The operation of a metal roof, despite its durability, cannot be done without routine maintenance, which consists of replacing it in areas whose area is no more than 10% of the entire roof. Routine metal roof repairs include installing patches, repairing cracks, painting the roof, and replacing damaged areas.
- galvanized iron;
- titanium-zinc;
- aluminum;
- copper
Protection against corrosion and rust of metal sheets is carried out by covering them with paint, oxides of the metals themselves or special polymer compounds.
Metal roofs are durable, but they also require periodic repairs.
Preparing a metal surface for repair work
Before repairs, the roof must be prepared. First you need to clean it from dust, rust and other dirt, using first a hard, then a soft broom and brush. To clean rusty areas, you will need metal brushes. After eliminating the rust, the dust from it is immediately swept away and the area is painted. Then a visual inspection of the roof is done to identify cracks and holes formed when clearing snow and ice with shovels.
At least two people must participate in the inspection. One conducts it in the attic, armed with a long stick, the other on the roof, taking with him a piece of chalk. When a hole is discovered from the attic, a person knocks on the roof with a stick, and his partner from above marks this place with chalk. After identifying all defects, you can begin to eliminate them immediately.
This is important! It is advisable to inspect the roof on a clear sunny day with good visibility, in which case even the smallest crack or hole will not be hidden from your gaze.
Inspection of seam roof damage
Partial repair or complete replacement of roofing materials
To repair a metal roof, patches are used, which come in two types: along the width of the picture for defects on the plane of the sheet, and intermediate ones, which are used to repair damage in or near the ridges. To patch, take a sheet with the necessary allowances for the amount of worn areas. Allowances are required for connections. The area with the defect is uncovered and a patch is placed on it, connecting it to the old coating. On gentle slopes, soldering of seams is used to connect patches to sheets.
Before installing the patch, drying oil is applied, and after the connection, weather-resistant painting compounds are applied, simultaneously painting the joints to avoid corrosion. Patches for small holes ranging in size from 30 to 200 mm are made from tarpaulin, burlap or thick fabric. Small holes up to 30 mm are not patched; they are covered with hot bitumen, red lead putty or special mastic. The roofing sheet around the 30-40 mm hole is cleaned and coated on both sides - from the attic and from the roof.
Fabric and burlap patches require impregnation with liquid oil paint on natural drying oil from grated lead or iron lead. The patches are dipped into the paint completely dry and left for 10–15 minutes. Then they are wrung out and placed on the hole, carefully smoothing and pressing with your hand or a hard brush. The edges must be smoothed especially carefully. After 5–7 days, when the patches are completely dry, you can begin painting. This is done in dry weather. Before painting, the dust collected during this time must be removed with a brush.
Patches made of fabric and burlap are impregnated with liquid oil paint
Gutters, gutters, downpipes, and eaves overhangs are repaired more often, since these are the roofing elements that are most vulnerable when clearing snow and ice.
If the defects make up 50% of the area, then the metal sheets are replaced over the entire surface. A complete metal roof replacement is done in the same way as installing a new one. The removed sheets can be reused on the southern slope. They are cleaned, trimmed, coated with drying oil and paint. They are not suitable for the most critical places. For valleys, eaves overhangs and other vulnerable elements, only new steel sheets are used. Before crimping, all folds are covered with red lead putty.
Repair of metal roofing with rolled materials
To reduce the cost of repairing a metal roof with a lot of wear and tear, you can use rolled materials. Repair work is carried out in the following sequence:
- defects in the sheathing are eliminated;
- drainage devices, gutters and slopes are repaired;
- swollen and torn areas are secured with nails;
- by using metal brushes the surface is cleaned;
- then the rolled materials are laid along and across the standing seams;
- slats are nailed on both sides, having a triangular cross-section and the same height as the rebate;
- The surface is covered with hot bitumen, and roofing felt is glued onto it.
The work is carried out from the eaves to the ridge with an overlap of each subsequent row of 8 cm. When laying transverse strips, the standing seams can be bent towards the plane of the roof.
As soon as a defect is discovered during inspection steel roofing, you need to start eliminating it immediately
Repair using “Polykrov” – a polymer roll-on-self-fill composition
During major roof repairs, a polymer composition is also used without removing the outdated coating. “Polykrov” is a combination of polymer and bulk materials in one composition. Consists of:
- reinforced fiberglass, rolled base "Polikrov-AR";
- “Polikrova-M” mastic, which glues the material to the base;
- self-leveling coating“Polikrova-L”, which is applied in several layers.
The roll base is easy to lay and quickly glued, and the self-leveling layers form a seamless film. Polykrov polymer composition is available in a wide range color scheme. Silver color, according to many, is the best, since its reflective ability creates a feeling of cleanliness and newness of the roof for a long time after repair.
Important to know! When using a building with such a coating negative impact Only the top layer lends itself, the rolled base does not age, so during subsequent repairs only the self-leveling layer is renewed.
The silver color of the roof, due to its reflective properties, creates a feeling of cleanliness of the roof for a long period
Advantages of using "Polykrov":
- no need to remove old coating;
- the parameters of a roof made of a polymer composition are superior to those of the old metal one;
- slight increase in roof weight;
- there is no waste left, since the trimmings are used to insulate abutments and joints.
Technology of application of the polymer roll composition “Polykrov”:
- the folds of the old metal covering are tightly bent to the slope;
- all debris is removed from the surface;
- mastic is applied to glue strips of fiberglass or burlap 15–20 cm wide;
- the insulating coating and “Polykrov” are being laid;
- the strip “Polikrov-AR-130” or “Polikrov-AR-150” is glued to the roof ridge;
- The roof surface is coated with “Polikrov-L-1” varnish.
When using “Polykrov” there is no need to remove the old coating
When the length of the slope does not exceed the length of the roll, which is 20–22 m, the covering is made with a continuous sheet from the ridge to the eaves overhang. On large areas, roll material must be glued from bottom to top.
Features of "Polykrov":
- withstands temperatures from -60 to +140 °C;
- Available in rolls of 20 m2, width 90 cm, material thickness 2 mm;
- mastic is sold in barrels or cans of 200 and 20 liters, respectively;
- service life up to 25 years.
This is important to know! The most vulnerable places in a metal-coated roof are at the joints, as well as between the sheathing bars on the attic side when the temperature and humidity conditions are violated. Since nails, wire, bolts and other fasteners are made of non-galvanized steel, when connected to galvanized steel, electrical steam is generated that destroys the galvanized steel. In this case, a one- or two-layer roofing material will help.
Repair of an old metal roof using the Polykrov polymer composition
Painting a metal roof: technological requirements
The paint film is destroyed by exposure to water, hydrogen sulfide, air, carbon dioxide, sand, dust and smoke. In order for their impact to be minimal, when dyeing it is necessary to comply with the technological requirements for dyeing. The painting should be even and smooth so that dust and sand do not linger on it. An uneven thickness of paint layer promotes the formation of cracks in which water will accumulate and destroy the roof. Durable coloring is achieved by applying 2-3 layers to a previously prepared base.
Painting of the repaired roof is carried out on a clean and dry base using brushes.
Metal roof itself is reliable and durable. Its functionality and service life depend on how high-quality and technologically the repair is performed. Therefore, it is very important to have metal roof repair work done by professionals.
The roof is one of essential elements in the design of the entire building. Therefore, it is necessary that it be reliable and well protected from negative weather influences.
Proper design of this structural element will reliably protect the house from precipitation and adverse weather conditions. But still, under the influence of time, many materials become unusable, and in order for the roof to continue to serve properly, sometimes significant repairs or replacement of roofing materials are required on your own or with the help of friends.
Before you begin roof repairs, you need to assess its condition. First, it is recommended to inspect the inside, check the condition of the rafters and the strength of the flooring in the attic. Only after this can you begin to inspect the outer surface of the roof.
Pay attention not only to the condition of the material with which the roof is covered, but also to the joints of the covering elements, and whether they are tightly adjacent to the pipe, ridge or ventilation system. After the inspection, you need to make a decision on the scope of repairs and upcoming costs.
If you only have to emergency repair roofs of a house to restore local damaged areas, then such roof repairs can be done by a non-roofing specialist. Current repairs involve replacing from 10 to 40% of the entire roofing area and sometimes require the intervention of specialists. In the case of major repairs (more than 40% of the roof), large sections may need to be dismantled, and it may even be necessary to replace the entire covering and other roof elements.
Basic safety rules
When carrying out work on the roof itself, you need to be extremely careful. If you experience dizziness at heights, or are afraid of heights, then better repair roofing should be done by an experienced professional.
If you still decide to update or repair the roof yourself, then you should adhere to the following tips.
- Under no circumstances should you start work in bad weather, be it rain or wind. Carrying out work on the roof in this case becomes quite dangerous, since roofing material it becomes wet and you can simply fall and slip.
- When carrying out work, clothing should be loose enough, not restrict movement, and shoes should not slip.
- It is best to have a ladder that has extra length. It should be well fixed and very stable.
- You need to move exclusively along the middle part of the stairs, trying not to cling to its sides.
- Taking a partner with you on your team is the best decision. If something happens, he will always be able to insure you, provide necessary tool, and also be useful in cases where it is difficult to carry out work alone.
- When repairing a roof that has a very large slope, it is necessary that the ladder have special brackets that will be quite convenient to secure it to the roof ridge. This is necessary so that during work the load is distributed evenly.
If suddenly a situation arises where it is very difficult to get to the damaged area of the roof or it is practically inaccessible, for example, if it is necessary to repair the roof on the balcony apartment building, then it’s better not to risk it and leave this idea.
Repairing the roof of a house is not a case when you should risk your life and climb anywhere yourself. It is better to seek help from professionals who work at heights, for example, industrial climbers.
How to repair a roof made of natural (ceramic) tiles?
The reasons why there may be a need to change the tile cover vary. But the most common is that cracks form on the surface of this material, through which water penetrates into the premises. Such cracks can appear when there is a sharp change in temperature, when the coating sharply contracts or expands. Another reason may be that the mortars used to fasten the tiles may crumble over time.
As for the first case, the structure of the entire roof needs to be properly strengthened. To do this, you can strengthen the rafters using wooden blocks. In this case, the cracks can be covered up cement mortar.
In case number two, you need to replace the old crumbled solution with a newer one. The composition of the new solution can be as follows: one part of lime is added to two parts of sand. For a better binding effect, tow fibers can be added to the mixture.
But the most important cause of roof leaks are places where the waterproofing layer breaks, which during installation is placed between the rafters and the laid sheathing. Tiles are attached to them on top. Such defects can be eliminated in simple sequential steps:
Using a tool such as a trowel, in the place where it is planned to carry out repair work, it is necessary to remove to the side those pieces of roofing that need to be replaced. And then hammer small wooden wedges under the tiles that are on top.
Then you need to remove all the fasteners from the slats throughout the entire rafter structure.
After the completed manipulations, you need to use construction knife cut off the part of the waterproofing that is damaged, and then apply a patch, preferably a larger one, and glue its edges special glue polymer-based;
Then you need to measure the gaps between those ends of the beam that were cut, and then cut those parts that will be missing. Be sure to remember to soak these sections with an antiseptic. And of course, after processing, you need to nail in new fragments using anti-corrosion nails.
The last stage there will be a return to their place, but only new, shards of roofing tile material.
After all the work carried out, it is necessary to protect the entire structure as thoroughly as possible from mold, as well as from possible moisture ingress. To do this, you need to treat the entire surface with a composition that consists of a mixture of synthetic resins and primer. This composition can perfectly protect the roofing surface, as it creates an excellent screen during interaction with water, which will reliable protection from the water! Special roof paint can also provide additional protection against precipitation.
Basic methods of repairing sheet metal roofing
The reasons that can damage metal roofing materials are very different. This could also be metal corrosion or poor sealing during previous work on processing seams on a bonded coating. Be that as it may, if signs of damage are identified, it is necessary to take measures to eliminate them, that is, begin repairing the roof of the house. Since if this is not done, then in the future this may turn out to be additional problems.
How to repair a seam roof?
If it so happens that any defects were discovered in the sheet roofing, then you need to begin eliminating them as soon as possible. Since, if this is damage from metal corrosion, then it is necessary to exclude the moment of its spread to all other areas of the roof.
In case of minor problems, the roof can be repaired as follows:
- thoroughly clean the area to be repaired from all surface damage using a steel brush;
- need to cut the patch out metal sheet, but with a margin so that it is larger size than the area of the defect (at least 5 centimeters);
- then, where the damage occurred, it is necessary to carefully cover the edge of the patch and the edges of the damage with a special flux, which contains lead and zinc, and then solder them reliably with a soldering iron;
- after the applied patch has cooled, the excess solder should be cut off either with sandpaper or a file;
- so that the repaired area does not stand out, you can apply a layer of façade paint to it to match the color of the entire roof.
If the damage is too large, then it is best to completely replace all sheets of corrugated sheets in those places where they are damaged.
Effective repair of metal roofing
Typically, the appearance of a leaking metal roof is due to an abundance of errors in its installation, corrosion, and there are also frequent cases when the fasteners are not firmly secured and become significantly loose. Damage as a result of cleaning the coating is also possible.
If scratches are found on the metal tiles, they must be immediately removed using special paint.
And if you find gaps in the spaces between metal part structures and valley elements, and in some cases under the ridge, they must be filled with silicone sealant.
An obviously through hole in the roofing can be easily repaired with a soldering iron and a patch. If there are a lot of holes, you need to replace all damaged sheets.
In most cases, fasteners become loose because they may be poor quality. Therefore, you need to select only high-quality fasteners. Then it can become loose, since washers, which are made, for example, from rubber, do not last very long and can still undergo the process of becoming loose. In this case, it is better not to try to fix already broken washers, but to replace them with new fasteners.
A much larger amount of work is required if the roofing “pie” itself is made incorrectly. As a rule, pitched roofs that are specially insulated leak quite often as a result of the use of cheap vapor barrier materials. Materials such as, for example, perforated film, although inexpensive, can very poorly remove moisture that can accumulate in it.
The solution to this problem may be to replace the worn-out film with a more durable one. modern material, for example, a diffusion membrane. It will perfectly protect the insulation from moisture penetration. But it is worth recognizing that this method is not cheap, because in this case, you will have to completely change the entire coating, and this can lead to significant financial costs.
Bituminous shingle roof repair
This type The good thing about this material is that bitumen is a very versatile material, which means you can easily replace all sheets and tiles. Is it true, weather conditions for repairs must fully comply with the work being performed. Recommended temperature at which to carry out construction work, must be at least +5 degrees.
This limitation is introduced due to the physical properties of bitumen. On severe frost this material becomes very brittle and can simply crack. If cracks appear on the tile, then you need to lift it and cover it on the inside with a layer of special roofing adhesive, or, alternatively, use mastic. After this, the tile must be pressed tightly and the outer part treated with the same composition.
- Defects of a more serious nature can be completely eliminated by replacing the entire roofing covering.
- Using a small crowbar, you must very carefully lift all the tiles that are located above, and then you can remove the one on which damage is found.
- The nails that secured the damaged shard must be removed using a nail puller.
- You need to apply glue along the inner edge of the top edge.
- Then you need to insert it under the tile that is located a little higher in the top row. It should be fixed with small nails, which are intended for roofing.
- The edges that are located above and below the one that has already been laid must also be lubricated with glue, and then pressed tightly.
Slate roof repair
When planning to repair a roof with slate covering, you need to move on this material with the utmost caution, because slate sheets are very fragile, and if they break, you can simply lose your balance and fall.
When repairing a slate roof, it is best to use the so-called staircase. Since it can contribute to the optimal distribution of the entire body weight over the entire surface of the roof being repaired.
Do-it-yourself roof repair is not difficult. If damage is detected, then you only need to close it with a cement mortar, the proportions of which are as follows: add two shares of quartz sand to one share of cement.
Sometimes a method is used to restore the tightness of a slate covering using adhesive tape, which has a butyl rubber base. To do this, clean the damaged area with a clean cloth, first moistening it with gasoline or white alcohol (white spirit).
First you need to cut required size piece of tape, then remove the backing paper from it and stick it over the crack. The crack follows
overlap by about 4 or 5 centimeters. This repair tape is usually covered on the front side with a durable non-woven material that can be painted in desired color so that the repaired areas are not noticeable. There is also a special roof paint for these purposes.
If you notice that your slate roof has started to “knock”, check to see if the slate nails are loose. You need to replace them with new ones or secure them with self-tapping screws with sufficient wide hat. Due to the fragility of slate sheets, when removing old nails, care must be taken to distribute the load on several adjacent waves using a wooden strip.
You should clean the slate roof from accumulated debris or snow with a soft brush or broom. Even careful cleaning with a wooden, or even more so, an iron shovel can significantly damage a slate roof.
Completion of repair work
After all repair work is completed, begin removing debris and other waste from the roof and around the house. It would be advisable to prevent waterproofing with a special roofing adhesive or resin, i.e. treat areas around pipes, hatches, antennas. To update the color of some roof elements, different roof paints are available for sale.
The best time to execute repair work Is it spring or autumn, the street is dry, warm, but not hot. This is the most convenient time for inspection and preventive maintenance on the roof of a house.
Be brave, and then the roof of your home that you have repaired will not only protect your family from bad weather, but will also allow you to be proud of your contribution to this necessary cause!
When a roof covered with soft roofing materials begins to leak, there is an urgent need for rehabilitation. Sometimes you can get by with patch restoration, which boils down to gluing joints or patching up cracks. And sometimes only labor-intensive and thorough will help.
Signs of defects in soft roofing coverings
Before repairs, it is necessary to carefully examine the roof and determine in which places repairs need to be made. Special attention It is necessary to pay attention to the following defects:
- small cracks, delamination in places where panels are glued;
- depressions and pits in which moisture accumulates;
- dampness, rotting of the coating, growth of the roof with fungus or moss;
- swelling of the coating occurs after moisture penetrates inside;
- large abrasions and tears from mechanical impact.
After a thorough inspection of the roof, you can determine whether major or minor repairs need to be carried out.
What materials should I use?
The modern market offers a huge range of roofing roll materials. The most common:
- weldable glass elastomer;
- bikrost;
- membranes;
- bitumen;
- roofing felt
Methods for minor repairs to soft roofs
Current repairs are carried out when there are small cracks, loose joints, abrasions and tears on the roof. Usually a patch method is used to repair the coating. Cracks, abrasions and tears are removed as follows:
- the damaged area is filled with bitumen;
- roofing felt or other material, pre-cut to the size of the damaged coating, is glued on top of the mastic;
- the patch is secured with a layer bitumen mastic, evenly distributed with a roller over the roof surface.
Broken joints are eliminated in the following sequence:
- lift and dry the peelable surface of the material using a gas burner;
- apply bitumen mastic with a roller;
- lower the dried material;
- re-treat the joint with bitumen.
Major renovation
Repairs to sheet roofing should be carried out after a thorough inspection. If there are multiple areas on the roof where water collects, there are deep scratches and chips in the rolled covering. Tools you may need when fixing your roof:
- gas burner for heating panels;
- sheets of roofing felt material;
- knife for removing defective areas;
- sealant and waterproofing bitumen mastic;
- broom for cleaning;
- insulation if necessary;
- reinforcing mesh and cement for screed.
Advice! It is recommended to use a gas burner as heating equipment, as it will allow the soft bitumen sheet to heat up faster. This greatly simplifies the installation of the coating.

Due to their specific nature, soft roofs require regular maintenance and care. It is “softness” that is the main disadvantage - this type of roof is poorly protected from mechanical damage. The destruction of the waterproofing layer even in two or three places leads to the fact that after some time most of the roofing carpet becomes unusable. But such roofs are usually characterized by good repairability and restoring the roof is not too difficult.
If no more than 40% of the roof is damaged, you can get by with routine repairs (restoration of damaged areas). If more, a major overhaul is required, which involves removing the old coating and laying a new one.
Defects in soft roofing
To identify damage to a soft roof, you do not need to do complex examinations; a careful examination of the surface is sufficient. Possible damage to the roof covering:
- Clear peeling at the joints.
- The presence of holes and depressions in which water can accumulate. In these places, corrosion processes and the appearance of fungus or mold are possible.
- Cracks, serious abrasions, tears, mechanical damage.
- Bloating. Usually this is evidence that moisture is accumulating under the coating in this place, therefore there are violations of the integrity of the waterproofing layer.
Construction materials and equipment for repair work
Before starting repairs, you need to carefully calculate the amount of roofing material needed and draw up detailed plan works This will significantly reduce repair time. To restore the roof you will need:
- Gas cylinder, reducer and burner.
- Vacuum cleaner (industrial), sweepers.
- Assembly cutter.
- Spool (pipe).
- Spatula.
- Construction tape.
- Axe.
- Rolling stick.
- Bitumen mastic.
If a major repair of a flat roof is necessary, you may have to do a cement-sand screed in places or completely. You will need soil, sand, cement and water.
The modern roofing materials market offers simply a huge selection of rolled roofing materials. Some of them:
- For the top layer - Isoelast, Linocrom, Uniflex, Isoplast.
- For the installation of the bottom layer - Technoelast, Bireplast, Isoplast, Uniflex.
The outer layer materials are coated with mineral particles that protect against sun rays. The thickness of the outer layer roll materials is 4.5-5 mm. The thickness of similar materials of the inner layer is 3.5 mm.
SNiP
When carrying out restoration work on soft roofs, you must be guided by the following documents:
- SNiPII-26-76
- SNiP 3.04.01-87
- SNiP 3.04.01-87
- SNiP Roof Soft 12-03-2001
All documents regulating roofing work should be carefully studied. However, we must remember that these regulations were adopted a long time ago and some points are hopelessly outdated.
Technology and sequence of do-it-yourself repair work
The sequence of work for repairing a soft roof roof depends on the roofing material you use. These can be either rolled fused materials or flexible tiles. Technologically, their installation depends on (flat and pitched).
Flat roofs
Any repair of any surface begins with preparing the base. It is very important to always follow this point, otherwise even the most advanced roofing materials will not last half the time they should last.
Current repairs can be performed in two ways:
- partial replacement of the old roofing carpet;
- laying new layers of roofing over the entire area over the old covering.
If you are just going to patch the roof, you need to cut out all the damaged areas. Thoroughly clean the surface for the patches, remove dust and prime them. Fill with hot mastic and glue the new one onto it. roll covering. The area of the patch must be at least one third larger than the surface to be restored. The edges are carefully sealed.
Such repairs are justified if there is a very small amount of damage to the roofing. At best, your patch will last 3-4 years.
On small roofs it is quite possible to do this without removing the old one. If such repairs have already been carried out, you need to take into account that each layer of roofing increases the load (approximately 1.5-2 kg per sq. m).
Once you are sure that your roof can support it and that the old roofing carpet is not in poor condition, you can begin preparing the foundation. Having eliminated the defects and cleaned it, lay a new soft roof in two layers in the usual way, depending on the material.
Major repairs usually include not only the dismantling of the old roofing, but also the repair of all roof elements - fences, parapets, gutters and water inlets. If necessary, a partial screed or screed of the entire roof area is done.
You can remove the old coating using a special machine, or you can do it the old fashioned way - using an ax and a metal spatula or scraper. The base, regardless of what you are going to do next, must be cleaned of dust, dirt and degreased. If there are no serious defects on it - holes, holes, large potholes, you can do without a screed. But it is still necessary to partially restore the base - it is desirable that the surface is smooth, dry and clean.
Roll fused roofing materials today are made from durable materials(polyester, fiberglass) with the addition of modifiers. Both sides are coated with a polymer-bitumen composition. The top layer is protected with mineral coatings, and the bottom layer is covered with a special film.
The service life, depending on the modifier, ranges from 10 to 30 years. A well-executed repair will enable your roof to protect your home from precipitation for several decades. Roof covering on flat roofs done in several layers.
Installation of roll materials quite simple - gas burner the bottom bitumen layer is heated, glued to the base and rolled. The rolls are rolled out with an overlap of 15 cm, the joints are carefully taped. The second layer is mounted across the first. As a result, you get an almost seamless coating. When installing the roof, special attention should be paid to sealing the junctions with the vertical roof elements.
For more information about the technology of carrying out repair work using weld-on materials, see the video.
Pitched roof
Soft roofs (flexible tiles) on pitched roofs are coming into fashion. This type of roofing has a number of undeniable advantages:
- Long service life (up to 50 years).
- Low windage, such a roofing covering will not be torn off even by a hurricane.
- High noise insulation.
- Zero waste. No more than 5% of flexible roofing ends up in waste, even on roofs of complex configurations.
In addition, roofs covered with flexible tiles look original and impressive. The basis of this coating is high-strength fiberglass. Flexible tiles surprisingly easy to use and .
Despite its excellent performance, such a roof may also need repairs. To replace a significant section of the roofing carpet, you will have to re-lay the entire slope. But this happens extremely rarely (for example, in the case of a tree falling on the roof).
Small cracks or blisters can be easily repaired with roofing adhesive. To replace a fragment of the coating, you need:
- Lift the tile above and remove the damaged one.
- Pull out fastening nails nail puller
- Apply roofing adhesive in an even layer to the new tiles.
- Place it in place and secure it with additional roofing nails.
- Apply roofing adhesive to the top piece where there is an overlap.
- Press the repaired section of the roof for a while.
Repair cost
If you are doing the repairs yourself, it is worth making a preliminary estimate before starting work. Knowing what roofing material will be used for repairs and its price, you can determine the cost of repairs with great accuracy.
Unless you're a professional builder, you're unlikely to be able to factor in shipping costs and costs consumables, but this slightly increases the cost of repairs. On average current repairs will cost you from 60-80 rubles per square meter, a capital one will cost more than 200 rubles. Builder services will increase costs by 2-2.5 times.
Repair of small areas soft roofs can be done without hiring professional roofers. Installation of such coverings is quite simple, but you will need to be careful and careful when carrying out the work - the roof does not tolerate carelessness. Another prerequisite is reliable insurance. Don't forget that any roofing work- this is work at heights.
