Professional repair of soft roof. How to properly repair a soft roof with a special technology how to repair a soft roof

D. avaite Let's look into the eyes of the sad truth - the repair of a soft roof, flat, the roofs of rolled materials required much more often than I would like. But everything is not so bad! If this repair, follow according to the requirements of the technology, it will last at least ten - twelve years, and even longer. Here we will look at how to repair a soft, rolled or flat roofThe most common damage, the methods of their elimination. As well as learn the destructive factors leading to the damage to the coating.

What is and how to repair a soft roof

To begin with, it is necessary to understand what is and from which consists of a soft, rolled roof, in order to determine the nature of the damage and the necessary measures for repair. Soft roof (it is flat or roofing from rolled materials), called it because the protection against moisture serves as a layer of flexible, "soft" materials produced in the form of rolls. They are the basis of cardboard, glass cholester, tissue, on top of which layer bitumen is applied.

The name "flat" such a roof received due to small slopes (3-5%), in contrast to, from sheet and piece materials. Read more about You can learn by reference.

The main methods of laying a rolled roof are:

1. gluing on bitumen mastic;
2. Pointing by gas burner, or by a different device, creating a high-temperature jet of air.

However, the differences in the methods of the soft roof device are belonging to the final stage of work - laying the roll carpet. The cut "sandwich" of a soft roof consists of the following layers (see Fig. 1).

1. Base. The base serves the design of the overlap. It can be reinforced concrete plates (panels), wooden or metal flooring.

2. Parosolation. It is arranged in the presence of insulation. The task of vaporizolation, protect the insulation from vapor moisture.

3. Insulation. Beneficable, rigid insulation (clay crushed stone, chunk or blastine slag, foam concrete), less often plates from a rigid miniclift. This layer often suite the necessary roof slope.

4. Screed. Creates a solid, smooth "shell" on top of the insulation, to stick the actual rolled carpet. It is performed from the cement-sandy solution of the brand 120-150. To increase the strength, the screed is often reinforced by a wire mesh having a cell 100x100, 150x150 mm from a smooth wire of 2.5-3 mm.

5. Primer. It serves to increase the adhesion of the cement screed. It is made of bitumen and solvents. The primer can be made independently, mixing the molten bitumen with diesel fuel in a 1: 3 ratio. Instead of diesel fuel, for reduction, apply inexpensive oil. For example, transformer, "axial", spent motor. Bituminous primer is known as the "primer".

Today it is considered one of the most popular roofing materials used both to cover private houses, baths, garages and for multi-storey building. Roofing covers in this group include piece and rolled products made on the basis of bitumen and fiberglass. The undoubted advantages of this material are simplicity of laying, high noise, hydro and thermal insulation. Unlike working with other coatings, the technology of repairing a soft roof will not require high time and labor, which completely allows you to produce all actions yourself.

Possible defects of soft roof

For timely prevention of unpleasant moments associated with the integrity of roofing, the roof of the house must be periodically examined for such damage as:

• swelling;
• the appearance of fungus, moss and rotting in pits, cracks that promote water accumulation;
• detachment in the zones of the adolescent and places of docking of material cloths;
• mechanical defects as a result of contact of the roof with stretch marks, antennas, branches, ice.

To increase the life of the soft roofing coating, it should be at least twice a year to conduct outdoor surveys in order to detect and timely eliminate visible defects. The roof needs regular purification from branches, garbage and building materials left on the roof after the construction of pre-rod structures, in order to avoid possible consumption in the roofing canvas.

Choosing materials for the repair of a soft roof, it is recommended to pay attention to the most popular types of their:

• for the upper layer - uniflex, linocur, isoplast, isoelast (have a service life for more than 10 years);
• for the bottom layer - Breprext, glass eelast, technoelast (differ with elasticity and create additional thermal insulation).

The materials for the upper layer must contain a mineral powder in its composition to protect against solar radiation, their thickness ranges from 4.5 to 5 mm. The thickness of the materials for the lower layer is from 3 to 3.5 mm.

Choosing mastic

Laying the upper layer of soft rolled cloth is made using a bitumen-polymer material forming a solid elastic coating capable of withstanding mechanical and temperature deformations of the base. Mastic for repairing soft roofs can be used both in cold and hot.

Cold mastic (bitumen and ruberoid) is used to repair the inner layers of the roof, hot material (only and delet) - as an outdoor coating. The prerequisite is the content in the mastic of bitumen and the mixture of dust-like type, for example, gypsum, lime and ash.

Carrying out the repair of a soft roof with their own hands, you can also independently make bitumen mastic. The cold mixture is formed as a result of mixing one portion of filler with two bitumen portions and the same amount of gasoline. You can mix the components only after the bitumen is completely evaporated until 180 degrees. Next, the mass is cooled and takes directly to work.

To prepare hot mastic, you will need a boiler in which the bitumen needs to heat up to 200 degrees, slowly adding the filler. In the process of mixing, the temperature should not be descended below 160 degrees, otherwise the bitumen mass will be low quality.

It should be remembered that the preheated bitumen needs to be poured into gasoline, and in no case is not gasoline in bitumen! Stir the contents of the boiler is necessary for a wooden stick. Bituminous mastic is not intended for long-term storage, it is necessary to start working with it immediately after cooking.

Features of the repair of soft roof

Before repairing the soft roof, the roof surface is visual inspection to determine the scale of work. Distinguish three types of repair:

1. The current aimed at eliminating small defects of the roofing canvas (cracks, holes, separated joints).
2. Capital - necessary when the current repairs are not able to ensure proper waterproof of the roof.
3. Emergency - produced as a result of leakage, or after unforeseen damage to the roof surface.

To remove small holes and cracks, the defects are poured with bitumen mastic, stick a piece of rubberoid, after which the additional bitumen layer is applied on top. The connection of the separated joints is carried out like this: the material is raised, the space under it is dried with the burner, then the bitumen is applied to the dry area, and the material is again lowered. The problem junction is once again treated with mastic.

Overhaul of a soft rolled roofing is carried out according to the following scheme:

• worn coating is removed;
• the cement screed is restored and, if necessary, it is placed heat, vapor and waterproofing;
• the new roofing material is stacked.

To eliminate the possible accumulation of water on the surface of the roof, it is necessary to pour it with water, mark the plots where the water is not glass. Bend the water and dry the roof, after which the marked places to pour hot mastic or lay an additional layer of rubberoid thickness not more than 1 mm. The final stage will be the laying of the upper layer of the roof, followed by the special composition on it, neutralizing the negative impact of the external environment.

Before starting restoration work, it is necessary to prepare the following equipment for the repair of a soft roof:

• gas burner (heat the coating is also a soldering lamp, but in this case the workflow will significantly delay);
• ax or mounting cutter for dismantling old coating;
• a sharp knife for cutting material;
• maclavitsa for applying primer and bitumen mastic;
• broom or broom to remove garbage.

Carrying out roof repair in winter, to the listed equipment should be added a wooden shovel to clean the surface of the roof of snow. Do not forget about overalls, without gloves, shoes and working pants from dense fabric, it is not recommended to start work.

An important condition for safe operation with a gas burner is to use safety glasses.

Innovative trends in the repair of a soft roof

Seasonal temperature differences entail the destructive consequences for a soft coating, leading to cracking, bloating and destruction of the roof sections. Applying outdated ways, the need for partial or overhaul roofing canvas occurs once every 1-2 years, bringing with you additional costs of dismantling the old and acquisition of a new material. The technology of repairing soft roofs using liquid rubber is a relatively new and secure method, widely used in modern construction.

Innovative technology makes it possible to eliminate the current and overhaul of the roof for a period of about 30-50 years due to such high-quality indicators as:

• safety - a two-component emulsion on an aqueous polymer-bitumen basis is applied by special equipment by the method of cold spraying, excluding the emergence of a fire during construction work; The substance does not contain harmful volatile compounds;
• durability - material applied to the surface, almost immediately pouring, forming a reliable rubber membrane, resistant to high and low temperatures;
• high elasticity - the limiting extension coefficient of the finished coating is more than 1000%, which gives this material with the ability to "self-upfulness".

The new technology for repairing the soft roof of the house has long gained popularity in foreign construction companies due to the absence of shortcomings inherent in the outdated method based on the use of soft bitumen coatings. Liquid rubber can be used both on flat and on scanty structures, and the simplicity of the application of the canvas allows you to produce all work without resorting to the help of professionals.

The roof in a private house can normally serve on average no more than fifteen years. Of course, this is possible only when compliance with all the basic rules and norms when it is installed. During the operation of the roofing coating, it is possible to periodically arise in conducting certain repair work.

What sequence should the roofing measures be carried out?

First you need to determine the presence of defects that need to be corrected.

With visual inspection, pay attention to such moments as:

• Presence of gaps in the joints of the joints of the roofing substrate;
• Existence The roofs of the visual pits and depressions, which are places of cluster of rainwater and moisture;
• Detection of discovered areas on the surface of the roof. This fact indicates water and moisture to the protective roofing layer;
• Reveal the places of emergence of rot and mold;
• Visually evaluate the root For cracks and deformation of roofing surface.

Technical inspection of a soft roof of a private house must be carried out every year, it is desirable to do this in spring and autumn. As early as possible detection of damage places, it will correct the defects in a cheap and quick way.

The real estimate of the technical condition of the roof will help conclude the type of repair required for this roof.

Types of roofing

Roofing works may be the following types:

• Emergency roofing repair;
• Current repair activities;
• Overhaul of soft roof.

Emergency work Provide an urgent need to restore the roof of a private house. Usually, these works are included in the replacement of roofing in places of leakage. Recovery activities covers up to twenty percent of the total area of \u200b\u200bthe roof.

Current repair It covers about forty percent of the entire area of \u200b\u200bthe soft roof. It is best to exercise it every year after a preliminary visual inspection.

The following work may include the following work:

• Partial replacement of spoiled roofing sections;
• Events for posting temporary payments.

The need for major repairs It occurs in the case when it is necessary to restore more than forty percent of the soft roof area. In order to fully bring to the norm of all operational characteristics, the entire coating of the roof is carried out or its largest part.

Usually, the sharp need to perform restoration work is associated with partial destruction of the bitumen layer, which threatens a decrease in the hydro and vaporizolation properties of the roof, and this, in turn, means that water and moisture from the outside will begin to leak into the residential premises.

In the event that it is planned to independently perform roofing work, it is necessary to study some literature and develop a plan for building events.

How to choose roofing material

It is necessary to know that low air temperatures are extremely negatively affected on certain types of roofing material. It is necessary to choose only the material that will not break into strong frosts.

Roofing specialists advise to use the following types of materials:

• A variety of soft tiles;
• Professional flooring;
• Metal tile.

Features of creating estimates
repairing soft roof

It is very often possible to hear the view that the estimate should be made only during capital work on the repair of the roof of an apartment building, a garage or other buildings. In fact, this is not so. The estimate is needed when carrying out any repair, as it is necessary to calculate both the volume of work and the price, the cost of the repairs carried out, the price of the service.

In the estimate it is necessary to register each stage of repair work, and the number of necessary material accompanying this stage.

Thus, it is possible to bring the following approximate list of repair activities:

• Removing the coating that has come into disrepair. This can be done both on the entire area of \u200b\u200bthe roof, and only with damaged areas;
• Work on the preparation and stripping of the roof surface to accommodate a new layer of roofing;
• Installation work with a soft roof;
• Measures to seal joints;
• Work on the creation of the upper waterproofing layer.

The repair estimate needs to lay the costs of acquiring both consumable and combustible materials. It is necessary to take into account the costs of delivering the necessary materials.

To facilitate the calculation of the desired number of building material, you can use the photo image of the roof repairable. In the event that it is difficult for them to make a true estimate, you can contact these issues to specialists.

Current repair of a soft roof of a private house

The current repair of a soft roof can be carried out in two ways.

First method

Repair work consist in creating "payments" on damaged areas of the roof, as well as in connecting the separated seams.

The latter of defective sites is the following events:

• All spoiled areas of roofing material are removed. They can be cut completely or pierced;
• Roofing surface is covered from all types of garbage;
• The roof area, which is damaged, is filled with a sealant or bitumen mastic;
• On the layer of mastic top, the front-end leaf is stacked, which in its size should be more repaired zone.
• The bituminous layer is again superimposed on top of the runneroid, which is distributed evenly throughout the leaf with the help roller.

The elimination of defects on the floor roof is performed using polymer-bitumen rolled coatings and gas burners.

Second way

In the event that it is only required to connect the separated seams, then the following manipulations must be performed:

• Gently raise the separated sheets, without taking them off from the roof itself, and try to dry them thoroughly;
• Soak the area of \u200b\u200bdamage to the bitumen layer;
• Return the roofing sheets to the previous place and on top, on the docking seam, put bitumen.

Overhaul of soft roof

Sometimes it happens that the roof is so running that no patch and processing will be saved. In this case, you have to make a major overhaul of a soft roof. Such works will be based on the full replacement of roofing material on the entire roof area.

The estimate, compiled on the overhaul of the soft roof, with this development of events, will increase several times.

When carrying out overhaul roofing, the following works will be performed:

In the event that there is a need to execute all listed activities, the cost of repair can be several times to exceed the cost of normal installation.

It is also necessary to note that even the most ordinary overhaul of a soft roof is as follows:

• The soft roof is completely changing and partial repair is made;
• A thorough revision is produced, as well as a partial replacement of spoiled roof sections.

How to check the quality of the completed repair work?

The main question, which is puzzled by the owner of the house, in which the roof is repaired with the involvement of specialists, is how to check the quality of work.

When checking, you should pay attention to the following:

1. It is necessary to conduct a visual inspection of the repair point;
2. Sheets of roofing material must be laid smoothly, without visible distortions, spreads and intersections;
3. To assess the edge of the roof. They have to fit tightly to the roof, so that they could not disrupt the strong impulse of the wind.

Repair of a soft roof in winter

Repair of the soft roof of a private house in the winter cold period is not recommended. But often, it is precisely during this period defects, and they must be immediately eliminated.

Repair work in winter needs to be carried out taking into account the need to comply with increased security.

In this cold and unfavorable time of year, it is possible to produce repair work only in the following cases:

• If the roof of the household unexpectedly underwent extremely serious damages that could happen because of the strong blizzard, hitting the roof of a very large and high-speed subject;
• In the event that due to the large amount of atmospheric precipitation in the form of snow, there was a roof deflection;
• A sudden thaw led to the occurrence of water leaks.

It is quite obvious that each of these situations may well entail more serious consequences, as a change in the initial state of the roof and wall overlaps. In addition, a short circuit may occur and burning the roof itself, and then at home.

In order to avoid terrible consequences, of course, it is necessary to restore the normal state of the soft roof.

Safety in execution
Roofing work independently

When performing repair work on the restoration of the soft roof, it is necessary to follow the following rules:

• You need to pre-think all the necessary uniforms. It must be convenient and without a large amount of vane and straps;
• It is necessary to take a particularly careful about the choice of shoes.. It must have a non-slip surface;
• In winter, days short and quickly darkens, Consequently, we need to think about it in advance how to light the roof, otherwise you will have to interrupt the work immediately after dismantling the roof at the place of damage;
• You should take a first-aid kit with youso that if necessary, to provide first aid;
• Before repair work in the winter It is necessary to clean the surface of the roof from snow and sleep. For this purpose, you can use a rubberized scraper;
• Future wagged material, it is necessary to keep in a warm room until it is used;
• Absolutely any capital work It is necessary to carry out a soft roof to repair with a partner. It is not recommended to hardify the roof. Installation of a new roof can be tried to carry out with your own hands, but it is just unable to repair one.

Innovation in the repair of a soft roof of a private house

Recently, an innovative technology for repairing a soft roof is still applied. It lies in the fact that liquid rubber is used as a repair material. This method of repair is relatively new, quite safe. It eliminates the need to re-access a specialist for subsequent repairs.

Rolled roofing materials based on modified bitumen - a practical solution for the country house, a city cottage, a garage or other business buildings. They are characterized by high waterproofing properties, weatherproof, affordable price and long service life. The main advantage of this option is the convenience of mounting, thanks to which the roofing works can be performed with your own hands. In addition, rolled materials are unfounded in service. In this article, we will tell how the current and overhaul of the soft roof required for the working condition of the roof is performed.

Roofing materials based on a modified bitumen are considered the most resistant to the outer environment of coatings. However, intensive exploitation and lack of timely service do not remain non-traced. Repair of a soft roof is performed if the following damage is collected:

1. Cracks. As a result of multiple temperature drops and the exposure to cold, the surface is covered by cracks, through which water seeps inside the rafter frame.
2. Mechanical damage. Rolled roofing materials based on bitumen are easily damaged when branches or drops of stones on the roof surface.
3. Frams of the finish layer. Intensive wind load leads to the breakdown of the upper layer of the roof, which will lead to leaks and further destruction.
4. Wear. Each roofing coverage has its own service life and comes to disrepair from the constant effects of water, temperature and wind.
5. Edit. Under the influence of atmospheric moisture, rolled materials become a "victim" of mold microorganisms or fungus, which leads to reinforcing coating.

Important! If even minor defects are detected on the surface of the roof, which do not yet cause leaks, it is necessary to fully repair the soft roof to avoid further destruction of the design.

Types of recovery

The effect of external environment factors has a negative impact on, gradually leading to complete wear or destruction of the coating. Repair of a soft roof - the inevitable stage of the roof operation, which sooner or later have to go through each homeowner. There are 3 varieties of restoration work:

Please note that the point restoration is the easiest, cheap way to restore the roll coating with your own hands. To constantly monitor the condition of the roof, it must be interpreted regularly. Only the everybody inspection and sealing small defects will help save the coating in excellent condition.

Point recovery technology

Point restoration is performed when damage occupies no more than 15% of the roof surface. In this case, you can close defects with peculiar patches, which will prevent the appearance of leaks and further destruction of the roof. To repair a soft roof with your own hands, you need:

1. First, it is necessary to view the roof surface and circulating detected defects with a white chalk.
2. In places, damage must be made of a cross-shaped incision to squeeze moisture from under the finish coating.
3. Then you need to sand damaged surface and degrease with alcohol or gasoline.
4. On the processed surface, you should apply bitumen mastic and give it to grab.
5. Then you need to stick to the surface of the roof the patch from a roll material, the size of which is 20-30 cm more defect.

Experienced masters claim that rolled materials are well reduced. Small cracks on the surface of the roof close even with a liquid rubberoid.

Capital reconstruction technology

Overhaul of the roof from rolled materials is a technically complex process that can be performed only in the presence of special equipment and the experience of roofing work. It is produced if the proportion of damage exceeds 40%. The technology of repairing a soft roof consists of the following steps:

• First, a complete dismantling of the old roofing coating is performed. Remove all materials to a concrete base.
• The base of the roof must be cleaned from garbage, pollution and fat, and then thoroughly dry the construction hairdryer.
• Apply to the roof of the roof bitumen masting with a roller, a sprayer or brush.
• After drying the mastic, laying a new coating. First, 1-2 layers of the lining material are mounted, and then the floor layer flooring is performed.

Installation of a soft roof is performed using a gas burner, with which the bottom layer of the material is heated, and then glued to the base. Roofing with bitumen materials are performed in dry, weakening weather at a temperature of +5 degrees.

Experienced masters and manufacturers of roofing materials noted that the timely maintenance of the roof is the key to the "healthy" state and a long construction service. Therefore, do not neglect the daily inspection of the surface of the skate and timely detection of defects.

Video instruction

Mosstroykrovlya offers services for the repair of a soft roof. The soft roof is widely used to overlap the roof in the construction of multi-storey buildings, private houses, trading halls, industrial facilities, garages, baths, etc. For the production of roofing, materials made on the basis of bitumen and fiberglass are used.

Defects of soft roof

For cities and settlements located in the middle lane of Russia (they include Moscow and the Moscow region), the period of operation of the soft roof rarely exceeds 5 years. Especially the roof suffers in the winter.

To prolong the period of use of a soft roof, scheduled checks should be carried out for damage.These include:

• The formation of air or water bubbles.
• The appearance of fungus and moss on the roof surface.
• Disposal in places docking cloths.
• Mechanical cracks and gaps as a result of contact with trees, ice, antennas and stretch marks.

As mentioned, winter is the most destructive period for a soft roof, so the planned test is recommended to be carried out before the cold starts, to remove the leaves and branches from the roof, and carry out the local roof repair.

Varieties of the repair of a soft roof

1. Current or directed repair - so roofers call the elimination of small web defects. As a rule, at current repairs, no more than 20-40% of the coating area is replaced.
2. Overhaul is a complete replacement of roofing. It is made in cases where more than 40% of the area of \u200b\u200bthe canvas needs in replacement.
3. Emergency and urgent repairs are produced when leakage is detected.

How much is the repair of a soft roof

The price list for roofing works can be very different, since repair brigades and companies independently determine the cost of work. The price is influenced by such factors: the condition of the canvas, the roof device (straight, oblique, complex forms), the choice of material for overlapping, waterproofing, the deadlines for the end of the work and the qualification of the roofers. Only a wizard can determine the exact cost of work, after estimating the condition of the coating and measurements of the roof area.
