Purpose of a roof truss.

At the site the truss roof frames are put together by framing carpenters. These trusses should never be removed or altered without the advice of a structural engineer. For larger spans and thinner walls this can topple the walls. A structural framework designed to provide support and strength to a roof a truss is essential as the roof s frame.

Trusses are web shaped structures used to bear tremendous weight. A roof truss is considered the most important key component in engineering system in a building. Consequently engineers developed the truss. This truss requires a soffit siding and additional insulation work from the onset which elevates construction costs.

Without roof buildings would be exposed to all kinds of elements rendering them completely useless. A timber roof truss is a structural framework of timbers designed to bridge the space above a room and to provide support for a roof. A truss roof is a triangular wooden structure constructed in mass quantities at a factory and shipped to job sites. Trusses usually occur at regular intervals linked by longitudinal timbers such as purlins.

The space between each truss is known as a bay. Pairs of opposing rafters were thus initially tied together by a horizontal tie. They bridge the space above rooms and occur at regular intervals held by longitudinal posts for support. Rafters have a tendency to flatten under gravity thrusting outwards on the walls.

Used in buildings and bridges of all sizes trusses allow builders to extend the dimensions of structures and create interesting shapes. They serve a critical function and design depends on various factors. Basically they are triangular wooden structures designed to keep the integrity of a roof. Man with a drill.

The raised heel roof truss reduces condensation problems since the truss creates a vapor barrier and is commonly seen in humid climates where mold is a common issue. Here are some of the benefits of installing a roof truss.
