Expert Verdict — Reviewed by the SuperArbor Pro Desk
Choose a pipe flashing diameter that matches the vent pipe, so the collar seals snugly without excessive gap filler. On shingle roofs, embed the flashing base in roofing cement or compatible sealant and integrate it into the shingle courses so water sheds around, not into, the penetration. For larger vent stacks, step up to the matching larger diameter rather than forcing an undersized collar.
Work on roofs only with proper fall protection, and follow local building codes and the pipe manufacturer's sealing instructions when flashing penetrations.
