In order to make a good roof, which reliably protects the house from any bad weather, you need to take care of its weak places, such as the cornice and side overhangs, valleys, the abutment of the roof to walls and pipes, the place of mating with the attic windows.
Even the best roof does not provide protection to your house, if you do not take care of them. Armor for these areas is, so-called, additional elements that can be purchased from the manufacturers of roofing materials.
The additional elements can be universal (standard) or manufactured by special order. Standard equipment is usually sold complete with roofing covering in order to avoid mismatch in size during installation.
Addition to softness
Roofing is known to be made of various materials: polymer-bitumen rolls, ceramic, cement-sand, bituminous and metal tiles, metal galvanized sheets, etc. Each type requires its own additional elements.
There is an opinion that the soft materials are not needed. Say, they are flexible, and so repeat the irregular relief of the roof elements. This is not entirely true. The Gryphon Roofing Company happens to be the best in this.
So, one only flexible roof tiles do not qualitatively “trim”. It will take another lining carpet, which is a roll bituminous material, usually on the same basis as the soft tile itself. Its purpose is additional waterproofing of the roof and protection of the most problematic nodes, as well as smoothing of possible unevenness on the roof (for example, joints of sheets of plywood). Lay the underlay carpet over the entire roof, or around the perimeter, as well as in the problem areas described above. The first option (over the entire surface of the roof) is preferable, and with a small slope of the roof is even mandatory.
To equip the valley of the flexible tiled roof, a special carpet is used. Carpets for the ends are produced by all companies; however, if some manufacturers insist on their application in the areas of convergence of stingrays at an internal angle, others offer a carpet only as one of the ways of laying the valley, along with overlapping ordinary roofing soft roof tiles.
- The edges of the bottom carpet are glued to the bituminous lining and are fixed with nails. In addition, with the help of such a carpet, abutments can be made to pipes, walls, etc. One half of it is glued to the wall or pipe, the other to the coating. The upper edge of the carpet is pressed by a metal bar, which has a curved profile, which ensures reliable waterproofing of the structure. The connection between the strip and the wall is sealed with a sealant to prevent leakage.
The junction block can also be performed without a carpet. In the angle formed by the abutment, mount the angled bar (apron), which is covered with a second apron – fixed in the stunt on the adjacent surface. And the design of two aprons and special wooden bars makes it possible to create even a ventilated abutment.
