The 4 Seasons PRO is designed and built specifically for sloped shingled roofs and offers extra protection in severe weather. The vent works by using the sun’s energy to power a fan which pulls excess heat, moisture and humidity out of the attic space while promoting air circulation inside.

It is excellent for steep roof applications. The unique shape helps prevent wind driven rain and snow from blowing into the attic while the slanted hood deflects running rainwater. This vent is the right fit for areas affected by extreme weather conditions. The vent can operate from dawn until dusk, even in low light conditions and will operate as a large, weather resistant ‘passive’ vent after sun down.
