Roof - the most vulnerable of house construction. It is the most exposed to the external environment: sunlight, precipitation and mechanical stress. This is especially true of country houses, since most of the year they are unattended master and no one in a timely manner to clean snow or troubleshoot the problem.

Requirements for the villa roof
In order to properly and quickly close the roof at his dacha,you need to find answers to the questions: what should be a roof and how to block it in the simplest way? Let's see, what characteristics should have the optimal roof Cottage:
1. It shall be sufficiently stable to environmental effects:
- Moisture - the house must be moved to the absence of the owner and the rains and snowfalls;
- To the sun: heating the roof, they are strongly heated and the interior is home to the hottest time of the year;
- Mechanical stress - a strong gusty winds and abundant snow load.
2. Must have an aesthetic appearance as long as possible, because no one wants to carry out its repair annually.
3. There should be inexpensive, since it is hardly worth a lot of money to invest in a place of temporary (seasonal) rest.
Checking the condition of the roof
Update leaky roof does not mean thatjust replace the old roofing material on the new one. If the roof is operated a couple of decades and if it is periodically flowed, then before you begin you need to check the condition of the entire roof construction, namely:
- truss system;
- waterproofing layer;
- thermal insulation materials;
If you plan to cover the roof of a new (other) roofing material, the crate should be changed in any case, because of the correctness of its creation largely depends on the quality of installation work.
To re-roofed roof was qualitative,should be updated, and a layer of waterproofing. And if the house will live in the winter time - be sure to change the insulation. For this perfect Basalt mineral wool.
Particular attention should be paid to checkingtruss system - "skeleton" of the roof, in fact it has to withstand the weight of the crates, heat and waterproofing layers and roofing. If the leak occurred, then most likely, the rafters are traces of rot, so they need a partial or even complete replacement. And, although in the latter case, the owner of cottages have pretty invest, he will receive in return an opportunity to change completely if desired appearance of the roof: pick it, change configuration, to arrange the attic or increase the size of the attic.
Dismantling of the old roof covering
Before starting the overlap of the roof in the countrythe dismantling of the old cover and, if necessary, truss construction. The first step is to remove all of the roof antenna, wiring and chimneys. If the roof was covered with sheet metal, their removal is carried out using a hammer, a screwdriver or a crowbar. Change should also ebb and roof.
Roller old coating is cut into strips witha knife, scissors and then special. Cut strips separated crowbar from the roof and roll to roll. If the roof has an indoor slate, its dismantling begins with removing the ridge elements. The fasteners are removed a claw hammer or screwdriver. Asbestos sheets begin to withdraw from the ridge of a number of horizontally. At the end remove the overhangs made of steel and the valley.
If the roof was tiled, in the first placeremove the ridge shingles and then move horizontally to the eaves. Pre-need to cut of mounting wire. For ease of movement laid the running boards. To disassemble the rafters and lath used axes, saws and a crowbar.
Choosing a new roofing material
Choose the type of roofing on the basis of the requiredcharacteristics, it is not difficult, because now in DIY stores presented a lot of modern roofing materials differ in structure, properties, method of installation and cost. Slate is not used as often as before, because it became clear danger to health if improperly handled with him. Moreover, it is quite fragile and unattractive in appearance.
Replace it can be other corrugated sheets (onBitumen) - Ondulin. Large assortment of metal roofing: corrugated board, metal, steel sheets. The roof can be covered with a modern and attractive soft roof or the classical natural tile or imitating its polymer. It looks natural tile, of course, solid, but it is not often used for cottage roofs, because it is cheap and weighs a lot. Vacationers prefer simpler materials. Let us consider a few of them.
Installation of metal
Metal - very popular todayroofing material. This is a beautiful and reliable coverage weighs little, is resistant to aggressive environments, UV rays and corrosion. The material is easy to cut, drilled, mounted. If the choice fell on him, the old roof is completely dismantled, removed sheathing and waterproofing layer. Leave only the truss.
Metallocherepichnoy roof refers to the lungsroofs. Through profiling sheets are characterized by sufficient rigidity, so to fit them do not need a continuous sheathing. New crate made of bars 40x40 mm and 400 mm. When it is necessary to align the bracket sag.
To secure the crate using a staplerspecial anti-condensate film, recommended by the manufacturer of metal. It is moisture and absorbs it, subsequently evaporating. Then conducted styling metal.
Galvanized steel - often used inRussian roofing material. It is easy to operate, relatively inexpensive, allows you to create any geometry of the roof. The roof of the roll or sheet steel mounted on the standing seam technology: Connect cover elements carried creating special seams - seams. The limbs can be single and double, erect and immobile. The most waterproof and airtight double Roofers consider standing seam.
The slope of the roof when using technologystanding seam joints - more than 14 degrees. If the slope is less, a mandatory need to make a solid base with a double fold and seal with silicone sealant.
Traditional standing seam technology devicesroofs with special hammers displaced today a new technology, using power tools, which significantly increases the productivity and quality of the seams.
Features overlapping roof Ondulin
Unlike many roofing materialsondulin has pronounced noise-attenuating properties, and it is important in the regeneration of the attic on the roof. With a relatively moderate cost it is very durable. The material is soft (made of cellulose and fiberglass), it can be cut normal saw or jigsaw for wood. Therefore crate underneath it is recommended to do with frequent cross-section, which will provide ondulin required rigidity, thereby improving its resistance to snow loads in winter and summer rainwater.
Laying Ondulina made horizontalbottom rows. His laid overlapping in the "checkerboard" procedure, which would give additional stability to the whole structure of the wind gusts. For Ondulina are special nails, if they are not, or not enough to complete their re-buy at the rate of 20 nails on one sheet. In the first row are fixed each wave of the material, and in the subsequent rows nails already slaughtered over one wave.
The roof of a flexible (asphalt) shingles
The basis of shingles - fiberglass, whichimpregnated and coated with a special bitumen roofing. On the inside of the tiles a layer of self-adhesive bituminous mass, and from the outside - a layer of topping that gives the material the desired color.
When installing shingles each tile is securedfurther lapped to the base using roofing nails. The layers are gradually sintered tiles in the sun, forming a completely tight roofing. As shingles also relates to a light roof, under her crate and waterproofing do the same as under the metal.
Shingles come in different versions - withhigh frost resistance and resistance to fire. For example, for the northern regions can be selected from bitumen shingles SBS: it is easy to tolerate temperatures in the range -35 ° - + 110 ° C.
Overlap the roof garden was not any easier thanconstruction of a new one. Here, the right choice of roofing materials is important to combine with a competent installation to update the roof served and decorated with your favorite summer residence for many years and, most importantly, without repair.
