Why choose Code 6 390mm 6m Roofing Lead?

Code 6 390mm 6m Roofing Lead is the dependable, heavier-gauge option when details need extra stiffness, longevity and smart presentation.
At approximately 2.65 mm thick and around 30.0 kg/m², it excels where lighter grades would feel under-spec:
deeper flashings, parapet/copings, compact bay panels and chimney aprons/back gutters. The 6 m length helps reduce the joint count versus 3 m rolls,
improving aesthetics and productivity wherever safe handling is planned. For technique refreshers and principle-led guidance, explore the articles at
The Lead Lads and our standards explainer:

Where Code 6 390mm 6m Roofing Lead fits best

• Wide/deeper flashings to brick or stone abutments and parapet upstands.
• Compact apron pieces & back gutters that benefit from a stiffer sheet.
• Parapet/coping weatherings and verge/eaves trims in higher exposure zones.
• Small bay roof panels (with sensible bay sizes, drips/rolls and a slip layer beneath).
• Refurbishment upgrades where moving from Code 3/4 to Code 6 increases service life.

Planning & set-out

Before cutting Code 6 390mm 6m Roofing Lead, confirm exposure, laps, bay sizes 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.

Installation essentials

1. Prepare the substrate: Provide a 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 390mm 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. Perimeter restraint: Where specified, use a Stainless Steel Fixing Strip and clips to manage wind uplift.
5. Finish & protect: Point chases (mortar or Lead Mate) and apply patination oil on visible work.

Choosing the right width

Code 6 390mm 6m Roofing Lead offers generous cover for flashings and compact weatherings. Step up to 450–600 mm for wider parapets or
drop to 300 mm where geometry allows. Matching width and code to function—plus thoughtful bay sizing, movement detailing and drainage—underpins long service life.
