Expert Verdict — Reviewed by the SuperArbor Pro Desk
Aluminum double-wall pipe flashings are a dependable choice for residential vent penetrations because they hold shape and resist corrosion. Install them as shingle courses approach the pipe, lapping the skirt into each course, and use a compatible sealant at the pipe-to-collar joint. Confirm pipe diameter against the 4 in. unit before ordering.
Check the pipe's temperature rating: aluminum flashings are for standard vent pipes, not for hot flues that require listed high-temperature flashing.
