A ridge vent is a type of roof ventilation system installed along the peak of a sloped roof. It allows hot air and moisture to escape from the attic, helping to regulate temperature and prevent damage from excess humidity. Ridge vents are typically covered with a protective cap to keep out rain and debris while still allowing airflow. These vents work best when combined with soffit vents, which are located at the eaves of the roof. This combination creates a continuous flow of air, promoting better ventilation throughout the attic space. Proper ventilation can extend the life of the roof and improve energy efficiency in the home.
