Gibraltar Building Products 1320 CFM Weatherwood Power Roof Mount Attic Ventilator

Electric-powered attic vents use a thermostat to monitor heat and moisture build-up inside the attic. Featuring a low-profile dome, the power attic vent is unobtrusive when installed on the roof slanting away from the front of your home. It's an efficient option to replace wind turbines or roof pots already in place.
