Why choose Code 3 360mm 6m Roofing Lead?

The code 3 360mm x 6m roofing lead roll is an extremely versatile medium-width option suited to a wide range of roofing applications, including chimney flashings, soakers, abutments, and dormer weatherings. Offering more surface area than 300mm rolls but still retaining the lightweight flexibility of Code 3, this size is ideal for installers who require excellent workability without sacrificing coverage.

Manufactured to BS EN 12588, the code 3 360mm x 6m roofing lead ensures stable thickness, reliable durability and easy on-site dressing. The lightweight profile makes it particularly popular for domestic roofing, heritage reinstatement, small commercial buildings and agricultural structures.

The long 6m roll format significantly reduces the number of joints in a run, improving waterproofing, speeding up installation and achieving a cleaner finish—especially important around chimneys and long abutment lines.

Why a 6m roll is a major installation advantage

A major benefit of the code 3 360mm x 6m roofing lead is the ability to create long flashing runs with minimal joints. Fewer joints reduce the risk of water ingress and significantly improve installation speed and long-term performance.

• Fewer laps improve waterproofing reliability.
• Less cutting and forming reduces labour time.
• Cleaner, more consistent finish around visible details.
• Reduces waste on medium-length roof runs.
• Ideal for dormers, chimney skirts, and long abutment flashings.

Installation guidance & best practice

Despite being lightweight and highly workable, code 3 360mm x 6m roofing lead must still be installed according to BS EN 12588 and LSTA/LSA recommendations. Allowance for thermal movement, correct lap formation and careful dressing are essential.

Avoid stretching the sheet when dressing it into deep or complex profiles. All exposed leadwork should be treated immediately with patination oil to prevent carbonate staining.

Chases should be sealed using either mortar or
Lead Mate Sealant for a durable, clean finish.

Installation essentials

1. Substrate preparation: Ensure flat, smooth, fully supported surfaces.
2. Dressing technique: Form the lead without overstretching.
3. Fixing method: Use copper or stainless nails from our
   Leadwork Fixings Collection.
4. Chase sealing: Finish with mortar or Lead Mate Sealant.
5. Protection: Apply patination oil immediately after installation.
