What is the term for the horizontal board enclosing the ends of the rafter projections?

The term for the horizontal board that encloses the ends of the rafter projections is called fascia. This component is usually installed at the edge of the roof and serves several important functions. It not only provides a finished appearance by covering the ends of the rafters, but it also plays a critical role in protecting the rafters from moisture and pests. Additionally, fascia boards commonly serve as a mounting surface for gutter systems, helping to direct water runoff away from the roof and prevent damage to the underlying structures.

In contrast, soffit refers to the material used to close the underside of the roof overhang, which helps ventilate the attic and prevent moisture buildup. The term rake typically describes the angled edge along the roof's pitch at the gable end, while a frieze is a decorative horizontal band that might be found under the roof eaves or same plane as the soffit but does not serve the functional role of enclosing rafter ends like fascia does. Understanding the correct terminology helps in identifying and communicating about roofing structures effectively.
