Soffit
The horizontal underside of a roof overhang, typically ventilated to allow airflow into the attic space.
Why It Matters for Homeowners
Why it matters: a roof system depends on airflow, and vented soffits are half of that system. Without them, hot air gets trapped in the attic, bakes the underside of the shingles, and shortens roof life by years. Most shingle manufacturer warranties actually require continuous intake-and-exhaust ventilation, which means soffit ventilation is not optional, it is tied to keeping the warranty valid.
