lead-fittingLead Flashing is strips of lead used to seal roofs. It is primarily used to waterproof joints and edges, such as when a there is an escarpment, or a corner in a roof. It is also used where chimneys or flat roofs meet walls or pitched roofing, and it’s appearance is synonymous with the architecture of traditional English buildings such as Churches, schools and stately homes.

When to replace lead flashing

Lead is a highly malleable material and it is highly weather resistant, in fact lead flashing and lead roofing in general has a life expectancy of over 100 years. After this time the lead can develop cracks and splits, not due to deterioration in the metal, but because if the flashing is attached to less flexible material e.g. sealed in brickwork the lead cannot expand and contract freely with the exposed material. This retarded expansion and contraction in relation to the rest of the roof causes the splits.

Lead is still a valuable material which makes it a target for thieves, especially as many buildings with lead flashing are both open to the public and are secluded. The government has taken steps to combat this but it is still a problem and many beautiful old buildings are being stripped of their lead.
