Soffit and fascia are the finishing edge of your roof, and they do far more than look tidy. The fascia is the vertical board that runs along the ends of your rafters where the roof meets the wall. It closes off the roof edge, supports the bottom row of shingles, and provides the mounting surface for your gutters. Every gutter on your home hangs from the fascia, so when that board weakens, your entire drainage system is at risk.
The soffit is the horizontal underside panel that tucks beneath the roof overhang, bridging the fascia and the exterior wall. Beyond hiding the rafter tails, the soffit carries the vents that let your attic breathe. Fresh air enters through soffit vents at the eaves and exits near the ridge, creating the airflow that keeps your attic dry and your roof deck healthy. When soffit and fascia work together, they seal the roof edge against weather and pests while quietly ventilating the whole system above them.
