What Is Roof Lead Flashing?
Roof lead flashing is a flexible sheet metal that bridges and seals gaps between roof surfaces and adjoining walls or features. It prevents water from penetrating the structure, ensuring weatherproof performance even in exposed conditions. Milled lead is the most common type, which is produced to strict tolerances. Cast lead, while heavier and less common, is sometimes used for heritage restoration work.
Benefits of Using Roof Lead
Lead’s natural flexibility makes it easy to shape and dress to contours. It resists corrosion, UV damage, and extreme temperature changes, hence why it is so popular in the UK's inconsistent climate. Lead is 100% recyclable and can be reused multiple times without losing performance.
Lead Flashing Codes and Sizes
Lead codes indicate the sheet’s thickness and weight, with each suited to specific applications. Code 3 is commonly used for soakers, Code 4 for step and cover flashings, and heavier grades like Code 5 or 6 for gutters, valleys, and flat roof work. We hold stock in both 3m and 6m roll lengths to suit different installation requirements.
Alternatives to Traditional Roof Lead
For projects where weight, cost, or handling concerns arise, non-lead flashing materials such as aluminium, bitumen, or lead-free composites can be used. These are easier to handle though they typically have shorter lifespans than traditional lead.
Installation and Maintenance
Correct installation is essential for maximising the life of roof lead. This includes using the correct code for the application, that allow for thermal movement, and fixing with appropriate clips or nails. Regular inspection will help spot any signs of cracking, lifting, or displacement. Always repair promptly to maintain protection.
