Expert Verdict Reviewed by the SuperArbor Pro Desk

The 4 lb Tallco is a good pick when you want a more robust, taller boot than a standard lead flashing, especially on steeper roofs where more sleeve height helps. Shape the base with a flat bar to track the shingle courses and fold the pipe end inward to block water paths. Keep lead flashing clear of copper runoff concerns by matching metals where practical.

Lead requires careful handling; wear gloves, avoid inhalation of lead dust when cutting, and follow local codes.
