After careful examination of the wrong side of the roof of her visiting the outside.The first thing to inspect such sites as the roofing system - horse for that purpose whether it is in order if his water resistant layer.Then, the junction of the roof to the vertical pipes and other details - is the most vulnerable places.It is therefore necessary to check the well-metal aprons in these places.Then gradually descend to the valleys - perhaps they are full of leaves and branches, which must be removed, and only after this view element.Cornice Board may from time to time is rotten - so check it, but at the same time trying to find out whether the intact lower part of the cornice.

now remains to explore channels for ventilation and drainage system (for their clogging waste).It is necessary to pay attention to each funnel, gutters and downpipes.Well, the roof slopes can become a haven for mosses and lichens - in this case they need to be eliminated.In addition, look if there are any bubbles on the cover of the roof, dents, holes or chipped cracked.In fact, many companies involved in the repair, have in their arsenal of infrared cameras.With their help you can quickly find leaks, and check the entire system.Then, on the basis of the data produced calculation of the necessary amount of work and materials.

mesto-protechki discover and understand the cause of leakage pitched roof is sometimes very difficult.This is due to structural features of the roof, because the water can flow into one place, and leaks appear in completely different places.

most common roofing disease

Most often the roof leaks due to the following reasons:

# 1. violation of the integrity of the roof.

# 2. can develop leaks roofing joints of walls and vertical elements such as antennas, pipes and railings.

# 3. Another common problem is the breakdown or failure of the drainage system.

All these problems occur for the following reasons:

  • If fasteners and coating material for the roof have the dubious quality, they do not last for long.
  • In addition, possible violations of technology when installing roof.Because of this, there are excessive load, disrupting the roof.When
  • inaccurate removal of snow or ice from the roof and gutter can damage them, after which they begin to fail.
  • moss and fungi, settled on the roof, too spoil it, and in some cases the destruction process can be much faster than you can think.To avoid this you need to make timely maintenance of the roof.
  • destruction of the time - even very high-quality and well-constructed roof the roof, lay on the roof long enough to wear out, requiring replacement or repair.

As you can see, in theory, everything pretty simple.But in the real world to find a place leaks to repair the roof of the house is not always possible to quickly.Sometimes a drop of water to get inside the house when the wind blows out the side, driving under the roof of rain or snow.It often happens that drips from the ceiling is not where the water gets inside the house.In such cases it is better if the entire roof "roofing pie" tested by professionals.

Repair roof system

On rafters holding the entire roof, they assume the load from the weight of snow, streams and rain and wind gusts of course the severity of the roofing material.If the rafters are damaged, do not procrastinate.The problem needs to be solved immediately.

damaged areas removed paneling, insulation and roofing, dismantled crate.If truss support rotten, well cleaned the wound site.Then stuffed with two sideboards 80-100 cm long and 3-5 cm thick.Attach their long nails.It also happens that a piece rots the rafters to the core.Then it needs to be cut and install rod prosthesis 2 or 2.5 times longer than that of the rotten rafters.On its edges give it a trim.The whole structure is connected nails length of 10 or 15 centimeters.While there are works under the rafters con temporary stands, but after the prosthesis rod will set them clean.

Repair of rafters
Two ways to repair rafters.

There is another option - the rafters tselehonkim but crate damaged and it is not under the force of gravity of the roof.Eliminating cracks and deflections replacing battens or its amplification.For this purpose between the rafters and beams placed laterally packed board.

Tips:

# 1.All patients of the rafters after removing them burn.

# 2.Peeled areas promazhte antiseptic.

Replacement and repair of thermal insulation and waterproofing layer

Because of leaks can get wet insulation and as a result loses its insulating properties.In this case, it needs to be changed.However, sometimes it is caused by a change that he, though intact, but not enough to keep warm.When viewed from the inside of the roof, the roof pie consists of the following layers:

  • First comes the waterproofing membrane,
  • then - insulator (mineral wool, as a rule),
  • Next - vapor barrier.

Last made of polyethylene, glassine, foil materials paroneprinitsaemyh membranes.

Insulated roofing pie
example roofing pie for roofing shingles.It consists of roofing materials (shingles), waterproofing, two layers of basalt wool and vapor barrier.

In case of damage to insulation work to be enough, but to repair the roof of a private home can be his own hands.To do this, remove the paneling inside and get to the vapor barrier.Taking off her, the probe heater, checking if it is wet.All wet heat insulator plates need to pull out, replacing dry.Dobravshit waterproofing to check its integrity.If it is a whole, settle this film back if damaged - change.This waterproof membrane should be laid so much so that it skirted the rafters, so it fasten them with nails or staples.

insulation boards are cut so that they have turned increasingly to 1 centimeter than mezhstropilnoe distance.Putting them slightly compressed and then placed between the rafters.Straightening, insulation will not fall - it will hold tight.The joints between the first and second insulator layer should not be combined.If the second layer does not fit, increased thickness trusses plates.Stuffed to the rafters nails, pull them over the cable insulation uteplitelem.Poverh lay a vapor barrier with overlapping 7 to 10 centimeters, securing the stapler.

When repairs need to be removed and damaged, and the neighboring tiles.First of all - the top, then - side.Driving a wedge under the tiles next to it is necessary to pick up the edge of the extracted tile with a screwdriver (or a trowel).New tiles are placed evenly, taking care of the tightness of joints.

Leaky Roof Tiles

If the cracks in the coating of small, it is possible to seal them.Raising tile roofing adhesive smear it on the inside, and then pressed to the plane of the base, holding the place of gluing a few minutes.However, it happens that the cracks in the roof very much - then it is better to change it.Pulling the nails to the desired location it is cut, then inserted a sheet of tiles.The edges are aligned.Work at zero temperature - from 5 to 25 0 C.

When more damage the slate changed.To do this, a sheet of which needs to be replaced completely take out the nails.On neighboring plates, which press the sheet nails completely removable not reach, but only lifted above.It is necessary to adjacent sheets have started to rise and allowed to get damaged leaves and put a new one.By the way, the manufacturer gives guarantee on the slate - up to 15 years.

mend gutter system

usually drain starts to flow when the tightness of connections broken.This often happens in winter time, under the influence of snow and ice.Therefore, if the system is made of PVC, all elements are usually connected to dichloroethane adhesive or rubber gasket.If you want to change them for seals of EPDM.But the bonds replace more complex: it is necessary to cut a piece of pipe, and then paste the new one, using the same glue.

individual elements of metal gutters are usually fastened with rivets that the replacement parts necessary to drill the drill.Replace worn parts, riveting them together and applied to the joints of silicone sealant.

Drain Cleaning

sealing joints with ventilation and chimneys

These locations (outputs ventilation chimney, dormer windows and antennas) require special attention and monitoring.Their joints need to cover up roofing adhesive.Suitable and special sealing tape.Also, there is an option - to close these places plates with decorative trim.And then after a repair the roof of a country house, and become a strong and elegant.
