Lead Flashing – Code 3 – Exterior Roofing

Product Overview

This Heavy Duty Roll of Milled Lead Flashing weighs 30kg and measures 390mm in width and 3m in length, providing approximately 1.17m² of coverage per roll. The Code 5 lead flashing features a nominal thickness of 2.24mm, equating to 25.4kg per m², making it suitable for wider applications exposed to wind uplift or thermal movement.

Its 390mm width is optimal for long aprons, step flashings, parapet weatherings, and chimney detailing. The 3m roll is easy to handle, perfect for patch repairs, smaller projects, or areas with restricted access. Manufactured to BS EN 12588 standards, it ensures uniform thickness, fine grain structure, and a smooth finish.

This lead flashing provides a malleable, durable, and waterproof seal at critical junctions such as abutments, chimneys, and parapets, preventing water ingress and extending building fabric lifespan. Application of patination oil after installation is recommended to prevent staining.
