Lead Flashing
Formed lead flashing used to seal and protect roof and wall penetrations, designed to support long-term weather protection in construction and roofing systems.
Key Features and Benefits
Malleable lead sheet construction – allows flashing to be shaped tightly around roof penetrations and building joints
Continuous flashing profiles – create durable water barriers along roof edges, chimneys, and wall intersections
Dense metal composition – resists cracking and deformation during installation and long-term exposure
Flexible forming capability – adapts to uneven masonry, roofing materials, and structural surfaces
Durable weather-resistant material – maintains performance under prolonged exposure to rain, snow, and temperature changes
Compatibility with masonry and roofing assemblies – supports integration with brickwork, roofing membranes, and structural flashing systems
Product Overview
Lead flashing is used in building construction to seal joints, penetrations, and transitions where water intrusion could occur. Installed at critical points such as roof edges, chimneys, vents, and wall intersections, flashing forms a physical barrier that directs water away from vulnerable building structures.
The malleable nature of lead allows installers to shape flashing around irregular surfaces, masonry joints, and roofing materials while maintaining continuous coverage. This flexibility helps create durable seals that remain effective even as building materials expand and contract with temperature changes.
Our lead flashing products are manufactured from formed lead sheets designed for integration into roofing and wall assemblies. These flashing components are typically installed as part of a broader building envelope strategy that includes roofing membranes, drainage systems, and structural weatherproofing elements to support long-term moisture protection.
