Roof ventilation is the controlled movement of air through the attic and roofing system to regulate temperature and moisture levels. It plays a critical role in preventing heat buildup during summer and reducing condensation during colder months. In climates like Vancouver, where humidity and rainfall are high, proper roof ventilation helps prevent mold growth, wood rot, and premature deterioration of roofing materials. A balanced ventilation system typically includes intake vents and exhaust vents working together to maintain continuous airflow. Effective roof ventilation also improves energy efficiency by reducing strain on heating and cooling systems, ultimately extending the lifespan of the entire roofing structure.
