Why choose Code 6 800mm 3m Roofing Lead?

Code 6 800mm 3m Roofing Lead is a wide, heavy-duty roll used where you need generous cover, strong drips and a crisp, long-lasting finish:
parapet/coping weatherings, wide bay roof panels, and exposed junctions that demand extra stiffness. At approximately
2.65 mm thickness and around 30.0 kg/m², Code 6 is designed to perform as a covering
rather than a light flashing—ideal when durability, appearance and movement control all matter.

The 800 mm width provides substantial coverage for wider parapets and bay layouts without stitching multiple narrow sheets together,
while the 3 m length keeps handling more controlled on scaffolds and awkward access. This size is often chosen when 760 mm is close,
but you want extra cover to form turns and drips with confidence and keep lap allowances comfortable.

Best-fit uses for Code 6 800mm 3m Roofing Lead

• Parapet/coping weatherings and wide cappings with deep laps and crisp drips.
• Wide bay roof panels with sensible bay sizes, drips/rolls and a slip layer beneath.
• Wide upstands and junctions where extra cover reduces joints and improves presentation.
• Chimney aprons & back gutters where depth and stiffness improve longevity.
• Refurbishment upgrades where lighter lead has fatigued, buckled, or been over-fixed.

Planning & set-out

Before cutting Code 6 800mm 3m Roofing Lead, confirm lap requirements, joint positions and where drips/rolls will fall. Keep piece lengths sensible for
movement control and avoid “dead pockets” that trap water and debris. The 3 m format makes it easier to control panel lengths and detailing in tight access zones.

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 bays and broad weatherings,
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 perimeter restraint (where required) 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

800 mm offers substantial cover for wide parapets and bay formation without joining multiple narrower sheets. If geometry or handling is tight, 760 mm may be a better fit.
If you need maximum cover, consider 850–914 mm widths; if the detail is a narrower flashing rather than a covering, step down to 390–600 mm widths.
Matching width and code to function—plus thoughtful bay sizing, movement detailing and drainage—underpins long service life.
