Attic Ventilation
Attic ventilation refers specifically to airflow within the attic space beneath the roof deck. It ensures that hot, moist air does not become trapped, which can lead to insulation damage, mold growth, and structural decay. In regions like British Columbia, attic ventilation is essential due to frequent rainfall and temperature fluctuations. Proper attic ventilation systems help regulate indoor comfort, reduce energy costs, and protect roofing components from moisture-related damage. It is typically achieved through a combination of soffit vents, ridge vents, and mechanical ventilation systems when required.
