Purpose Of A Roof Truss

These trusses should never be removed or altered without the advice of a structural engineer.

Purpose of a roof truss.

Here are some of the benefits of installing a roof truss. Basically they are triangular wooden structures designed to keep the integrity of a roof. At the site the truss roof frames are put together by framing carpenters. A truss roof is a triangular wooden structure constructed in mass quantities at a factory and shipped to job sites.

They serve a critical function and design depends on various factors. Roof trusses which are structural components of houses or commercial buildings support the weight of roof timbers and coverings. 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. Usually they are constructed from pieces of timber or steel which are nailed bolted or pegged together to form a mutually supporting and strong base for a roof.

For larger spans and thinner walls this can topple the walls. Man with a drill. They bridge the space above rooms and occur at regular intervals held by longitudinal posts for support. Without roof buildings would be exposed to all kinds of elements rendering them completely useless.

Trusses are web shaped structures used to bear tremendous weight. Trusses usually occur at regular intervals linked by longitudinal timbers such as purlins. A roof truss is considered the most important key component in engineering system in a building. Rafters have a tendency to flatten under gravity thrusting outwards on the walls.

Their mass production and availability have made them much more common than conventional roofs in today s construction industry. 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. Consequently engineers developed the truss. This truss requires a soffit siding and additional insulation work from the onset which elevates construction costs.

Tremendous pressure was placed on materials that were unable to bear significant weight. The space between each truss is known as a bay.
