Why choose Code 6 850mm 6m Roofing Lead?

Code 6 850mm 6m Roofing Lead is a wide, heavy-duty roll designed for parapet/coping weatherings, compact bay roof panels, chimney aprons/back gutters
and other high-exposure details where stiffness and service life matter. At roughly 2.65 mm thick and ~30.0 kg/m², it provides a robust
covering that still dresses cleanly with the right tools and technique. The 6 m length helps reduce joint count compared with 3 m rolls, improving presentation and
speeding installation where access allows safe handling. For principle-led refreshers on bay sizing, movement control and sequencing, explore

Best-fit uses for Code 6 850mm 6m Roofing Lead

• Parapet/coping weatherings and wide cappings where deeper laps and fewer joints are preferred.
• Compact bay roof panels (with sensible bay sizes, drips/rolls and a slip layer to manage movement).
• Chimney aprons, back gutters and saddles that benefit from added stiffness and broader coverage.
• Dormer tops/cheeks and larger upstands requiring robust weathering and a crisp finish.
• Refurbishment upgrades where stepping up from lighter codes improves longevity in exposed locations.

Planning & set-out

Before cutting Code 6 850mm 6m Roofing Lead, confirm exposure, laps, bay sizes and joint positions. Keep single-piece lengths sensible for the detail and site access;
while 6 m reduces joints, manual handling must be planned (team lift, edge protection, safe staging). Align joints with drips/outlets and maintain clear drainage paths.

Good practice with Code 6

Use mechanical fixings sparingly and outside movement zones. Under 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 prior to pointing with mortar or
Lead Mate Sealant.

Installation essentials

1. Prepare the substrate: Smooth, continuous bearing; remove sharp edges. Add a slip layer beneath bays and wide coverings.
2. Set out & cut: Measure accurately and cut Code 6 850mm 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: Where specified, use a Stainless Steel Fixing Strip and clips to manage wind uplift.
5. Finish & protect: Point chases neatly (mortar or Lead Mate) and apply patination oil on visible work.

Choosing the right code & width

Select Code 6 when the lead sheet acts as a covering (bays/parapets) or where detail depth and exposure exceed the comfort zone of lighter grades.
The 850 mm width offers generous coverage across parapets and compact bays; step down to 600–750 mm where geometry or handling dictates,
or step up to wider sheets only if design allows correct bay sizing and movement control. Matching code and width to function is central to long service life.
