Why choose code 5 1600mm 6m roofing lead?

The code 5 1600mm 6m roofing lead roll is one of the widest and heaviest standard rolled lead formats available. Designed for large-scale roof coverings, parapet weatherings, bay roofs and conservation-grade restoration work, this sheet delivers unmatched durability across major surface areas. At 1600mm wide and 6m long, it offers substantial coverage while maintaining the superior structural strength and long-term stability that Code 5 is known for.

Manufactured to BS EN 12588, this roll provides consistent thickness (approx. 2.24mm), excellent malleability and high resistance to corrosion. Roofing contractors choose code 5 1600mm 6m roofing lead for demanding applications where long-term reliability and exposure resistance are essential—particularly across heritage buildings, listed structures and major architectural detailing.

The extended 6m length minimises the number of joints required across large runs of weathering, improving performance and reducing potential failure points when installed in accordance with guidance and BS6915. When using rolled lead sheet, always adhere to the relevant standards and ensure appropriate fixing patters, bay sizing, drips, up stands, and interfaces.

Typical uses for code 5 1600mm 6m roofing lead

This ultra-wide roll is ideal for:

• Large bay roofs requiring heavy-duty coverings.
• Parapet cappings and boundary wall weatherings.
• Wide gutters, valleys and drainage channels.
• Heritage roofing and listed building reinstatement.
• Dormer tops, curved architectural detailing and stone cornices.
• Full-width weatherings where lighter gauges are insufficient.

Why Code 5 is essential for major coverings

Wider sheets experience proportionally greater thermal movement and surface loading, which is why code 5 1600mm 6m roofing lead is the material of choice for heavy-duty or heritage work. The increased gauge reduces fatigue cracking, enhances stability and significantly improves lifespan on exposed or structurally demanding installations.

Installation guidance

Due to its width and weight, this roll must be divided into correctly sized bays following LSTA/LSA recommendations. Install over an appropriate
lead underlay
to support movement and prevent underside corrosion.

After installation, apply patination oil to all exposed areas to achieve even weathering and reduce carbonate staining.

For chase jointing and perimeter seals, use mortar or
Lead Mate Sealant.

Installation essentials

1. Prepare the deck: Ensure full, rigid support and use underlay.
2. Set out bays: Include drips, welts and correct bay divisions.
3. Fix safely: Choose copper or stainless fixings from
   Leadwork Fixings.
4. Seal neatly: Use mortar or Lead Mate for clean joints.
5. Finish correctly: Apply patination oil immediately.
