The Master Flow Green Machine Solar Powered Ridge Vent sits unobtrusively on the roof and circulates 25 times more attic air than traditional ridge vents, the company says. By capturing the sun’s energy, the ridge vent eliminates the operating costs of electrically powered vents and lightens the load on the home’s air conditioning system. GAF. 877.423.7663. www.gaf.com.
