How to fix the horse on the roof
The construction of any building involves the construction of the roof, in the construction of which there is an important element - the roofing ridge. Its installation completes all construction. The ridge is located at the highest point of the building and is a horizontal edge formed at the junction of roof slopes. This element prevents the ingress of atmospheric precipitation and provides the necessary ventilation of the space under the roof. How to fix the horse will be described in this article.
Such a construct is a component of gable and more complex types of roofing. The ridge is present, for example, on broken roofs that have four slopes. The roof may have an irregular shape with several slopes and offset skates.
Varieties
Ridge strips used in roofing can be of several varieties, depending on their shape and material. The modern construction market offers a wide variety of such structural elements.
The ridge set can be selected or manufactured for any roof covering:
- galvanized and / or painted steel;
- ceramic composition;
- bituminous material;
- asbestos-cement products;
- plastic.
Usually the ridge profile is selected from the same material as the roof itself. The roof, in this case, looks harmonious and aesthetic. Forms of the skate can be very different, it depends on the architectural style of the building.
Installation Features
When installing the coating, a sufficient distance between the layers of the roofing “pie” is always left to ensure free air access. The installation of a ridge aerator system equipped with a protecting insect screen will be technologically justified.
For the roof of slate or ceramic tiles is determined by the installation height of the roofing ridge. An additional third support is mounted under it, significantly extending the service life of this part of the structure. Its height is equal to the measured distance from the junction of the rafters to the inside of the ridge bar. In accordance with the measurements obtained, a board is cut that is equal to this width and is attached to the roof rafters.
Installation
The ridge profile is installed after the completion of the roofing installation in this order.
- At the upper junction of the slopes, a special support bar is installed with a cross section of 70 × 90 mm. After its fixation to the rafter pairs, two sheathing beams are attached to them on both sides. It is possible to facilitate the process by attaching special brackets to the support beam and hanging on them running bridges intended for these purposes.
- A well-fixed support bar, the upper face of which is rounded to fit more closely and treated with special protective compounds, is mounted a ridge board.
- For roofing sheeting or metal, ridge elements are mounted directly on the support beam. As a fastener, it is better to use screws with waterproofing gasket. The overlapping of ridge profiles laid on adjacent ramps is done with their overlap (see fig.). The ridge, if provided for by the design, is laid over the auxiliary parts and the aerator system.
The installation of the ridge elements is not technologically complicated, but requires great care when performing. Installation must be performed in exact sequence, following all practical recommendations of specialists. The horse is the most important detail of the roof. Qualitatively assembled, it will ensure the correct functionality of the design not only of the coating, but also of the entire building.
