Evroshifer, metal tile, soft tile

The last decade was marked by the active promotion of a number of new roofing materials. One after the other in the marketplace took evroshifer, metal tile, soft tile, surpassing traditional roofing materials. Today's story - about one of the "new friends" - bitumen, or, as it is called, soft tiles. Advantages of a roof - is, first of all, simplicity of service, as well as durability, resistance to wind loads. Preserving dignity evroruberoyda, soft roof, unlike the material, has a beautiful appearance. Shingles is almost waste-free does not rust and rot (she was not afraid of any pests) and is suitable for simple surfaces, and for roofs that contain complex architectural elements. Finally, a small proportion of the material (depending on the manufacturer and the components used, about 9.12 kg / m 2) allows the use of lightweight truss construction, a variety of shapes, colors and shades - to achieve a unique solution for each individual home. Tiles produced various forms: in the form of a hexagon, rectangle, triangle, oval, wavy, etc., and has lots of colors. COMPOSITION AND CHARACTERISTICS At first glance, this material is nothing new - soft tile is shaped pieces of glass fiber or polyester fiber (base), impregnated with a binder on a modified bitumen basis, and, in fact, not very different from evroruberoyda (except that the geometry and , respectively, in a manner fasteners). In fact, the systematic improvement of the properties has led to a qualitatively new product, rightfully popular zastoyschikov. That modifier determines the stability of the roofing material to heat, cold and ultraviolet radiation and is responsible for increasing the life of a soft tile compared to the "grandfather" - the usual ruberoydom. Most-modified bitumen APP (atactic polypropylene) and SBS (styrene-butadiene-styrene). Speak of the superiority of one over the other additives is difficult. Say, heat APP higher than SBS, but at the same frost SBS higher than AMS. In addition, partially protects against UV rays and broadcast with decorative - a layer of basalt or mineral granules. The greater percentage of the surface, closed crumb, the more durable tile. And, of course, should be broadcast with a good hold on the surface - otherwise it would negatively affect not only the appearance of the roof, but also its durability. The bottom surface of a soft tile, usually partly covered with sand, a layer of partially self-adhesive bitumen. The latter is responsible for the leak and the roof membrane is protected by plastic film, which is before the assembly should be removed. To soft roof served for a long time, the area of ??adhesive layer must be at least 15% of the surface area of ??the shingles. Otherwise, sufficient tightness will not be achieved. As a rule, with one pack soft tiles can cover an area of ??the roof of 3 m2. In this case, a standard size sheet - 1000h337 mm, number of pages in the package - 21 pcs. Dimensions and weight of one package are small - this material can easily be transported in the trunk of an ordinary passenger car. BLOW-soft tiles can be used as a roofing material for the pitched roof of at least 100. The exact value of the manufacturer specifies in the passport on the product - for different brands of tile, it ranges from 100 to 120. Although the installation of shingles is relatively easy, on the other hand, it should be applied to all technological procedures with special attention and care. On this depends the life of the roof. But on the maximum angle constraints for soft tile no. This material is safely tolerate vertical fasteners, for example, for lining the vertical elements of the roof or walls. For the installation of soft tiles to smooth, dry and clean solid foundation that can be made of OSB, plywood or moisture resistant edging board with a moisture content less than 20%. The thickness of the base is chosen depending on the distance between the rafters. At the same time for additional waterproofing used roll of lining materials. The use of continuous or partial sealing depends on the slope of roof slopes. With a slope ramps up to 30 °, depending on the type of tile, underlay is laid across the surface of the roof in rows parallel to the eaves, with a longitudinal overlap of 10 cm, cross - 20 cm in slope over 30 ° waterproof enough to pack in the valley (curvature of the roof) , along the eaves, around chimneys, dormers, as well as in other places likely cluster of rain water or snow. Waterproofing it is desirable to seal the seams with mastic asphalt. Shingles Shingles are laid in rows from the bottom up, starting from the center of the lower ledge in the direction of the gables. The first row is placed so that the protruding part of the roof tiles covered the joints and cut line eaves tiles. When installing the next row right ledge covers location joint between two shingles of the previous row. Need to periodically check the straightness of the board or cable laying. At the edge of the gable eaves tile is cut flush with the edges and glued roofing mastic to a width of 10 cm Mounting shingles to the ground with a slope of 10-60 ° is carried out mostly with galvanized roofing nails with smooth, wide hats (the diameter of the nail - 3-4 mm cap - 10 mm c step - 8-10 cm). Each shingle is secured four nails so that nail pierced and the top edge of the underlying shingle. With a slope greater than 60 ° is recommended to use 6 nails. To remove the protective film from the adhesive layer is necessary before mounting the next shingle to provide a dense and uniform adhesion of shingles, as well as good quality glue joint. If done correctly, after a while formed a monolithic layer of the roof. Temperature during installation shingle roof should be above 5 ° C. The soft tiles can be installed only in dry weather. LIFE Lifetime roof depends on the durability of roof and supporting structure. At the same time we must not forget that all elements are inextricably linked with each other, so that the loss of properties one of them will affect the service life of the roof as a whole. The use of synthetic materials causes a limited lifetime shingles. The warranty on soft tile is typically 15-30 years. This is less than for natural tile or copper roof, but if the shortcomings of the above materials (a lot of weight, high cost, complexity of installation), then the option of using soft tile may seem more attractive. The producers believe that the real life of a soft metal and is approximately twice the warranty. Whatever may have been a remarkable roofing material, if wood base underneath rotten, the roof would stay a long time. That's why all the wooden structures (trusses) before the assembly is necessary to process the special products that protect wood from rotting and the effects of pests.
