Soffit is the exposed surface beneath the overhanging section of a roof eave. It can also refer to the horizontal underside of similar architectural structures such as an archway, staircase or ceiling. The function of soffit is to assist in ventilating the attic in your home, which helps draw heat and moisture away. Fascia is a vertical finishing edge connected to the ends of the rafters, trusses, or the area where the gutter is attached to the roof. Contact a representative today about the options available.
