Designed to enhance roof ventilation, turbine vents alleviate hot air from attics, relying on wind blowing across roofs to remove the air and replace it with cooler air through convection. Turbine vents also keep rain, snow and insects from entering attics. Purchasing the best vent is important for maintaining a properly ventilated attic.
