Why choose Code 6 600mm 6m Roofing Lead?

Code 6 600mm 6m Roofing Lead delivers a sweet spot of width and stiffness for demanding details that need durability and an immaculate finish.
At approximately 2.65 mm thick and around 30.0 kg/m², Code 6 is the right choice for
deeper flashings, parapet/copings, compact bay roof panels and chimney aprons/back gutters where lighter grades would be under-spec.
The 6 m length helps reduce joint count versus 3 m rolls, improving presentation and productivity where safe handling is planned.

Best-fit uses

• Parapet/coping weatherings where broader cover and fewer joints are preferred.
• Wide/deeper flashings to brick/stone abutments and upstands in exposed locations.
• Compact bay roof panels (with sensible bay sizes, drips/rolls and a slip layer beneath).
• Chimney aprons & back gutters benefitting from added stiffness and generous width.
• Refurbishment upgrades stepping up from Code 3/4 for increased service life.

Planning & set-out

Before cutting Code 6 600mm 6m Roofing Lead, confirm exposure, laps and joint positions. The 6 m format reduces joints,
but plan manual handling (team lift, safe staging, edge protection). Align joints with drips/outlets, keep drainage paths clear and avoid trapping moisture.

Good practice with Code 6

Use mechanical fixings sparingly and outside movement zones; never bridge expansion joints. Beneath bay panels and wider weatherings,
include a smooth slip layer to facilitate free expansion/contraction and reduce underside abrasion.
Detail drips/rolls or expansion features appropriate to bay size and exposure. Finish visible elevations with
Patination Oil to minimise early staining while the natural patina develops.
For chase restraint on adjacent flashings use Hall Clips, then point neatly with mortar or
Lead Mate Sealant. Where perimeter edge restraint is specified, add a
Stainless Steel Fixing Strip and clips to manage wind uplift.

Installation essentials

1. Prepare the substrate: Smooth, continuous bearing; remove sharp edges. Add a slip layer under bays and wide coverings.
2. Set out & cut: Measure accurately and cut Code 6 600mm 6m Roofing Lead with clean edges for consistent laps and crisp arrises.
3. Restraint & fixings: Use copper or stainless fixings/clips; position out of movement zones and avoid over-nailing.
4. Edge/perimeter restraint: Use stainless fixing strips/clips where specified to resist wind uplift while allowing sliding movement.
5. Finish & protect: Point chases (mortar or Lead Mate) and apply patination oil on visible work.

Choosing the right width

600 mm offers generous cover for parapets and compact bays. Step up to 750–850–914 mm for very wide weatherings or
drop to 450–510 mm where geometry allows. 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
