DuraVent DuraTech Roof Flashing: a roof seal chosen to match your roof’s slope
The DuraVent DuraTech Roof Flashing is a metal skirt that closes the opening around your chimney on a shingle roof. Choose it to match your roof’s slope. DuraTech is DuraVent’s double wall chimney, an insulated pipe with a 1 inch wall that takes over from the stovepipe at the ceiling or wall and runs up past the roof. It serves wood, coal, oil, or gas appliances, such as stoves and furnaces, with one appliance per chimney. Leave 2 inches of open air between the chimney and anything that can burn, including framing and insulation.
Choose a 5, 6, 7, or 8 inch size, then your roof pitch. Pitch measures rise over 12 inches of horizontal run. For example, 6/12 rises 6 inches. Options are flat roof, 0/12 to 6/12, 7/12 to 12/12, 13/12 to 18/12, and 19/12 to 24/12. The two lower pitch ranges offer a wider base for larger openings in 6, 7, and 8 inch sizes. You also need the separately sold DuraVent DuraTech Storm Collar, a ring above the flashing. The DuraVent DuraTech Roof Flashing ships free from My Cozy Outdoors with No Sales Tax (except WY) and the full manufacturer warranty.
