Why choose code 6 1600mm 6m roofing lead?

The code 6 1600mm 6m roofing lead roll is one of the widest and most substantial heavy-duty lead sheets available. At 1600mm wide and supplied in a generous 6m length, it is designed for large gutters, extensive lead roof coverings and major heritage roofing applications where exceptional durability is essential.

Code 6 delivers superior stiffness and fatigue resistance, making it ideal for long-life traditional roofing, including churches, listed buildings, civic structures and historic properties. This format is typically used where the lead forms a primary waterproofing layer, not simply a flashing.
