Expert Verdict Reviewed by the SuperArbor Pro Desk

Lead flashing is the go-to where the detail must be dressed and re-dressed over irregular masonry, and the 4 lb weight class gives good working stiffness for a 2″ width. Form it with hand tools rather than stretching thin areas, and isolate it from incompatible substrates. Confirm your local code permits lead before specifying.

Lead requires careful handling: wear gloves, wash hands after handling, avoid creating dust or fumes, and follow local regulations for lead products.
