Lead Flashing | Roofing Supplies

Lead flashing is one of the most reliable materials for preventing water ingress around chimneys, walls, roof junctions and pitched or flat roof details. Known for its exceptional lifespan, flexibility and weather resistance, lead flashing ensures a secure, watertight seal that lasts for decades. It is widely used across residential, commercial and heritage buildings due to its proven performance.

Lead Rolls for Long-Lasting Roof and Chimney Seals

Our lead rolls offer outstanding durability and are available in a range of codes suitable for pitched roofs, flat roofs, valleys, dormers and chimney work. Lead rolls are easy to shape, flexible enough to mould around complex details and strong enough to withstand extreme weather conditions. Their natural corrosion resistance makes them ideal for long-term waterproofing solutions.

Lead Accessories for Safe, Secure and Professional Installation

A wide selection of lead accessories is available to ensure your installation is safe, efficient and long-lasting. From patination oil and fixings to sealants, clips, tools and expansion joints, these accessories help prevent staining, improve bonding and ensure the lead sits securely in place. Lead accessories are essential for achieving a clean, professional finish that resists movement and weathering.

Lead Flashing for Superior Waterproofing and Structural Protection

Lead flashing provides unbeatable performance when installed around vulnerable roof details such as chimneys, abutments, skylights and parapet walls. Its flexibility allows it to be dressed neatly into brickwork or roofing materials, delivering a watertight barrier that prevents leaks and protects internal structures. Known for its sustainability and recyclability, lead flashing remains the industry standard for premium roof waterproofing.

Long-Term Durability and Weather Resistance

Thanks to its natural resilience, lead requires minimal maintenance and is capable of lasting well over 50 years. Its ability to expand and contract without cracking makes lead flashing ideal for the UK climate.

Suitable for New Builds, Repairs and Heritage Projects

Whether you’re working on a modern extension, a complete reroof or a listed building, lead products adapt easily to different architectural styles while providing excellent protection.
