tighten the fastener all the way so that if necessary, its location can be adjusted. In the same way, fasten a couple more sheets and check whether the line of the roof ridge coincides with their edges. Align the sheets and finally secure them with a screwdriver. Secure the upper and lower parts through a “wave”, and the middle part in a checkerboard pattern. Metal tiles Covering the garage roof with metal tiles will take a little more time. Despite the obvious labor intensity, today most people choose this method because metal tiles look beautiful and impressive. On the market you can choose absolutely any colors and turn your garage into the envy of all your neighbors! Metal tiles should be fastened starting from the bottom and moving to the very top of the roof. For fixation, use screws with rubber gasket so that the metal does not “move” and become loose. In addition, the gaskets will provide additional waterproofing at the fastening points. Lay the elements overlapping, using special latches at the top and bottom of the sheets. This will give an even more reliable grip. Repairing your roof is easy, especially if you have a passion for construction. Having done such work at least once with your own hands, you will gain valuable experience that will be useful to you more than once in the future.

Any type of garage roof needs timely repairs, since leaks and other defects are a common occurrence during the operation of the premises. Before starting repairs, the scope of the necessary repairs is determined, materials are selected and a set of works is carried out.

Repairing garage roof leaks

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

Leaks can also occur in winter time year due to partial thawing of ice and accumulation of water at the transition point between the warm roof and the 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 felt, technoNIKOL, hydroisol and other rolled materials;
• polyurethane foam.

How to Repair a Concrete Garage Roof

Roofing from concrete slabs It is usually arranged with a slight slope towards the wall opposite the exit from the garage. This is necessary to ensure precipitation and prevent the accumulation of large amounts of snow. There are also buildings with a flat roof, but in such cases it is important to thoroughly waterproof the surface and arrange for the removal of rain moisture.

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

Long-term use of a garage box leads to gradual wear of the waterproofing layer and disruption of the tightness of seams and slab joints. As a result, leaks occur and repairs are 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 condition of the roof. The following problems are encountered and ways to resolve them:

• on a new roof made of concrete slabs, not equipped with waterproofing, they make concrete screed to level the surface, which will prevent moisture accumulation. After this, roofing material is fused onto 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 felt is fused using a gas burner with the sheets overlapping each other

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

  For better sealing, the roof surface can be treated with two layers of bitumen mastic before fusing.

• Application of liquid rubber is an expensive but effective measure for repairing small cracks and waterproofing concrete slab roofs. The product is applied by spraying onto the entire roof, but the high cost of the material makes it cost-effective only for treating large areas.

  Liquid rubber is usually used on roofs with a large area

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 when spraying liquid rubber or fusing roofing felt, personal protective equipment must be used.

Metal Garage Roof Repair

Concrete, brick or metal garage may have a metal roof, but such material is susceptible to corrosion. As a result, rust, cracks and crevices appear, through which moisture enters the room. Before carrying out repairs, you should determine the location of the cracks and the scale of the necessary work.

A metal garage roof is most often made from sheet metal 3–4 mm thick

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

• small gaps in the area where the roof and walls meet 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 often used for waterproofing large metal roofs

• On a gable metal roof, holes can form in the area where the planes meet. 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 form, eliminating leaks;

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

• Leaks at the junction of walls and a metal roof can be neutralized with polyurethane foam and sealants for external use. The entire roof can be treated with rolled waterproofing materials.

  You can repair small defects in a garage roof made of corrugated sheets using polyurethane foam.

Rolled materials are not suitable for eliminating large holes, but the welding method is optimal. To prevent leaks, roofing felt should be laid on the garage roof, having previously treated the surface with bitumen mastic.

How to repair a garage roof made of corrugated sheets

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

A roof made of corrugated sheets reliably protects the garage from precipitation until defects appear in it due to long-term use.

The main stages of corrugated roof repair are as follows:

A solid garage with a soft roof is especially susceptible to leaks and requires timely repairs. This is due to the fact that the soft roof covering does not have high technical characteristics and long service life. Soft roof may be deformed as a result of strong climatic influences and mechanical damage.

At large quantities holes, cracks, leaks, a complete replacement of the coating is recommended. To do this, remove the old layer of material using an ax or other suitable tool, and then apply a new one. This method is suitable when replacing a soft roof with a more rigid covering.

Old roofing is removed with an ax

For partial repairs and small leaks, use an ax, knife, trowel and spatula. The technology of work is expressed as follows:

1. To partially repair the garage roof, you will need bitumen mastic and roofing felt. A cross-shaped cut should be made in the damaged area, 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 bitumen mastic is applied, and then the bent edges of the material are pressed. Then an 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 sand is sprinkled 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 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 species materials to protect the roof from leaks. They have a service life of more than 10 years, strength and resistance to mechanical stress. Such properties are typical for roll and coating options for waterproofing, which are optimal for a garage.

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

The use of TechnoNIKOL roll materials for roof repairs

"Technonikol" is a rolled material for roof waterproofing various types. The structure of the canvas consists of several layers, and the bottom layer is bitumen, which melts during installation and ensures thorough fixation of the canvas. This material is optimal for concrete roofing, but it can also be used on a wooden roof with continuous sheathing.

The TechnoNIKOL roll coating consists of several layers, the lowest of which is bitumen

The method of using 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, you can continue work.

   Before starting work, you need to remove dirt and old coating from the roof.

2. A bitumen primer is applied to the roof, which is necessary to improve the adhesion of the material to the roof surface and wait until the composition dries. Next, roll out a small part of the roll from the corner of the roof and, using a gas burner or a hair dryer, heat the lower part of the sheet, rolling out the roll as needed.

   When installing on pitched roofs, safety ropes should be used.

3. After installation, each strip is rolled with a roller. This is necessary for 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 ​​parapets, the lower layer is raised by 25 cm, and the upper layer by 5 cm. All abutment areas are insulated with a special bitumen tape.

"Gidroizol" coating for garage roofing

Often, the bitumen-polymer composition “Gidroizol” is used to waterproof and prevent garage roof leaks. It does not require heating before use and easily eliminates crevices and small cracks in the surface. After drying, a solid coating is obtained that has a service life of tens of years and can withstand intense climate impacts. Using "Gidroizol" you can not only completely treat the surface, but also fill small gaps and cracks, eliminate holes in roofing felt, treat canopies and other areas of the garage roof.

Liquid “Hydroizol” 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 “Hydroizol” and allowed to dry for 3 hours.
3. Before use, the composition should be diluted with Solvent solvent in a ratio of 1:10.
4. The product can be applied to the surface using a roller, brush and other painting tools.

After treatment, the surface does not allow moisture to pass through, which is why “Gidroizol” is widely in demand for waterproofing

Rolled material "Gidroizol" allows you to completely process the garage roof and ensure reliable protection from leaks. The material is a canvas rolled into a roll. High strength, simple installation, long service life and resistance to moisture make Gidroizol popular and effective for wooden or concrete roofs and metal coverings.

Rolled material "Gidroizol" consists of a bitumen-polymer binder, reinforced with fiberglass and topped with a special coarse-grained coating

The main stages of using rolled material:

1. First, clean the surface, make a concrete screed on the slab roof and dry it.
2. When mechanically installing the canvas on pitched roof the material is rolled out along the bottom of the roof and secured 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 bitumen mastic.
3. The hot installation method is optimal for flat roofs and is carried out according to the TechnoNIKOL waterproofing fastening method. The roll is gradually rolled out over the surface, the lower part of the web is heated, pressing it with a roller.

Repair using roofing felt

Roofing felt is often used to update the waterproofing layer of a roof without dismantling the old coating. With the help of such material you can protect against leaks like wooden roof with a continuous sheathing, and a slab concrete garage roof. However, it is still recommended to remove old layers of roofing material before installing a new sheet, which will provide good protection of the roof from moisture.

Ruberoid with a bitumen layer is often used for roof waterproofing

The method of treating a roof using roofing felt is as follows:

1. The roof is cleaned of dust and dirt. Using polyurethane foam, roofing mastic or cement composition, seal all existing cracks.
2. The day before installation, rolls of roofing felt 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, they begin laying the lining roofing material with an overlap of sheets of 10–15 cm. Fastening is carried out using bitumen or mastic. At least 2 layers of lining material are required, the edges of which are tucked under the roof eaves and secured with slate nails.
5. The top layer is created from roofing felt with a coarse sand powder. The canvases are fixed with an overlap, coating all joints with mastic.

   For the top layer of a soft roof, roofing felt with sand is used

Garage roof repair using mastic

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

Mastics are presented in an assortment of different manufacturers

Waterproofing mastics often serve as the basis for laying rolled materials. This ensures maximum protection of the roof from leaks so that repairs do not require a long time. It is possible to use mastics as 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 a temperature of 120 °C. The molten composition hardens very quickly, but thoroughly eliminates all cracks. Therefore, using the product requires skill and dexterity. It is recommended to melt the material in small portions, filling the cracks one by one. If the entire roof is being treated, then the liquid is distributed over the surface with a long T-shaped stick.

Solid bitumen must be heated before use.

How to Fix a Roof Leak from Inside a Garage

Small leaks in the roof or where the roof meets the wall can sometimes be repaired from inside the garage. To do this, you need to examine the problem area and determine the size of the gap. Cracks up to 1 cm wide can be sealed with polyurethane foam. You should first dry the leak area with a hair dryer or other suitable method.

You can easily seal small cracks with polyurethane foam

If the gap size is more than 1 cm wide, then it is worth using cement composition. Apply the product onto the dried surface using a spatula. It is possible to apply several layers after each previous one has dried. Such methods are relevant for repairing a concrete garage roof. Leaks in a metal roof can be repaired by welding or installing waterproofing on the outside. If the coating is soft, then polyurethane foam can be used, but it is best to repair the roof from the outside.

Leaks occur on all types of garage roofs and require elimination of the causes. A modern selection of materials that are easy to use makes it easy to repair the roof yourself without replacing the old covering with a new one.

How to repair a garage roof - good question, requiring study. A do-it-yourself garage roof is not a problem now, and during its construction it is worth thinking about the subsequent repair of this structure. There are several technologies that make it easy to repair a garage roof yourself. The choice of a specific method for carrying out restoration work depends on the degree of wear of the roof, its design and directly on the type of garage.

Making a garage roof with your own hands is a serious task. Any roof covering breaks down over time and requires repair. Restoration of garage roof coverings is currently carried out using three main technologies: hot bitumen, soft materials, tiles or corrugated sheets. Private garages are most often covered with cheap but durable materials - ondulin, flexible tiles, profile flooring.

Regardless of the chosen restoration technique, you will need to thoroughly prepare the roof for repairs: inspect the roof, determine its level of wear, and identify roofing elements that need replacement. In cases where the old coating is still quite suitable, only problem areas can be removed - they will be easy to replace with new ones, while significantly reducing the cost of repair work.

When the old coating was made of roofing felt or similar soft material, it usually develops bulges and cracks over time. With such problem areas must be sorted out before repair work begins. This is done simply: with a well-sharpened knife, you need to cut the defective areas crosswise, bend the resulting triangles and clean out debris and dust from them.

Once the roof is thoroughly cleaned and washed, you can begin repairing your garage roof.

Restoring a garage roof with hot bitumen

Bitumen – popular in Lately material that provides high quality Do-it-yourself garage roof repair. To carry out repairs using bitumen, you will also need a certain tool: a ladder, an unnecessary bucket without holes, gloves, gasoline and firewood, rope, a metal hook, bricks.

The technology for carrying out the work is as follows:

• Using bricks, a barbecue is built for heating and a fire is built under it.
• A bucket filled with bitumen is placed on the fire. Here you need to wait until the material becomes sufficiently plastic.
• Using a metal hook and rope, a bucket is lifted onto the roof.
• The resulting plastic material is used to fill defective areas of the roof. Here you can use wooden board to give the bitumen stream the desired direction.

When pouring, special attention should be paid to those places that were specially prepared for initial stage. These areas must be filled completely. Then, when it rains, moisture will not penetrate into the garage through the roof.

Important! Bitumen can be used to fill the entire soft roof or only damaged areas.

Restoring a garage roof with bicrost and roofing felt

Roofing repairs have long been carried out by many home craftsmen using roofing felt. To do this, it is treated with bitumen mastic and placed on damaged areas of the coating. IN general outline roof restoration technology using roofing material looks like this:

• Pieces of material are cut according to specified geometric parameters.
• Mastic is poured inside the holes on the roof (molten resin can also be used).
• Defective areas are covered with pieces of roofing felt.
• The completed patch is filled with mastic.
• On top of the holes cut and bent crosswise, another piece of roofing material is placed, slightly larger in size than the area being repaired, and the mastic is poured again.

Ruberoid can be used to renew the entire roof. To do this, you will need to fill the roof with tar. Next, you need to lay sheets of roofing felt on it (an overlap of about 13–15 cm is required). It is advisable to pour the tar in parts so that it does not have time to harden, and the roof can be easily repaired.

Sometimes, when laying, bubbles form on the surface of the roofing material. In this case, using a knife, they must be cut and pressed as tightly as possible to the roof, and then an additional layer of tar must be applied on top of them.

Important! For maximum protection of the roof from precipitation, it is recommended to lay two layers of roofing material.

Repairing a garage roof with bicrost is even easier. To do this, you do not need to buy tar and mastic. Bikrost is laid using a gas burner. The process looks like this:

• A roll of material is rolled out (approximately half a meter);
• Heats up gas unit reverse side of bicrost;
• The heated material is pressed against the roof (here you will need a specially prepared stick shaped like the letter T);
• Next, you need to stand on the newly laid area with your feet, roll out the roll another half a meter and again repeat the above steps for heating the material and installing it.

Important! All subsequent strips of material must be laid with an overlap of 7-9 centimeters.

The cost of repairing with bicrost is noticeably more expensive than restoring a roof with roofing felt or bitumen. However, with its help, you can restore the roofing in just a few hours, and labor costs will be minimal.

Restoration of hard roof covering

Knowing how to make a garage roof safe and secure is essential, and rigid roof coverings are often used to achieve this. When the garage is protected from above with metal tiles or corrugated sheets, repairing its roof on your own is also quite simple. In this case, it is usually necessary to replace a separate damaged tile element or install a new corrugated sheet. But with a complete replacement of such a roofing, both the cost of work and labor costs will be much higher.

Installation of metal tiles on the roof is done from bottom to top. To install it in the garage with your own hands, use universal self-tapping screws with a special rubber gasket. Such gaskets can be made independently or purchased separately at a hardware store. Latches are provided on the top and bottom edges of the tiles. They are used to install overlapping products.

Replacing a roof made of corrugated sheets will be more complicated. Here you need to stock up on tools such as a construction tape measure, a circular saw and a device for tightening stainless steel screws. The work is carried out according to the following scheme:

• A corrugated sheet is mounted in the upper corner of the roof (you can choose any one). It’s better to start by just grabbing the part a little with a screw.
• Two more products are attached in series. The edges of the sheets must coincide with the line of the roofing ridge.
• Roofing products are firmly fixed.

Important! It is optimal to fasten the middle of the profiled sheets in a checkerboard pattern, their upper and lower parts - through the wave.

Build good roof- this is only half the battle, it is worth remembering that any roof needs regular maintenance and restoration. It may seem to inexperienced craftsmen that only professionals can do this, however, using modern technologies and roofing materials, you can repair the garage roof yourself without any problems.

Car owners, whether they are amateurs or experienced drivers, spend most of their free time in the garage. A truly masculine atmosphere reigns here, where you can spend hours changing spare parts, oils, chatting in the company of auto repairmen, and just spend your day off profitably. The whole idyll can be spoiled by a leak in the roof, which must be eliminated as quickly as possible, otherwise it can increase several times in a short time.

When is garage repair required?

The first sign that a garage is unsuitable for further use in most cases is the appearance of moisture in the room itself after rain or melting snow. Even a minor leak can cause damage to the car, the appearance of dampness, and fungal growths. Any deformed area of ​​the roof needs timely repair.

The reason for garage roof repair may be:

• adverse effects of weather conditions;
• bad ecology;
• non-compliance with the stages of roofing work;
• improper preparation of the premises;
• poor quality materials used;
• lack of timely repair of minor roof defects;
• violation of waterproofing due to destruction of the bitumen layer;
• Wetting of the insulation, which leads to swelling of the under-roof covering;
• negative impact ice formed due to melting snow covers.

Only a well-built garage can guarantee the safety of your car.

Types of repair work

Repairing a garage roof is not as difficult as it seems, which is ensured by an acceptable installation work the height of the room and the small size of the roof itself.

It all starts with determining the scale of the upcoming repairs and necessary materials. Depending on the degree of damage to the old roof, the repair can be partial, when individual deformed parts are replaced, or major, when the structure must be completely dismantled. The roof can be covered with different materials - metal tiles, slate, corrugated sheets, which have different performance properties and costs.

Depending on the condition of the roof, major or local repairs may be required

Overhaul of a heavily damaged roof structure

It is recommended to plan major repairs during a warm period with minimal precipitation, but in this case there are exceptions. If the situation does not tolerate delays and requires immediate elimination of defects, then repairs are allowed in any weather, but then it is necessary to stretch an awning over the roof, protecting it from rain and snow. Due to the small size of the garage, repairs are usually completed in one day. If installation is delayed, then at least waterproofing should be installed within the first 24 hours.

Most often, the garage roof begins to leak

At major renovation It is important to pay attention to removing the old coating. If the old roofing felt is in good condition and laid in 2-3 layers, then it can be left as waterproofing. In case of significant damage, the coating is carefully removed from the structure. If there is a reinforced concrete base, it is more convenient and faster to remove the material using an ax, with wooden frame you will have to remove the layer with a knife and a grabber.

Work with the roof is carried out only if the temperature indicated on the packaging is observed. If roof repairs are carried out in winter, then the material should first be kept in a warm room (15–20 degrees) for about 4 hours and only then installation should be carried out.

Depending on the area of ​​the roof, the complexity of the work, and the selected materials, an estimate is calculated, which includes the following costs:

• for transportation of materials;
• surface preparation;
• coating deposition;
• repair of junctions and pipes.

The average cost of 1 m 2 of reliable roofing is 100 rubles; choosing a cheaper option does not guarantee long-term operation of the structure.

A properly repaired roof will last for years.

Current repairs - an opportunity to inexpensively restore the functionality of the roof

Soft roofing is often subject to defects in the form of punctures, tears, leakage of seams and adjacent elements, it swells and even gradually slides. However, the presence of any of the listed flaws does not mean the formation of leaks, but requires elimination.

Current repairs, unlike major repairs, involve work to restore the original functions of the coating to no more than 10% of the total area.

Description of the sequence of repair work

The traditional classification of roofing is represented by 2 types:

• soft roof, famous example which is roofing felt;
• rigid roofing in the form of slate, corrugated sheets, metal tiles.

Depending on the chosen option, a set of tools is selected. To install soft material, you must prepare the following:

If a hard roof is being laid, the following is required:

• tape measure for taking measurements;
• jigsaw or circular saw for cutting material to the desired size;
• self-tapping screws with a screwdriver;
• ladder to get to the roof.

Features of slate roof repair

Slate, being a long-term choice of builders, meets all quality requirements at a low cost. This material will last for several decades and is resistant to temperature fluctuations and fire. The disadvantages of sheets include the difficulty of transporting them due to their heavy weight and fragility.

Slate is both durable and fragile material

Preparation of the structure for laying any roof is the same:

1. Initially, the sheathing is installed and backing layer roofing felt for insulation against moisture leakage.
2. Sheets of slate are attached in rows so that each subsequent one partially overlaps the already finished one.
3. To fix the material, special nails with a sealing gasket are used.

How to properly repair a metal garage roof

The most common material to choose is corrugated sheeting or metal tiles.

Profiled sheets are well suited for pitched roof structures because they are resistant to mechanical loads, provide good waterproofing, do not require adjustment to the pattern, and will last at least half a century. Among the disadvantages of this coating are a strong knocking sound during rain or hail, and the damaged polymer layer is susceptible to corrosion.

You can seal the leak with mastic

To replace the corrugated sheet covering:

1. Remove damaged material and conduct an inspection load-bearing structures.
2. When a leak occurs, new waterproofing is installed and the sheathing is changed, after which metal sheets are installed from bottom to top, overlapping.
3. The coating is attached to self-tapping screws along the lower and upper edges of the sheet through one wave, the rest of the sheet is fixed in a checkerboard pattern.

A budget option for replacing a garage roof is metal tiles, which come in a variety of color scheme and durability, will last 30–50 years. She is not afraid of temperature fluctuations and minor mechanical damage. The only disadvantage of such repairs is the cost of the product.

Initially, the coating is mounted on the sheathing and a layer of vapor and waterproofing, and subsequent repairs are carried out using self-tapping screws with a special gasket. The material is fastened at the top and bottom of the sheet.

Concrete roof: reasons for repair, stages of work

If a leak is detected in a concrete roof, we can talk about non-compliance with the construction installation technology or very long-term operation. In this case, complete dismantling and replacement of the entire layer of thermal and waterproofing cannot be avoided. If it is damaged only upper layer material, you can fill them with liquid rubber.

The concrete roof of the garage begins to leak if the installation technology is not followed.

Despite the complexity and duration of repair work, the result will please you for many years. Concrete structure not susceptible to deformation high pressure snow masses, has impeccable waterproofing.

Repairing a concrete garage roof is carried out in stages:

As a roofing covering for a concrete roof, you can use roofing material or waterproofing. In great demand as alternative material uses liquid rubber.

Liquid rubber is excellent waterproofing material

Roof repair made from soft roofing materials

Before you start repairing the garage roof, it is important to prepare not only roofing felt and bitumen mastic, but also a set of tools:

• sharp ax with knife;
• construction hair dryer;
• gas burner with gas cylinder;
• a broom or broom for cleaning the roof surface;
• trash container.

Standard garage cooperatives are built in rows, so to completely replace their roof, the owner will have to negotiate with the owners of other garages to repair the entire roof at once. If you start work without warning your neighbors, you can significantly damage your relationship with them, because when repairing your part, you will inevitably have to deform nearby coverings.

Soft roof the garage requires repairs most often

Sequence of work:

Other materials can be used for routine repairs:

1. Bitumen. Its main advantage is non-flammability. Bitumen also retains heat well, so it can be used as a thermal insulation material and provides a sufficient level of sound insulation. Most often, this material is used due to its increased resistance to precipitation, especially where it rains very often.
2. Roofing mastic. This material is ideal for small local repairs. Mastic is also used as a fastening material for partial replacement. Its peculiarity is that before use it must be heated to a temperature of 160 degrees. As the mastic cools, it hardens. This material perfectly protects the roof from mold when high humidity. Can be used to repair roofs made of any material.
3. Membrane roofing. This material tolerates both heat and cold and is resistant to moisture and corrosion. The main advantage is that it can remove steam and heat from the garage.

Step-by-step description of replacing the old coating:

Elimination of bloating

It's very easy to do this:

1. The gravel topping is removed from the material, after which you can open the bubble that appears with a knife.
2. Inner surface The cut material is covered with cold mastic on both sides, after which it is attached to the wooden base with nails in increments of 15 mm.
3. A patch of roofing material is placed over the cut, each side of which is larger than 50 mm of the damaged area. The new element is glued onto the same mastic and nailed into place. A layer of mastic is applied over the fastener heads and along the edges.

If your garage roof is swollen, a patch is needed.

Replacing a large piece of roofing

Repairs are carried out using the same algorithm as for swelling, but in this case all layers of the coating are cut out to the base. There will be as many patches as the number of layers of old material that were removed. Each part is attached to the base using mastic, and after the finishing element is glued, it is necessary to nail the thickness of the entire rectangle.

During routine repairs, it is possible to correct minor damage in several places, but overhaul involves a complete replacement of the waterproofing layer, sealing all seams and joints. In some cases, the installation additional systems, for example, ventilation, installation of insulation, changing the angle of the roof.

Sometimes covering a garage requires partial replacement

What manufacturers of building materials offer for roofing repair work

In addition to the materials traditionally used for garage roof construction, there are many options that are not inferior in quality and ease of installation.

Flexible roofing from Technonikol for garage renovation

TechnoNIKOL is a supplier of various types of building materials, including finishing coat for the roof. This roof has a unique structure - it is made of a layer of fiberglass or polyester, coated on all sides with a bitumen composition. To enhance resistance to mechanical, atmospheric and other factors, the coating is covered with basalt chips on top. The Technonikol sheets have a self-adhesive surface on the bottom, which is protected by film.

The ability to choose any color adds a bonus in favor of choosing a product from this manufacturer. A garage decorated with such material will not only be well protected from precipitation, but will also attract attention.

TechnoNIKOL has many advantages

You can use any TechnoNIKOL roofing to install the roof:

• soft tiles;
• rolls of overlay coating.

Despite the small range of roofing products, Technonikol is becoming popular among car owners quite quickly. It not only repeats the properties traditional materials, used to repair roofs, but also improves them many times over. This finishing coating is suitable for both partial replacement of deformed areas and major dismantling.

Why do people choose TechnoNIKOL, leaving behind years-proven installation methods? Its main advantages:

1. Ability to withstand high and low temperatures. The roof can withstand exposure to both +50 degrees and -60 degrees.
2. The impeccability of the waterproofing layer - even the longest rainfalls or abundant melting of the snow cover will not break the tightness of the structure.
3. No corrosion processes. The composition does not rot, rust, or oxidize, regardless of the level of humidity.
4. High resistance to wind and mechanical loads. Such a roof will last through a strong hurricane, large hail, and falling trees and branches.
5. Easy to use and installation. To repair a garage, all you need is the desire and a minimum set of tools; no additional equipment or special skills are needed.
6. Focused pricing policy on people with any budget. For those who want to save money without sacrificing quality and for those who like to get something more than just a roofing covering by paying a little extra for it, a suitable brand will be selected.

Roofing from Technonikol has waterproofing properties

Like any material, TechnoNIKOL is not without its drawbacks. In this case, there is only one - laying the roofing layer is allowed only on top of a solid base. To fulfill this requirement, you will have to spend a little money - collect pitched roof and purchase plywood for its entire area.

Laying process

Installation of the finishing layer is carried out depending on what material will be used. It can be laid by fusing the coating or attaching it to fasteners. In the first case, the work is carried out on a flat roof, when the rolls are rolled out over the entire surface of the garage, heated with a burner and glued due to the melted structure. If we are talking about inclined structures, then a suitable method would be to fasten the material with self-tapping screws, nails, and even staples from a construction stapler.

Any type of installation requires careful preparation of the base. So, the surface must be smooth, clean and dry.

The manufacturer warns that any repair work using Technonikol is allowed only in dry weather. If there is rain or fog outside, the material will soon begin to bubble. Favorable temperatures range from +7 to +26 degrees, that is, installation is best done in spring or early autumn.

As a rule, there are no difficulties when laying TechnoNIKOL soft covering, but all work requires a clear sequence and the use of only recommended additional elements.

As a vapor barrier layer responsible for maintaining the temperature balance and humidity level in the room, it is recommended to use a special TechnoNIKOL film with a three-layer structure. The ease of use of this high-strength fabric also lies in the fact that it fits perfectly on any base, including untreated surfaces. It is advisable to cover pitched structures with a membrane, and flat roofs with perforated or non-perforated film.

Soft roofing consists of several layers

Since tiles from different packages may have slight color differences, it is better to mix the sheets together in advance to ensure uniformity of the palette. The protective film on the bottom of the covering must remain intact until the element is laid.

The stages of roof installation are as follows:

Following the advice of professionals, you can lay rows from the middle of the pitched structure.

Depending on how tilted flat roof, the number of layers of material to be laid is determined. For significant slopes, a two-layer application is sufficient, small angles need more strengthening.

There are several installation methods roll covering

Installation is carried out in stages:

The material must be protected from exposure to high temperatures, since the process of melting the protective film may begin, and it is almost impossible to peel it off from the material.

Impeccable waterproofing of the garage roof using Bikrost

Thanks to unique composition Based on fiberglass and binders with adhesive bitumen, Bikrost flawlessly copes with the waterproofing of roofing structures.

The material is laid according to the following scheme:

1. The roof is cleared of leaves, branches and other debris and primed well.
2. The rolled sheet is gradually rolled out and heated by a burner. Vulnerable areas - corners and edges - should be thoroughly heated. The canvas should be immediately pressed tightly to the base.
3. For a high-quality connection, the material is overlapped by 7–10 cm.

You need to install Bikrost carefully but quickly, since its bitumen base can set in a few minutes. In general, the process is similar to laying roofing felt, but there is no need to waste time heating the resin and rubbing it on the roof.

Bikrost is a popular roofing material

When using Bikrost as the main roofing material, it is important to consider a number of factors:

1. It does an excellent job of protecting the roof if the structure has a slight slope. If the angle of inclination is 15 degrees or less, then it is recommended to roll out the sheets perpendicular to the slope; if the roof slope is greater than the indicated parameters, then parallel installation would be advisable.
2. When covering a roof for the first time, a two-layer application is required, with the first layer being a material with a double-sided polymer film coating, for example, the KhPP brand, and the second is a roll treated on top with large grains of topping (KhKP brand).
3. The ideal option would be to fuse the material using a torch, but in the absence of of this instrument You can use bitumen mastic.

Is it possible to repair a garage roof in winter and how to do it correctly

In winter, due to weather changes, extreme conditions for any external work, therefore repair of old roofing is carried out only in exceptional cases. Heated bitumen compositions, suitable for the warm period, are replaced with cold mastic, more suitable for severe frosts. It is offered in liquid form in containers of various sizes, does not require any preparatory manipulations and is immediately ready for use. To some extent, cold weather simplifies the process, since there is no need to heat the bitumen or resin mass over a fire.

In winter, repair work is carried out only as a last resort.

The master's primary task is to make the maximum amount of effort to secure the new coating over the old one. So, in places of damage, you should thoroughly clean the dirt, remove debris, and dry the surface with a hairdryer. All swelling, folds and other defects are cut crosswise with a knife. The old mastic should be removed from under the layer of material and everything should be dried. The treated elements are lubricated with fresh mass and pressed against the roof with force. A patch of a material of a similar composition with a preliminary coating of mastic is applied over the slot.

In this way, all imperfect areas of the roof surface are repaired. In places where the roof is torn, mastic is poured over the entire damaged part, followed by a new piece of roofing layer.

The formation of roof leaks some time after rain indicates the absence of specific damage, this means that the roof is completely covered with cracks, which gradually allow moisture to pass through. Then patching equipment will not help; a major replacement of the roof is necessary.

Detailed description repairing the garage roof will make the work much easier, but if serious difficulties arise, you should not experiment, but rather contact specialists, which will help you avoid extra costs in case of poor quality coating.
