Expert Verdict — Reviewed by the SuperArbor Pro Desk
Choose lead flashing when a detail needs on-site forming around irregular masonry or penetrations that pre-fabricated metal flashings cannot follow. Dress the lead with care to keep thickness even at folds, and isolate it from incompatible metals to avoid galvanic corrosion. Keep a 4 lb. weight for typical step and base flashing work and step up for larger or more exposed details.
Lead requires careful handling: wear gloves, avoid skin contact and inhalation of dust or fumes when cutting or soldering, and follow local codes for lead flashing work.
