Roof screed repair technology. Soft roof repair: technology, estimate and SNiP rules

The roof is one of the most important 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 their own or with the help of friends.

Before you start repairing the roof, you need to assess its condition. First, it is recommended to inspect from the inside, check the condition of the rafters and the strength of the flooring in the attic. Only then 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 coating elements, as well as whether they are tightly adjacent to the pipe, ridge or ventilation system. After the inspection, you need to decide on the amount of repairs and upcoming costs.

If you only have an emergency repair of the roof of the house to restore local damaged areas, then such a roof repair with your own hands can be performed even by a non-roofing specialist. The current repair involves the replacement of 10 to 40% of the entire roofing area and sometimes requires the intervention of specialists. In the case of major repairs (more than 40% of the roof), it may be necessary to dismantle large areas, and maybe even replace the entire coating and other roof elements.

Basic safety rules

Carrying out work on the roof itself, you need to be extremely careful. If you experience dizziness at height, or you are afraid of heights, then it is better to leave the roof repair to an experienced professional.

If, nevertheless, a decision is made to update or repair the roof on your own, then you should adhere to the following tips.

Never start work in bad weather, be it rain or wind. In this case, it becomes quite dangerous to carry out work on the roof, since the roofing material becomes wet and you can simply fall by slipping.
Clothing during work should be loose enough, not hinder movement, and shoes should not slip.
It is best to have a ladder that has an extra length margin. It should be well fixed and be very stable.
You need to move exclusively along the middle part of the stairs, trying not to cling to its sides.
Taking a teammate with you is the best decision. He, in which case, will always be able to insure you, provide the necessary tools, 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 stairs have special brackets that will be convenient enough to fix it to the roof ridge. This is necessary so that during the work the load is evenly distributed.

If suddenly a situation has arisen that it is very difficult to get to the damaged section of the roof or it is practically inaccessible, for example, if necessary, repair the roof on the balcony of an apartment building, then it is better not to take risks and leave this idea.

Repairing the roof of a house is not the case when it is worth risking your life and climbing anywhere on your own. 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?

There are various reasons why it may be necessary to change the tiling cover. 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 with a sharp temperature drop, when the coating is sharply compressed or unclenched. 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 must be properly strengthened. To do this, you can use wooden bars to strengthen the rafters. In this case, cracks can be covered with cement mortar.

In case number two, you need to replace the old crumbled solution with a newer one. The composition of the new solution may 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 the places where the waterproofing layer breaks, which, during installation, is placed between the rafters and the laid crate. Tiles are attached to the top. Such defects can be eliminated by 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 the roof that should be replaced. And then hammer small wooden wedges under the tile that is on top.

Then you need to pull out all the fasteners from the rails on the entire truss structure.

After the manipulations have been done, it is necessary to cut off that part of the waterproofing that is damaged with a construction knife, and then apply a patch, preferably a larger one, and glue its edges with special polymer-based glue;

Then it is necessary to measure the gaps between those ends of the timber that were cut off, and then cut those parts that will be missing. Be sure to remember to soak these segments with an antiseptic. And of course, after processing, you need to nail new fragments with anti-corrosion nails.

The last step will be the return to its place, but only new, shards of roofing tile material.

After all the work carried out, it is necessary to protect the entire structure as carefully 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 soil. This composition will perfectly protect the roofing surface, as it creates an excellent screen in the process of interaction with water, which will be a reliable protection against water! Special roof paint can also provide additional rain protection.

The main methods of repairing sheet metal roofing

The reasons that can damage metal roofing materials are very different. This may be metal corrosion or poor sealing during previous seam work on the bonded coating. Be that as it may, when signs of damage are identified, it is necessary to take measures to eliminate them, that is, to begin repairing the roof of the house. Since if this is not done, then in the future it may turn into additional problems.

How to repair a seam roof?

If it so happened that any defects were found in the sheet roofing, then you need to start fixing 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 sections of the roof.

With minor problems, the roof can be repaired as follows:

thoroughly clean the repaired area from all damage on the surface with a steel brush;

you need to cut a patch from a metal sheet, but with a margin so that it is larger than the defect area (at least 5 centimeters);

then, where the damage has occurred, carefully cover the edge of the patch and the edges of the damage with a special flux, which includes lead and zinc, and then solder them in a reliable way with a soldering iron;

after the applied patch has cooled, the excess solder should be cut off either with sandpaper or with a file;

so that the repaired area does not stand out, you can apply a layer of facade paint on it to match the color of the entire roof.

If the damage is too great, then it is best to completely replace all sheets of corrugated board in those places where they are damaged.

Effective metal roof repair

Usually, the appearance of a leaking roof from a metal tile is an abundance of errors during its flooring, corrosion has formed, and there are also cases when the fasteners are not firmly fixed and become loose. Damage due to cleaning of the coating is also quite possible.

If scratches are found on the metal tile, they must be immediately eliminated with a special paint.

And if you find gaps in the gaps between the metal part of the structure and the grooved elements, and in some cases under the ridge, then they must be filled with silicone sealant.

A hole of a clearly through character in the roofing is easily eliminated with a soldering iron and a patch. If there are a lot of holes, you need to change all damaged sheets.

Fasteners loosen in most cases because it may be of inadequate quality. Therefore, you need to select only high-quality fasteners. Then it can become loose, since the washers, which are made of rubber, for example, do not last very long and can still undergo a loosening process. In this case, it is better not to try to fix the washers that have already failed, but to replace them with new fasteners.

Much more work is required if the "pie" of the roof itself is made incorrectly. As a rule, pitched roofs, specially insulated, as a result of the use of cheap vapor barrier materials, leak quite often. Materials such as, for example, perforated film, although they are inexpensive, can very poorly remove moisture that can accumulate in it.

The solution to this problem can be the replacement of the obsolete film with a more 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.

Shingle roof repair

This type of material is good because bitumen is a very versatile material, which means that all sheets and tiles can be easily replaced. True, the weather conditions for the repair must be fully consistent with the work performed. The recommended temperature at which construction work can be carried out should be at least +5 degrees.

This limitation is introduced due to the physical properties of bitumen. In severe frost, this material becomes very brittle and can simply crack. If cracks appear on the tile, then you need to lift it up and cover it with a layer of special roofing glue from the inside, or, alternatively, use mastic. After that, 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.

Using a small crowbar, you must very carefully pry up all the tiles that are located above, and then you can remove the one on which damage is found.

The nails that fixed the damaged shard must be pulled out with a nail puller.

Glue must be applied along the inner edge of the top edge.

Then you need to insert it, under the tile, which is located a little higher in the top row. It should be fixed with small carnations, which are intended for the roof.

The edges that are located above and below the one that has already been laid must also be greased with glue, and then pressed firmly.

Slate roof repair

If you are going to repair a roof with a slate coating, you need to move along this material with the utmost care, because slate sheets are very fragile, and if they break, you can easily lose balance and fall.

In the case of a slate roof repair, it is best to use the so-called ladder-ladder. 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 found, then it is only necessary 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 coating using adhesive tape, which has a butyl rubber base. To do this, clean the damaged area with a clean cloth, moistened with gasoline or White spirit (white spirit).

First you need to cut off a piece of tape of the required size, then remove the protective paper from it and stick it on the crack. Crack follows

overlap by about 4 or 5 centimeters. This repair tape is usually covered on the front side with a non-woven, durable fabric that can be dyed to your desired color so that repaired areas are not visible. For these purposes, there is also a special paint for roofs.

If you notice that the slate roof has begun to “knock”, check to see if the nailing of the slate has loosened. You need to change them for new ones or fix them with self-tapping screws with a fairly wide hat. Due to the fragility of slate sheets, when removing old nails, care must be taken to ensure that the load on several adjacent waves is distributed using a wooden plank.

Clean the slate roof from debris or snow with a soft brush or broom. Even careful cleaning with a wooden, and even more so, with an iron shovel, can significantly damage a slate roof.

Completion of repair work

After all repairs are completed, take care of removing debris and other debris from the roof and around the house. It would be desirable to prevent waterproofing with a special roofing adhesive or resin, i.e. process areas around pipes, hatches, antennas. To update the color of some roof elements, different roof paints are commercially available.

The best time to carry out repairs is spring or autumn, the street is dry, warm, but not hot. This is the most convenient time for inspection and maintenance work on the roof of the house.

Go ahead and then the roof of your home repaired by you will not only protect your family from bad weather, but will also allow you to be proud of your contribution to this necessary cause!

Our article describes soft roof repair technology + video. We touched on the most frequently asked questions on this topic. Describe the types of repairs and how they are carried out.

There are several answers to the question of how to repair a soft roof. Everything will depend on the amount of damage and their complexity.

Typically, repairs are divided into two types:

Current - damage to the roof cover is less than 40% of the total roof area.
Capital - damage is more than 40% of the roof area.

No matter how strange it may sound, but the main reason for the leakage of roofs made of soft rolled materials is the destruction of the bituminous layer, which provides the waterproofing properties of this material.

It is not difficult to repair the soft roof of the garage with your own hands, since this building is small in size. But on other buildings, these works will not take much time and effort, especially when it comes to current repairs.

In fact, rolled roof coverings are considered the easiest to install. They do not require any special equipment or skill to install.

As mentioned above, before starting work, it is necessary to determine the amount of damage. How it's done? We need to climb to the roof and examine the coating. What to search?

In places of overlap and connection of the panels, there may be visible delaminations;
There may be visible depressions and pits on the roof surface that can hold water;
In places where water stagnates, it should be examined for decay of the material, the appearance of moss or fungus;
Blisters on the surface of the roofing cover indicate that moisture has penetrated inside in this place;
The presence of visible mechanical damage, abrasions, cracks, breaks.

After inspecting the roof, it can be concluded what type of repair will be needed. Based on this, an estimate is made for a soft roof. What does it include?

Advice! To draw up an estimate, it is not necessary to call a specialist, you can do it yourself. But if you are not confident in your abilities, then of course you should contact the appropriate firms.

estimate

If the repair work will be carried out by a team of specialists, then first of all they will indicate the list of works, namely:

Full or partial removal of the old roof.
Preparation of the surface for the subsequent installation of the roofing.
Installation of the top layer of the roof and coating of seams.
Waterproof top layer.
Combustible materials for the burner.
Consumables and their delivery.

If it is decided to carry out repairs independently, then the estimate will include only the cost of the material used and its delivery.

Those who have not yet decided whether they will do it themselves or hire workers can contact a roof repair company. By providing them with the following information, you can find out approximately how much the repair will cost.

Roof plan with all dimensions, to calculate the amount of material.
Lengths of cornice overhangs, junctions with walls and parapets, thickness and height of the latter.
The presence of shafts on the roof, their number and size.
The presence of pipes and other elements on the roof, their sizes and quantities.
The condition of the roof, it is desirable to take photos.
Approximate list of repair works.
What roofing material will be used.

SNiP rules

Work should be carried out in accordance with:

SNiP soft roof 12-03-2001.
SNiP 12-01-2004 "Organization of construction";
SNiP 3.03.01-87 "Bearing and enclosing structures";
SNiP 3.04.01-87 "Insulating and finishing coatings";
SNiP 12-03-2001 "Labor safety in construction" part 1. General requirements;
SNiP 12-04-2002 "Labor safety in construction" part 2. Construction production;
POT R M-012-2000 "Intersectoral rules for labor protection when working at height";
SNiP soft roof repair 11-26-76 (1979).

Although many of those who perform roofing repairs do not always comply with them. This is due to the fact that most of the above rules were developed back in Soviet times. Much has changed since then, including materials and technology.

For your information: ignorance of these rules does not affect the quality of work. If the workers know their job well, roof repairs will be completed quickly and reliably.

Repair and installation of a soft roof should begin with the preparation of the base on which the material will be laid.

If we talk about the current repair, there are several options. Partial replacement (patches) and repairs can be performed according to the old one (1-2 layers of new material are laid on the old cover).

If patches are placed, all defects are removed in the places where they are laid (cut down or pierced). Then the surface is cleaned of debris and dust, poured with bituminous mastic or sealant.

A piece of roofing material or other rolled material is laid on top. In size, it must exceed the size of the repaired surface.

The edges are carefully smeared with bituminous mastic. But this method usually does not work. Therefore, many use the following method of current repair - “the old way”.

A soft roof for a garage and not only, during current repairs, it can be laid without removing the old cover. With this method, it should be borne in mind that the fusing of two more layers will lead to an increase in the load on the roof.

So it’s worth first finding out how much weight the walls and floor supports can withstand.

For example, the following calculation can be given: on average, modern materials have a mass of 4-5 kg / m 2, if the roof area is 1000 m 2, the load on the roof will increase by another 5 tons. And so, instead of the base, use the old roofing.

It is pre-cleaned of debris and dirt. The installation of a new layer is carried out in the usual way. This method cannot be used if the previous covering is badly damaged, there are already more than 8 layers of old material on the roof.

Usually, in the course of a major overhaul, a complete replacement of the roofing material, partial repair of the base (screed) and parapets, replacement of cornice overhangs, aprons, abutments, fencing, revision and repair of water intakes and gutters are carried out.

But sometimes the roofs are in such disrepair that they have to be not only repaired, but practically built from scratch. Naturally, this affects the cost of work.

Overhaul of soft roofing is carried out in the following order:

Removing the old cover.
Foundation repair.
Laying a waterproofing layer.
Installation of insulation (if necessary).
A screed is being made.
Roofing material is being laid.
A protective layer is laid.

To perform the work, you will need a gas burner, roofing material, a knife for cutting roofing material, sealant or bituminous mastic, a broom for cleaning the surface, cement for screed, insulation, and overalls.

Capital repairs of a soft roof begin with the removal of the old coating.

For this process, such as, you can use special equipment (the machine removes the coating and immediately rolls it into a roll) or an ax (for convenience, the wooden handle is changed to a metal pipe, its length is chosen individually, according to a person’s height).

If there are no large dents and cracks in it, but only minor damage, then the screed can not be poured. Sometimes the screed is preceded by a layer of insulation. It can be foam, a layer of gravel or other heat insulator.

In the first hours after laying the cement layer, the surface is primed with bitumen, which covers the screed with a thin film and prevents the evaporation of moisture from it.

After the cement has hardened, you can start laying the roofing material. The composition of the soft roof is different, but it is better to use materials based on fiberglass.

They have a longer service life and higher technical characteristics, in contrast to cardboard-based coatings.

Laying starts from the bottom edge of the roof, gradually rising up. Each subsequent row is overlapped (from 10 cm). The greater the angle of the roof slope, the greater the amount of overlap.

For roofing felt, glassine and roofing felts, a protective cover made of bituminous is mounted. It is then sprinkled with stone chips and rolled with a roller.

Advice! When using the latest generation materials, the seams between the rows are not smeared and they are already covered with a protective coating on top. Therefore, less material is wasted.

As you can see, the technology for repairing a soft roof is not very complicated. Two people are enough to complete the work. The choice of materials is entirely up to you.

But I would like to remind you, do not forget to audit the roofing at least once every three years. After all, fixing minor flaws is much easier and cheaper than completely covering the roof.

Roof of a residential building

The main cause of damage and deformation of soft roofs is operational wear. In some cases, defects may be caused by installation or maintenance errors. Regardless of the reason that caused the violation of the integrity of the coating, the repair of soft roofing should be done as soon as possible. This will help to avoid the complete dismantling of the old coating and the re-arrangement of the roofing material.

Prevention

In order to delay the need for repairs, preventive measures should be taken to protect the roofing:

During operation, the roof slopes may sag. The reason for this is the excessive load that the soft roof is subjected to. The load may be the result of errors during the installation of the roofing or the result of rotting and deformation of the beams on which the roof rests. The load is caused by natural phenomena. In Moscow and other regions of Central Russia, it is often caused by snow. Therefore, the soft roof should be regularly cleaned of it, as well as dirt and debris.
Roofs should be periodically washed with ordinary clean water supplied under pressure. After washing, the surface is treated with special compounds that protect the outer layer of the roofing cake from moss and mold. It is sufficient to flush once a year.
Additional preventive measures are required in regions with high humidity. Roofs of houses in such areas are additionally protected. For example, a zinc strip can be installed near the ridge.
In winter, in Moscow and Central Russia, it is necessary not only to regularly remove snow and icicles, but also to treat the surface with chemical compounds that prevent the accumulation of snow and the formation of an ice crust.
If trees grow near the house, it is necessary to cut off the branches hanging over the roof. The distance between the nearest tree branches and the roofing should be at least one meter.

These measures help to avoid frequent repairs of soft roofs.

Defects

It is necessary to start repairing a soft roof if at least one coating defect was found during the examination. These include:

Mechanical damage to the roofing pie.
Presence of plants, moss or mold.
Swollen areas.
Flaking of roofing material.
Cracks.
Damage to previous patches.

Any of these defects requires immediate intervention and repair of the soft roof surface. Otherwise, they will cause roof leaks.

Roof installation

Depending on the frequency of occurrence of leakage, there can be different types:

Manifested immediately after precipitation. Most often, leaks of this type are caused by mechanical damage to the roofing pie or natural wear and tear. If a leak appears immediately after installation or repair of the coating, we can say that the work was done in violation of the technology, or poor-quality materials were used.
Appearing some time after the snow melts. Such leaks may indicate that mechanical damage or cracks are present at the joints or in the areas where the roofing pie adjoins the ventilation ducts.
"Flickering" leaks that appear periodically. They are caused by microcracks in the coating. When flickering leaks appear, a major overhaul of a soft roof is most often required.

Even if there are no leaks, the roofing should be inspected regularly. The objectives of such a survey in the spring are:

Detection of blisters, determination of their size and nature.
Assessment of the state of waterproofing roofing.
Determination of the integrity of the aprons and the correctness of their installation.

Preparation for work

During the summer period, the following defects can be detected:

Bubbles in the coating.
Cracking of roofing material of varying degrees.

In the fall, the following are revealed:

Clogs in funnels and drains.
Wet walls.
Stagnation of water.

Repair Technology

Repair of a soft roof can be current or capital. Overhaul requires the complete dismantling of old materials with the arrangement of new hydro-, vapor barrier, screed, etc.

The choice of materials for repair

The construction market in Russia and Moscow presents a variety of materials for the repair of soft roof coverings. The roofing pie is arranged in several layers. Materials must meet a number of requirements:

For the outer layer, you need to choose products with mineral dressing and a thickness of 4.5–5 mm.
For the lower layers, materials with a thickness of 3–3.5 mm are suitable.
All textures used must be compatible with each other.

Installation by non-professionals

In Moscow and Central Russia, bituminous roll materials have gained the greatest popularity. They are easy to install, especially on flat roofs, and can be used for roofs of residential and industrial buildings. In terms of coating reliability, bitumen-based roll materials are superior to most other methods of arranging a roofing pie. Such materials are well suited not only for Moscow with its relatively stable climate, but also for areas where there are sharp temperature changes.

Maintenance

Current repairs are carried out with minor damage, cracks or open joints. Cracks and mechanical damage can be eliminated by filling them with bituminous mastic, on top of which a patch is glued. Roll roofing materials are selected for it. On top of it, it is desirable to pour another layer of bitumen.

Opened joints are also treated with bitumen. Before pouring the mastic, you need to thoroughly dry the lower layers of the roofing cake with a gas burner. After drying, bitumen is poured on which the old material is laid, and another layer of mastic is performed.

Overhaul

Work completed

Roof repair is a complex task, the implementation of which is best entrusted to specialists. Moreover, in Moscow and other large cities it is quite easy to find a specialized company providing such services.

Repair is carried out in several stages:

Dismantling of the old roofing pie.
Implementation of a cement screed roof.
Arrangement of steam and waterproofing layers.
Laying of rolled roofing materials.

Violation of any of the stages of the technological process will lead to the fact that the soft roof will be quickly damaged, and all problems associated with leaks will return, requiring a new repair.

You need to start repair work with surface preparation. The roof must be cleared of debris, and the old roofing completely dismantled. The base of the roof must be level. Next, the operability of the ventilation and drainage systems is checked.

On flat roofs, it is necessary to perform a cement screed, which ensures the evenness of the surface. For additional protection, the base is primed with a bituminous primer or mastic. First, the composition is applied completely to the entire base, including parapets, junctions and podiums. In this case, the surface must be thoroughly impregnated with a primer. After the material has dried, the next layers can be laid.

Mounting process

The vapor barrier is mounted on a cement screed, and then a layer of insulation is laid. To protect the resulting cake, reinforcement with a road mesh is used. Vapor and thermal insulation materials are selected depending on the roof structure.

Materials are laid in different ways depending on the angle of the roof slope. On roofs with a slope angle of less than 15º, the materials must be installed perpendicular to the direction of water movement when it flows into the drainage system. At an angle of more than 15º, laying is carried out from top to bottom in the direction of water movement. After laying the roofing material, all joints, elements of the parapet, gutters, etc. are sealed.

Repair work in winter

Roof repairs in Moscow and Central Russia during the winter period are impossible. In fact, all work in the event of leaks comes down to patching the damaged area. The area to be treated is dried with a gas burner, after which a patch of the required size is welded onto the surface. With the onset of the warm period of the year, the roof is carefully examined, and current or major repairs are carried out, which depends on the degree of damage to the coating.

Conclusion

Repair of a soft roof is required when the slightest defects in the coating appear. Despite the relative ease of laying rolled bituminous weld materials, the work must be carried out by specialists. One single violation of the technological process, which may seem insignificant to a non-professional, can lead to rapid wear of the new coating, and in the worst case, reduce the result of the work to zero.

When a roof covered with soft roofing materials begins to leak, there is an urgent need for sanitation. Sometimes you can get by with a patch repair, which comes down to gluing joints or patching up cracks. And sometimes only laborious and thorough will help.

Signs of defects in soft roofing

Before repair, it is necessary to carefully examine the roof and determine in which places it is necessary to repair. Particular attention should be paid to such defects:

small cracks, delamination at the places of gluing panels;
depressions and pits in which moisture accumulates;
dampness, rotting of the coating, fouling of the roof with fungus or moss;
swelling of the coating occurs after penetration of moisture;
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 to use?

The modern market offers a huge range of roofing roll materials. The most common:

welded fiberglass;
bicrost;
membranes;
bitumen;
ruberoid.

Methods for minor repairs of a soft roof

Current repairs are carried out when the roof has small cracks, open joints, scuffs and tears. The patch method of repairing the coating is usually used. Cracks, abrasions and breaks are removed as follows:

the place of damage is filled with bitumen;
ruberoid or other material is glued on top of the mastic, pre-cut to the size of the damaged coating;
the patch is fixed with a layer of bituminous mastic, evenly distributed by a roller over the roof surface.

The divergent joints are eliminated in the following sequence:

lift and dry the peeled surface of the material with a gas burner;
apply bituminous mastic with a roller;
lower the dried material;
re-treat the joint with bitumen.

Overhaul

Repair of a roof from cloths should be made after careful survey. If there are multiple areas on the roof in which water collects, there are deep scratches, chips of the roll coating. Tools that may be needed when repairing the roof:

gas burner for heating panels;
sheets of roofing material;
knife for removing defective areas;
sealant and waterproofing bituminous mastic;
broom for cleaning;
heater 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 cover.

Due to the practicality and ease of installation, renovation, soft roofing is a popular type of coating. Resistance to aggressive influences completes the list of advantages, and a short service life is a minus, which is why the owners have to repair the soft roof every 2-5 years. We will understand the types of renovation, as well as consider the nuances of repairing soft roofs of various designs.

A soft roof covering has a bituminous waterproofing layer, which thins and collapses over time. Loss of integrity is the main reason for renewal, but the repair technology may differ depending on the amount and severity of damage.

Advice! It is not worth bringing the roof to a state of complete destruction of the outer coating; you will not have to repair, but change the materials. Therefore, it is recommended to inspect the roof for damage every 2-3 years, so that repairs do not cost a pretty penny.

How do you know when it's time for a roof repair?

Delamination of panels in places of overlap / joints;
The appearance of depressions on the panels (water accumulates);
Moss germination at points of water stagnation;
Blisters on the surface of the sheets, indicating the ingress of moisture inside (under the roofing);
Scratches, sheet breaks, cracks are visible coating defects that need to be repaired.

Types of work to renew the soft roof cover depend on the degree of wear of the material and can be:

Restorative / preventive. It is carried out with minor damage to the coating sheets in the absence of a violation of the overall tightness of the roof. A characteristic feature of the repair is local / point renewal of the coating, which can be eliminated without the need for complete dismantling.

Important! Cosmetic renovations are carried out in the case when the total area of defects does not occupy more than 35% of the entire area of the roofing material.

Overhaul- a process that includes the complete dismantling of the material, if necessary, the renewal of the roof structure and the laying of new sheets. In fact, a major overhaul is a new laying of roofing in compliance with all technological subtleties.

Important! Overhaul is carried out in the presence of visible and hidden defects, the total area of which is more than 35-40% of the roofing.

What will be required

Before you start repair work, you should buy building materials and stock up on tools. The calculation of materials for the roof is not difficult: roofing sheets have a certain area, you need to calculate the roof area, divide by the area of \u200b\u200bthe sheets, taking into account the overlap, and as a result, you will get the amount of material needed. In addition, you will need:

Burner, gas cylinder, reducer;
Cutter, vacuum cleaner (for cleaning debris), pipe, spatula, tape measure, rolling stick;
Bituminous mastic;
Overhaul often requires sand, water, plasticizer and cement - to renew the screed.

As for the material, the market offers a lot of options:

the bottom layer can be made from Uniflex, Isoplast;
top final coating - Uniflex, Isoelast, Linocrom.

The main difference between the sheets for covering the upper layer and the lower layer is the presence of a fine-grained protective coating that protects the soft roof from sunlight and precipitation. The thickness of the materials for the top layer should be up to 5 mm, the bottom - 3-3.5 mm.

Roof repair of the current order

The absence of critical damage allows for small-format (point) renovation of the soft roof. It is enough to restore the defective areas of the roof to make the coating airtight and durable. The need to replace areas near water inlets, eaves overhangs will help extend the life of the roof. So, the current repair of a soft roof is the technology of work:

clean the surface of debris, moss and other foreign fragments;
check the sheets for rotten areas - they should be removed by cutting along with small pieces of a durable sheet;
cut off swollen sections of the roof, also grabbing a little durable sheet;
clean the areas freed from the coating, prime and fill with cement mortar;
after the cement has dried, apply patches, pouring abundantly with bituminous mastic over the undamaged edges of nearby sheets;
carry out the fusing of new roofing material.

Advice! Technologically, such work is low-cost, but increases the total mass of the roof. Work should be carried out after a preliminary calculation of the bearing capacity of the structure, otherwise the roof will simply collapse.

Overhaul

In this case, the soft roof is completely replaced with new sheets. The costly procedure is justified by the absence of additional load on the roof elements, the extension of the life of the building and the identification of even hidden flaws. The overhaul of a soft roof provides for the following work algorithm:

Complete dismantling of the old coating. The procedure is done with care, and to reduce complexity, you can use either a machine that cuts the canvas and twists it into rolls, or a long-handled ax.
Cleaning the surface of dust, dirt, cutting out and demolishing worn pieces of the screed, cleaning out bumps, dents - it may be necessary to update the screed completely or pointwise.
Inspection of the hydro-, heat-insulating layer, replacement of sheet pieces. To extend the life of the insulation, it is better to cover the sheets with a dense plastic film or a vapor barrier membrane.
Prime the surface with bituminous mastic.
Starting from the lower edge, lay the draft (lower) roofing sheets, taking into account the overlap of 15-18 cm.

Advice! The greater the angle of the roof slope, the smaller the overlap can be. With an even shape of the structure, the entry of one sheet onto another can reach 20 cm, so that the water retained on the roof does not seep into the lower layers.

Lubricate all seams with bituminous mastic, generously, not sparing the composition.
Lay the top sheets, making the installation in such a way that the joints of the final coating do not fall on the point of the rough seam.
Roofing material, roofing felts are also covered with protective bituminous mastic in order to avoid violation of waterproofing, and it is good to pour fine-grained granite on top of the mastic and compact it properly.

Important! If new generation soft-growing materials are used, granite dressing is not needed. Another advantage of this coating is the adhesive layer at the joints / overlap. This eliminates the use of bituminous mastic - the adhesive composition adheres well and holds the sheets well, preventing moisture from entering.

And to make sure that the coating is strong, take the trouble to make a visual inspection of the roof after the first rain: identifying the most vulnerable places where water accumulates, there is moisture seepage, will require abundant watering with mastic, which will extend the life of the roof and the entire building as a whole.

Note! At one time, the method of additional fusing of roofing material over the old coating was popular. For what, the old layer was removed from the roof only in places of defects, the area was cleaned and warmed up with a burner, followed by coating with bitumen. After that, a new layer of material was welded, sprinkled with crumbs and compacted. The method is very good and low-cost, but the load on the floors should be calculated to ensure the endurance of the entire structure.

Features of the repair of a flat, pitched roof made of different materials

In private houses and buildings where soft roofing is used, two types of roof construction are most often used: flat and pitched. With all the similarities, the technology for repairing a soft roof has some differences. As for similar works, they are as follows:

Cleaning the area from debris;
Cutting out the defective coating;
Screed renewal.

Flat roofs are easy to repair, the process is described above, while pitched ones will require a little more attention. If the soft roof (flexible tiles) is leaky and cracks, swellings appear, they are eliminated as follows:

The upper tile (soft tile) is lifted or removed or a piece of roofing material is cut out;
Apply adhesive to the new tile, smear the overlap with mastic;
Lay a piece of material in place, press and secure, if necessary, with a rail.

Advice! In the case of a complete replacement of the roofing on a pitched roof, the overlaps are made small, since the water, thanks to the steep angle of the slope, leaves quite well on its own.

Membrane roofing is also being repaired. It is done like this:

For roofs with a slope of at least 10 degrees, the installation of new sheets is carried out using fastening equipment;
For roofs with an angle of inclination of less than 10 °, a ballast version is used, in which the membrane roof is sprinkled with any ballast material;
The adhesive version is used for buildings located in windy areas.

Repair of seams is carried out either by welding or by chemical variant. The first method requires special equipment, while the second allows you to repair the roof at any time of the year.

To renew a bicrost roof, you need:

Carefully remove the old coating, being careful not to damage the base of the roof;
Carefully process protruding structures and auditory / ventilation holes with rolled pieces;
Lay new sheets of rolled material on a pre-treated area, carefully smeared with mastic and covered with a rough bottom layer of soft roofing material.

Roof repair soft roof - work, the advantage of which is the possibility of self-carrying out. The preparatory stage includes a visual inspection for the extent of defects, the calculation of the material used and the cleaning of the roof area. It is better to carry out repairs in warm windy weather, but in order for the coating to last as long as possible, experts advise not to clean off the layer of snow to the base, leaving about 5-7 cm of coating. This will protect the roofing materials from accidental mechanical impact.
