When performing final roofing work, do not forget about such details as gutters, cornice overhangs and slats. Since the qualitative result (a strong, non-leaking roof) largely depends on these small, but such important elements. Let's see how to install the curtain rod.
Cornice plank
The cornice strip (overhang) is classified as an additional roofing element, while it performs both a decorative function and a protective role. This detail saves the lower level of the crate and frontal wooden elements from the effects of precipitation. It also protects the roofing sheets from all kinds of deformations. The strip for the cornice is made from metal and plastic of various shades, which is important when selecting the mentioned building material for the roofing and drainage system.
How can I fix the curtain rod?
1. Due to the formation of a protrusion of the transverse beam (puff). At the same time, to strengthen the fastening of rafters withbearing surfaces provide special devices (kerchiefs, nozzles). In this case, the roof structure will resemble the shape of a mushroom, and such a system is usually provided for the construction of buildings made of wood and frame-panel devices.
2. Due to the departure of the truss elements beyond the outer level of the wall. At the same time, to protect against blowing the space under the roof under the overhang, brick cornices are installed to the upper level of the trusses. Such a device is used in brick and stone structures with reinforced concrete floors.
Installation of the overhang of the eaves
The cornice strip is installed in such a way that it directs the flowing water through the gutters into the drain. When carrying out installation work, it would be nice to take note of the following points:
- The overhang of the roof, or the removal of this structure must be at least 0.5 m. When organizing drainage through storm drains, this value can be reduced.
- Installation of the cornice strip should be done in such a way that there are no slots, holes, etc., otherwise the attic space will be blown through. And this, in turn, can lead to significant heat loss in the house.
- The overhang must be installed before the roofing sheets are fixed, while the plank must be attached tightly, without gaps. Only in this case, the noise from gusts of wind will not be heard.
- Eaves elements should be overlapped in length (range 5-10 cm).
- The bar is attached tofrontal board and cornice using galvanized nails or self-tapping screws, while the fastening step should not exceed 30 cm.
- The edges of the eaves waterproofing layer must be laid over the lower level of the batten and overhang.
This device allows you to protect the inner layers of the roof from moisture and wind. The considered additional element is distinguished by a variety of forms, it all depends on the roofing. Recently, the cornice strip for metal tiles has been very popular, since it is this material that is most often used to decorate the roof. And it will not be difficult for you to pick up the mentioned detail for the designed roof structure.
