Duraflo®’s line of easy-to-install thermoplastic base roof flashings will ensure the roof around vent stacks remains leak-free no matter the weather. The flashings simply slide over the pipe and are then pressed to fit in place, requiring no sealant. Duraflo® roof flashings feature built-in water deflectors and are made from UV-resistant and cold-impact-resistant polypropylene. They come in sizes to fit pipes from 1 ½” to 4 " and are available in a variety of colours.
