Why choose code 5 1000mm 6m roofing lead?

The code 5 1000mm 6m roofing lead roll is a heavy-duty, wide-format sheet engineered for large roof coverings, parapet tops, wide gutters and heritage-grade weatherings requiring maximum durability. At 1000mm wide and a substantial 6m long, this roll provides significant coverage while delivering the strength, movement resistance and long-term reliability associated with Code 5 gauge lead.

Manufactured to BS EN 12588, this product offers consistent thickness (approx. 2.24mm), premium corrosion resistance and excellent mechanical performance. Installers specify code 5 1000mm 6m roofing lead for demanding applications where the sheet functions as a primary waterproof covering rather than a flashing.

The extended 6m length enhances installation efficiency by reducing the number of joints, seams and bay transitions required across long runs. This delivers cleaner visual lines, fewer potential leak points and faster progress on site.

Typical uses for code 5 1000mm 6m roofing lead

Due to its significant width and heavy-duty gauge, this roll is frequently chosen for:

• Large bay roofs requiring full-width Code 5 coverage.
• Parapet and boundary wall cappings on heritage or premium projects.
• Wide gutters, sumps and high-capacity drainage channels.
• Dormer tops, roof projections and curved architectural elements.
• Structural weatherings over stone details, cornices and façades.
• Full-surface coverings on listed or architecturally important buildings.

Design considerations for Code 5 wide coverings

The increased width of code 5 1000mm 6m roofing lead requires careful bay design. Sheets of this size must be divided into manageable bays with correct drips, welts, laps and movement joints to prevent fatigue cracking and improve long-term stability.

• Split coverings into bays following LSTA/LSA bay sizing guidance.
• Use drips on long, flat or low-pitch surfaces.
• Install over a suitable
  Lead Underlay to minimise underside corrosion.
• Ensure proper falls to eliminate ponding.
• Add access boards where occasional maintenance traffic is anticipated.

Installation guidance

As one of the heaviest wide-format sheets, this product must be handled and installed by trained operatives in accordance with BS EN 12588 and LSTA/LSA leadwork recommendations. Two-person handling is strongly recommended for safety and accuracy.

Once installed, code 5 1000mm 6m roofing lead should be treated with patination oil to promote uniform weathering and reduce early carbonate staining.

For chase sealing, detailing and perimeter jointing, choose traditional mortar or
Lead Mate Sealant.

Installation essentials

1. Prepare the substrate: Use a smooth, rigid deck with correct underlay.
2. Set out bays: Divide coverings into recommended bay sizes.
3. Fix correctly: Use stainless or copper fixings from our
   Leadwork Fixings range.
4. Seal joints: Finish with mortar or Lead Mate Sealant.
5. Finish the surface: Apply patination oil immediately.
