Expert Verdict Reviewed by the SuperArbor Pro Desk

Size the flashing to the pipe diameter; an oversized lead sleeve can be formed down, but an undersized one cannot be stretched. Press the lead down into the pipe mouth and fold the top edge inward so wind-driven rain cannot run behind it. Keep the exposed lead above the shingle course to maintain the seal.

Lead requires careful handling; wear gloves, avoid skin contact and follow local codes regarding lead flashing materials.
