A roof soffit is the surface beneath the overhanging section of a roof eave. It plays a crucial role in ventilating the attic, preventing moisture and heat buildup which can lead to rot and decay. Soffits also enhance a building's aesthetics and protect rafters from weather elements. Incorporating soffit vents can significantly improve attic ventilation, contributing to a more energy-efficient and durable home.
