How to repair a roof from roofing material

If the roof roof flows, and the patching of damaged places did not bring tangible results, then the only right decision remains to carry out a complete replacement of the roof, provided that the roof is overlapped in good condition. The easiest way to repair a single -sloping roof is from roofing material, but to block the steep roof of the extension or garage, which adjoins the house, will, apparently, is more complex, but not hopeless. Although the price of the roof of the roof of the roofing material is both in the first and in the second case is quite attractive.

Features of the roof roof

The roofing material is called building roll material, which belongs to waterproofing materials and is a roofing cardboard, which is impregnated with bitumen on each side in several layers. Ruberoid is available with various sprinkles.

The new modification of this material is a self -adhesive roofing material. Its lower part is a self -adhesive layer that does not swim and is covered with a protective film. During operation, this film is quickly removed so that the adhesive does not have time to dry, and is well crushed to the roof.

Ruberoid has gained great popularity when arranging roofs of various buildings thanks to its advantages, which are predetermined by such material properties:

1. High water resistance - roofing material does not get wet for 72 hours;
2. Excellent heat resistance the material does not swell at a temperature of 80 degrees for 2 hours;
3. A high water absorption rate level of moisture absorption by roofing material is no more than 2%;
4. Low deformity on the bend of material at a temperature of plus 25 degrees cracks are not formed;
5. Greater strength is the basis of modern roofing material is reinforced, which gives the material increased strength;
6. Resistance to aggressive chemicals and ultraviolet radiation;
7. Excellent flexibility this property preserves this roofing material at very low temperatures;
8. The low mass of the cover composition is 500 grams per 1 meter square;
9. Cheapness. The price of roof from roofing material is perhaps the lowest among all roofing materials.

The need to repair the roof from roofing material

Today, roofing material is most often used as a waterproofing layer in a roof pie. Thanks to its high waterproof properties, the rooferoid found application at construction sites with an increased level of humidity. They are also customary to cover wooden buildings before installing the roofing. But, despite the advantages of roofing material, this material can last no more than 5 years, and after this period it has to be repaired.

Ruberoid is widely used as the upper layer in a roof pie. However, his appearance is quite unpretentious, so most often it is chosen as a budget material to cover household buildings, old village houses and country houses. In this situation, the main enemy of the roofing roof becomes ice, or rather the methodology of its removal: it is customary to do this mechanically in us, with the help of a steel scrap, which, along with ice, removes the entire roofing.

On flat roofs of multi -storey buildings, roofing material is also often used, although it is not intended for waterproofing operated roofs. But it is most often chosen instead of a more suitable and strong material due to cheapness, not even trying to find out how to replace roofing material on the roof. In this case, the material is even faster from walking on it, say, people who control the condition of elevator shafts, antennas, advertising structures or air conditioners. And again, there is a need to repair the roof from roofing material.

Squeezer of repair of roofing roof

At the end of the time of spring rains or before the onset of autumn, the roof is covered with roofing material, it is necessary to inspect the subject of defects. If such are found, you need to start repairing roofing roof. Receptions by which repair work is carried out depend on the level of damage and their overall sizes.

Elimination of cracks

The roofing roof, which does not flow, but is covered with small cracks, should simply be thoroughly dried, cleaned of garbage and pollution and covered with hot mastic. At the same time, bitumen consumption is approximately 1.2 kilograms per square meter.

You can eliminate small holes as follows. To begin with, clean the place of damage itself and the area around it from pollution and mastic of the substance, with which roofing material is fixed on the surface of the roof. The smallest holes you can simply plunge with a specially prepared putty: mix the preheated bitumen mastic with dry sawdust and sand.

The mastic for repairing a roof from roofing material is more preferable than just a warmed bitumen, since in its recipe has a complex of plasticizers and other additives that improve adhesion and a number of coating indicators in a cold season and in humid weather.

The parapet will prevent the removal from the roofing roof of foliage, branches and other garbage. But when repairing the roof with the material with the material, the ingress of this garbage under the roofing coat inevitably provokes a violation of the integrity of the waterproofing carpet or the formation of air bubbles.

Repair of small damage

If the damage area is large, then a patch made from a piece of roofing material should be applied to this site. One side of the material should be generously lubricated with the same mixture. But at the same time, one difficulty may arise. In the manufacture of roofing material, both of its surfaces are treated with special sprinkling, which gives it additional strength and prevents the process of gluing during storage of roofing material in rolls.

This property of sprinkling, which consists in counteracting gluing, leads to the fact that the patch is not too simple to apply the patch on the roofing roof. Therefore, you need to first remove the surface layer from the roofing material. If this is done without preliminary processing, then you need a lot of effort.

Such processing is as follows: apply a layer of solar oil on the roofing roof or brush and wait a while. Then you should arm a spatula better to take a wooden tool so as not to damage the lower layers of roofing material, which are the main ones, and scraping the sprinkle with careful movements, which will become soft and supple by this moment.

A similar repair of the roofing roof can be carried out exclusively along a dry roofing material, so if you can’t wait until the roof dries naturally properly, then you should use the hairdryer. It is also important to observe the correct technique for applying adhesive mastic on a patch. Do not do too thick layer it should be uniform and thin, for which you should use hard brushes or brushes.

If you did not guess the amount of mastic, and the excess mass was squeezed out of the edges of the patch, then it must be filled with a spatula in such a way that its frozen layer is not thinner and not thicker than the roofing material itself.

Repair of through holes

With more serious defects, for example, through holes, a more thorough repair of the roof roof is needed. In this case, make a cross -shaped incision on the roofing material, and the corners that turned out to be in its center, bend to the sides, completely exposing the roof. The freed area must be carefully processed: cleaned of garbage and dirt, tear off the old dry mastic.

Then you need to fit a new piece of roofing material in size, also removing sprinkling from one side and smearing with an adhesive composition prepared according to the technology described above. There are two such large patches. Stick one patch from the roofing material directly to the surface of the roof, and then grease the bent angles of the roofing material with mastic and lay them in the same place, gently smoothing them.

On top, apply a second patch that should be covered with an even layer of mastic. Process not only the roofing patch itself, but also the surface near it. So that glued pieces do not be exfoliated from the roof of the house, they should be pressed with boards or bricks, and on top of the patch should be sprinkled with sand.

Roofing the roof of the house by roofing

Often it is required to carry out a complete repair of the roof roof, which consists in removing the old coating and laying a new roofing material. Remember that with the help of roofing material you can repair only roof roofs or old carcass roofs.

Preparation of the base

Before equipping a new roof on the roof, you need to dismantle the old material that has lost its adhesive properties to the base or has many mechanical damage and stratification. Also, all garbage and dirt need to be removed from the roof.

Very often, in such works, resin is used, on which roofing lanes are glued. Under the influence of environmental factors, after a while, the resin begins to crack. If it is not removed, then water will soon begin to accumulate in cracks. Therefore, it is worth carefully removed the entire tar on the roof under the roofing material.

If your building has a pitched roof, then you should arrange a solid crate before laying the roofing material. To do this, it is customary to use a non -cunning and chopped board, CSP and OSB plates, as well as plywood. If the pitched roof was previously blocked by roofing material, you should check the existing crate for decay, fungus or mold, remove the detected defects or clean the local areas and cover with special impregnation.

If a reinforced concrete slab was used as an overlap, then the roof should be cleaned to concrete. On the basis of there should not be large bugs and potholes. All recesses should be sealed with a polymer mixture. If there is, on the basis of significant irregularities, it is necessary to make a screed with a slope in the direction of the drain, which is created by increasing the thickness of the screed by one centimeter per linear meter, must be made in dry weather. To do this, use a regular water or laser level.

Application of mastic

When the concrete grabs, you need to remove all the garbage with a broom and apply mastic with a roller or brush. Remember that for working with mastic, screed and in general roofing material, rainy weather does not fit at all. On a raw surface, you should not take any action, because the release of the material will certainly happen. Choose a clear, warm and sunny day.

Mastic of various compositions, so you should see on the label the period of its setting and the conditions of use (temperature and humidity). Do not rush to overlap the roof by roofing roofing, it is necessary that the applied mastic must dry out and grasp the surface a little.

Laying roofing material

So that work with roofing material does not deliver to you, it should be kept in a detailed state for a day. If this cannot be done, just rewind the roll in the opposite direction. Before laying the roofing material, you must first cut the roofing material into pieces of the required size.

After the mastic has dried up, you can begin the process of laying roofing material. At least two layers of roofing roofing roofing should be laid. You must use for the first layer a grocery material without crumbs, and to create a second coating with stone crumbs. The required number of layers will depend on the degree of the slope of your roof.

On flat roofs, it is recommended to make at least 5 layers. If the slope of the roof up to 15 degrees put 4 layers, if the angle of the roof is 20-40 degrees, make 3 layers if the inclination of 45 degrees and the above 2 layers of the coating is enough. There are 3 methods of laying panels, let's look at them:

1. Placement placement across the inclination line. In this situation, it is recommended to start work from the cornice and make sure that each row lies on the previous one with an overlap of 10 centimeters. Water is guaranteed to get into the seams.
2. Coating with roofing material along the slope line. In this case, water will drain along the panel and will not be able to flow under the seams. The side overlap is also made about 10 centimeters. The work is carried out from the pediment, and the overlaps are made on the leeward side so that the predominant winds do not lift the exfolved coating.
3. Using the first two styling methods. The lower layer is laid according to the first methodology, the top in the second, and vice versa.

If you have chosen the first or second method of overlapping the roof of the roof by roofing, then lay the material so that the seams of the layers do not match. On the pitched roofs, the flooring of the panels across the ramp is most often used, since in this case you can throw a piece of roofing material through the horse, fixing at the top, and then below.

Gluing roofing material

To glue the roofing material on the base, a gas burner is required, with which the roofing material is heated along with mastic. The sheet of material laid on the roof is heated until the upper film turns and burns. This signal suggests that both roofing material and mastic are ready for gluing.

The heated strip must be well pressed to the roof, gently smoothed and ride with a special hand rip to high -quality sticking. If there are irregularities, you should manually achieve a high -quality fit of the panel to the surface of the roof. This can be done with a regular rag. Do so the site behind the site.

If deep potholes occur on the surface, then you cannot roll up such a surface with a rink. As a result, in those places, condensate will occur over time, which will provoke the spoilage of the roof. Therefore, once again we recall that before laying the roofing material, the surface must be carefully prepared.

If it is not possible to avoid irregularity, roofing material in such problem areas should be pressed to the roof with any improvised means. This rule is recommended to strictly perform, since the material should fit tightly to the base.

In this case, it is recommended to carefully monitor the heating procedure. If you warm up very hard, then roofing material can melt. Therefore, before repairing the roof from the roofing material and directly glue the panel, you should practice a little on small pieces. Keep in mind that the second layer can be started only after the first has completely freezed.

To ensure the insulation of the vertical elements of the roof pie, for example, pipes, mines, chimneys, it is recommended to start 40 centimeters close to them to a height. And after gluing, additionally pressed with a special clamping bar, which is well fixed to the base of the parapet.

Places of spilling funnels and other nodes that require a cut of roofing material should additionally be strengthened by shreds of roofing material in 2 3 layers over the cut. It is very important to glue the sheets to the edge of the roof, otherwise the panel will tear off the wind. To ensure greater reliability, it is worthwhile to fix the roofing material from the edge of the roof with wooden or metal racks.

Now you know how much it costs to block the roof by roofing roofing, and how to correctly repair the roof using this material. The procedure for flooring on the roof of roofing roofing material is not very complex even for an extraordinary builder. If you correctly perform all the stages of work, the roof will receive an elegant elegant look, the coating will serve faithfully for many years, and you will not even know what the roof flow is.
