Expert Verdict — Reviewed by the SuperArbor Pro Desk
Galvanized pipe flashing is a durable, economical choice for standard plumbing vent penetrations on asphalt shingle roofs. Install it in shingle courses so the flange laps over the underlayment below and under the shingles above, and seal the collar to the pipe where required. For exposed metal roofing or high-visibility installs, consider a painted or lead alternative to better match the roof.
Roof work carries fall hazards; use proper fall protection and follow local codes when installing flashing.
