The fascia is a portion of the frieze or the band that runs horizontally under a roof edge or forms on the outer surface of a cornice. It typically is made of fiber-cement or a wooden board. The term also can be used to describe a wide and flat trim strip around a doorway. It often is used in order to hold the rain gutter in place and to prevent moisture damage. The fascia acts as an edge of the roof and the outdoors and it works to protect the wooden board or sheet metal against any water damage.
While a fascia typically plays a functional role, it also can be an important aesthetic role because it creates a smooth and even appearance on the edge of a roof. While it protect from water damage, it also protects the entire roof and the interior of a home or business from weather damage by blocking its entrance. Most modern homes have a fascia, while older homes lack this helpful component.
A professional home inspector can inspect the area and determine if any rot or damage exists that a professional contractor can remain. Exposing a home to damaging weather conditions is irresponsible and can cost you as a homeowner countless dollars of repair.
