Roof vents are openings or devices installed on the roof of a house to allow for proper ventilation of the attic or upper spaces. They help regulate temperature and moisture by allowing hot air, humidity, and moisture to escape, while drawing in cooler air from outside. This helps prevent issues like mold growth, ice dams, and overheating in the attic, improving energy efficiency and the lifespan of the roof. Common types of roof vents include ridge vents, static vents, and turbine vents, each designed to facilitate airflow and enhance ventilation.
