Roof overhang: preparation, material selection and process

To make the roof complete, you need tonot only to assemble the roofing materials, but also to make a filing of its hanging parts (eaves). Preparatory work for this begin at the stage of installation of rafters: the ends of the rafters need to be sawed in one line. Pay attention not only to the length of the outstanding section of the rafters, but also to the angle of the saw: it must be parallel to the wall.

The next step, which requires filing overhangsroofs, this is a crate installation. She uses boards for her. They are mounted parallel to each other. The general appearance of the roof depends on how carefully the preparatory works are performed. To make the joint between the facade and the roof sealed, the filing of overhangs of roofs is done before the installation of the heater. This guarantees better sealing, which means a longer service life of the materials.

Selection of materials for filing

When arranging the file, do not forget aboutventilation: the material must be protected from ingress of atmospheric precipitation, but it must necessarily have surplus moisture output channels, otherwise accumulating condensate will cause destruction of roofing materials.

Most often the filing of overhangs of roofs is performed fromprofiled, lining (wooden or PVC) and soffit. Profiled sheeting is advisable to use if the roofing material is used for roof tiles or the corrugated board itself. This material has good strength and guarantees high-quality protection against precipitation.

Sofit - a kind of plastic panels,designed specifically for filing roofs. It has a large thickness in comparison with siding and a special perforation, which is necessary for ventilation. Soffit is mounted perpendicular to the plane of the roof. Other options are not provided for by technology.

It is a popular filing of roof overhangs by lining. When using a wooden lining, it should be chosen carefully: the wood should not have too low humidity, and the lining must be sufficiently thick (not less than 5-7 mm). PVC lining is the most economical option. Choose waterproof types and do not forget about the plastic corners, which are necessary for the processing of joints.

The order of filing overhangs

To the pre-sawn rafters from below and from the endsfill the guides (boards). Also, a board is fixed on the wall, to which the end of the binding strips will be fastened. If the roof protrudes beyond the wall by more than 40 cm, another intermediate guide is needed, otherwise there will be sagging of the slats, and also possible damage to the filing under strong wind.

Fixing overhangs of roofs from the lining is mounted tothese slats. Using a soffit, a special bar is fixed and fixed with screws. Soffit sheets are cut into strips of the necessary width (it is equal to the distance between the mounting plates minus 6 mm for thermal expansion). Profiled sheeting with screws to wooden slats. To ensure ventilation, its width should be slightly (1-2 cm) shorter than the width of the overhang. All works require accuracy, but there should not be any difficulties in observing the recommendations. You can, of course, entrust all professionals, but filing roof overhangs (the price is counted as a square, also added usually for high-rise works) is quite expensive.
