Lead is used for its qualities of robustness and malleability. With care it can be folded, cut and welded.
It is primarily used to produce waterproof joints at junctions of differing materials such as where a chimney connects with roofing slates or tiles, or when there is a change of direction such as a valley between sections of roof.
Working with lead is a skill that takes some time to learn. It can split if not correctly 'dressed' into shape and must be incised correctly into brickwork mortar joints in order to fully shed rain.
Some examples of our leadwork on roofs are shown below
