Roof ventilation is the process of allowing air to flow in and out of a building's attic space. This helps to regulate temperature and moisture levels, preventing heat buildup in the summer and reducing the risk of ice dams in the winter. Proper ventilation can also extend the lifespan of roofing materials and improve energy efficiency. There are two main types of roof ventilation: intake vents and exhaust vents. Intake vents allow fresh air to enter, while exhaust vents let warm, stale air escape. Together, they create a balanced airflow that helps maintain a healthy and comfortable indoor environment.
