Expert Verdict — Reviewed by the SuperArbor Pro Desk
Size ARF flashing to the outer diameter of the double-wall flue pipe and set the adjustable base to the roof pitch before securing it. Galvanized steel is the right call where aluminum could react with dissimilar metals or where flue heat demands the stouter material. Integrate the uphill flange into the shingle course above and seal all fastener penetrations to keep the penetration watertight.
Flue penetrations carry heat; maintain required clearances to combustibles and follow local building and fire codes, using fall protection when working on the roof.
Order the Hercules Galvanized Adjustable Roof Flashing for a durable, code-minded seal on flue pipe penetrations.
