DuraVent DuraTech DSA Roof Flashings: a bendable base for metal or tile roofs
The DuraVent DuraTech DSA Roof Flashings is a roof covering for the opening around your chimney. DSA means dead soft aluminum. The base can be bent by hand around metal roofing ribs or curved clay tiles where stiff flashing cannot seal. 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. Its sections twist together without screws or bands at the joints. A locking band is optional.
Choose a 6 or 8 inch chimney size, then a roof pitch range: 0/12 to 6/12 or 7/12 to 12/12. Pitch measures inches of rise over 12 inches of run. A separately sold storm collar fits above the flashing. A straight chimney needs at least 10 to 15 feet above the stove outlet. The cap must sit 3 feet above the roof exit and 2 feet above anything within 10 feet. Have a shingle roof? See the DuraVent DuraTech Roof Flashing for shingles. The DuraVent DuraTech DSA Roof Flashings ships free from My Cozy Outdoors with No Sales Tax (except WY) and the full manufacturer warranty.
