How to patch a garage roof. Rules for major repairs of a garage roof: advice from experienced craftsmen. Working with profiled decking when completely replacing the covering

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 day. short term.

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 effect weather conditions;
  • bad ecology;
  • non-compliance with stages roofing works;
  • 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 under roofing;
  • 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 the height of the room acceptable for installation work and the small size of the roof itself.

It all starts with determining the scale of the upcoming repair and the necessary materials. Depending on the degree of damage old roof repairs can be partial, when individual deformed parts are replaced, or major, when complete dismantling designs. You can cover the roof 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

Performance overhaul It is recommended to plan 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. Thanks to its small size garage space 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

During major renovations, 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 coverings is 100 rubles, the choice is more cheap 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 the right 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 heavy weight and fragility.


Slate is both durable and fragile material

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

  1. Initially, a sheathing and a lining layer of roofing material are installed to insulate 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 use special nails with sealing gasket.

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 inspect 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 installation technology of the structure or a very long period of 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 repair work, the result will please you for many years. Concrete structure not susceptible to deformation high pressure snow masses, has impeccable waterproofing.

Repair concrete roof garage is carried out in stages:


As a roofing covering for a concrete roof, you can use roofing material or waterproofing. Liquid rubber is in great demand as an alternative material.


Liquid rubber is an 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. Also, bitumen retains heat well, so it can be used as thermal insulation material, and provides a sufficient level of noise 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 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. The inner surface of the cut material is covered with cold mastic on both sides, after which it is attached to the wooden base with nails in 15 mm increments.
  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 the garage cover 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, among which there is a finishing coating 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. Orientation pricing policy for 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 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.

Difficulties during installation soft covering“TechnoNIKOL”, as a rule, does not exist, but all work requires a clear sequence and the use of only recommended additional elements.

It is recommended to use as a vapor barrier layer responsible for maintaining the temperature balance and humidity level in the room. special film"TechnoNIKOL" 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 roof- 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 inclined the flat roof is, the number of layers of material to be laid is determined. For significant slopes, a two-layer application is sufficient; small corners require more reinforcement.


There are several installation methods roll covering

Installation is carried out in stages:


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

Impeccable waterproofing of the garage roof using Bikrost

Thanks to a 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 it 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 if this tool is not available, 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 when serious difficulties You shouldn’t experiment, but it’s better to turn to specialists, which will help you avoid extra costs in case of poor quality coating.

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 ones, but at the same time durable materials– ondulin, flexible tiles, profile flooring.

Regardless of the restoration technique chosen, it will be necessary to thoroughly prepare the roof for repair activities: examine the roof, determine its level of wear, determine roofing elements, needing 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. Such problem areas must be dealt with 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 poured over the entire soft roof or exclusively 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 terms, the technology for roof restoration using roofing felt 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 felt.

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);
  • The underside of the bicrost is heated by a gas unit;
  • 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 a garage with your own hands, use universal self-tapping screws with a special rubber gasket. Such gaskets can be made independently or purchased separately from 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.

The garage roof is most often a flat or low-slope single-pitched roofing structure, which often suffers from leaks, stagnation of water and disruption of the waterproofing coating by gusts of wind. Therefore, it needs regular maintenance and periodic restoration. It seems to an inexperienced craftsman that only a professional can do this task, however, using modern roofing materials, it is quite possible to repair the garage roof yourself. In this article we will tell you how to inexpensively restore the tightness of the roof by using roofing felt, mastic or corrugated sheeting.

The garage roof has special properties due to the small slope of the slopes, due to which it is more susceptible to leaks and damage than steeply sloped gable structures. Standard materials for the construction of outbuildings are roofing felt, corrugated sheets, slate, that is, products that are inexpensive but have a long service life. Garage roof repair is necessary if the following defects are found on its surface:

  • Cracks. Ruberoid, mastic and membrane roofing, after several repetitions of freezing and thawing cycles, become covered with cracks through which moisture and cold air can leak.
  • Roofing sheet failures. As a result of strong wind loads, roofing materials can be torn off the roof sheathing, exposing rafter system structures, as a result of which the insulation and wooden frame elements become wet.
  • Mechanical damage. Impact from branches, stones, debris, impact snow load lead to damage to the integrity of the garage roof. This entails leaks and deformation of the structure.

Important! The roof structure serves as the first protective barrier between a person’s home and the external environment, which sometimes behaves aggressively. Roofing felt, corrugated sheets, slate and bitumen mastic are reliable, but not eternal materials, so garage roof repairs are carried out once every 2-3 seasons.

Types of repairs

If the roof structure has lost its tightness, you need to repair the garage roof yourself. Typically, this operation is performed once a season after a regular autumn inspection of the condition of the stingrays. After conducting a detailed inspection of the roof, you can assess the condition of the roof. waterproofing materials, and choose what type of restoration is required:

  1. Spot. If small cracks, pockets of rust and other isolated damage are found on the surface of the garage roof, then it requires spot repair. Roofing felt can be patched up with patches, and cracks can be covered with mastic.
  2. Partial. If the damage is more extensive, the roof is restored using partial repairs. The damaged upper layers of the roofing pie are removed, and new waterproofing materials are laid in their place - roofing felt, roofing membranes, corrugated sheets or ondulin.
  3. Full. If the garage roof is in poor condition, then only a complete reconstruction can restore its tightness. To do this, the roof covering is completely dismantled and the frame is covered with a new roofing pie.

Many don't experienced craftsmen wondering how to repair a garage roof on your own at a minimum cost. However, experienced roofers claim that spot and partial renovation It is advisable if the area of ​​damage does not exceed 15-25% of the roof area.

Repair sequence

Modern roofing materials, which are light in weight and have high waterproofing ability, make it possible to repair a garage roof without dismantling the old coating. But to restore the waterproofing layer, it is important that the roof rafter frame maintains its integrity and high load-bearing capacity. To ensure that the results of garage roof repairs are satisfactory and have a lasting effect, reconstruction roofing structure performed in the following sequence:

  • Need to check condition rafter frame. On wooden elements The structure should be free of mold and rot. If defects are found, they need to be eliminated: broken rafters replaced, deformed areas strengthened. It will not be superfluous to treat the frame with an antiseptic composition.
  • Then the roof covering should be removed partially or completely. If roofing material was used to cover the garage roof, then only the top layers can be removed. If there are no swellings or bubbles on the roof surface, then the old coating can be left as a lining, and a new waterproofing material can be laid on it.
  • The roof surface must be cleaned of debris, dust and dirt. To improve adhesion between the old and new coatings, you need to degrease the roofing.
  • After all manipulations, the roof must be thoroughly dried. This requires 24-18 hours; you can speed up the procedure using an industrial hair dryer.

Note! Careful preparation of the surface for work is the key to the effectiveness and sustainability of the results of the repair. We remind you that it is possible to reconstruct the roof using roofing felt or roofing membrane without dismantling the old covering only if there are no bulges, bubbles or other severe damage on it.

Materials

When deciding how best to cover a garage roof, experienced craftsmen pay attention to inexpensive but proven waterproofing materials that have a long service life. Ruberoid, corrugated sheets, slate, and various roofing membranes are perfect for garage roofing. The lighter and stronger the coating, the longer it will retain its performance. Most often used for repairs:


Please note that the choice of roofing depends on the angle of inclination roof slopes, the number of stingrays, as well as climatic conditions in the construction zone. Single-pitched and flat roofs are covered with roofing felt or roofing membranes, single-pitched roofs with ondulin, and gable roofs with .

Video instruction

Repairing a garage roof with your own hands is not so difficult if you use high-quality material and carry out the work strictly following the technology. Over time, the garage roof, like any other, becomes unusable, and therefore repairs have to be made. It should begin with determining the level of wear of the entire structure and coating. However, first it should be noted that roofing can be of two types: hard and soft. The financial costs of repairing a garage roof will directly depend on your wishes and the type of roof you choose. Let's look at the technology for carrying out repair work for the most popular types roofing materials.

Covering with roll roofing materials

Repair of a soft garage roof is usually carried out in several layers. This covering is called roofing. Its top layer consists of a covering material that has a refractory bitumen layer with a special coating. This topping can be fine-grained, coarse-grained (scaly) or dusty.

All rolled roofing materials are divided into basic and non-basic. Baseless roll materials are produced by rolling a mixture that consists of an organic binder, various additives and fillers. The base of the roof is always treated with bitumen, tar or a mixture of both.

Main property roll material is waterproof. In addition, it is also quite tensile strength, heat resistant and flexible. A garage roof made of rolled material, as a rule, should have five layers. This also includes glassine and roofing felt. All layers are glued to the surface using bitumen mastic.

Quite often, roofing material is fused onto the roof using a gas burner. A roof covered with a binder bitumen component provides a service guarantee of at least 7 years. Such a short period is primarily associated with the fragility of the bitumen layer at low temperatures and increased aging under the influence of ultraviolet radiation.

Roll material is often used for coating flat roofs or roofs with a small slope angle. It is also used to cover the roofs of high-rise buildings.

Many garage owners have a question: how to repair it if it leaks? Roof repair is quite simple and is carried out by fusing a small layer of waterproofing. This layer is usually laid on moisture-proof plywood or OSB board. To cover a garage roof with your own hands you won’t need much:

  • perform complete or partial dismantling of the roofing base;
  • lay down new material, or replace defective areas;
  • Lubricate the inside of the pothole with mastic and apply a patch of roofing material;
  • Treat the repair area with putty.

For a piece quality repairs garage roof should:

  • cut places that fill with water with an “envelope”, i.e. cut and unfold corners;
  • completely remove water, dry the defect area, and clean it from dirt;
  • completely cover the surface with mastic, and put the corners of the envelope back and press tightly;
  • a piece of material prepared in advance is placed as a patch inside the hole;
  • Apply a patch on top, and apply a layer of mastic on top with a hard brush, smooth and level the material;
  • the edges of the old roofing material are folded back and then pressed tightly to the surface with lubricated mastic;
  • For reliability, the top of the patch is lubricated with an additional layer of mastic.

Very often, when repairing a garage roof, you have to work with hot materials, and therefore it is important to observe fire safety.

Organization of laying works

Carrying out repair work on the roof of a garage requires the use of only high-quality roofing felt, which does not have any flaws in its structure. However, if these are already present on the purchased material, then the defective part will need to be cut off and smaller strips laid on the roof.

In order for the garage roof to last longer, you should purchase not only good material, but also to correctly construct the base for it and strictly follow the installation technology. Maintenance and repair of soft roofs is recommended every 4-5 years.

For such roofing material you will need resin, which is prepared in a tin bucket. It is melted over the fire until it becomes thick sour cream. After the roof is filled with resin, the first sheet is laid and compacted, the next one is laid overlapping. The first layer of roofing felt should dry for 12 hours, then proceed to laying the next layer. In this case, the joints of adjacent layers should not coincide, this will make it possible to prevent moisture from getting between the layers. You should pay very close attention to places where there is an abutment to neighboring structures.

Self-repair of a garage roof can be performed using several technologies. The specific decision on how to restore the roof is made depending on design features garage, the type of roof above it and the degree of wear and tear of the roofing material.

Repair methods and preparation for it

Repairing a garage roof with your own hands is carried out in several ways, using as a covering soft materials, hot bitumen, tiles or corrugated sheets. Very often you can see garage roofs covered with inexpensive but durable materials such as ondulin or flexible tiles.

  • Using a metal hook and rope, lift the bucket of molten bitumen onto the roof.
  • Damaged areas are poured with hot material. You can use a board to direct the bitumen stream to the desired location.


During the pouring process, special attention should be paid to the areas where preliminary cuts were made; these places should be filled as much as possible. Only in this case maximum protection of the garage from seasonal precipitation is ensured. Using molten bitumen, you can restore the entire roof or individual sections.

Garage roof repair with bicrost and roofing felt

Roofing felt has been used for roof repairs for a very long time. It is enough to treat it with bitumen mastic and lay it on the damaged areas.

The roof repair scheme with roofing felt is as follows:

  • The material is cut into pieces of the required geometric shape.
  • Cuts are made into the coating to expose the surface underneath the damaged area.
  • Mastic is poured into this hole. Mastic for roofing felt from various manufacturers can be used. It is also possible to use molten resin.
  • Cover the damaged area with roofing felt and fill it with mastic.
  • The bent edges of the hole are closed, and an additional piece of roofing felt is placed on top.
  • Fill the entire repaired area with bitumen mastic.


If you plan to completely replace the roofing felt on the roof, then you need to fill the entire area with tar. Naturally, before you fill the garage roof, you need to carefully plan and calculate everything. Strips of roofing felt are laid on top of it with an overlap of up to 15 cm. To prevent the tar from hardening, it is poured in small portions. In this case, you can, without haste, restore the entire roof in separate areas.

When bubbles appear on the surface of the roofing material, perform the following actions: the swollen areas are cut with a knife and pressed tightly to the plane of the roof. An additional layer of tar is poured on top of this area.

For maximum protection of the garage from precipitation, roofing felt is laid in two layers. This option will be reliable protection garage from precipitation.

Another answer to the question of how to repair a soft roof on a garage is the use of the popular bicrost material. Laying the material does not require the purchase of tar or mastic; for work you will need a gas burner.

  • Roll out the material to a short length.
  • Heat the roll from the reverse side.
  • Spread the heated area on the surface and press it, rubbing it with a T-shaped stick.
  • Stand with your feet on the bedded area and roll out the material again. Repeat the steps with heating and grinding.

Each subsequent strip of bikrost is laid with an overlap of up to 10 cm. Restoring a roof with bikrost is more expensive than repairs using bitumen or roofing felt. However, the installation process in the first case is simpler, faster and with minimal labor costs.

How to repair a hard type roof with your own hands

Repairing a garage roof with corrugated sheets or metal tiles also does not seem difficult. In this case, it is enough to replace the damaged sheet, which is quite simple to do. Difficulties may arise when completely replacing a hard roof, due to high cost roofing materials of this type.

Installation of metal tiles starts from the bottom and proceeds towards the top. The sheets are fixed using self-tapping screws with a special rubber gasket. As a last resort, you can use ordinary self-tapping screws and make the gasket yourself or buy it at a hardware store. At the top and bottom of the metal tile sheet there are special latches that are designed for overlapping sheet installation.


Restoration of a roof made of corrugated sheets is considered more difficult. In this case, the problem of how to repair a garage roof can be solved using the following tools: a tape measure, a circular saw and a screwdriver.

Work must be performed in accordance with specific instructions:

  • The first sheet is laid in any corner of the upper part of the roof and lightly secured with a screw.
  • Two more products are being installed.
  • Check the coincidence of the sheets with the line of the roofing ridge. If necessary, then align the laid elements.
  • Perform major fixation of corrugated sheeting. In the middle of the profiled sheet, fasteners should be located in a checkerboard pattern, and in the upper and lower parts - in every second wave.
