Copper Roof
Copper, Steel, Aluminum and Zinc Custom-Made Roofing



A copper roof is a distinctive roof! It adds greatly to the resale value of your property. Copper is lightweight at approximately 144 lbs per square. This means less structural reinforcement is needed for the roof. Compare this to 350 -750 lbs per square from many other roofing materials. Copper is affordable when compared to materials such as: slate, tile or cedar. When you compare the lifetime costs of a copper roof it is one of the least expensive materials. A roof installed by Metal Roof Systems, Inc. should last well over 100 years! It is environmentally friendly and can achieve a class “A” fire rating.

The rate of patina change is dependent on your climate. Patina change refers to the tarnish that forms on the surface of copper, as a result of age and exposure. It gives copper that unique green look, and it also provides a protective layer that would otherwise cause it to be damaged by weathering. This example of patina change from 1-11 years is for a seaside environment. A roof inland could take 3 times longer to achieve the green-like color. However, copper can be treated to accelerate the patina process. It depends on the client’s preference.

Copper can be used for both residential and commercial buildings to give a distinct look. The possibilities are endless!
