Roof ventilation functions by promoting air circulation within your attic space. It relies on the natural tendency for warm air to rise and cool air to settle, creating a continuous airflow.
- Prevent ice dams in cold climates - Reduce humidity and moisture issues in hot climates - Improve overall energy efficiency
- Ridge vents - Soffit vents - Gable vents - Roof louvers (box vents) - Wind turbines (whirlybirds) - Power vents - Off-ridge vents - Cupola vents
- Passive Ventilation: Passive ventilation relies on natural forces, such as wind and convection, to circulate air in the attic. - Active Ventilation: In contrast, active ventilation uses powered attic ventilators to draw fresh air from outside and push it into the attic while simultaneously expelling the hot air.
