How many bearing points do roof trusses typically rest on when installed by the framing crew?

Roof trusses are engineered structural components specifically designed to support the roof of a building. When installed, they typically rest on two bearing points, which are usually located at the exterior walls of the structure. This design ensures proper load distribution and stability, as the two bearing points provide a secure foundation for the truss system to transfer the weight of the roof to the walls below.

Having two bearing points allows for efficient material use and helps maintain the overall structural integrity of the building. Additionally, this setup simplifies the framing process and minimizes potential points of failure while ensuring that the roof can effectively carry its load, including snow, rain, and other environmental factors.

Although roof trusses can be designed to rest on more than two points depending on the building's design or specific engineering requirements, the standard installation in most residential constructions typically involves two bearing points.
