Knowing exactly what size vent pipes will be at a job site when you arrive is not always possible. With Duraflo® 5-in-1 roof flashing you carry 1 roof flashing in inventory instead of 5.
Install over a 1-1/4, 1-1/2, 2, 3 or 4-inch plumbing vent stack to seal the roof opening. Press fit application, no sealant needed. The flashing will be secured to the roof and shingled around as part of the roofing application. The flexible base has a tear-away and size adjustable vent pipe opening
