Expert Verdict — Reviewed by the SuperArbor Pro Desk
Pick the smallest size range that fits your pipe for the tightest seal, and match color to your shingles — Weathered Wood suits architectural shingles, Black suits most composition roofs. Because the collar stretches, it seals on the pipe even with slight out-of-square installs. Integrate the skirt into shingle courses with laps matching the surrounding shingles, never just surface-mounted.
Do not over-stretch the collar beyond its stated pipe range, as tearing the flexible material risks a poor seal and leaks.
Order the Duraflo StretchFit Pipe Flashing and cover multiple pipe sizes with one flexible flashing.
