To enhance structural integrity

To reduce heat and moisture buildup in the attic

The primary purpose of a roof ventilation system is to reduce heat and moisture buildup in the attic. Proper ventilation allows for the movement of air, which helps maintain a balanced temperature and humidity level within the attic space. When heat and moisture are not adequately vented, conditions can lead to various problems, such as ice dam formation in colder climates, deterioration of roofing materials, and mold growth due to excess moisture. By facilitating airflow, the ventilation system helps prevent these issues and extends the life of the roof and overall building structure.
