DuraVent PolyPro Variable Pitch Roof Flashing: covers the roof opening around a commercial vertical termination
The DuraVent PolyPro Variable Pitch Roof Flashing is a stainless steel cover that helps keep weather out where the vent passes through the roof. It works with the commercial vertical termination, the part that ends the vent above the roof. This flashing suits flat roofs and sloped roofs up to a 9/12 pitch. The support clamp rests in a groove with notches on the flashing, with the storm collar above it. Choose a 5, 6, or 8 inch size on this page to match your vent.
PolyPro is DuraVent’s polypropylene vent pipe for high efficiency condensing gas boilers, furnaces, and water heaters. Standard gray PolyPro parts belong indoors. Outdoor elbows, tees, and terminations are black to resist damage from sunlight. The appliance manufacturer determines the allowed vent length and number of elbows, so those limits matter when planning the route to the roof. Need the clamp that sits on this flashing? See the DuraVent PolyPro Support Clamp for the Commercial Vertical Termination. The DuraVent PolyPro Variable Pitch Roof Flashing ships free from My Cozy Outdoors with No Sales Tax (except WY) and the full manufacturer warranty.
