Shingles

One of the special types of roofing - shingles is a form of a soft roof and consists of a flexible asphalt shingles on top sprinkled with rock dust. This kind of coverage has eye-catching appearance and long life (30-40 years). Aesthetic properties of the soft tile in no way inferior to the ceramic, but it is significantly cheaper. Modern shingles made of the latest technologies. Basis of shingles - fiberglass or fiberglass, on which both sides suffered oxidised or modified bitumen. On the right side and cause a stone or mineral crumb, which gives the coating a variety of colors and protects it from climatic influences, and is detrimental to bitumen of UV rays, ensuring a long period of operation. The underside of the plates of shingles is a layer (usually more than 50% surface area), modified bitumen self-adhesive, protected by a special silicone film. Modified bitumen - is not destroyed and does not flow when temperature drops, and provides a low fire hazard of a roof. Synthetic base - glass fiber or polyester, which provides the geometric and physical stability of the shingles from rupture or other damage. Stone chips - made from special types of stone, which do not absorb moisture and therefore do not crack. Can be painted at high temperatures and does not change over time, its color. In addition, the shingles belongs to the category of light roofing - her weight is 11.8 kg/m2. Since shingles is a piece material and does not form a completely continuous coating, it does not require flexibility in as much as roll materials. Deformation of the material (aging) are limited to each individual tile, which eliminates the tampering with the coating on the internal stresses. Laying the roof - a delicate matter and requires certain skills. roof - an important component of safe houses. That it is strong and durable, it is important to know the many nuances of the installation process. The minimum roof pitch, which allowed the use of shingles is about 12 degrees. When installing on slopes of 12 to 18 degrees to the device special carpet underlay. The maximum slope is not limited to - installation is possible even on the roofs of adjoining vertical sections of the walls. As a basis for shingles used material from a solid flat surface, which can be fixed with nails. For example, can be used sheets CAP, water-resistant plywood (PSF), or rebated, edging board. Humidity of material for the base should not exceed 20% of dry weight. Start the installation of the base unit of the roof with the training grounds. The base must be smooth, hard and always ventilated. The air gap must be large enough exhaust hole have as high as possible, and the air intake, respectively, in the lower part of the roof. Remember, properly executed ventilation is the key to long life of the roof. Ventilation is necessary for: removal of moisture from insulation, sheathing and roofing material to prevent formation of ice and icicles on the roof in winter, reducing the temperature inside the building during the summer. When the snow load 1,8 kN / sq.m., A point load 1,0 kN step sheathing, mm board thickness, mm thick plywood, mm 600 20 12 900 23 18 1200 30 21 In the case of tile installation at temperatures below +5 ° . C, packing material before installation should be stored in a warm room. Installation of underlayment as strengthens underlayment under the tile roof used carpet. Necessary to lay underlay their skates on the eaves and in the end parts of the roof. With a slope less than 1:3 underlay is installed over the entire area of ??the roof. Underlay mounted bottom-up approach with overlap of at least 10 cm, the seams are sealed with glue, the edges are fixed with nails at intervals of 20 cm Mounting of cornices If the design of the roof requires a spillway system, mount in Cornice strip of roofing brackets for mounting the gutter. Lay on the eaves, as well as all the end parts of the roof over the underlayment curtain steel sheets overlapped 2 cm Fasten them zigzagging roofing nails every 10 cm, and expansion joints at intervals of 3 cm through both sheets. When assembling the end parts instead of metal curtain sheets can be used triangular strips or strips of wood. Next, mount the cornice adhesive tiles (tile size 1x0, 25 m, mounted without overlapping), after removing them with a protective film. Fasten the eaves tiles at a distance of 3-5 cm from the top edge with the interval between the nails 20 cm layer of tile installation Laying soft tile should be started from the eaves towards the end parts of the roof. The first row of shingles lay so that the lower edge of the tile was located at 5.3 cm. above the lower edge of eaves tiles, and the protruding part of the tiles covered the joints eaves tiles. Glue the tiles, having removed them from the bottom of the protective and nail four nails each slightly above the groove soft tiles. If the roof pitch steeper than 1:1, each soft tile must be attached with six nails. Subsequent series mount, so that the ends of the reed plates are flush with the cutouts of tiles of the previous row. At the end parts of the roof shingles, trim the edge and seal the adhesive to a width of 10 cm for direct seams between tiles, use markup chalk lines on welds. Installation of roof penetrations Roof penetration of small diameter - ND fans, antennas, etc. performed with rubber seals. Smoke and other pipes exposed to heat should be insulated. When installing tiles near chimneys or other penetrations in the place of the pipe with roofing nail on the perimeter of the triangular rail. Soft tile rewound on a vertical surface and stick adhesive. On the perimeter, pipe okleyte with a continuous layer of adhesive so that the top tube was covered by no less than 30 cm Close adjacency metal apron and seal the joints with glue. Junction with the vertical walls are performed similarly. Montage skate skate assembly is done by ridgetile (formed by dividing Cornice strip shingles, the amount of 0,25 x0, 33 m.). Each cornice tiles should be divided into three parts to the places of perforation. Glue the tiles, after removing the film on the short side parallel to the ridge ridge. Fasten the four nails per side so that the nails were to overlap of 5 cm, the next tile
