Soffit is typically installed under the eaves of a home’s roof, as well as under the ceilings of porches, decks, overhangs, and arches. Aesthetically, soffit helps a home look more finished by covering exposed eaves or ceiling beams with vinyl material that coordinates with your home’s exterior cladding.

More importantly, soffit siding helps ensure proper ventilation by allowing moisture to escape from your home’s exterior surfaces.
