Rafter

A rafter is a parallel beam used as a structural component of a roof. Integral parts of a roof structure in both residential construction and commercial buildings, rafters serve as the backbone supporting the roof and providing its overall shape. 

Example: Rafters support the roof’s weight, along with the weight of any snow or rain that may accumulate. Maintaining the roof and the rafters beneath it is crucial to protecting your home or business from leaks, damage, or a complete collapse.
