Purpose Of A Roof Truss

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.

Purpose of a roof truss.

A roof truss is considered the most important key component in engineering system in a building. Consequently engineers developed the truss. Trusses usually occur at regular intervals linked by longitudinal timbers such as purlins. Without roof buildings would be exposed to all kinds of elements rendering them completely useless.

For larger spans and thinner walls this can topple the walls. Trusses are web shaped structures used to bear tremendous weight. They serve a critical function and design depends on various factors. The space between each truss is known as a bay.

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. They bridge the space above rooms and occur at regular intervals held by longitudinal posts for support. Used in buildings and bridges of all sizes trusses allow builders to extend the dimensions of structures and create interesting shapes. Man with a drill.

Basically they are triangular wooden structures designed to keep the integrity of a roof. Roof trusses which are structural components of houses or commercial buildings support the weight of roof timbers and coverings. A truss roof is a triangular wooden structure constructed in mass quantities at a factory and shipped to job sites. Tremendous pressure was placed on materials that were unable to bear significant weight.

This truss requires a soffit siding and additional insulation work from the onset which elevates construction costs. 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. Pairs of opposing rafters were thus initially tied together by a horizontal tie. These trusses should never be removed or altered without the advice of a structural engineer.

Their mass production and availability have made them much more common than conventional roofs in today s construction industry. Here are some of the benefits of installing a roof truss.
