How to install a cornice strip?

When completing the final roofing work, do not forget about such details as gutters, curtain rods and slats. Since a high-quality result (a strong, non-leaking roof) largely depends on these small, but such important elements. Consider how to install a curtain rail.

Cornice strip

The cornice strip (overhang) is classified as additional elements of the roof, while it performs both a decorative function and a protective role. This part preserves the lower level of the crate and the frontal wooden elements from the effects of precipitation. It also protects the roofing sheets from all kinds of deformations. The bar for the cornice is made of metal and plastic in various shades, which is important when selecting the mentioned building material for the roof lining and the drainage system.

How can I fix the cornice strip?

1. Due to the formation of the protrusion of the transverse beam (tightening). At the same time, special devices (scarves, nozzles) are provided to strengthen the fastening of rafters with bearing surfaces. In this case, the roof structure will resemble the shape of a mushroom, and such a system is usually provided for in the construction of buildings made of wood and frame-panel devices.

2. Due to the departure of the rafter elements beyond the external level of the wall. In order to protect against blowing out the space under the roof, brick eaves are installed under the overhang to the upper level of the trusses. Such a device is used in brick and stone structures with reinforced concrete floors.

Mounting the eaves overhang

The cornice strip is installed so that it directs the flowing water along 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 design should be at least 0.5 m. When organizing drainage through storm drains, this value can be reduced.
  • Installation of the cornice strip should be carried out in such a way that there are no gaps, holes, etc., since otherwise the attic will be blown out. And this, in turn, can lead to significant heat loss in the house.
  • The overhang must be installed before the fastening of the roofing sheets is made, while the bar must be attached tightly, without gaps. Only in this case, noise from gusts of wind will not be heard.
  • The elements of the cornice should be fixed with an overlap along the length (range 5–10 cm).
  • The bar is attached to the frontal board and the cornice with the help of galvanized nails or self-tapping screws, while the fastening step should not exceed 30 cm.
  • The edges of the cornice waterproofing layer must be laid on top of the lower level of the crate and overhang.
