Which board encloses the ends of rafter projections typically referred to as tails?

The fascia board is the component that encloses the ends of rafter projections, which are often referred to as tails. It serves both a functional and aesthetic purpose by providing a finished edge to the roofline and supporting the lower edge of the roof, often serving as a mounting point for gutters. The fascia is typically installed at the eaves and can be easily distinguished as it runs horizontally along the roof, directly behind the gutters.

In contrast, soffit refers to the material that covers the underside of the roof overhang, functioning to ventilate the attic space and improve air circulation. Gables are the triangular sections formed by the sloping sides of a roof, typically found at the ends of a building, and they do not directly interact with rafter tails. Eaves describe the lower edges of a roof that overhang the walls of a building, which can be an area where both fascia and soffit are installed, but the term does not specifically refer to the board that encloses rafter projections. Hence, the fascia is specifically tasked with enclosing the ends of the rafter tails.
