This 10-inch adjustable roof flashing is engineered to provide a secure, weather-tight penetration through roof structures for Type B gas vent pipes. Sized for standard 10-inch inner diameter venting, it accommodates roof pitches from flat up to 6/12, helping prevent rain, snow, and ambient moisture from bypassing the structural envelope and entering the building interior.
Constructed with durable materials, this flashing is designed for use alongside Category 1 gas-burning appliances, including high-efficiency residential furnaces, water heaters, boilers, pool heaters, and gas fireplaces. It features an operating threshold capable of handling continuous flue gas temperatures up to 243 degrees Celsius, providing long-lasting resilience when venting natural gas or liquid propane equipment.
HVAC contractors and roofing professionals specify this adjustable roof component to simplify complex roof terminations and ensure structural sealing integrity. The double-seamed configuration minimizes manual adjustments on-site, making it a reliable choice for completing commercial or residential gas appliance venting projects where proper component alignment and long-term durability are critical.
