Expert Verdict — Reviewed by the SuperArbor Pro Desk
No-caulk flexible plastic flashings are the fastest vent-pipe fix for repairs and re-roofs, and they conform easily to irregular roof planes. Slide the collar fully over the pipe and integrate the base into the shingle courses so water sheds over, not under, the flange. Match the collar to the actual pipe OD, since an oversized collar may not seal.
Roof work requires fall protection and awareness of weather conditions; ensure the flashing is lapped correctly with underlayment and shingles for a watertight installation.
Order the Oatey Flex-Flash No-Calk Roof Flashing for a caulk-free, watertight vent pipe seal.
