Attic Ventilation 1. Soffit Vents located at the eave of a roof, permit generous airflow to the rafter space as they act as the intake to the attic’s ventilation.
Attic Ventilation 2. Ridge Vent Ridge Vents, located at the highest point of a roof, allows air to be exhausted while still protecting the attic from weather.
Attic Ventilation 3. Gable Vent located high in the wall at opposite ends of an attic. Gable vents create a cross draft to help ventilate the attic.
Attic Ventilation 4. Roof Turbines Roof Turbines use wind to expel air out of the attic to ensure the moist air does not settle in the attic and begin to mold .
