Why choose Code 6 300mm 6m Roofing Lead?

Code 6 300mm 6m Roofing Lead is a heavier-gauge, narrow roll that’s ideal where you need robust flashings with crisp presentation.
At approximately 2.65 mm thick and ~30.0 kg/m², it adds stiffness and durability for
deep abutment flashings, chimney aprons/back gutters, verge/eaves trims and protective weatherings in exposed locations.
The 6 m length reduces joint count versus 3 m rolls, improving aesthetics and productivity where safe handling is planned.

Best-fit uses for Code 6 300mm 6m Roofing Lead

• Heavy-duty abutment flashings to brick/stone upstands where depth and stiffness are needed.
• Chimney aprons & back gutters that benefit from a stiffer sheet and clean arrises.
• Verge/eaves trims and protective weatherings in higher exposure zones.
• Small compact details where a narrow roll is easier to handle without excessive waste.
• Refurbishment upgrades stepping up from lighter codes for longer service life.

Planning & set-out

Confirm exposure, laps and joint positions before cutting Code 6 300mm 6m Roofing Lead. The 6 m format lowers joint count
but requires manual-handling planning (team lift, staging, edge protection). Align joints with drips/outlets, maintain clear drainage and avoid
trapping moisture. For project photos and finished install examples, see

Good practice with Code 6

Place mechanical fixings outside movement zones and never bridge expansion joints. Beneath wider weatherings and bays,
include a smooth slip layer to facilitate free movement and
reduce underside abrasion. Detail drips/rolls as appropriate to the exposure and geometry. Finish visible work with
Patination Oil to minimise early staining while the natural patina develops.
For chase restraint on adjacent flashings, use Hall Clips before pointing with mortar or
Lead Mate Sealant. Where perimeter edge restraint is specified, add a
Stainless Steel Fixing Strip and compatible clips to manage wind uplift.

Installation essentials

1. Prepare the substrate: Smooth, continuous bearing; remove sharp edges. Add a slip layer where required.
2. Set out & cut: Measure accurately and cut Code 6 300mm 6m Roofing Lead with clean edges for consistent laps.
3. Restraint & fixings: Use copper or stainless fixings/clips; keep them out of movement zones; avoid over-nailing.
4. Perimeter restraint: Use stainless fixing strip/clips where specified to resist wind uplift while allowing sliding.
5. Finish & protect: Point chases neatly (mortar or Lead Mate) and apply patination oil on visible work.

Choosing the right width

300 mm is a versatile flashing width. Step up to 390–510 mm for deeper flashings or compact weatherings, and 600–914 mm
for parapets and wider bays. Matching width and code to function—plus thoughtful movement detailing and drainage—underpins long service life. Revisit
