FlashCo L-Series Adjustable Lead Pipe Flashing, 2.5# Lead, 1-1/2 in. or 4 in. Pipe Sizes
FlashCo's L-Series adjustable lead flashing seals round roof penetrations with an all 2# lead construction and a standard 12 in. riser. The base wraps up into the riser to shed water away and provide a watertight seal. Choose 1-1/2 in. or 4 in. pipe size; sold per piece.
Key Features:
- All-Lead Construction: Built from all 2# lead for mass, malleability, and long-lasting performance.
- Watertight Seal: Provides a watertight seal that completely protects round roof penetrations.
- Adjustable Riser: The cylindrical lead riser matches the penetration shape and can be adjusted and formed in place.
- No Penetrating Fasteners: Lead's mass, malleability, and expansion/contraction eliminate the need for penetrating fasteners.
- No Electrolysis: No dissimilar-metal fasteners or steel boots are needed, eliminating electrolysis concerns.
- Fast Installation: Installation time is minimal since lead does not need to be fastened to the insulation or roof deck.

Expert Verdict — Reviewed by the SuperArbor Pro Desk
Pick the L-Series for round plumbing vents and stacks where a malleable, conforming flashing is preferred over molded rubber boots, especially on standing-seam or tile roofs where lead can be dressed to the profile. Form the riser down into the pipe and shape the base to the roof surface. Size the flashing to the pipe diameter so the lead grips without gaps.
Lead requires safe handling: wear gloves, wash hands after use, and avoid cutting or heating lead without proper ventilation.
