Why choose Code 4 240mm 3m Roofing Lead?

The code 4 240mm x 3m roofing lead provides an excellent balance of width, strength and flexibility for roofers needing a durable solution for deeper flashings, wider laps and more complex weatherings. At 240mm wide, it offers significantly more coverage than 150–210mm sizes while maintaining the workability and long-term resilience that Code 4 rolled lead is known for. This makes code 4 240mm x 3m roofing lead ideal for larger soakers, chimney detailing, dormer weatherings and extended abutments.

Manufactured to BS EN 12588, this rolled lead delivers consistent thickness and high-quality performance across every metre.
It dresses smoothly into brickwork chases, stone joints and slate/tile interfaces, providing a traditional finish with exceptional longevity.
To simplify ordering, you can calculate exact quantities using our
Lead Flashing Calculator—particularly useful when working on scaffolds or fast-moving jobs.

Typical uses for Code 4 240mm 3m Roofing Lead

• Wider stepped flashings to deep abutments.
• Large soakers for slate and tile roofs requiring increased lap.
• Chimney aprons, back gutters and weatherings with greater exposure.
• Dormer top and cheek protection with extended coverage.
• Conservation and heritage reinstatement where traditional wide rolled lead is specified.

Good practice with Code 4 240mm 3m Roofing Lead

As code 4 240mm x 3m roofing lead offers wider coverage, correct detailing is essential to manage thermal movement. Keep lengths within recommended limits and ensure that laps, welds and junctions shed water effectively. Dress the lead neatly into abutments while avoiding excessive manipulation that could thin or weaken the material. Use a suitable slip layer from our
Lead Underlay category to reduce underside abrasion and promote movement.

Installation essentials

1. Prepare the substrate: Ensure smooth boarding and remove sharp edges before laying the lead.
2. Cut & shape: Form the code 4 240mm x 3m roofing lead with clean edges to maintain tight laps and crisp detailing.
