What Is Soffit?
The soffit is the material that covers the underside of your roof's overhang the section that spans from the wall of your home to the outer edge of the roofline. Properly ventilated soffits allow airflow into your attic, helping regulate temperature and prevent moisture buildup that can lead to mold, rot, and structural damage. Vented soffit is particularly important for attic health in climates with extreme temperature swings.
