Trussed Roof With Non 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.
Trussed roof with non load bearing walls. Most simple construction truss roof home s roof and trusses are supported by the exterior walls perpendicular to the trusses. Actually a quick way to determine if the wall is bearing is to cut hole at the top to see if it has one or two top plates. An example of a non load bearing partition wall can be seen on the left. Best answer so far.
When joists trusses are perpendicular to the wall and bear o n the top of the wall that wall is bearing wall. Roof trusses support a roof s weight by transferring the weight load downward and outward to the building s bearing walls. One top plate and a space between the bottom chord of the truss and the top of the wall non load bearing. But do consider ussuri s point about the overall lateral stability of what will remain and mikethe engineer s point about proper anchorage of the roof trusses to the bearing walls.
If the wall in question is parallel to the joists trusses it will likely not be load bearing. 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. Internal wall brackets are used to connect internal non loadbearing walls to roof trusses at maximum 1800mm centres. Chances are this is a non bearing.
Regardless the wall beneath it is likely not load bearing. If you have the drywall all removed now would be the ideal time to upgrade the wind load path from roof truss to foundation. They do this by means of top chords which are sloping members that extend from the peak of the roof to the top of the exterior walls at the eaves.
