Attic ventilation is the process of allowing air to flow in and out of the attic space in a building. Proper ventilation helps regulate temperature and moisture levels, preventing issues like mold growth and wood rot. It typically involves the use of vents, fans, and other systems to ensure a continuous exchange of air. Good attic ventilation is essential for maintaining the overall health of a home. It can improve energy efficiency by reducing the load on heating and cooling systems. Additionally, it helps protect roofing materials and extends the lifespan of the roof by minimizing heat buildup and moisture accumulation.
