Lead Flashing – Code 3 – External Roofing

Product Overview

Our 40kg roll of high-performance milled lead flashing is designed for superior weatherproofing in a variety of applications. This roll offers a width of 450mm and a length of 6m, providing 2.7m² of coverage per roll. The Code 3 thickness of 1.32mm ensures that each square meter weighs 14.97kg, making it ideal for soakers, sheltered details, and lighter-duty weatherproofing where reduced weight and easier handling are required.

Features & Benefits

• Exceptional durability: Provides long service life with resistance to corrosion, UV exposure, and weathering.
• Malleability: Code 3 thickness offers easy dressing with hand tools for accurate formation of tight details.
• Weatherproofing: Creates an impermeable barrier preventing water penetration at roof junctions.
• BS EN 12588 compliance: Ensures consistent thickness and metallurgical quality.
• Sustainable material: Fully recyclable with high potential recycled content.

Applications

• Wide sheltered details: Suitable for protected parapet and junction work.
• Wide soakers: Ideal for large-format soaker fabrication.
• Dormer flashings: Perfect for broad dormer cheek intersections.
• Roof junctions: Appropriate for various small roof intersection details.

Installation Guidance

• Preparation: Ensure substrates are dry, sound, and free of debris.
• Fixing: Install with wedges or clips, allowing for thermal expansion.
• Lap joints: Provide a 100mm lap on pitches above 30°, increasing to 150mm for lower pitches or more exposed locations.
• Patination oil: Apply immediately after installation to prevent staining.
• Support: Provide adequate support beneath wider sections to reduce fatigue risk.

Manufactured to BS EN 12588, the milling process ensures uniform thickness, fine grain structure, and a smooth finish for consistent dressing and shaping during installation.
