Expert Verdict — Reviewed by the SuperArbor Pro Desk
Choose 4 lb. lead for most step and chimney flashing details; heavier weights are reserved for higher-wear areas. Form lead gently to avoid thinning the sheet, and never use it where runoff contacts dissimilar metals that corrode with lead. Confirm code acceptance, as some jurisdictions restrict lead flashing.
Lead exposure is a health hazard: wear gloves, avoid handling with bare skin, wash hands after use, and follow safe work practices when cutting or heating lead.
