Safety precautions during roof repair

When restoring the roof, safety is considered above all. Remember that for roofing, a special seasonal equipment will be needed. These are not only respirators and glasses, but also tightly covering the body of clothes, which at the same time does not constrain movements, does not have ties and hanging ends. Mandatory to use mittens from dense fabric.

Roofers need to have nonsense shoes such as felt shoes. And to work on a roll roof, it is recommended to wear rubber boots. Make sure that you have insurance tools: climbing equipment will be the best choice.

The territory under the roof that you will repair, on the ground, is without fail in the right way. If you wish, make a canopy above the ground from a dense film or more durable material to protect your domestic and assistants, since materials, tools and, unfortunately, roofers themselves often fall from the roofs.

The tools should be kept on a special belt. You can also use building scrapes and special stairs that cling to the roof ridge. On such stairs there are special stands that distribute the load of the weight of the roofer with instruments on the roof of a private house. If necessary, you can use additional lining, say, bags with sawdust, sand or paper.

Weather conditions are also of considerable importance. The modern market offers many devices and tools that allow repairing the roof of a private house in any weather. But still, it is better to choose warm dry weather for independent roof repair (late spring or early autumn), when there is no exhausting heat or frost.

Roof inspection for damage

On average, the roof is able to last 40-60 years, depending on the materials. The characteristics of some of them allow us to operate the roof up to 100 years. However, gutters, fasteners, supports, values \u200b\u200band parts of the roof, on which the greatest loads fall, inevitably spoil with time. Therefore, the condition of the roof is recommended to be checked annually, and especially carefully before its repair.

Assessment of the general condition of the roof

Any repair of the roof of a private house should begin with an assessment of its general condition. Initially, you can inspect the roof from the street. Many defects are noticeable at a distance: damaged or shifted sheets of tiles or slate stand out against the background of a whole coating.

If large holes or wide cracks occur in the roof, they differ in color. After that, it is recommended to look against the background of the sky on the rib of the roof so better you can see irregularities. It would be nice to carefully examine the condition of the ends, gutters and adjacents to the ridge, cornices, ventilation ducts and around the chimney using binoculars.

Assessment of the territory under the roof

It is good if you still have made sure that there was safe and convenient access to the roof and repair at the stage of erection of the house: a spacious attic room with good lighting and high -quality flooring, a auditory window, different stairs, as in the photo of the roof of a private house. Otherwise, you need to use a powerful lantern to inspect the territory under the roof.

If the floor is not adapted in the attic, put reliable boards on the beams to walk along them. If the roof is not sheathed from the inside, the rays of daylight will break into the attic, pointing to coating defects. Remove separate attention to the wiring. Any damage threatens with a large -scale disaster. Carefully check the waterproofing, consider the floors, flooring and rafters for the formation of rot and mold.

Even if you remove the foci of decay, the problem may arise again, so it is important to establish its cause. In the case of a pitched roof, the place of leaks can not always be found, because the water often passes above along the slope. When it begins to rot a section that adjoins the support or wall, then, most likely, the problem is in damaged waterproofing.

It also happens that rot occurs due to a large amount of condensate under the roof. This problem can be solved using good ventilation. In the case of infection of the roof, insects require the replacement of the affected areas and the processing of data of wooden mounts using special chemicals.

Identification of roof leaks

It is easiest to identify roof defects in rainy weather. If puddles occur on the floor, and on the walls of the flow, this indicates serious damage to the roof. Sitters of dampness on rafters and ceiling also indicate leak places. During the melting of snow, you can find other problems associated with the roof. At the joints of the roofs, in funnels, yndovs and waste hollows, ice is often formed, which prevents the normal drainage of water. Problems also arise from wet insulation after snowfall or rain.

If the problem areas are clearly visible after the weather, then areas of roofing or joints of the material are damaged. If a leak occurs periodically, and not immediately after precipitation, then most likely there are microcracks in the roof.

The places that seem suspicious to you are recommended to mark in some understandable way so that when repairing the roof of a private house, not to forget. For this, ordinary chalk is perfectly suitable. By outlining the defects in the house, you can immediately find problem areas on the roof.

Selecting the Roof repair methodology

During the inspection, you can detect defects such as mechanical damage to the base or roofing, impaired roof tightness, breakdown or pollution of the drains, which is relevant for flat roofs, cracks, rust, lack of fasteners (screws, screws), and the displacement of the elements of the roofing. Having decided on specific problems, you can decide on a specific type of repair:

Emergency repair consists in local restoration of the most damaged areas and is carried out in places of existing and most likely leaks.
The current repair lies in the planned partial reconstruction of the roof of a private house, the area of \u200b\u200bdamaged areas of which is close to 10-40% of the total space.
Overhaul is the dismantling and replacing significant parts of the roof (more than 40%) with a new coating.

You can replace the reasons for the reasons for serious leakage with new ones, or put on the piles of such material and fix it well. Small cracks that occur on the roof can be poured with a sealing composition, or you can simply glue it with a special ribbon. Methods of eliminating smaller problems are calculated in dozens. In addition, there are differences in the restoration of a new roof and an old roof.

Repair of the rafter system

Capital repair of the rafters of a private house is required only in the case of extensive damage to a rot - more than 50% of the total area. The most commonly damaged areas change. When replacing the rotten part of the element of the rafters after removing the damaged tree, a healthy end should be antiseptic, for example, covered with bitumen. The process of restoring the rafter system should be carried out in several stages:

If the rafter breaks, lay the board on the floor of the attic and install a jack on it, which should be leveled with a broken part.
Attach to the rafters on both sides of the lining that have a thickness of 3.2 - 4 centimeters and length - at least 80-100 centimeters. They should rely on Mauerlat with all the end.
Bind the overlays with long nails to the rafters.
Make four holes on each side, which have a diameter of 16 millimeters.
Put the fasteners in the holes and tighten.

With mass damage to the rafter system, rod prostheses are used. Replacing the rotten parts of the rafter leg is recommended in the following sequence:

Disassemble the roof and a crate on the damaged area.
Install the racks for temporary attachment of the rafters.
Drink a rotten part of the structure.
Put the prosthesis on the rafter leg and put it on the Mauerlat.
Touching the cut end in the supporting platform to prevent sliding.
Check the reliability of the design and disassemble the temporary racks.

After the restoration of the rafters, conduct in the same way the replacement of damaged areas of the Mauerlat. The end of the adjacent leg of the rafters during the replacement is held with a jack. After that, you can proceed to the replacement of damaged parts of the crate.

Roof repair from different materials

Further repair of the roof of a private house depends on the chosen type of roof for a private house and the material from which it is made, and is reduced in essence to the gloss of cracks and joints, covering them with patches, and in case of damage to individual sheets, elements or extensive areas to replace them to replace them .

Repair of a soft roof

Before work, it is necessary to prepare the surface of the roof to remove garbage, mold and dust. The damaged place should be cleaned of the remains of the old roofing and thoroughly dry this place. If the problem lies in bloating, and not in the leak, then you need to open the air bubble, making a cross -shaped incision.

Repair of soft roofs in rainy weather or in winter is not recommended. Even with artificial drying of the roof, the reliability of the work performed will decrease much. To fix the soft roof, you will need a special cold or hot mastic, which is covered with the repair area, after which it is sealed with a patch and is again covered with mastic. You can also use the resin heated to a liquid state.

If there is too much damage on the surface of the soft roof, you should think about overhaul. In this case, it is recommended to completely remove the old coating, and after choosing a roof for a private house, apply a new layer on a pre -dried surface. A similar repair of a soft roof is a more time -consuming and costly process than the point processing of defects and damage.

Therefore, the condition of the roof is best controlled as often as possible, without bringing the roof to complete destruction. Periodically, you need to remove dirt and garbage from the roof, which contribute to the development of dampness and decay. To do this, rinse the roof once a year clean water and treat it with a special mixture from molds.

In winter, it should be cleaned in time from the roof in the roof, and in the fall, monitor the accumulation of foliage with a foliage on the roof. If the trees are located too close to the house, a good idea will be the trimming of some overhanging branches to reduce the number of leaves that are collected on the roof, and protect themselves from branches that fall at the house with strong gusts of wind.

The restoration of the slate roof

The slate is a plate made of asbestos cement, which is different configurations (cramped, flat, wave -shaped) and colors. The main signs that it is time to repair the roof from the slate is cracking and other damage to the coating. If the area of \u200b\u200bdamage is large enough, then it makes sense to replace all the slate. With minor damage, you can repair damaged areas.

The roof must be thoroughly accommodated and washed, let the slate dry. It is better to carry out work on a dry non -fire day so that the glue is quickly dried. Grind the roof with such a composition: 1 \\ 4 parts of PVA glue and 3 \\ 4 parts of water. They proceed to the repair after drying the slate roof. To do this, mix the following ingredients in the following proportion: flooded asbestos (3 parts), frost -resistant water -based paint (1 part) and cement not lower than 300 brand (1 part).

The solution should resemble a thick sour cream by consistency. Do not strive to cook a lot of mixture, do a little, as it dries quickly. Gradually treat all the damaged places of the roof with the solution, pay more attention to places to the joints and fastening the slate to the skeleton of the roof with nails. Go through each damage several times with a painting brush so that the layer reaches 2 millimeters.

Also, cracks in the slate can be sealed with a thick layer of silicone rubber using a mounting gun, and then glue with an adhesive tape made of aluminum foil on top, and after completely drying out the tape suitable in color with the paint. If the slate roof began to knock, then the fastening with nails weakened. In this case, replace them with new ones, or attach them with self -tapping screws with a wide hat.

Restoring the metal roof

On a metal roof, damaged areas are easier to find together. One person knocks with a stick from the attic side in rusted places, and the second is located on the roof outside and notes these problem areas with chalk. If large damage is detected, you will need to replace entire sheets, with medium it is possible to put steel patches, with small fastening of patch from the burlap that are thickly saturated with paint.

There are many options for a roof for a private house made of metal, and their repair has its own characteristics. If the problem lies in the impaired tightness of the seam on the fold roof, the fold must be processed again with a special tool, and then glue a self -adhesive ribbon of rubber or bitumen.

If the coating lags behind in the joints with a pipe or wall, the lagging profile should be removed and replaced with new ones, and all the compounds are smeared with a silicone sealant. If a complete replacement of the sheet is required, then the joints are extended, a new one is laid in the place of the former sheet, after which the seams are bent.

If the roof is made of copper, you can close the hole with a copper patch, and then stock up. There are even special compositions on sale, which allow you to grow out a site of patch, so that it does not stand out against the background of the rest of the sheet. But to solder the patch on the aluminum roof will not work. However, you can attach it over the hole with the help of self -tapping screws and roofing glue.

If the problem is that the material is very worn out and bent, more serious repairs will be required. Most often, the cause of the deflection is damage to the crate. Therefore, it is necessary to make a major overhaul of the roof, dismantling the coating, updating the rafter system and creating a new roofing.

With cracks in paint and scratches on the protective polymer layer of metal tiles, you need to clean the problem areas with a steel brush, remove dust from them and paint over with new paint. The damage sections are usually treated with special anti -corrosion paint.

Repair of natural tiles

Repair of natural (ceramic and cement-sand) tiles requires the removal of the old putty and fill the joints of the roof with a new solution. Such a solution is customary to knead from 2 parts of sand and 1 part of the lime from Pacley. Replacing several damaged plates is carried out in such a sequence.

To begin with, forget the wooden wedges under the neighboring overlying plates and remove the damaged plate, while hooking its edge with a trowel. The plate that is nailed to the rail is removed, turning and raising the tool. If you could not remove the plate in this way, then you need to pull out the nails with a nail with a nail or cut their hats with a grinder.

If necessary, you can replace the roofing material. To do this, remove the nails with which the rails are fixed on the rafters. Under the ends of the deleted place of the rail, put on solid cardboard alternately, cut the slats and damaged roofing material with a sharp knife. Put the patch, which has a larger size than a cut area, lubricating the edges with bitumen mastic.

After that, cut the new rails of a similar cross -section, as well as remote ones, and beat them into the place of old ones. Then you can install a new natural tile, nailing it with nails to the rails. If you need to replace the plates in several rows, work should be carried out starting from the lower rows and moving up.

Thus, you know that the repair of the roof is a responsible matter, and the price of the roof for a private house is rather big. Therefore, you should carefully take care of the coating and check it for damage and deformations. Well, if the roof recovery cannot be avoided, carry out all the work described above in the fall or in the spring, when the weather is warm and dry.
