Description

The utility model relates to construction equipment and can be used to repair the roof by pouring it with hot rubber-bitumen mastic. The use of mastic for repairing roof roofs allows avoiding seams, an unreasonable number of joints, irregularities, and the use of a mastic roof allows you to get a seamless roofing membrane over the entire area of the reconstructed roof section. At the installation for the preparation of modified rubber-bitumen mastics, such mastics are obtained, made of bitumen, in which substances are added to combat brittleness, to increase the softening temperature of high molecular weight chemical compounds consisting of homogeneous repeating groups of atoms, which ensures increased durability of the roof being repaired.

Roof repair

Roof repair is a necessity that sooner or later every homeowner faces. There is no doubt that this part of the building must be strong, airtight and reliable. The roof serves as a house protection not only from atmospheric precipitation, but also from excessive heat loss.

The roof of the roofing material must be coated with bitumen mastic. A new roof requires such a grease only after five years, and the subsequent grease depends on the degree of wear of the roof. For lubrication, liquid mastics, heated and cold, are sometimes used. The range of such mastics is quite wide.

Roof coating should start from the highest place and gradually go down. If necessary, too dry roofing can be smeared twice and sprinkled with sand on top. If there are bubbles in such a roof, they need to be cut crosswise, unscrew the edges and remove the mastic from the base. Then, you need to cover the place with fresh mastic, attach a piece of roofing felt under the turned edges, grease again and glue the cut corners. If a patch is applied, it should also be coated with mastic. According to the parameters, the patch must go beyond the seams, and not less than 10 cm.

The backlog of the roll roof can be eliminated as follows: cut only along the roof ridge and stick its lower part to the base. Then you need to cut a strip of roofing tape (20-30 cm wide and in accordance with the cut part length). Mastic should be applied from top to bottom on the base and lower part of the roofing, and from bottom to top on the upper part. A strip of roofing paper is inserted into the hole. In order to eliminate holes in the roll roof, they must be sealed with patches from pieces of roofing felt. The base is lubricated with mastic. If there are too many holes, the roll roof should be cleaned, a fresh coat of mastic applied and a new coat of roofing laid. Laying is best done in the direction of the slope of the roof so that the edges of the pieces are overlapped. Firmly press the layer to the base to avoid bubbles. Roofing is attached to the edge of the roof with steel strips, so that the coating does not break even in strong winds.

Sheets in slate roofs crack for various reasons. For example, excessive pressure of the mounting screws that attach them to the base, or underestimation of the diameter of special holes designed for mounting screws. Errors in the transportation and storage of slate sheets in warehouses are also common reasons why you should start repairing the roof. In order to fix these malfunctions, it is necessary either to replace whole sheets, or stick on strips of damaged fabric with special mastic soaked in places where there is damage. It is necessary that the fabric overlaps the damaged area by at least 10 cm. In order to avoid the appearance of new cracks on the roof, when repairing it, it is necessary to use stairs and transverse overlays to move.

Repairing the roof of steel sheets must be done in cases of rust, since subsequently it can cause leaks. In order to avoid them, it is necessary to rinse the place where the rust occurred, first with kerosene, then with water, and then clean with sandpaper. Then you should cover the place with linseed oil, after drying, apply a primer and oil paint of the appropriate color.

The tiled roof needs repair if cracks have formed in it. Strengthening the roof structure is possible by knocking down the rafters with boards. In the event that mortar has crumbled from the joints of tile tiles, it should be replaced with fresh, laying it between the tiles from the attic side.

Depending on the severity and type of damage, major and current repairs are distinguished. Maintenance is appropriate if regular preventive maintenance is carried out. Major scheduled / unscheduled repair of a solid roof is the most ambitious and time-consuming event. It implies reinforcement or full / partial replacement of the supporting structure, its individual elements, most often it is only about replacing the partial / full roofing material. Repair of metal roofing material is carried out mainly due to the appearance of rust, which inevitably leads to the formation of leaks. In order not to take it to extreme measures, experts recommend that you clean up the formed holes, cracks from rust, then by sealing, patch with pieces of galvanized steel or similar material. If the roofing has undergone significant undesirable changes, a serious and long-term repair is ahead, which should be approached professionally.

Roofing from roofing material, roofing felt and other soft materials at its low cost is not durable. The roofing coating needs annual scheduled repairs for the first three years, then every 3 years. Strengthen the surface by applying mastic specifically designed for this type of work. A ruberoid roof in this regard is more problem-free, requiring lubrication only after 4-6 years. Mastic is used preferably bituminous. However, such a roof is also susceptible to damage (brittleness) during the winter cold season and sharp temperature drops. Membrane roof repairs are less common due to their properties. This type of flat roof has a wide selection of colors, reliable and durable, has excellent waterproofing characteristics. In case of violation of the surface of the coating, detection of leaks, the specialists of our company will repair at the highest level with strict observance of all the necessary requirements for this type of roof.

Soft roofing may be affected by:

- Mechanical stress - static, seismic loads. It does not tolerate hail, heavy rains and water vapor pressure.

- To physical influences. The destructive effect is exerted by water in all its aggregate states (steam, snow, hoarfrost / ice), air currents, infrared, ultraviolet and other radiation.

- Chemical exposure. Fungi, molds, chemical compositions and solutions corrode the surface over time.

Soft roofs are repaired more often than metal and tile, because they are inferior in technical and strength characteristics. The most common soft material damage is:

- aging of mastic with subsequent softening;

- delamination complete or partial from the screed;

- tears and microcracks, the appearance of bubbles.

Preventive lubrication should be carried out mainly from top to bottom. It is recommended to apply mastic in two layers before and after applying a patch (or seam), which should not go beyond the seams by more than 10 cm. Maintenance of a soft roof is carried out if the damage covers no more than forty to sixty percent of the soft surface. Thanks to the professionalism and wide experience of our masters, leaks will be eliminated, the coating is updated in a short time and for a moderate payment.

Overhaul is carried out in case of damage, occupying more than sixty percent of the surface layer. The soft roof has its own characteristics, for example, flowing rain / melt water moves along a “winding” unpredictable path. Therefore, before starting repair work, the roof undergoes a thorough inspection to determine the true location of the leak.

It is worth remembering that quite often resort to repair due to improper installation. Having decided to save money, customers turn to “professionals” who do not pay due attention to the technology of laying materials, processing joints, etc. Only cooperation with professional specialists will not only extend the life of the roofing, but also reduce your money and time costs for upcoming repairs. And unpleasant emotions from unplanned repairs remain in the memory for a long time. Installation and repair work must be carried out in accordance with GOST standards, safety regulations.

The main part of the house is the roof, located on the outer, upper surface. It is she who, from day to day, directly perceives the effect of all atmospheric phenomena - wind, precipitation, temperature, insolation and protects the house from the effects of these factors. The roofing device is made using various materials. In this article we will talk about such an independent material as mastic for the roof, and the features of the device and repair of the roof with this coating.

Mastic roofing

Mastic roofing is performed without the use of rolled materials, and mastics are used as an independent roofing. A necessary condition for such a roof is a uniform distribution of the material on the roof surface. Mastic is applied manually or using a spray. The subsequent layer is applied after the previous one has cured.

Spray application of mastic

For better durability, mastic roofs are reinforced with a mesh of durable fiberglass or a fiberglass cloth. These materials have high mechanical strength. The basis for the roof can be a cement-sand screed or reinforced concrete slabs. In the joints of the roof elements with vertical walls, cement mortar boards are installed.

Before applying the mastic, the sides and the base must be primed. A mastic carpet is created on the roof in 2-3 layers. The eaves overhang, ridge, groove and valley at the junction with the roof are reinforced with an additional layer:

- the ridge is reinforced with a layer of mastic 60 cm wide, reinforced with fiberglass or fiberglass;

- reinforcement of the valley, cornice overhang and groove is carried out in two layers with reinforcement.

Basically, the number of reinforcing and mastic layers depends on the slope angle:

- device of mastic roofs with a slope of 10% - mastic coating in three layers, reinforcing pads - in two layers, an additional protective, gravel layer is arranged;

- slope of 15% - mastic carpet and reinforcement is carried out in two layers with a coating of the upper layer with gravel;

- 25% slope - mastic coating in three layers, reinforcement in two, the top layer is covered with paint.

Such roof elements as valley, skate, eaves overhang are strengthened until the main mastic carpet is applied.

The joints of the roof with protruding vertical parts and walls are strengthened after covering the base of the roof. Top is covered with gravel. The thickness of the reinforcement is about 8 ... 10 mm.

Reinforcement of mastic increases the strength of the coating, but reduces its elasticity.

Types and properties of mastics

Mastic for the device and repair of the roof

Roofing mastics are represented by a wide classification series:

- polymer;

- bitumen-polymer;

- bitumen-latex;

- bituminous.

They have such properties:

1. elasticity;

2. light weight;

3. high strength;

4. resistance to solar radiation;

5. stability when used in an aggressive environment.

To change the properties of mastic under conditions of a certain need, the use of various fillers is used, which affect the elasticity and strength of the material.

In this regard, mastics can be used on various surfaces:

- concrete;

- steel;

- ruberoid.

This material can act as an independent coating or adhesive when roofing using rolled materials. Mastic for roof repair is also used.

Mastics differ in the number of components that make up their composition: one-component and two-component. The basis of a one-component mastic is a solvent. When it evaporates, the composition on the roof acquires a solid, elastic state. Such mastics are available in ready-to-use form.

The scope of mastics is wide enough:

- covering new roofs;

- repair work on old surfaces;

- arrangement of junctions of shaped elements, horizontal and vertical surfaces;

- sealing and folds;

- protection of the roof surface from environmental influences;

- waterproofing of roofing.

This mastic refers to a bitumen-polymer coating. It can be applied under pressure or manually. The thickness of one layer is 2 mm.

It can also be applied by filling with subsequent uniform distribution over the entire surface. Mastic resists moisture after one hour after application. Two-component mastics at release are represented by two compounds. When used, they must be mixed, which allows you to change the properties of the material according to real, building requirements.

Depending on the application, cold and hot mastics are distinguished.

Hot application is a more laborious process.

Bituminous mastic

Bitumen-polymer bridge

Mastics of the cold application method include bituminous mastics, which are a roofing insulating material that protects the roof surface from radiation and precipitation. Bituminous mastics include a mixture of petroleum bitumen and various fillers, which reduce the brittleness of the material, increase its strength, elasticity and heat resistance.

Bituminous mastics in their mixture may contain various components.

In this regard, they can be divided into such groups:

- bitumen-polymer;

- rubber-bitumen;

- bitumen emulsion.

These materials are used:

- for repairing almost all types of roofs;

- waterproofing surfaces;

- for anticorrosion treatment of metal roofs.

This mastic has a rather thick consistency, therefore it is suitable for sealing horizontal cracks and seams. Mastic of this brand does not contain toxic solvents.

Bituminous mastics prevent the penetration of moisture under the roof and the growth of plants in the roof sheet. When applied, the surface must be clean and dry.

Cold mastics

Mixing and applying cold mastics

Cold mastic roofing, prepared for the roof on a diluted binder. It is suitable both for the roof covering device and for vapor barrier or gluing of rolled materials.

Organic thinners (volatile and non-volatile) are used to dilute cold mastics to the desired consistency.

Volatile diluents, in turn, are divided:

- aviation and automobile gasoline;

- White Spirit;

- lighting kerosene.

Non-volatile diluents include:

- lubricating, transformer and machine oil;

- liquid bitumen;

- fuel oil.

Many cold mastics are produced on the basis of bituminous pastes with the addition of antiseptic substances and mineral fillers. In this case, water is used as a diluent.

Such mastics are not suitable for gluing rolled materials on the roof, since bubbles and bloating form under the roll roofing carpet as a result of evaporation of water. Therefore, cold mastics, which are based on bitumen paste, are used during repair work on the roof to seal cracks and seams and to apply a new layer on a clean surface.

Application of mastic by filling method

Before use, mastic cold roofing is thoroughly mixed. In accordance with the requirements of the application, it is diluted with various solvents.

You can work with roofing mastic in conditions of low temperatures. To do this, it is necessary to warm it in a room at a temperature of over 15 degrees for 24 hours.

Before applying the mastic coating, ice, snow, dirt, and deformation coating should be removed from the surface. The porous surface of the roof before applying bitumen mastic is treated with bitumen primers.

If the manufacturer has not indicated in the technical specifications the possibility of applying the mastic on a damp surface, then it is necessary to dry the coating area before using it.

Mastic is applied with a brush or trowel, when filling it is leveled with a mop.

Permissible measures for the use of this material:

- lack of precipitation;

- temperature conditions over minus 5 degrees.

Hot bituminous roofing mastics belong to flammable materials, therefore, work with them is carried out in the open air, away from the source of fire. When working, it is necessary to use protective clothing, in order to avoid contact with mastic on the skin.

Roofing on roofs with combined structures is often affected by water vapor, which rises and forces the roofing to "work" on the gap. At the same time, the mastic for the roof, due to its ability to adhere to the roof panel, provides it with reliability, tightness and strength. The installation of roofing systems, the provision of waterproofing, the laying of roll cover, and the sealing of roofing deformations with mastic becomes much easier.

Despite the large assortment of imported roofing mastics and imported installations for the production of hot mastics, their cost is very high. Therefore, the design of the most simple installation based on the trailer is proposed.
