Why choose Code 4 360mm 3m Roofing Lead?

The code 4 360mm x 3m roofing lead is an excellent choice when you need a wider flashing or weathering detail with the additional strength and rigidity of Code 4 thickness. At 360mm wide, this roll provides substantial coverage, reducing the number of laps and joints required on-site. It is ideal for chimney back gutters, large soakers, parapet weatherings, dormer tops and deeper abutment flashings where smaller widths would not offer sufficient protection.

Manufactured to BS EN 12588, every roll of code 4 360mm x 3m roofing lead benefits from consistent thickness and predictable performance across its width. This size is widely used across domestic, commercial and heritage roofing because it dresses cleanly into detail while providing excellent resistance to wind uplift, water penetration and long-term fatigue. For quick on-site ordering, our
Lead Flashing Calculator helps you select the correct width and code instantly.

Typical uses for Code 4 360mm 3m Roofing Lead

• Wide cover flashings on brick, stone or rendered abutments.
• Large slate or tile soakers where a bigger lap is required.
• Chimney back gutters, aprons and weathering details.
• Dormer tops, cheek weatherings and junction protection.
• Traditional and conservation roof reinstatement requiring wider rolled lead sheets.

Good practice with Code 4 360mm 3m Roofing Lead

Because code 4 360mm x 3m roofing lead provides wide coverage, correct movement control is essential. Always follow recognised guidance by limiting bay sizes, using welts and drips to shed water, and incorporating slip layers beneath the lead. Our
Lead Underlay collection provides suitable base materials to protect the underside and promote natural thermal movement. Correct detailing—especially in exposed areas—ensures long-term performance.
