Metal roofing materials are primarily manufactured from aluminium and steel, as they are economical, relatively easy to work, are durable and able to receive a number of different finishes.
Steel is heavier than other metal options but as a result is sturdier and can be coated with a range of finishes to provide protection against rust and corrosion as well as to provide colour. Aluminium is more lightweight and is resistant to rust. However, it is more expensive, and relatively soft and so is more prone to denting and marring.
