What are the rules for lead roof flashing?

In the UK and across the world, rules for lead roof flashing to ensure safety, durability, and effectiveness in protecting buildings from water ingress. Lead is a highly durable material, but incorrect installation can cause issues such as leaks, corrosion, or structural damage.In the UK, lead roof flashing must adhere to guidelines set by the Lead Sheet Training Academy (LSTA) and British Standards (BS EN 12588). The rules show that lead must be of the correct thickness, typically between Code 3 and Code 5, depending on the application. Flashing should be installed with sufficient overlap to ensure water tightness, typically 100mm for most roof pitches. Fixings must allow for thermal expansion and contraction to prevent cracking, with provisions for free movement such as sliding clips. Proper sealing with lead sealant or mortar is essential, and lead must not be over fixed or excessively long to avoid buckling. Additionally, health and safety standards must be followed, particularly for working at height.
