Why choose code 6 180mm 6m roofing lead?

The code 6 180mm 6m roofing lead roll is a heavy-gauge, narrow-width sheet designed for high-exposure flashings, stepped flashings and abutment weatherings on demanding roof slopes. The increased stiffness of Code 6 provides outstanding fatigue resistance, making it the preferred choice for heritage roofing projects and exposed locations.

This size is commonly used on traditional roofs finished with durable slates such as
Welsh slates
and
Westmorland slates,
where additional rigidity and long-term performance are essential.

The longer 6m roll format is ideal for producing multiple identical stepped flashing pieces, helping installers work efficiently on large or repetitive abutment details.

Typical uses for code 6 180mm 6m roofing lead

• Stepped flashings for chimneys, parapets and heritage abutments.
• Cover flashings in high-exposure areas.
• Weatherproofing heavy slate roofs requiring long-life details.
• Abutment flashings where extra stiffness is required.
• Conservation roofing on listed structures and traditional buildings.

Code 6 for heritage & high-exposure flashings

Heritage slate roofs demand robust detailing. code 6 180mm 6m roofing lead delivers the mass and fatigue resistance required to withstand wind uplift, thermal movement and long-term weathering on exposed chimneys, parapets and roof junctions.

This format is widely specified by conservation architects and heritage roofing contractors working on churches, period homes and listed properties.

Installation essentials

1. Prepare the chase: Clean, consistent depth for stepped flashing insertion.
2. Cut repeated steps: Use the 6m roll for efficient batching of identical pieces.
3. Fix correctly: Use copper or stainless fixings from our
   Leadwork Fixings.
4. Dress neatly: Form flashings tight to slate surfaces with appropriate overlaps.
5. Finish the work: Apply patination oil to minimise early oxidation marks.
