An exterior house vent is used to eliminate moisture and mold problems that occur within the structure of the home. Exterior house vents help prevent structural damage and ensure that areas in the home, such as attics or crawl spaces, remain dry and secure.
Many functions inside the home create fumes, heat and moisture that lead to damage. For example, cooking moisture can leave stains and grease on walls or ceilings. An exterior vent can help remove the moisture that causes these problems. Exterior roof vents help guarantee that an attic remains dry, which prevents structural damage and eliminates the possibility of mold forming from excess moisture. Additionally, many appliances, such as heating systems and dryers, require exterior vents to ensure safety.
