What is a roof truss?

A roof truss is an engineered frame that supports a roof and transfers its loads to bearings. Metal-plate-connected wood trusses use lumber chords and webs arranged in triangles.

What are the parts of a roof truss?

The top chord, bottom chord and webs form the truss frame. SBCA describes the bottom chord as working with the other members to transfer forces to the bearings. “In addition to the top chord and webs, the bottom chord is used to transfer forces to the truss bearings.” Source: Structural Building Components Association, read 2026-10-31.

How does SBCA define a roof truss?

SBCA describes metal-plate-connected wood roof trusses as an engineered assembly of lumber. The connected members form a supporting framework beneath the roof covering. “Roof trusses are highly engineered pieces of lumber connected by metal plates to form a web that supports a roof structure.” Source: Structural Building Components Association, read 2026-10-31.

How do roof trusses work?

Trusses use connected triangles to carry forces through their members to the bearings. SBCA explains that this action involves both compression and tension in roof and floor trusses. “In roof and floor trusses, wooden triangles are used to pass compression and tension forces throughout the structure to its bearings.” Source: Structural Building Components Association, read 2026-10-31.

What are roof trusses made of?

The wood trusses described by SBCA combine lumber members with metal connector plates. Member sizes vary: its bottom-chord discussion lists 2x4 and 2x6 lumber as well as larger sizes and LVL. “For traditionally spaced trusses, the bottom chord is cut out of 2x4 or 2x6 dimension lumber but can also be cut out of 2x8, 2x10, 2x12, and even LVL material for roof trusses.” Source: Structural Building Components Association, read 2026-10-31.

What is a raised heel roof truss?

A raised heel roof truss has extra depth where it crosses the exterior wall. DOE explains that this provides room for insulation over the wall’s top plate. “Oversized or raised heel energy trusses extend further past the wall and are deeper at the wall, allowing room for full insulation coverage over the top plate of the exterior walls.” Source: U.S. Department of Energy, read 2026-10-31.

Do roof trusses need bracing?

Yes. SBCA calls for temporary and permanent bracing. Its continuous lateral restraint, or CLR, discussion explains how restraint helps prevent web members from deforming or buckling. “Temporary and permanent bracing are both required during and after installation.” Source: Structural Building Components Association, read 2026-10-31. “The purpose of a CLR is to prevent deformation and/or buckling of the web member and the series of truss members to which it is attached.” Source: Structural Building Components Association, read 2026-10-31.
