A soffit and an overhang serve different architectural purposes. A soffit is the underside of a roof's eave, often ventilated, covering the space between the roof edge and the exterior wall. It helps with attic ventilation and aesthetics. An overhang is the extension of the roof beyond the exterior wall, providing protection from the elements and helping to keep walls dry. While the soffit often exists within an overhang, they perform distinct roles.**
