Why choose the Premium Code 4 760mm 6m Roofing Lead?

The code 4 760mm x 6m roofing lead is one of the widest long-length rolled lead formats available in the Code 4 range, offering exceptional coverage for large and technically demanding roofing applications. At 760mm wide, this premium roll is ideal for deep parapet walls, box gutters, chimney weatherings, wide abutments, dormer structures, flat roof transitions and substantial heritage detailing.

Manufactured to BS EN 12588, the code 4 760mm x 6m roofing lead ensures reliable thickness uniformity, excellent malleability and long-term durability. Code 4 is the go-to specification for large flashings and general roofing work due to its balance of strength and flexibility—critical at larger widths where structural performance becomes increasingly important.

This width is chosen when standard sizes such as 450mm, 510mm or even 600mm are not sufficient to achieve the required lap height or to cover more complex junctions. It replaces the need for multiple narrower sheets, reducing risk and improving long-term weathering.

Typical uses for Code 4 760mm 6m Roofing Lead

• Deep parapet wall flashings requiring extensive vertical coverage.
• Large chimney back gutters, aprons and oversailing details.
• Box gutter linings over long or wide sections.
• Dormer cheek and slope transitions on larger structures.
• Wide abutment flashings on pitched or flat roofs.
• Complex detailing on listed or heritage buildings.
• Situations where narrower rolls require excessive joints.

The advantages of choosing a 6m long roll

Because the code 4 760mm x 6m roofing lead delivers so much coverage in a single length, it massively reduces the number of joints required. This simplifies installation, improves water management and produces a much cleaner finish.

Major benefits of the 6m format include:

• Substantially fewer joints than traditional 3m rolls.
• Superior waterproofing performance across long distances.
• Faster installation times and reduced labour cost.
• Ideal for high-value properties and sensitive detailing.
• Better aesthetic continuity on visible surfaces.

For large-scale structural weathering, the combination of width and length makes this SKU one of the strongest choices in the Lead Lads range.

Good practice when installing 760mm lead

As one of the widest Code 4 sheets, code 4 760mm x 6m roofing lead requires excellent preparation. Ensure the substrate is smooth, fully supported and free of sharp edges. Larger sheets also require more precise management of thermal expansion.

Follow LSTA/LSA guidelines for lap sizes, drips, fixings and expansion joints to ensure long-term reliability.

Apply patination oil immediately after installation to prevent early carbonation marks and maintain uniform weathering. Seal chases with mortar or a specialist sealant such as
Lead Mate Sealant.

Installation essentials

1. Prepare the surface: Provide full, smooth support for the entire 760mm width.
2. Cut & dress: Shape the code 4 760mm x 6m roofing lead carefully to avoid stretching.
3. Fix correctly: Use copper or stainless nails from our
