DuraVent PolyPro 5 to 8 Inch Flat Roof Flashing: keeps water out around a flat roof vent opening
The DuraVent PolyPro 5 to 8 Inch Flat Roof Flashing is a cover for the opening where a vent passes through a flat roof. It keeps water from entering around that opening. This is the larger size range shown with DuraVent’s 5 to 8 inch PolyPro parts. Choose a 5, 6, or 8 inch size on this page to match the size specified for your vent. PolyPro is DuraVent’s polypropylene vent pipe for high efficiency condensing gas boilers, furnaces, and water heaters.
Water inside the vent needs a path out, too. Horizontal PolyPro runs slope back toward the appliance without low spots that could collect condensate, the liquid left by the exhaust. That liquid returns to the appliance or a drain, as directed by the appliance maker. In the USA, the appliance maker must list PolyPro for that appliance, and its venting instructions govern its use. In Canada, DuraVent lists PolyPro as a vent system in its own right. Looking for a vent outlet? See the DuraVent PolyPro Vertical Termination for Commercial Systems. The DuraVent PolyPro 5 to 8 Inch Flat Roof Flashing ships free from My Cozy Outdoors with No Sales Tax (except WY) and the full manufacturer warranty.
