Flawless shingle installation is expected in professional roofing. What truly sets contractors apart? Subtle upgrades that enhance a home’s curb appeal and functionality.
Get the best of both worlds with the all-new Master Flow™ Bath & Dryer Rooftop Appliance Vent from GAF.
Easy on the eyes and hard as nails, this premium, all-metal rooftop appliance vent provides leak resistance and efficiently vents heat and moisture from bathroom and kitchen exhaust fans, clothes dryers,1 and other household appliances through the roof.
With its sleek, modern design and four color options — Black, Brown, Weathered Wood, and Gray — it seamlessly complements a wide range of popular shingle colors. But it’s not just about looks. This premium solution combines form and function, meeting building codes2 that require a minimum of 12.5 square inches of net-free ventilation area for rooftop bath, dryer, and appliance vents — a benefit customers will love.
Tested tough, it provides durability in harsh environments and passes rigorous 110 mph wind-driven rain testing in accordance with TAS-100(A).3 Plus, it’s warrantied against manufacturing defects for up to 50 years or as long as the warranty of the adjacent roof cladding.4
A removable duct collar, a 4” to 3” reducer, and removable stainless steel bird/pest screen for easy installation and hassle-free cleaning.1
