Lead flashing is a crucial component of lead roofing, particularly for many of London's properties. It involves the use of strips of lead, that have been shaped specifically to seal the junctions between roofs and walls or within the actual roof itself. Its main and very important function is to prevent water penetration.
There are different types of lead flashing used in roofing. Step flashing is used where a vertical surface meets a sloping roof. Each 'step' is interwoven with the roofing material for a waterproof seal.
There is also counter flashing, which is used over the top of other types of flashing to provide an additional layer of protection.
Valley flashing is deployed in the 'valleys' where two roof slopes meet. Given the high volume of water this type of roof creates, the malleability of lead is crucial for shaping the flashing to fit perfectly, enhancing the water-resistant quality of the roofing areas.

Given the unique nature of lead as a roofing material, its installation requires highly skilled craftsmen and specialist expertise. When correctly installed, a lead roof in London can typically last over a hundred years. The malleability of lead allows it to adapt to complex roof shapes and details, and this is where the skill of the craftsman comes into play.
Proper underlays and fixings are essential components of a correctly installed lead roof. The underlay acts as a secondary barrier against weather and enables the roof to breathe, while the fixings hold the lead sheet in place, accommodating its expansion and contraction depending on the type of weather.
