Lead is an element that is naturally occurring throughout the environment. It is a soft, malleable, heavy metal, with a density that exceeds that of most common materials. It has a number of properties that have made it a useful construction material for hundreds of years:
- High density.
- Low melting point.
- Resistance to oxidation.
- Ease of extraction.
The benefits of lead roofs can include:
- Life expectancy: Properly installed, a lead roof should have a long lifespan, being resistant to harsh weather, fire, mildew, infestation and rot.
- Ease of installation: Due to its malleability lead is a relatively easy material to work with as it be cut and formed on site to complex shapes and is relatively quick and easy to install.
- Minimal roof pitch: Lead can be installed on gently pitching roofs without the danger of water penetration.
- Rain and snow shedding: Lead roof surfaces are hard and relatively ‘slippery’, meaning they tend to shed rain and snow relatively easily.
