Roof Interior Structure

The rafters and trusses are connected to the ridge board for a cohesive framework.

Roof interior structure.

This house uses trusses for the roof framing. 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 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. Trusses are quite common these days because they have five big advantages from the builder s standpoint.

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. It resembles real wood and particularly strong and stable for bearing heavy load. The rafters do the heavy lifting for a roof structure. A simple stick built triangular roof structure has three main components.

Next are the rafters which are fastened to the ridge board and slope downward to the exterior walls. Trusses are pre fabricated triangulated wooden structures used to support the roof. A horizontal timber or metal resting at the peak of the roof. A composite decking made of solid materials.

A roof is an integral part of a building and people try to personalise the roof designs to achieve optimum architectural splendour. The alternative is to build up the roof s frame with 2x8s and 2x10s.
