Why choose Code 6 360mm 3m Roofing Lead?

Code 6 360mm 3m Roofing Lead is a heavy-duty roll for flashings and compact weatherings where you need added stiffness and a clean, long-lasting finish,
but you don’t want an overly wide sheet. At approximately 2.65 mm thickness and around 30.0 kg/m², Code 6 is
ideal where lighter grades can distort, fatigue, or end up over-fixed in an attempt to keep them flat.

The 360 mm width gives extra cover compared with 300 mm while remaining easy to handle on scaffolds and in tight access zones. The
3 m length supports sensible piece lengths for movement control and controlled dressing—particularly useful for chimney aprons, deeper abutment flashings,
and compact protective weatherings. For principle-led guidance on movement zones and restraint strategy, see

Best-fit uses for Code 6 360mm 3m Roofing Lead

• Deeper abutment flashings to brick/stone upstands and parapet returns.
• Chimney aprons & back gutter interfaces where stiffness improves shape retention.
• Compact weatherings to upstands, dormer details and junctions needing extra cover.
• Protective trims in higher exposure zones where light sheet can flutter or fatigue.
• Refurbishment upgrades replacing distorted or over-nailed lighter lead.

Planning & set-out

Before cutting Code 6 360mm 3m Roofing Lead, confirm lap requirements, joint positions and where any drips/turns will fall. Keep piece lengths sensible for
movement control and avoid “dead pockets” that trap water and debris. Where flashings are chased into masonry, set the chase depth and line first to avoid dressing lead
unnecessarily and to maintain a clean finish.

Good practice: movement, slip layers and restraint

Lead moves—so detailing must allow for it. Keep mechanical fixings out of movement zones and never bridge expansion features. Under wider weatherings and bay elements,
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 associated with the detail, use Hall Clips for chase restraint, then point neatly with mortar or
Lead Mate Sealant depending on the specification. For a cleaner early-life finish 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 correct restraint with movement-friendly detailing and keep fixings out of movement zones.
5. Finish: Check drainage, keep outlets clear, and protect adjacent finishes during dressing and welding/burning (if applicable).

Choosing the right width

360 mm offers extra cover over 300 mm without moving into very wide sheet territory. If you need more cover, move to 390–450–510 mm for deeper flashings or compact weatherings;
for parapets and bay panels, consider 600 mm+. Matching width and code to function—plus thoughtful movement detailing and drainage—underpins long service life.
