Why choose code 5 360mm 3m roofing lead?

The code 5 360mm 3m roofing lead roll is designed for roofing professionals who require wide, heavy-duty lead capable of handling demanding detailing conditions. At 360mm wide, this roll offers substantial coverage for robust weatherings, wide flashings, chimney aprons, roof junctions and heritage-grade work where a strong, long-life material is essential.

With an approximate thickness of 2.24mm and manufactured to the BS EN 12588 standard, this roll provides dependable structural strength, predictable shaping behaviour and excellent resistance to corrosion. Installers choose code 5 360mm 3m roofing lead for demanding applications where Code 3 or Code 4 would not provide sufficient longevity—particularly on exposed chimneys, parapets and wide abutments.

The manageable 3m roll length keeps weight under control while reducing joint frequency, ensuring cleaner detailing and improved waterproofing across wide flashings and weatherings.

Typical uses for code 5 360mm 3m roofing lead

Thanks to its wide format and structural resilience, this roll is ideal for:

• Chimney aprons and back gutters requiring generous coverage.
• Wide cover flashings on pitched or flat roof abutments.
• Weatherings to parapets, dormer roofs and low-pitch surfaces.
• Large-format soakers for slate and tile roofing.
• Heritage restoration work requiring Code 5 specification.
• Replacement of wide flashings where lighter gauges have failed.

Why Code 5 is ideal for wider flashings

Wider rolls experience more thermal movement and greater loading than narrow strips, which is why code 5 360mm 3m roofing lead is often specified for high-exposure areas. The increased gauge reduces the risk of fatigue cracking and enhances stability on details where wind uplift or prolonged water run-off are common.

• Superior rigidity in exposed environments.
• Improved fatigue resistance compared with lighter codes.
• Excellent shaping performance without compromising strength.
• Suitable for all traditional and conservation-grade detailing.

Installation guidance

Code 5 must always be installed in accordance with BS EN 12588 and LSTA/LSA technical guidelines. Proper chase preparation, fixing distances and movement allowances are critical to ensuring long-term serviceability.

After installation, all exposed surfaces of code 5 360mm 3m roofing lead should be coated with patination oil to reduce surface staining and promote even weathering.

Seal chases neatly using traditional mortar or
Lead Mate Sealant.

Installation essentials

1. Prepare chases: Ensure clean, consistent depth and width.
2. Dress the sheet: Avoid overstretching the gauge.
3. Fix correctly: Use copper or stainless fixings from
   Leadwork Fixings.
4. Seal joints neatly: Use mortar or Lead Mate.
5. Apply patination oil: Protect all exposed leadwork.
