Sloping roof beams, also known as RAFTERS, are structural members used to support the roof of a building. They are typically made from wood and run from the ridge board or hip board to the wall plate or eaves. RAFTERS are usually placed at regular intervals and are connected to each other by purlins, which help to distribute the load of the roof. Sloping roof beams provide strength and stability to the roof structure, and are an essential part of any building.
