Engineered Roof Trusses Load Bearing Walls

We usually build on the exterior walls set the trusses and do all of the chord blocking and truss bracing before buildin.

Engineered roof trusses load bearing walls.

Factors that affect truss pricing and cost. The span in short is the length of the bottom of the truss. No expert but a traditionally constructed roof needs some type of support in the form of a beam or load bearing wall in the house. Photograph the trusses draw them to scale take the pictures and elevation plan of the trusses to a reseller lumberyard and ask would a new truss like that be a clear span design if yes you can remove the wall use floating slotted clips between the top plate and truss bottom cord to reduce drywall cracking.

Roof trusses support a roof s weight by transferring the weight load downward and outward to the building s bearing walls. Most simple construction truss roof home s roof and trusses are supported by the exterior walls perpendicular to the trusses. For example a gable end truss may be designed with support members that transmit the roof weight load outward to the side walls allowing the end wall directly below it to have breaks or openings in it that would otherwise be impossible. Support for a roof built with engineered trusses comes from the sides of the house and is distributed that way so you wouldn t need a load bearing wall in the house.

This is the distance of the bottom chord of the truss from outside overhang of bearing wall to outside of the other bearing wall. Load bearing walls support the weight of a floor or roof structure above and are so named because they bear a load. Some spans have a lower rate per foot than others. Engineered roof truss systems may be designed to eliminate the need for load bearing walls or change where the bearing walls are located.
