Fasciais the vertical board that runs along the lower edge of your roof, capping the ends of the rafters. It's the “face” of your roofline — the board your gutters attach to. Fascia provides structural support for the bottom row of roof tiles or shingles and creates a finished appearance at the roof edge. When fascia fails, gutters pull away, water runs behind the wall, and the entire roof edge becomes vulnerable.
Soffit is the horizontal panel that covers the underside of your roof overhang (the area between the fascia and your exterior wall). Soffit panels serve two critical functions: they seal the attic space from pests, weather, and debris, and they provide essential ventilation through perforated or vented panels that allow air circulation through the attic. Without proper soffit ventilation, your attic traps heat and moisture that shorten roof life and drive up cooling costs.
Together, soffit and fascia form the protective perimeter of your roof system. In South Florida, where hurricanes test every edge, salt air corrodes every surface, and humidity rots every piece of exposed wood, maintaining these components is not cosmetic — it's structural.
