Why choose code 5 760mm 3m roofing lead?

The code 5 760mm 3m roofing lead roll is a premium heavy-gauge sheet widely specified for parapet cappings, deep weatherings, wide flashings, gutter linings and vertical cladding details. At 760mm wide, it provides extensive coverage while remaining manageable to dress on site, making it a staple for specialist leadworkers and heritage contractors.

Produced to the BS EN 12588 rolled lead standard, this sheet offers consistent thickness (approx. 2.24mm), reliable weight distribution and excellent malleability during forming. While BS EN 12588 specifies material quality, all installation and detailing must follow the craftsmanship principles set out by the Lead Sheet Training Academy (LSTA) and the national detailing standard BS 6915.

The 3m length allows installers to create multiple bay sections from a single roll, providing both efficiency and accuracy when working on parapets, valleys, sumps and cladding panels.

Typical uses for code 5 760mm 3m roofing lead

This wider Code 5 roll is suitable for a wide range of structural weathering tasks, including:

• Parapet cappings with deep upstands and extended cover sections.
• Deep cladding and welted panel systems on dormers and façades.
• Wide flashings to walls, chimney stacks and pitched roof interfaces.
• Gutter linings, sumps and channels requiring robust heavy-gauge lead.
• Bay roofs and architectural projections.
• Complex weathering details where flexibility and strength are essential.

Why Code 5 is chosen for wider structural leadwork

Wider and more exposed weatherings demand a heavier gauge to withstand environmental stress and ongoing thermal movement. Code 5 760mm 3m roofing lead provides:

• Excellent fatigue resistance under repeated movement cycles.
• Enhanced rigidity for large or deep cover details.
• High durability suitable for heritage and conservation roofing.
• Reliable stability when forming welts, drips, laps and cladding panels.

Installed in accordance with LSTA and BS 6915 workmanship standards, Code 5 offers exceptional long-term performance on both residential and commercial projects.

Installation guidance

Install code 5 760mm 3m roofing lead using the LSTA manuals and the detailing principles within BS 6915, which define thermal movement requirements, joint types, lap sizes, fixings and bay limitations for Code 5 sheets.
