Soffit is the finished surface underneath a roof overhang. On many homes, soffit panels include ventilation openings that help bring fresh air into the attic.

Why It Matters

Soffit affects both appearance and performance. Vented soffit can support attic airflow, while solid or blocked soffit can limit intake ventilation.

Common Problems

Common issues include blocked vents, loose panels, animal damage, water staining, poor ventilation, and soffit that does not coordinate with the attic ventilation design.
