The construction of a metal garage, in comparison with a brick structure, has more advantages. The main one is the simplicity and speed of manufacturing. The article invites you to get acquainted with how the repair of metal garages is carried out.
Before starting construction, the future owner must choose the material for the construction of the structure.
A garage made of metal structures, like any structure, requires repair over time. Particular attention should be paid to the repair of its roof.
Tip: If you find any problems on the roof, they should be repaired as soon as possible. The safety of the car and the items stored in the garage depends on this. Repair should be started at a constant positive temperature.
Leaks in a previously dry roof may indicate breakage of the roofing metal sheets. In this case, the device of a folded roof made of galvanized sheet will make it possible to get rid of major repairs for almost 50 years, and only make cosmetic updates.
A budget option for roof repairs is to paint the roof with "rubber" paint, which significantly reduces the impact of the environment. A layer of acrylic paint will prevent condensation from collecting on the ceiling.
Roll roofing materials are often used to repair the roof of any garage.
When using roofing material, as shown in the photo, the structure will be multi-layer, representing a roof, the top layer of which consists of:
The bottom layer of the roof is made of uncovered material.
A video will show in more detail about the installation of roll materials on a metal roof.
The most common nuisance for a metal garage is associated with the harmful effects of moisture on unpainted places.
It is better to replace a sheet that is rusted, but to save money and if you have a welding machine, you can try this technique:
Tip: When applying a layer of polystyrene foam with a thickness of ten centimeters, its soundproofing indicator is comparable to a two-row brick wall 40 centimeters thick.
The formation of condensation droplets (see Condensation in a garage, what to do?) On a well-sealed metal garage primarily indicates poor air exchange. The optimal ratio of the extracted and supplied air should be 1: 6. Standard ventilation holes do not provide a stable supply of fresh air.
Tip: In this case, when carrying out repairs, the existing ventilation system should be improved.
A metal garage is a lightweight construction that requires a purely symbolic foundation arrangement according to one of the options:
VIDEO
Tip: When making a foundation, it should be poured all at once to create a single monolith of the structure.
The subsequent repair depends on the type of foundation. If there are potholes or cracks in the base, it is better to make a new screed over the entire surface.
What kind of metal garage structure is better, how to properly repair the structure, the video will show in detail.
For a man, a garage is practically a home. It is also a "hobby club" and a place where the opportunity to show skill is accompanied by the work of engineering. The owner is solely responsible for rearranging and cleaning the garage. He often repairs himself, because it is undesirable to trust strangers to restore all categories of order in your favorite possessions.
In addition, the process of restoring the technical condition of an adored property sometimes brings real pleasure and increases self-esteem. An independent repair of the roof of the garage roof is quite available to the home craftsman, if he is armed with information on how to perform it.
The roof of buildings of any type, size and purpose tends to wear out, to the great regret of the owners. Heavy gusts of wind, hail, torrential rains, birds, abandoned stones and suddenly fallen trees regularly check it for strength. Similar factors with equal constancy attack the roofs of garages, which sometimes do not cause as much concern to owners as a leaking ceiling in an apartment. Because of absolutely unjustified frivolity, the beloved "iron horse" or "swallow", slowly rusting from an excess of moisture, suffers not like a child.
Leaks are a clear indicator of a violation of the integrity of the roof or flaws in the construction of the roofing pie. However, you should not wait for the appearance of smudges on the walls and ceiling. In order not to face serious facts that require expensive repairs, it is necessary to carry out preventive inspections of the upper garage ceiling from the outside at regular intervals 4 times a year and monitor the condition of the ceiling daily.
Garage roofs, like the buildings they cover, are a term that combines a wide range of structural varieties. They are erected over standard free-standing boxes, and over lined up garage boxes, and over household structures of vast private estates. They are single and gable, hipped, mansard, etc. They can be equipped with any of the existing types of roofing materials, the choice of which depends on the status and financial capabilities of the owners.
Regardless of the cost of the material used in the arrangement, the repair of the garage roof is the inevitable result of its service. Of course, the more resistant the coating is to destructive factors, which is almost always directly related to the price, the less often it will be necessary to restore its technical perfection. True, durability rarely coincides with the ability to lay and repair it yourself. Therefore, adherents of soft coatings predominate in the ranks of independent owners of car houses, and most often they are used in construction and repair:
Bituminous-polymer descendants of roofing material for the repair of single-pitched garage roofs made of reinforced concrete panels.
Elastic vulcanized membrane with EPDM markings, popularly known as “rubber roofing”. It is used in the repair of similar low-pitched roofs.
Flexible shingles, which are figuredly cut pieces of bitumen-polymer material used in the arrangement and repair of gable, hip and mansard roofs with slopes from 11º.
In the vastness of the fatherland, they are rarely carried away with bituminous tiles, although this is a quite promising and easily repaired type of coating. It is mainly used when it is required by the aesthetic culture of decorating the estate, made in a single stylistic spirit.
Let us mention that in the field of arranging garage roofs, slate, ceramics, profiled sheets and metal tiles are used. They are much less in demand, and most often they require professional repair. Therefore, we will pay attention to the most common soft options and methods of their restoration.
Damage typical for soft roofing includes punctures, breaks, bulges, creeping of the coating, depressurization of joints and zones of abutment to adjacent walls or to the parapet. Not all of the listed reasons are accompanied by leaks, but, nevertheless, need to be eliminated. According to the degree of application of efforts and costs, repairs are divided into two types:
Ongoing correction of coating defects. The current repair consists in correcting small single damage and minor flaws in the construction, if the total area of the repaired surface is approximately 10% of the roof area.Roof overhaul. It consists in a complete replacement of the damaged coating, performed when 60% of the damaged roof area is found.There is a noticeable interval between the indicated percentages, which makes it possible for the owner, in fact, to give preference to one or another repair type. He himself will be able to decide what is more profitable, endlessly patch up the gaps, or lay a brand new coating.
Ongoing repair operations involve pinpoint repair of damage. But during the overhaul of the garage roof, the waterproofing carpet is often completely changed, the abutments and joints are again sealed, the drainage funnels, if any, are sealed. You can also change the slope of the slopes, install additional ventilation elements or insulate the roof. However, before making major design changes, you should consult with the designers.
It is especially worthwhile to treat the installation of thermal insulation. It will, of course, reduce heating bills if the car house is heated autonomously. If you have to repair the usual compartment of a long garage complex with a common heating network without heat meters, there is no point in adjusting and saving the supplied energy.
Again, roof insulation can lead to a violation of the temperature regime of car storage. Indeed, according to the clear requirements of SNiP II-93-74, the thermometer scale in the garage should not show above + 5 ° C. In order for the conditions of the car's maintenance to meet the regulated standards, accurate calculations are needed. Otherwise, condensation will appear in the thermal insulation, and its drops will "sharpen" the outer seams and the paintwork of the body all year round.
We will concentrate on the elementary replacement of the coating that meets the efforts of the home craftsman and his level of craftsmanship.
Roof overhaul is carried out in the warm season. It is recommended that the restoration processes be timed to the period with minimal precipitation. Only in case of emergency is it permissible to carry out work in cold and rainy times with the obligatory installation of an awning over the site being repaired. The scope of work on the roofs of private garages is usually small, but it is advisable to complete all operations in one day.As a last resort, on the first day of repair, the roof waterproofing should be completely arranged.
Typical work sequence for a complete replacement of the coating:
Repairs may only be carried out at the temperature conditions specified by the manufacturer of the material. Do not work with coatings if the thermometer shows a value below the limit of its frost resistance. In case of an urgent need to carry out laying with minus readings, the material is preliminarily laid in a heated room. The temperature of its adaptation is from 15º to 20ºС, the holding time is not less than 4 hours.
Let's start by preparing the foundation. Removing minor potholes and cracks will not require a significant period of time or much effort. Worse, if the surface of the reinforced concrete floor has noticeably crumbled, if the boards or slabs of solid flooring are rotten. Such troubles require either pouring a cement screed, or installing a new prefabricated base.
We will assume that the laborious process of complete restoration of the base is not our lot. Then we will find out if its moisture allows you to start laying bitumen-polymer waterproofing. The restrictions specified in SNiP 3.04.01-87 allow starting work if the humidity does not exceed 4-5%. Without a device, literally "by eye", it is impossible to determine the exact parameters of humidity, but there are folk methods, these are:
A small spill of bitumen heated to almost boiling to the surface. If the bitumen starts to bubble, the moisture content is higher than the established norm.
Laying a piece of polyethylene on the base with a side size of up to a meter. The edges should be fixed around the perimeter with adhesive tape.
If condensation accumulates on the inner surface of the polyethylene, the base must be dried. Close the base section until noon, check in a day.
You can not resort to folk methods of testing if the old roof does not upset with swelling. The base can then be primed immediately with a bituminous primer to optimize the adhesion to the waterproofing overlaid, then:
Upon completion of the laying of the coating, metal parts are installed: aprons, fastening strips to parapets and vertical walls, etc.
The quality of the connection of the coating sheets into a single web is judged by the outflow of the binder along the side edge. The width of this protrusion over the edge is 5-15 mm. After laying the next strip, the outflow on the previous element must be carefully trimmed with a spatula. Poor-quality seams with peeling strips are difficult to repair using a torch. It will be more convenient to warm up the defective place with a building hairdryer with a flattened nozzle.
If the flat top floor does not have parapets, then before you start repairing the garage roof with your own hands, a cornice bar should be nailed along the perimeter or where possible. It is needed for the subsequent fastening of the metal strip and for the decoration of the roof edge.
It is possible to repair the roof with bitumen and bitumen-polymer rolls without removing the old roofing material or similar material, if it was soundly repaired during the current repair, and even with the application of a 2-meter lath, recesses more than 5 mm were not detected.
All currently existing types of roofing membranes are suitable for roof repair. However, for a garage, a membrane with an EPDM marking is considered the most acceptable. The material is absolutely indifferent to the neighborhood of the old membrane and the bituminous coating, it is very resistant to atmospheric attacks. And another plus: it is wide, thanks to which the garage roof can be covered with a single piece without seams.
Algorithm for repairing a garage roof with EPDM installation:
At the end, we put in place the cornice strips, elements of the drainage system and aprons.
If it was not possible to do without butt seams, we glue the EPDM panels with an adhesive with a synthetic rubber base. The above compositions cannot be used to form the seams of the material.
Owners of garages with passages through the roof of communications and with abutments to walls or parapets will need to glue additional layers of reinforcement on top of the coating. Reinforcement carpets around drainage funnels, aerators, pipes are rounded. The size is calculated so that the edge of the reinforcement recedes from the edge of the hole by 20-25 cm. Along the abutment line, the reinforcing pad is applied with strips of self-adhesive membrane so that half of the strip falls on the vertical plane and half on the horizontal.
It is also better to completely replace worn-out bituminous shingles. Especially if you forgot to stock up on the material of the batch that was used in the initial arrangement. The sequence of actions for replacing bituminous tiles resembles the process of repairing a garage roof with roofing felt or a modernized bitumen-polymer coating. The difference is that the shingles are stacked and attached individually. They are not fused, but glued to mastic and fixed with brushed nails or self-tapping screws.
You should be very careful about dismantling work, because unspoiled elements of the coating can be used later. Nails must be carefully pulled out with a nail driver so as not to damage the crate and not provide yourself with additional work on the construction of a new base. After removing the old coating, waterproofing and fasteners, the surface is thoroughly cleaned. Then the reinforcing carpet is laid down again and the covering is laid.
Finally, to refresh the memory of the principle of the simplest repair of the roof of the garage roof with bitumen roll material will help the video:

Garage roof repair. Types of roofs and roofing materials. Flat and inclined single-slope structures. Solid roofing materials
It is useful to learn how to make repairs to the garage roof with your own hands, or you will have to call for help from specialists whose services you need to pay for. And I must say, it costs a lot of money, if, of course, you are dealing with professionals.
Any person who owns a country house, summer cottage or just the aforementioned garage can face a roof repair - sooner or later the roof may leak, and if measures are not taken in time, the room will begin to leak. Therefore, we suggest that you understand the main roofing materials, methods of their installation, as well as the possibility of cases of local replacement of the coating.
Repair of the iron roof of the gable roof
Note. In small architectural structures - small houses, cottages, summer cottages and garages, gable or pitched roofs are usually made, although you can also find structures of the hip or four-pitched type.
Types of roofs for summer cottages and country houses
You may need the following types of repairs:
filling the damaged area with hot tar to create the tightness of the coating;installation of a patch made of soft roofing materials , for example, on top of the old roofing material in a certain area, you can lay several strips of new material, but it is also sometimes fixed with resin;replacement of solid roofing materials in a specific area : slate, corrugated board, tiles;in addition, it can be repair of a seam roof , which is already somewhat more difficult and requires certain skills of a tinsmith.Much also depends on the structural features of the building:
for example, if this is a collective garage, then in most cases, these are soft materials on a bitumen basis (the same roofing material), since no one will cover their part of the building with more expensive material;
but if it is a separate garage, cottage, cottage or house, then more durable materials of a solid type are already used, the same slate, corrugated board or tiles of different kinds (ceramic, metal, bituminous);
the treatment of the roof with hot tar for sealing is usually done only on sloped or flat roofs - on gable and complex structures, the impermeability of the coating is achieved due to the overlap of the roofing elements on top of each other.
Sealing point damage
Even if you fix the leaks yourself, an estimate for roof repairs will not hurt you. So you can not only determine what materials you need, but also buy them in advance so that no force majeure circumstances arise during work.
Climb up and walk along the roof, identifying visually damaged places - it is not difficult to do this, since these are ordinary ruptures or holes in the roofing material. If there are not very many of them, then you do not have to cover the entire roof or its separate section - you can just get by with small patches.
Fill the damaged area with tar
At the place of damage, cut the roofing material in the form of an envelope to make four triangles, and bend them along the sides to clean out the debris that got inside. Then pour melted tar into it.
Next, lower the triangles back, and from above you also fill this place with resin so that the seams are not visible (as in the top photo). If the hole was large, then additionally glue a piece of roofing material on top and also cover it with resin.
Recommendation. If you need to patch one or two damage, then you don't need a lot of resin for that.
It is very easy to repair and build a roof on a flat roof with roofing felt. To do this, you will need a certain number of rolls (it must be calculated for the covered area) and tar. However, it is already better to melt it on the ground, and then lift it in a bucket with a rope.
First, remove all debris from the roof, including the old coating if it is torn. Then pour melted tar in sections, so that there is enough for the width of the roll or for two widths, if possible.
Next, simply roll out the rolls on the roof so that they overlap each other, that is, they overlap. And the joints must be covered with resin to prevent precipitation from flowing.
Installation of hardfaced soft coating
Nowadays, there is a worthy replacement for roofing material - these are soft deposited coatings on a bitumen basis, the strength of which is much higher. Consequently, when using them, the service life of the structure is significantly increased.
They have several layers and can be made on the basis of:
The material is glued to the sub-base with bitumen when heated, as shown in the top photo. Such coatings may differ from each other, but the milestones at the bottom of them have a fusible film intended for installation (for gluing) - sometimes it can be sprinkled with quartz sand.
The quality of such coatings mostly depends on the mixture of bitumen with polymers - this layer is located in the middle of the sheet, between its protective, top layer and the base - the fusible film, which was discussed above. The mixture may differ slightly in its composition, since it can be oxidized bitumen, as well as the same bitumen, but already with the addition of polymers.
You will understand the difference right away - firstly, if there are no polymers, then the cost of the material is much lower, and, secondly, during operation it is not able to retain heat, and also loses its elasticity at low temperatures.
Note. One of the worst enemies of soft surfaces is precipitation in the form of snow.
Replacing a broken slate with a new one
But to repair the roof of a summer cottage, house or cottage, most likely, you will need solid roofing materials. If this is slate, then you are very lucky - it is very easy to replace it, unlike a seam covering.
In order to replace one slate, you first need to remove it. And for this you have to “disturb all the sheets that adjoin it, that is, overlapping it and located under its edge. At least these are three sheets - the top, bottom and one of the side ones, which is on top and covers the neighboring overlap with its wave.
The most important thing in this case is to carefully remove the nails so as not to damage the good (whole) material. And it is sometimes very difficult to perform such an operation, since the nails are rusty, and you will simply have nowhere to rest with a nail puller.
Therefore, the most convenient option in such situations is to cut off the nail heads with a grinder, if you have the opportunity to pull it out onto the roof by connecting it through an extension cord. The nails left without heads can subsequently be simply bent under the wave, resting against them with something flat, for example, a chisel or an old chisel (just hammer a new nail nearby - this will not cause any problems).
Note. We do not even mention the replacement of materials such as metal tiles or corrugated board, since they practically do not need to be replaced.
So, if your roof is covered with sheet metal and you need to repair the roof of a cottage (house, summer cottage, garage), then everything is much more complicated here, since you have to unclench the folds in order to dismantle the old covering. And then compress them again.
Unclenching the fold is also not easy, perhaps even more difficult than rolling it up. The fact is that this will have to be done carefully, with a chisel, in order to then level the edge of the strip remaining on the roof for further use.
As a rule, a complex tool is not needed here - such a strip is leveled with two hammers. In addition, for replacement, it is very important to correctly measure the dimensions of the sheet so that it fits right into the seat - otherwise, its roll-up will be of poor quality.
Repair of a galvanized roof - the seam is rolled up with a roof frame
There are three main types of folds:
recumbent;
standing corner (L-shaped);
just standing.
So for roofing work, as a rule, the third, standing version of the castle is used. It is strong enough, tough and will not let moisture through either from the rain or from the melting snow mass.
Therefore, after dismantling and leveling the edges of the material remaining on the roof, the replacement is carefully fed up and laid. The difficulty lies in the fact that such strips have the full length of the slope, and they must be fed so that they do not bend.
The lock is rolled up with a roofing frame, although there is also an automatic and semi-automatic folding tool for this. And it is best to use a universal frame to close the fold.
VIDEO Of course, if the roof was repaired with metal roofing materials that do not have a galvanized or alumino-galvanized coating, then painting work will be required to protect the coating from corrosion. All repair work, as a rule, is carried out with the same materials that are used in this case.
