The fascia board is one of the most important parts of the roof. This is the board that is along the bottom of the ends of the rafters at the eaves that closes the gaps between the rafters. Fascia boards are visible and usually are what holds gutters in place. Most fascia boards are wood but can also be made out of PVC plastic, aluminum, or vinyl. In recent years, PVC has become the preferred choice because it is long-lasting and requires little maintenance. Sometimes the fascia will support the bottom row of tiles and/or slates.

Fascia boards are meant to protect the roof and interior upper floors of a house from water and moisture by blocking off the space between top of the house and the roof. Fascias also serve aesthetic purposes-they help create a smooth and even roof edge. They are susceptible to damage from water and moisture if a leak causes water to pool or run down into the boards of the roof. Water damaged fascias are most often caused by clogged gutters, ice dams, and improperly installed shingles.

Since the fascia is is a vital part of protecting the roof, it also needs to be protected as well. They way to do this is by installing a drip edge-material installed on the edge of a roof that allows water to flow out of the roof system helping prevent damage. Drip edges are usually made out of copper, aluminum, galvanized steel, or other combinations of metals. These metals are non-staining and will not erode. Drip edges are not required but are recommended, especially in areas experiencing frequent rain.

It is recommended to regularly inspect your fascia for damage including cracks, splits, and discoloration. If the fascia has been exposed to water, rot can occur and it will detach from the house making your home vulnerable to leaks.
