Composition, purpose and device of roof ventilation
The roofing structure includes not only a variety of coatings, like flexible, composite, ceramic, metal tiles, but also a set of additional materials and elements. This is the waterproofing of the roof, insulation, ventilation elements and much more.
After all, all the elements and systems of roof ventilation carry and perform their tasks and functions. Ventilation of the sub -seal space and ensuring the location of all layers of the roof according to the technological rules and norms, protect the roof from negative phenomena, preserve heat in winter, and in the summer cool.
For example, with an attic roof, it will require its compulsory insulation. The vapor barrier layer will protect the insulation from wet vapors emanating from the room. And in turn, from the outside, it will be protected by waterproofing. In the roofing structure, the formation of condensate will precisely prevent ventilation. Therefore, the wooden parts of the roof will be protected from decay. Wet air is removed from under the roof using ventilation. Air passes through the ventilation duct, which forms the counter.
Through the groove or a hem of the cornice, it is necessary to provide an air flow, and to exit it, use the upper point of the roof and equipped with aerators – ventilation elements. Experienced builders recommend not saving on the constituent structures of the entire roof and ventilation system in order to ensure the reliability of the operational properties of the roof for a long time.
