GAF's new Master Flow Bath & Dryer Rooftop Appliance Vent is an innovative solution engineered to efficiently vent heat and moisture from bathroom and kitchen exhaust fans, clothes dryers, and other household appliances.

Designed to help safeguard your home, this vent can help improve indoor air quality and reduce the risk of costly moisture damage. Engineered for high performance, the Master Flow Bath & Dryer Rooftop Appliance Vent passes rigorous 110 mph wind-driven rain testing in accordance with TAS-100(A)¹, ensuring reliable operation even in severe weather conditions. It also meets building codes that require a minimum of 12.5 square inches of net-free ventilation area for rooftop bath, dryer and appliance vents.

Offering versatility and ease of use, the vent features a removable stainless steel bird/pest screen, as well as a convenient duct collar. This smart design simplifies duct connection, allowing for hassle-free lint and dust removal without the need to climb on the roof.

GAF offers up to a 50-year limited warranty against manufacturing defects and it's also eligible for enhanced warranty coverage when installed by a GAF-certified contractor in conjunction with a GAF enhanced warranty³.
