What are rake or barge boards?

Rake or barge boards are specifically the boards placed at the ends of the rafters. Their primary function is to provide a finished look to the roofline while also serving a practical purpose. They help protect the rafter ends from exposure to the elements, preventing water damage and deterioration. Additionally, these boards can add decorative detail to the roof's appearance, enhancing the overall aesthetics of a structure.

Support structures at the ridge refer to different components that help maintain the roof's integrity but do not relate specifically to rake or barge boards. Roof shingles are the materials that cover the roof itself, providing waterproofing and protection, but are not related to the framing or finishing of the rafter ends. Managing drainage typically concerns components like gutters and downspouts, and while they are essential for proper water management, they do not pertain to the function or definition of rake or barge boards.
