Metal Roofing: Copper Roofing, Zinc Roofing, Stainless Steel Roofing, Aluminium Roofing

We install your copper roofing using fixed or sliding clips. We know your choice of this type of metal roofing included considerations such as its light weight, durability and ability to be formed to complex roof designs significantly improving building aesthetics and prestige.

Zinc roofing is known to outlast all other materials, and as such, its durability is a key consideration for its selection.

Aluminium roofing is specifically lightweight and suitable for barrel vaulted roofs. Because of the unique challenge of being difficult to weld compared to other materials, it requires more skill for application in complicated projects or roofs with a lot of pipes and other penetrations coming through.
