Why choose Code 3 240mm 6m Roofing Lead?

The code 3 240mm x 6m roofing lead roll is a highly versatile choice for small-to-medium roof flashings, soakers, abutment weatherings and chimney detailing. Its 240mm width provides more coverage than 180–210mm rolls while still maintaining the lightweight, easy-to-handle characteristics that make Code 3 ideal for fine leadwork.

Manufactured to BS EN 12588, the code 3 240mm x 6m roofing lead offers consistent thickness and predictable movement behaviour, ensuring durable performance across both traditional and modern roofing applications. Because Code 3 is lighter than Code 4 and 5, it is perfect for smaller flashings and weatherings where flexibility and fast shaping are essential.

The long 6m roll is ideal for installers looking to reduce joints and overlaps. Fewer seams mean better waterproofing and a cleaner appearance—especially useful around dormers, long chimney skirts and extended abutment junctions.

Typical uses for Code 3 240mm 6m Roofing Lead

The code 3 240mm x 6m roofing lead is ideal for installers who require a medium-width roll suitable for general-purpose roof leadwork, including:

Why the 6m roll is a major benefit

One of the strongest advantages of the code 3 240mm x 6m roofing lead is the long roll format. By reducing the number of laps, fixings and cuts, installers benefit from a quicker workflow and improved long-term performance.

• Fewer joints improve weather resistance.
• Fast installation thanks to longer continuous lengths.
• Cleaner visual finish around chimneys and dormers.
• Less waste when covering medium-length runs.
• Enhanced efficiency on refurbishment and new-build projects.

Installation guidance & best practice

Although Code 3 is lightweight and simple to work with, it must be installed correctly to ensure lasting performance. Follow BS EN 12588 and LSTA/LSA guidelines for flashing design, correct lap formation and fixing methods.

Avoid overstretching the sheet when dressing into deep chases or complex profiles. All exposed leadwork should be protected immediately after installation with patination oil to prevent early staining.

For chase sealing, use mortar or
Lead Mate Sealant.
