Why choose Code 6 760mm 3m Roofing Lead?

Code 6 760mm 3m Roofing Lead is a wide, heavy-duty roll for details that need stiffness, longevity and a clean finish without the handling demands of 6 m rolls.
At approximately 2.65 mm thick and around 30.0 kg/m², Code 6 is commonly specified for
parapet and coping weatherings, compact bay roof panels, chimney aprons/back gutters and wide protective flashings in exposed locations.
The 3 m length is easier to manoeuvre on scaffolds and tight access zones, and it helps keep piece lengths sensible for movement control.

Best-fit uses for Code 6 760mm

• Parapet/coping weatherings where broad cover and crisp drips are required.
• Compact bay roof panels with sensible bay sizes, drips/rolls and a slip layer beneath.
• Chimney aprons, back gutters & saddles benefiting from extra stiffness and coverage.
• Wide/deeper flashings to upstands and abutments in higher exposure zones.
• Refurbishment upgrades where lighter lead has fatigued, buckled or been over-fixed.

Planning & set-out

Before cutting Code 6 760mm 3m Roofing Lead, confirm lap requirements, joint positions and where drips/rolls will fall.
The 3 m format offers excellent control on awkward scaffolds and makes it easier to avoid over-length pieces that cannot move freely.
Maintain clear drainage paths, avoid “dead pockets”, and protect adjacent finishes during dressing. For finished examples of leadwork quality and detailing,

Good practice: movement, slip layers and restraint

Lead moves — so your detailing must allow for it. Keep mechanical fixings out of movement zones and never bridge expansion features.
Under bays and broad weatherings, use a smooth Building Paper Lead Underlay (slip layer)
to reduce underside abrasion and help the sheet slide rather than buckle. Where perimeter edges are exposed to wind uplift, use a
Stainless Steel Fixing Strip and compatible clips to restrain the edge while allowing controlled movement.

For chase flashings, use Hall Clips for chase restraint, then point neatly with mortar or
Lead Mate Sealant depending on the specification. For early-life presentation and reduced staining on visible elevations,
apply Lead Patination Oil.

Installation essentials

1. Substrate preparation: Ensure smooth, continuous bearing and remove sharp arrises that can puncture lead.
2. Cut and dress: Cut cleanly and dress with the right tools to form crisp drips, turns and welts without over-stretching.
3. Fixings: Use Copper ARS Nails or
   Stainless Ringshank Nails where specified; avoid over-fixing.
4. Restraint strategy: Combine perimeter restraint (where required) with movement-friendly detailing and keep fixings out of movement zones.
5. Finish: Seal chases neatly, check drainage, and apply patination oil for a cleaner early-life appearance.

Choosing the right width

760 mm offers substantial cover for parapets and compact bays. Step up to 800–850–914 mm where very wide weatherings are required,
or drop to 600 mm where geometry and handling dictate. Matching width and code to function — plus thoughtful bay sizing, movement detailing and drainage —
underpins long service life. Revisit principle-led guidance aligned with recognised practice at
