To give the roof a complete look, it is necessary not only to mount roofing materials, but also to file its hanging parts (overhangs). Preparatory work for this begins even at the stage of installing the rafters: the ends of the rafters must be sawn in one line. Pay attention not only to the length of the protruding section of the rafters, but also to the angle of the cut: it should be parallel to the wall.
The next step, which requires filing the roof overhangs, is the installation of the batten. Boards are used for it. They are mounted parallel to each other. The overall appearance of the roof depends on how carefully the preparatory work is done. To make the joint between the facade and the roof airtight, filing the roof overhangs is done before the installation of the insulation. This guarantees a better seal, which means a longer life of the materials.
Selecting materials for filing
When arranging the filing, one should not forget about ventilation: the material must be protected from atmospheric precipitation, but it must have channels for removing excess moisture, otherwise the accumulated condensate will cause the destruction of roofing materials.
More oftenin total, the filing of roof overhangs is made of corrugated board, lining (wooden or PVC) and soffit. It is advisable to use corrugated board if tiles or corrugated board itself are taken as roofing material. This material has good durability and guarantees high-quality protection against atmospheric precipitation.
Soffit is a type of plastic panels designed specifically for roof lining. It has a greater thickness compared to siding and special perforation, which is necessary for ventilation. The soffit is mounted perpendicular to the plane of the roof. Other options are not provided by technology.
Filing of roof overhangs with clapboard is popular. When using a wooden lining, it must be chosen carefully: the wood should not have too low humidity, and the lining must also be thick enough (at least 5-7 mm). PVC lining is the most economical option. Choose water-resistant types and don't forget about plastic corners, which are necessary for processing joints.
The order of filing overhangs
Guides (boards) are stuffed to pre-sawn rafters from the bottom and from the ends. A board is also fixed on the wall, to which the end of the filing planks will be attached. If the roof protrudes more than 40 cm from the wall, another intermediate guide is needed, otherwise sagging of the planks will be observed, and the lining may also be damaged in strong winds.
Filing of roof overhangs from lining is mounted to these slats. With the help of a soffitattach a special bar, which is fixed with screws. Soffit sheets are cut into strips of the required width (it is equal to the distance between the mounting strips minus 6 mm for thermal expansion). Decking is fastened with screws to wooden planks. To ensure ventilation, its width should be slightly (1-2 cm) shorter than the width of the overhang. All work requires accuracy, but there should be no difficulties in following the recommendations. You can, of course, entrust everything to professionals, but filing roof overhangs (the price is considered per square, besides, they usually add it for high- altitude work) is quite expensive.
