A rafter is a structural beam that supports the roof of a building. Typically made from wood, metal, or engineered materials, rafters are positioned at an angle from the ridge or peak of the roof down to the eaves. They help bear the weight of the roof covering, such as shingles or tiles, and distribute the load evenly to the walls of the building. Rafters are essential in creating the roof's shape and design, providing stability and strength while allowing for insulation and ventilation. Proper installation of rafters is crucial for ensuring the overall integrity and durability of the roof structure.
