Why choose code 5 914mm 6m roofing lead?

The code 5 914mm 6m roofing lead roll is a wide, heavy-gauge sheet designed for bay roofs, parapet weatherings, wide gutters and structural coverings where long-term protection is essential. At 914mm wide and 6m long, it offers substantial coverage per roll while delivering the strength, rigidity and service life associated with Code 5 rolled lead.

Manufactured to BS EN 12588, this sheet provides consistent thickness (approx. 2.24mm), predictable behaviour during forming and excellent resistance to fatigue cracking. The code 5 914mm 6m roofing lead format is regularly specified on high-value domestic projects, heritage roofs and commercial schemes where the lead is acting as a primary covering rather than a small flashing.

The 6m length reduces the number of joints along parapets, bays and gutter runs, supporting better watertightness and visual consistency when detailed and fixed correctly in accordance with LSTA/LSA guidance.

Typical uses for code 5 914mm 6m roofing lead

This wide roll format is chosen where the sheet forms a key weathering surface. Common applications include:

• Bay roof coverings on dormers and projecting windows.
• Parapet and boundary wall cappings where wide coverage is needed.
• Wide gutters, sumps and drainage channels on traditional roofs.
• Weatherings to stone cornices, string courses and architectural ledges.
• Lead trays and structural weatherings on heritage or listed buildings.
• Upgrading older coverings that have failed due to underspecified gauges.

Design considerations for 914mm-wide Code 5 sheets

With code 5 914mm 6m roofing lead, correct bay setting-out is critical. Wider sheets experience more thermal movement and loading, so they must be divided into appropriate bays with drips, welts and joints sized to suit Code 5 performance limits.

• Divide large coverings into bays sized in line with LSTA/LSA guidance for Code 5.
• Use drips and falls to move water away and prevent ponding on flat or low-pitch areas.
• Install over a suitable underlay from our
  Lead Underlay range to protect the underside and allow controlled movement.
• Detail junctions to accommodate structural and thermal movement in the substrate.
• Provide safe access routes if limited foot traffic is anticipated for maintenance.

Installation guidance for this 914mm 6m Code 5 roll

Extra-wide heavy-gauge sheets should always be installed following BS EN 12588 workmanship principles and recognised LSTA/LSA detailing. This includes ensuring full support, correct fixing patterns and carefully formed drips, welts and laps.

Once installed, code 5 914mm 6m roofing lead should be treated with patination oil to control early carbonate staining and promote even surface weathering.

For chase sealing, perimeters and terminations into masonry, use mortar or
Lead Mate Sealant
as appropriate to the detail and exposure.

Installation essentials

1. Prepare the deck or parapet: Provide a smooth, fully supported base and install suitable lead underlay.
2. Set out bays: Divide coverings into appropriate bay lengths and widths for Code 5 movement limits.
3. Fix and clip: Use copper or stainless fixings from our
   Leadwork Fixings range, positioned to allow expansion and contraction.
4. Form joints and drips: Use welts, laps and drips in line with LSTA/LSA details.
5. Finish and protect: Seal joints, then apply patination oil to all exposed lead surfaces.
