Why choose the Premium Code 4 360mm 6m Roofing Lead?

The code 4 360mm x 6m roofing lead is a wide-format, long-length rolled lead sheet designed for demanding roofing applications where superior coverage, fewer joints and enhanced durability are essential. At 360mm wide and 6m long, this premium roll is ideal for parapet walls, chimney back gutters, deep abutments, large soakers and wide weathering details across both heritage and modern roofing projects.

Manufactured in accordance with BS EN 12588, each roll of code 4 360mm x 6m roofing lead offers guaranteed thickness consistency, excellent malleability and long-term performance. Code 4 is widely recognised as the best all-round gauge for flashing, weathering and general roofing work because it provides the perfect balance of strength and workability.

The 360mm width is a significant upgrade from narrower rolls, giving installers more flexibility and improved water management on details that require extra upstand height or extended horizontal coverage. Whether used on chimneys, parapets, dormers or wide junctions, this roll offers exceptional efficiency on-site.

Typical uses for Code 4 360mm 6m Roofing Lead

The benefits of upgrading to a 6m long roll

When compared to 3m lengths, the code 4 360mm x 6m roofing lead offers significantly fewer joints, faster installation and a streamlined professional finish. For structural details such as parapets, chimney gutters and long abutments, continuous coverage is a major performance advantage.

The 6m format:

• reduces installation time by eliminating repetitive cutting
• reduces the number of laps, improving water management
• improves aesthetic continuity across long runs
• reduces labour costs on all roof types

For large commercial roofs, listed buildings, traditional reinstatement and new-build developments, the 6m roll is the preferred choice.

Good practice when installing 360mm lead

Because code 4 360mm x 6m roofing lead is a wide-format sheet, correct preparation and support are critical. Ensure the substrate is smooth, fully supported and free from sharp projections. Follow Lead Sheet Association guidance when forming drips, laps and joints.

Avoid stretching the lead while dressing, as this may reduce its effective thickness. Apply patination oil immediately after installation to prevent carbonate staining and ensure uniform early weathering.

Seal chases with mortar or a neutral-cure sealant like
Lead Mate Sealant.

Installation essentials

1. Prepare the substrate: Ensure smooth, full support across the full 6m length.
