DuraPlus Flat Roof Flashing

The Roof Flashing is designed to weatherproof the penetration of chimney pipe through the roof, ensuring a secure and leak-free installation. A Storm Collar is required for proper sealing. Choose the appropriate roof flashing based on the pitch of your roof—for example, a 6/12 pitch indicates a vertical rise of 6” over a horizontal distance of 12”. Made of durable galvalume, this flashing is available in 6” and 8” diameters to fit a variety of chimney installations. Additional DuraPlus Info: DuraPlus is engineered to maintain a cooler exterior while promoting a hotter draft inside, enhancing stove efficiency and ensuring a fire-safe design that safeguards both the chimney and the surrounding structure. This triple-wall chimney features two layers of insulation: a ceramic blanket and an air gap. The ceramic blanket insulation is securely positioned, preventing the hot spots often caused by loose-fill insulation types. In the event of a creosote fire, the compressible insulation allows the chimney liner to expand outward radially. Built to withstand continuous operation at 1000°F flue gas temperatures, DuraPlus meets the rigorous UL standards, including one hour at 1400°F and three ten-minute chimney fire tests at 2100°F.
