The fascia is the long board that runs along the roof’s lower edge. It’s situated at the bottom of the trusses or rafters, and while decorative, it plays a vital role, giving you a place to attach your gutters.
Rain gutters are a water drainage system attached to your roof’s fascia board. Most gutters are aluminum and look like long, hollow pieces. The purpose of a rain gutter is to direct rain and snow run-off away from your home’s foundation.
