What to fill the roof of the garage so as not to leak -
The garage is a sacred place of every responsible motorist, in which the “warhorse” is stored and serviced, as well as a warehouse for those who do not have all the things at home. Although this building is not considered residential, the current roofing of the garage can be a big problem for its owner. Roof leaks are caused by damage to the surface of the roofing material. In this article we will talk about what needs to be done to protect the roof of a garage from leaking with affordable and easy-to-use materials.
Causes leakage
When the roof of the garage leaks, the roof frame and wall decoration suffers from mold and mildew. Leakage occurs due to defects on the surface of the coating through which precipitation penetrates. Most often, the garage roof is made of inexpensive or low-quality materials without the involvement of professional roofers, so the cause of the leakage can be a violation of the technology of construction of the roof. The same defect causes the following damage:
- Cracks. The cheap roll roof, from which the roof of the garage is made, under the influence of temperature drops, is covered with cracks where moisture is seeping.
- Mechanical damage. Soft roofs are damaged by falling branches, stones and debris on the roof surface, as it is damaged as the temperature rises.
- Breaks the canvas. Strong gusts of wind tear down the roofing material, leaving the roof of the garage vulnerable to precipitation.
- Fungus and mold. The harmful microflora softens the surface of the roofing material and can make it vulnerable to leakage.
Important! Many owners of their own garages are wondering what to do to prevent leakage through the roof. To cope with this problem is quite possible on its own without large financial investments. The main thing is to identify the problem in a timely manner and not to postpone the repair on the back burner.
Leak repair methods
When deciding what to do when leaking a garage roof, it is important to correctly evaluate the amount of roofing work. To do this, carefully examine the surface of the roof and identify any defects. The technology of restoration of the roofing sheet depends on the area of damage. Depending on the volume of defects, you can do the following:
- Spot repair. If the damage area does not exceed 10%, then a point repair is made, eliminating minor defects (cracks, holes, mechanical damage). This damage can be poured with bitumen or covered with patches.
- Maintenance. Чтобы восстановить кровельное полотно с площадью повреждений 15-20%, выполняется текущий ремонт с частичной заменой гидроизоляционного материала. Для этого нужно снять верхний, изношенный слой кровли и покрыть новым.
- Overhaul. If the damage exceeds 40%, then perform a major overhaul. It consists in the complete dismantling of the old covering and the laying of the new one. This is the most expensive type of repair, which is recommended to be done 1 time in 10-15 years, depending on the quality of the roofing material.
Remember that regular maintenance and prompt elimination of minor defects - the key to long life of the garage roof. If you perform an annual routine inspection of the roofing sheet, you can save a lot of money on a major restoration of the roof.
Sealing of small cracks
If during the inspection it turned out that the cause of the leakage of the roof of the garage are small cracks that will be delighted on the surface of the roofing material due to temperature drops, then they can be repaired with bitumen. To do this, use solid bitumen, which must be melted, or ready-made liquid, supplied immediately in finished form. The technology of sealing cracks is as follows:
- The surface of a soft roll roof is cleaned from debris and dust.
- With roofing material with the help of skins or grinders with a grinding disc, carefully remove the reservation dressing, which prevents the closure of the crack.
- The surface of the roofing material is degreased with gasoline, alcohol or acetone.
- The crack must be carefully poured with molten bitumen or cold bitumen mastic.
- After bitumen surface drying, the procedure is repeated another 1-2 times to level the surface of the roof covering.
- To protect the surface of the roof from mechanical damage, until the mastic is dry, you can sprinkle it with quartz sand or fine stone chips.
Consider that it is more convenient to use cold bitumen when sealing cracks. Hot bitumen mastic requires careful handling and quick work, while cold is sold in a ready-made form, so using it is easier. To seal small cracks, 1 can of liquid roofing material is enough.
Restoration of the web using patches
Another simple and inexpensive way to eliminate leakage through the roof of the garage is a patch of roofing felt. It is suitable for small damages of the web, localized in different parts of the roof. For patch repair, roofing ruberoid with coarse-grained or scaly dressing, asphalt mastic, knife, varnish and skin are required. The technology of roof restoration in this way consists of the following stages:
- Roof cleaning. The surface of the roof slopes thoroughly cleaned from dust, debris and dirt.
- Training. The surface to be repaired is freed from re-dressing to improve adhesion between the layers, degreased and dried with a building hairdryer.
- Patching. From the roll of ruberoid cut patches, the size of which is 1.5-2 times the area of damage. To patch upright, you need to leave them for 1-3 hours to lie on a flat surface.
- Repair the area you need to fill with bitumen to create a film that improves the bonding of the patch.
- The bottom surface of the patches of roofing material is heated by a gas torch, and then pressed tightly to the roof surface.
- On top of the patch cover 1-2 layers of lacquer or the same bitumen mastic to enhance waterproofing.
Note! For the manufacture of patches, it is recommended to use roofing roofing felt with stone dressing, the density of which is not less than 400 g / m2. It is more convenient to make patches of the roofing sheet using self-adhesive material. Laying the deposited roofing material is performed only at a temperature of +5 degrees and above.
Maintenance
If the roof of the garage is damaged quite badly, then the restoration of the roof is performed, with partial replacement of the blade. In some cases, the installation of a new coating can be done without dismantling the old one. However, if there are blisters and blisters on the roof surface, then you must first remove the upper layers of the roll roofing material, under which moisture has accumulated. In order to qualitatively cover the slope with a new layer of roofing material to eliminate the leakage, it is necessary:
- Remove the old coating. 1-2 layers of worn ruberoid are dismantled, on the surface of which there are a lot of blisters and damages.
- If there are swellings on the roof surface, they must be cut crosswise with a knife, squeeze out moisture and then leave to dry.
- From the surface of the roof remove the layer of dressing. Since the amount of work is quite large, grinding is easier to do with a grinder with a special nozzle. However, it is necessary to act carefully so as not to rub the roofing felt to the holes.
- The coating, from which the sprinkling was removed, is primed with bitumen mastic to create a sticky film that improves the adhesion of the new layer. Ruberoid
- A few hours later, when the mastic grabs a little, you can start laying a new layer of roofing material. Installation of roofing material is performed with overlapping strips on each other by 10-15 cm. The lower layer of material from low-melting bitumen is heated by a torch, and then pressed with a roller over the old coating.
- The second layer of roofing material is laid in the run-up with the first, so that the joints on them do not coincide.
Experienced craftsmen say that the repair of the roof of the garage should be done in dry, calm weather at temperatures of +5 degrees and above. To avoid injury, you must work in compliance with safety regulations and use insurance.
