Why choose Code 4 150mm 3m Roofing Lead?

Our code 4 150mm x 3m roofing lead is the perfect choice for everyday flashings, soakers and weathering details where additional strength is required over Code 3. At 150mm wide and supplied in a convenient 3m roll, it offers excellent handling, robust durability and a clean professional finish suitable for both domestic and commercial roofing applications.

Manufactured to BS EN 12588, this rolled lead gives predictable thickness across the full width, ensuring consistent performance on site. It dresses neatly into junctions and chases while providing the enhanced rigidity and life expectancy needed for exposed locations. For fast, accurate ordering, explore our interactive
Lead Flashing Calculator—ideal for tradespeople working on the move.

Typical uses for Code 4 150mm 3m Roofing Lead

• Stepped and straight flashings to brick or stone abutments.
• Individual soakers for tile and slate roof coverings.
• Small apron flashings and chimney detailing.
• Weathering to dormers, roof junctions and window heads.
• Heritage reinstatement requiring a traditional, durable finish.

Good practice with Code 4 150mm 3m Roofing Lead

As a narrow-width roll, code 4 150mm x 3m roofing lead is easy to dress into chases, over tiling and around junctions, but still requires correct detailing to ensure long-term performance. Keep lengths within sensible limits to avoid fatigue, and always use a suitable pointing material—either mortar or neutral cure sealant—for a neat finish. For more demanding weatherings or load-bearing applications, consider stepping up to wider or heavier codes from our
Rolled Lead range.
