Lead work is the name given to the many uses of this material in the roofing industry.
Lead is one of the oldest roofing materials and thanks to its durability is still used today. This bluish-grey material is extremely resistant to the weather and atmospheric pollution which makes it an ideal choice for roofing contractors.
Advantages of lead
The main advantage is its flexibility as lead expands or contracts according to changes in temperature. This is particularly useful in regard to roofing when you consider the constant changes in temperature due to the unpredictable nature of our weather.
A roof is constantly exposed to these changes which gradually reduces its effectiveness over time. It’s weatherproofing starts to degrade which enables water to seep in and cause damage to the timber, joists and overall structure.
But this is where lead proves its worth. It acts as a sealant wherever there is a join between two surfaces, for example lead flashing. This type of flashing is used as a barrier between a roof and the neighboring brickwork.
Lead also acts as a covering for joints, guttering or as a complete roof covering. Its malleability means that it can be manipulated into a variety of shapes and sizes – a method known as ‘dressing’ – to suit any roof repair.
