Roofing Ventilation

Cyclone ventilation—commonly known as turbine ventilators, whirlybirds, or rotary roof ventilators—refers to wind-driven systems designed to exhaust heat, moisture, smoke, and fumes from buildings without consuming electricity. Installed on the highest points of a roof, they spin using a combination of natural wind movement and thermal convection (hot air rising), creating a continuous suction that pulls stagnant air out of the property.
