Why choose code 5 360mm 6m roofing lead?

The code 5 360mm 6m roofing lead roll is a highly versatile heavy-gauge sheet suitable for wide flashings, parapet coverings, valley details and structural weatherings. At 360mm wide, it offers significantly more coverage than narrow widths while still being manageable to dress cleanly on site. Its 6m length reduces the need for joints and provides long, uninterrupted runs of weatherproof detailing.

As a BS EN 12588 rolled lead sheet, the code 5 360mm 6m roofing lead delivers uniform thickness (approx. 2.24mm), predictable shaping characteristics and exceptional durability. BS EN 12588 defines the material properties and tolerances, while workmanship and detailing should follow recognised guidance such as the LSTA manual and BS 6915.

Installers favour this width for chimney aprons, parapet flashings, roof abutments and premium heritage projects requiring a robust, long-lasting material with excellent fatigue resistance and structural stability.

Typical uses for code 5 360mm 6m roofing lead

This wider roll format is ideal for applications that require extra coverage and strength, including:

• Wide chimney aprons and stepped flashings.
• Valley weatherings and central roof junctions.
• Parapet and boundary wall coverings.
• Dormer tops and cheek weatherings.
• Large soakers and protective wall flashings.
• Traditional detailing for listed or conservation projects.

Why Code 5 is the professional choice for wide weatherings

Wider flashings and coverings must withstand greater movement forces, especially where long runs are exposed to direct sunlight. The code 5 360mm 6m roofing lead provides installers and specifiers with:

• Enhanced thickness for structural stability.
• Reliable performance on exposed elevations.
• Long service life when detailed to LSTA/BS 6915 guidance.
• Resistance to fatigue cracking over time.

This makes Code 5 the preferred option for wider details that cannot rely on lighter gauges such as Code 3 or Code 4, particularly on high-value domestic and heritage roofing work.

Installation guidance

Install code 5 360mm 6m roofing lead in accordance with the workmanship principles set out in the Lead Sheet Training Academy (LSTA) / Lead Sheet Association (LSA) manuals and guidance aligned with BS 6915. BS EN 12588 governs the material standard; it does not define workmanship. Thermal expansion allowances are especially important with wider sheets, and correct bay sizing must always be used for long-term performance.

After shaping and fixing, apply patination oil to protect the sheet during early oxidation and to ensure consistent weathering across the installation.

For sealing chases and junctions, use mortar or
Lead Mate Sealant
depending on the substrate and required finish.

Installation essentials

1. Prepare the surface: Ensure smooth, debris-free support and correct underlay beneath the lead.
2. Cut bays correctly: Keep lengths appropriate for Code 5 movement behaviour in line with BS 6915 guidance.
3. Use correct fixings: Choose copper or stainless nails from
   Leadwork Fixings and avoid over-fixing.
4. Seal securely: Finish with mortar or Lead Mate for robust detailing at chases and terminations.
5. Protect the finish: Apply patination oil immediately after installation to all exposed lead surfaces.
