Why choose code 5 240mm 3m roofing lead?

The code 5 240mm 3m roofing lead roll is a strong, versatile and heavy-gauge sheet ideal for exposed detailing, robust flashings, wide soakers and heritage reinstatement work. At 240mm wide, it provides more coverage than narrower strips while still remaining very manageable for installers working on chimneys, abutments and movement-heavy junctions that require long-term reliability.

Manufactured to BS EN 12588, this product offers predictable malleability, reliable shaping performance and enhanced corrosion resistance from its approximate 2.24mm thickness. Installers choose code 5 240mm 3m roofing lead for challenging details where lighter gauges may fatigue over time, particularly on chimneys exposed to high winds, high-movement abutments or premium architectural projects.

Its 3m roll length keeps the sheet lightweight enough to handle safely while significantly reducing the number of required joints—improving waterproofing and speeding up installation. This makes it an excellent all-round size for roofing professionals who need durability, coverage and workability in one roll.

Thanks to its width and enhanced strength, this roll is commonly used for:

• Chimney flashings on brick or stone abutments.

Why choose Code 5 for wider roofing details?

When the detail requires better stability, strength and resistance to fatigue, code 5 240mm 3m roofing lead provides a dependable upgrade. The increased thickness reduces the risk of cracking in high-stress areas, improves lifespan and maximises resilience in locations where thermal expansion is frequent.

• Superior performance in exposed or wind-prone areas.
• Significantly reduced fatigue risk compared with Code 3 or 4.
• Ideal for chimneys and abutments with thermal expansion cycles.
• Extended lifespan on heritage and premium installations.

Installation guidance
