Roof vents help remove moisture from homes, and, in warmer regions, help remove heat build-up in attics. Vents are essential components for keeping a roof safe from moisture and mold.
While some people in areas that rarely get warm are concerned about losing heat through roof vents, a properly installed system minimizes any losses. The cost of a premature roof replacement negates any potential savings.
In addition, the best way to prevent the loss of heat through an attic is to install sufficient insulation and seal potential leakage spots. Doing so also prevents heating and cooling systems from wasting energy heating or cooling the attic.
