What is a hip rafter?

A hip rafter is defined as a rafter that forms the intersection of an external roof angle. It is typically located at the corners of a roof structure and helps to create a sloped roofing surface that directs water runoff away from the building. The hip rafter plays a crucial role in supporting the overall roof framework and providing stability to the roof's design.

In roofing, hip rafters are essential in designs such as hipped roofs, where all sides slope downward toward the walls, and they meet at the ridge line. This design not only adds aesthetic appeal but also enhances structural integrity.

Understanding the function of a hip rafter is vital for proper roofing installation and can help ensure adequate drainage and long-term performance of the roof.
