Eave vents are openings located at the eaves of a roof, designed to allow air to flow into the attic space. They help maintain proper ventilation, which is essential for regulating temperature and moisture levels in the attic. This ventilation can prevent issues like mold growth and ice dams during winter. These vents work in conjunction with other ventilation systems, such as ridge vents and soffit vents, to create a balanced airflow. By promoting circulation, eave vents contribute to the overall health of a building, enhancing energy efficiency and prolonging the lifespan of the roof and other structural components.
