Why choose code 6 1600mm 3m roofing lead?

The code 6 1600mm 3m roofing lead roll is one of the widest heavy-duty lead formats used in traditional roofing. At 1600mm wide, it is specifically selected for large lead gutters, bigger lead roof areas and major heritage applications where longevity, strength and fatigue resistance are critical. Code 6 provides the mass and stiffness needed for demanding flat and low-pitch work, particularly on historic and high-value buildings.

This extra-wide sheet is ideal where the lead forms a primary waterproof covering rather than a simple flashing. Typical uses include parapet and boundary gutters, wide valley and parapet gutters, large bays laid over timber decks and complex junctions on traditional roofs. The 3m length keeps each unit manageable for handling and installation while still offering generous coverage.

Typical uses for code 6 1600mm 3m roofing lead

This heavy-gauge, extra-wide sheet is chosen for large-scale and high-value details, including:

• Large lead gutters, parapet gutters and boundary gutters on heritage roofs.
• Wide lead roof areas on flat and low-pitch structures where Code 6 is specified.
• Lead bays formed over King Rolls on traditional and historic buildings.
• Heavy heritage roofing applications where long service life is a key requirement.
• Major junctions, sumps and drainage details handling high water volumes.

Code 6 1600mm 3m roofing lead for large lead roofs & heritage work

On long-life traditional roofs – particularly those finished with Welsh or Westmorland slate – wide lead gutters and lead roof coverings must match the durability of the main covering. Code 6 1600mm 3m roofing lead provides the mass, stiffness and fatigue resistance demanded by conservation architects, heritage roofing specialists and surveyors on churches, listed properties and landmark buildings.

When used with properly set-out bays, correctly spaced King Rolls and compliant laps, Code 6 can deliver decades of reliable service in exposed coastal or upland environments, helping to protect both the building fabric and its interior finishes.

Installation guidance

While BS EN 12588 defines the material standard for rolled lead sheet, the design and workmanship requirements for installing code 6 1600mm 3m roofing lead are set out in:

• BS 6915 — Design & installation of lead sheet roof and wall coverings.
• LSTA Lead Sheet Manual — Practical detailing and site guidance.

These sources define maximum bay sizes, drip details, laps, fixings and expansion arrangements for Code 6 lead, which are particularly important when working with large lead gutters and wide roof areas.

Installation essentials

1. Prepare the deck: Provide a smooth, ventilated timber substrate and install
   Lead Underlay beneath all bays.
2. Set out bays & King Rolls: Divide large areas of code 6 1600mm 3m roofing lead into compliant bays, using
   King Rolls to form welts and manage movement.
3. Fix and clip correctly: Use
   copper roof strips
   and
   copper leadwork nails 3.35 × 25mm,
   or alternative copper/stainless fixings from our
   Leadwork Fixings range.
4. Detail drips & laps: Form drips, welts and laps strictly in accordance with BS 6915 and LSTA recommendations for Code 6 lead.
5. Finish the surface: Apply patination oil from our
   Accessories range to all new work to control early weathering and staining.
