Lead has been used as a water and weatherproof finish on Essex & Kent buildings for hundreds of years. This is because leadwork is very durable, and is perfect for cutting and shaping by hand. Leadwork has a high resistance to erosion which means it will last much longer than other roofing materials. Leadwork can be used as the main roof covering or to create flashing, box gutters, run out valleys or to create junctions between walls and the main roof.
