Lead flashing failure in Edenbridge is accelerated by Eden Valley humidity keeps chimney stacks perpetually damp. The housing stock — historic High Street timber-framed and brick-built properties — means the majority of lead work we attend in Edenbridge is on pre-1940 properties where the original flashing specification was modest and has not been upgraded since.
The most common pattern on Edenbridge properties: Code 3 flat-lapped lead installed 10-15 years ago is now splitting at lap joints and admitting water that tracks to a ceiling drip remote from the actual entry point. The correct fix is Code 5 with welted joints and a correctly chased top edge — this lasts 40 years in Edenbridge's conditions rather than 10.
