Lead flashing was commonly used on chimneys, around other roof penetrations such as vent pipes, and roof junctions, such as valleys.
It is still used for this, but is less common because of its cost, and the availability of alternatives. Modern alternatives: pvc, butyl rubber etc. are often less durable.
It is used in sheets to create rain resistant junctions because it is soft and malleable and weather durable. The lead sheets are tapped with a rounded hammer around moulding shapes to conform to the shapes of the building they will be flashing. Because of the malleability of lead, these sheets can be shaped closely to awkward shapes, such as the junction of a sloping roof and a chimney, without the need for the sheet to be cut. Cuts in the sheet would create a potential leak site.
Copper is also used for this purpose as it is also durable and malleable. It is usually more expensive than lead.
Lead and copper should not be used in an area of roof where water is being collected for drinking water.
Lead or copper should not be used where run-off water will flow onto Zincalume coated steel, as this will increase the rate of corrosion. This may also void a manufacturer's guarantee on the product.
