A roof rafter is a crucial component in a building's roof structure. It's essentially a beam that runs from the peak of the roof down to the walls. Rafters provide the necessary support for the roof covering and sheathing, helping to bear the load of the roof and any external forces such as snow or wind. Constructed from wood or metal, rafters are part of the framework that shapes the roof and ensures its stability and durability.
