Expert Verdict — Reviewed by the SuperArbor Pro Desk
Four-pound lead is a versatile weight for most flashing details, offering good formability while holding shape once dressed. Lead expands and contracts significantly with temperature, so avoid pinning it tightly and allow for movement at laps. Note that lead should not be used in contact with dissimilar metals such as aluminum or galvanized steel without an isolating layer, and follow local code on lead use near potable water.
Lead requires careful handling—wear gloves, avoid inhaling lead dust when cutting or soldering, and wash hands after handling.
