Why choose Code 4 210mm 3m Roofing Lead?

The code 4 210mm x 3m roofing lead is an excellent choice for roofing details requiring a wider flashing than standard 150mm or 180mm rolls. At 210mm wide, this roll provides generous lap coverage for stepped flashings, deeper chases, chimney detailing and larger soakers on slate and tile roofs. The added rigidity of Code 4 thickness gives improved longevity, resilience and weather protection—ideal for exposed or high-impact locations.

Produced to BS EN 12588, every roll of code 4 210mm x 3m roofing lead benefits from consistent thickness and predictable performance. It dresses neatly into complex junctions while retaining enough stiffness to resist wind uplift and thermal movement. For tradespeople ordering on the go, our streamlined
Lead Flashing Calculator makes it fast and simple to select the correct width and code.

Typical uses for Code 4 210mm 3m Roofing Lead

• Deeper stepped flashings to brick or stone abutments.
• Large individual soakers for tile and slate roof coverings.
• Chimney aprons, back gutters and weathering strips.
• Dormer cheeks, roof interfaces and window head protection.
• Heritage reinstatement requiring a robust, traditional rolled lead finish.

Good practice with Code 4 210mm 3m Roofing Lead

Because code 4 210mm x 3m roofing lead provides extra width, it is important to manage bay lengths to prevent fatigue. Keep lengths within recommended limits and always dress neatly into chases and roof junctions. Use correct pointing materials for protection and a crisp finish, and apply patination oil after installation to minimise early staining. For more demanding weatherings, consider pairing with suitable underlayers from our
Lead Underlay collection.
