Why choose Code 6 210mm 3m Roofing Lead?

Code 6 210mm 3m Roofing Lead is a narrow roll in a heavier gauge, designed for flashings and trims where space is constrained but you still want
stiffness, durability and a tidy finish. At approximately 2.65 mm thickness and around 30.0 kg/m², Code 6 holds a clean line once dressed
and is a strong choice in exposed locations where light sheet can distort, fatigue, or end up over-fixed.

The 210 mm width suits compact junctions and chases—ideal when masonry geometry or adjacent roof coverings limit how wide a flashing can be.
The 3 m length is easy to handle on scaffolds and supports sensible piece lengths for movement control and controlled dressing.

Best-fit uses for Code 6 210mm 3m Roofing Lead

• Narrow abutment flashings to brick/stone where robustness matters.
• Compact stepped/cover flashings in chases where width is limited but stiffness is beneficial.
• Small trims & protective weatherings at eaves/verges and upstands.
• Chimney details where a stiffer sheet helps maintain shape and finish.
• Refurbishment upgrades where lighter lead has distorted or fatigued.

Planning & set-out

Before cutting Code 6 210mm 3m Roofing Lead, confirm lap requirements, chase depth (where relevant) and joint positions. Keep piece lengths sensible for movement control,
align joints with steps and drips, and avoid “dead pockets” that trap water and debris. A clean set-out makes it easier to dress the lead neatly and achieve a consistent finished edge.

Good practice: movement, restraint and finishing

Lead moves—so detailing must allow for it. Keep mechanical fixings out of movement zones and never bridge expansion features. For chase restraint, use
Hall Clips then point neatly with mortar or
Lead Mate Sealant depending on the specification. Where a slip layer is appropriate beneath wider weatherings,
use Building Paper Lead Underlay to reduce underside abrasion and help the sheet slide rather than buckle.
For a cleaner early-life finish on visible elevations, apply Lead Patination Oil.

Installation essentials

1. Substrate preparation: Ensure smooth bearing surfaces and remove sharp arrises that can puncture lead.
2. Cut and dress: Cut cleanly and dress with the right tools to form crisp arrises without over-stretching.
3. Fixings: Use Copper ARS Nails or
   Stainless Ringshank Nails where specified; avoid over-fixing.
4. Restraint: Use Hall Clips in chases and keep fixings out of movement zones to prevent fatigue and splitting.
5. Finish: Check drainage and seal chases neatly; protect adjacent finishes during dressing and pointing.

Choosing the right width

210 mm is ideal where space is tight and you need a narrow flashing. If you need more cover, move to 240–300 mm for deeper flashings, or 360–390 mm where geometry allows.
Matching width and code to function—plus thoughtful movement detailing and drainage—underpins long service life.
