The term 'roof supporter' refers to the structural components of a roof that provide support and stability. The two most common roof supporters are rafters and beams. Rafters are typically long, sloping pieces of wood or metal that form the shape of the roof and provide support for the roofing material. Beams are usually thicker and more rigid than rafters and provide additional support for the roof. Together, rafters and beams form the framework of a roof and ensure its structural integrity.
