Roof interior structure.

A roof is much more than just the decorative top of a building. A composite decking made of solid materials. A roof provides protection from the elements and precipitation helps drain water away from a structure and provides insulation that helps keep the interior of a building warm or cool depending on the season. Trusses are pre fabricated triangulated wooden structures used to support the roof.

A roof is an integral part of a building and people try to personalise the roof designs to achieve optimum architectural splendour. A horizontal timber or metal resting at the peak of the roof. Next are the rafters which are fastened to the ridge board and slope downward to the exterior walls. Trusses are quite common these days because they have five big advantages from the builder s standpoint.

First there s a ridge board which is a horizontal wood element at the peak of the roof establishing the apex of the roof s triangle. The alternative is to build up the roof s frame with 2x8s and 2x10s. It resembles real wood and particularly strong and stable for bearing heavy load. The most effective vents have four open sides and rise above the roof which allows them to capture the wind from all directions to produce a suction effect.

Roof vents these enclosed structures made of metal or plastic feature openings and fins ensuring that the attic space is properly ventilated. The rafters do the heavy lifting for a roof structure.
