Why choose code 5 180mm 3m roofing lead?

The code 5 180mm 3m roofing lead roll is a heavy-duty narrow-width sheet designed for exposed work, high-load detailing and long-life flashings. At 180mm wide, it offers the perfect balance between rigidity, durability and easy handling, making it an excellent choice for premium roofing and heritage projects where Code 3 and Code 4 do not provide sufficient strength.

Manufactured to BS EN 12588, this roll offers uniform thickness (approx. 2.24mm), reliable malleability and excellent corrosion resistance. Installers select code 5 180mm 3m roofing lead for chimney flashings, soakers, narrow aprons, exposed abutments and weatherings requiring enhanced long-term performance.

Its manageable 3m length keeps weight under control while delivering efficient coverage with fewer joints and cleaner visual lines on site.

Typical uses for code 5 180mm 3m roofing lead

This roll is commonly chosen for:

• Strong stepped flashings to chimneys and abutments.
• Narrow soakers on slate or tile roofs exposed to wind uplift.
• Small but critical weatherings needing high durability.
• Reinstatement work to heritage buildings requiring Code 5.
• Skirtings, cover flashings and tight-profile detailing.

Why choose Code 5 for narrow flashings?

When long-term reliability matters, code 5 180mm 3m roofing lead provides superior resistance to fatigue, cracking and movement. The additional thickness helps protect high-stress details, especially where thermal expansion or wind uplift is a concern.

• Higher resistance to wind and weather exposure.
• Ideal for abutments subject to regular thermal movement.
• Excellent malleability while maintaining structural strength.
• Longer lifespan than lighter gauges.

Installation guidance

Code 5 must always be installed to LSTA/LSA standards and BS EN 12588 guidance. Correct fixings, chase depths and movement allowances are essential to ensure durability.

After fitting, treat the installed code 5 180mm 3m roofing lead with patination oil to improve weathering and reduce surface staining.

For sealing chases and detailing edges, use mortar or
Lead Mate Sealant.
