Code 5 Lead Roll

Code 5 Lead Roll is a high-quality, durable material designed for demanding roofing and flashing applications where weather resistance and flexibility are essential. Manufactured to British Standard BS EN12588, this rolled lead sheet is a top performer in both residential and commercial builds. It offers excellent coverage and is especially well-suited to areas where water ingress is a concern—such as chimney bases, roof tile abutments, and junctions between roofing and brickwork. What sets Code 5 apart is its increased thickness compared to lower codes, giving it even more resilience and a longer lifespan—perfect for heritage restoration or exposed locations where maximum protection is key.

Environmentally Friendly & Built to Last

As a part of the Enviro Lead range, Code 5 lead sheet is 100% recyclable and offers outstanding sustainability credentials. It has been awarded BRE Green Guide ratings of A and A+, making it one of the most eco-conscious choices in the roofing industry. Not only does it offer long-term performance, but it also supports greener building practices. Lead has been used for centuries, and its unmatched ability to conform to complex shapes and withstand the test of time makes it a reliable favourite among professional roofers and builders. With proper installation, it can last well over 50 years with minimal maintenance.

Ideal Applications for Code 5 Lead

• Thanks to its increased thickness, Code 5 lead is ideal for areas exposed to extreme weather conditions or where a longer strip of flashing is needed. It's commonly used around chimney stacks, wall abutments, dormer roofs, parapet walls, and valleys—anywhere with a high risk of water penetration. It can also be shaped easily around tiles and contours, forming a watertight seal where other materials may struggle.
• Whether you’re working on a listed building, a contemporary home, or a commercial site, Code 5 lead provides the confidence and quality needed for superior protection.

Roof Tiles & Fittings:

We recommend ordering an additional 10% of roof tiles to allow for any breakages that may occur during delivery or handling. Roof tiles are naturally fragile, and having a few extra on site helps prevent delays and ensures your roofing project can be completed without interruption.
