Flashing has traditionally been used as a joining or sealing agent. Wherever slates or tiles meet another fitting – roof valleys, chimney stacks or skylights for example, you will find flashing.
The key purpose of lead flashing is to stop water seeping into the main structure from a joint.
For centuries lead was the industry’s metal of choice - it is a relatively soft substance that is easy to mould without splitting or cracking – and it will remain effective for many, many years.
Today, other metals – such as zinc – are becoming increasingly popular, providing a great alternative. At Pro Dec Roofing we are happy to discuss the best option for you.
