The answer to 'which is better soffit or' is that both soffits and vents serve important functions for a home's roofing system, but the better choice depends on the specific needs and conditions of the home. Soffits are the horizontal boards that run along the underside of a roof's overhang, while vents are openings that allow air to circulate in the attic space.
Soffits provide important ventilation and prevent moisture buildup in the attic, which can lead to mold, mildew, and other structural issues. Vents, on the other hand, help remove hot air from the attic and improve energy efficiency. In many cases, a combination of soffits and vents is the best solution for optimal attic ventilation.
