Expert Verdict Reviewed by the SuperArbor Pro Desk

Choose lead flashing when a formable, long-lasting boot is needed for irregular penetrations; for 1-1/4″ pipes this L-Series size fits directly, but verify local code allows lead. Dress the lead snugly over the pipe and lap the base into the shingle courses per the manufacturer’s detail. Lead is heavy and soft, so avoid dragging it across the finished roof and keep it from contacting dissimilar metals where galvanic corrosion is a concern.

Lead requires safe handling: wear gloves, wash hands after use, and follow OSHA lead-handling practices on site.
