The final stage in the construction of a private house is the installation of the roof. In order for it to be pleasing to the eye, and all the roof rafters are neatly hidden and protected, you need to hem the roof cornice.
In addition to the aesthetic component, the hemming of overhangs has a number of important functional features:
If the overhang is properly hemmed, then given the peculiarities of air circulation under the roof, you do not have to worry about excess debris or moisture that can get under the roof and damage the insulation or other building elements.
In construction, there are two types of overhangs:
There are many material options for sheathing the overhang of the roof, here everyone is guided by their material capabilities and the style of the house as a whole. All filing materials can be divided into three large groups.
For filing a wooden house, for example, an edged or hemmed board is suitable. A coniferous board is best suited, the width of which will be 50-250 mm, thickness 170-220 mm. It is imperative to let the board lie under the roof for about a month before installation - so it will not be too dry or too wet. And don't forget to treat it with antiseptic, varnish or paint. During installation, it is important to leave 10-15 mm gaps between the boards, they will ensure proper air circulation.
Another option is a wooden lining . Many people choose this particular material, because it does not require any additional preparation, like a regular board. The only thing is that the lining also needs to lie in the open air for a month. During installation, there is no need to leave gaps for ventilation - special ventilation grilles are installed.
Siding is by far the most popular facing material.
Cornice siding is called soffit.It differs from the usual one in that the soffit has ventilation grilles, while the installation process is identical.
Soffits, in turn, are divided into several types depending on the material:
The disadvantage is that it is slightly cheaper than copper, but not significantly.
Profiled sheeting during installation and looks very similar to soffits, even the material is the same - galvanized metal. Only for corrugated board the dimensions are much larger and ventilation grids are not provided, it is important to take this into account during installation, since you will have to add them yourself.
! Important. The filing of overhangs must be done prior to finishing the exterior walls of the house.
Roofers use two overhang filing options:
For installation, all the lower parts of the rafters must be in the same plane. If you can't cut it straight, you need to fill up an additional flat board. The first step is to expose and screw on the first and last trims. Next, you need to pull the rope between them for balance, after which you can fasten the remaining planks. For cladding, metal corners and screws are used.
! Important. Use screws and corners as fastening materials, not nails, this will give the frame good rigidity.
If you plan to sheathe the eaves of the roof yourself, we recommend that you use vinyl soffits and suggest the following algorithm of actions:
! Important. PVC soffits must be installed when the air temperature is above 15 ° C, in the cold the material is easily damaged.
