Why choose code 5 800mm 6m roofing lead?

The code 5 800mm 6m roofing lead roll is a highly adaptable heavy-gauge sheet widely used for gutter linings, roof channels, smaller lead bays, flat or pitched roof coverings and larger-scale vertical cladding in welted panel systems. The extra-wide 800mm format combined with a long 6m length gives installers maximum flexibility when cutting compliant bay sections, reducing waste and ensuring consistent performance.

Manufactured to BS EN 12588, this rolled lead offers consistent thickness and weight tolerance, making it reliable to form, dress and detail. While BS EN 12588 defines the material properties, all installation must follow the workmanship principles set out by the Lead Sheet Training Academy (LSTA) and the national leadwork installation standard BS 6915.

Whether lining gutters and sumps, creating durable weatherings on flat roofs, or applying lead as vertical cladding, code 5 800mm 6m roofing lead provides exceptional longevity thanks to its increased resistance to fatigue and environmental stress.

Typical uses for code 5 800mm 6m roofing lead

This roll size is ideal for a wide range of roofing and cladding tasks, including:

• Gutter linings and deep roof channels where durability is essential.
• Smaller lead bays on flat or low-pitched roof areas.
• Vertical cladding using welted panels for façades, dormers and chimneys.
• Sump and back gutter weatherings on complex interfaces.
• Long-length protective flashings with generous coverage requirements.
• Pitched roof detailing where a heavy-gauge sheet provides long service life.
• General roofing repairs requiring strength and full-width coverage.

Why Code 5 is ideal for gutters, bays and cladding

The heavier 2.24mm gauge of code 5 800mm 6m roofing lead makes it particularly well suited to applications with higher structural demands. This includes areas prone to large volumes of water, fluctuating temperatures, or complex detailing.

• Enhanced fatigue resistance for gutters and channels with continuous water flow.
• Greater rigidity for cladding panels and pitched roof weatherings.
• Improved lifespan in exposed environments.
• Reliable shaping when forming laps, welts and drips.

As a result, this width and gauge combination is frequently used by leadwork specialists for both contemporary and heritage roofing projects.

Installation guidance

All installation of code 5 800mm 6m roofing lead must follow the LSTA manual and the detailing requirements of BS 6915. These documents define:

• Bay size limitations for Code 5 sheets.
• Correct lap sizing for gutters, cladding and roof coverings.
• Drip heights, falls and drainage requirements.
• Fixing and clipping methods suitable for heavy-gauge sheets.
• Thermal movement allowances and jointing requirements.

After installation, apply patination oil to achieve uniform weathering and minimise carbonate staining.

Installation essentials

1. Prepare substrates: Ensure smooth supporting surfaces and install
   Lead Underlay.
2. Cut into bays: Use BS 6915 limits for Code 5 sheet applications.
3. Fix appropriately: Use copper or stainless fixings from
   Leadwork Fixings.
4. Detail correctly: Form welts, steps, drips and upstands to LSTA guidance.
5. Finish neatly: Apply patination oil and verify junction integrity.
