Advantages of Lead Roofing

Lead is a great material for roofing because of how easily it expands and contracts with the temperature. This makes it a very reliable roofing material because it can match the constant changes in temperature during the day.

Because of this ability, lead flashing can act as a barrier against rain and moisture for a lot longer than standard flashing. This in turn protects key roofing components such as the timber or joints from the weather.

Lead roofing is also very malleable, which means that it can be bent and moved into new shapes to fit different purposes. This allows it to help a variety of different roofing projects and designs. This manipulation of lead to be used for roofing is a method known as dressing.

As well as benefiting the waterproofing of your home, lead roofing is one of the most environmentally friendly building materials available. It’s energy efficient as most standard lead roofing has an energy rating of A to A+. Lead also has a considerably smaller carbon footprint compared to most other building materials.

The Lead Roofing Association, one of the most influential professional partners in the lead roofing industry, have produced a short film ‘The Truth About Lead’ which explains the findings of a recent study into how lead roofing can improve a building’s carbon footprint.

In summary:

  • Lead has an established recycling infrastructure, which cuts out on waste products
  • Lead has a much lower carbon footprint when compared with other hard metals
  • The long-life span of lead complies with Euro code requirements, which is perfect for architects
  • Lead is not impacted by cold or wet weather, so roofing projects will not run over
  • The lifespan of lead is thought to be around three times longer than other flashing products.
