Why choose the Premium Code 4 800mm 6m Roofing Lead?

The code 4 800mm x 6m roofing lead is one of the widest and most heavy-duty long-length rolls available in the UK market.

Good practice when installing 800mm lead

At 800mm wide, this sheet must be installed on a fully supported surface, with proper movement joints and correct fixing intervals following LSTA/LSA guidelines. Take care not to overstretch during dressing, especially over large areas.

Patination oil should be applied immediately after installation to minimise staining and promote even weathering. Seal chases with mortar or
Lead Mate Sealant for a crisp, durable finish.

Installation essentials

1. Support the sheet fully: Ensure continuous backing beneath the full 800mm width.
2. Shape & cut precisely: Dress the code 4 800mm x 6m roofing lead carefully to avoid stretch marks.
3. Fix with suitable nails: Choose copper or stainless fixings from our
   fixings range.
4. Seal the chase: Use mortar or Lead Mate Sealant.
5. Protect the finish: Apply patination oil across the entire surface.
