Typical Lifespan of Corrugated Metal Roofing
If you are planning to put a roof on a building, then you may want to consider using corrugated metal roofing especially if it is for an out building. Roofing of this kind has many advantages over asphalt roofs and has a life span from 20 to 100 years depending on grade.
Materials Used in Corrugated Metal Roofing
Corrugated metal roofing is normally made from metals such as stainless steel, copper, zinc and aluminium. When the base materials oxidize they create a protective patina. It is fairly common practise today to coat corrugated metal roofing in an zinc aluminium alloy to provide protection against corrosion.
Advantages of Corrugated Metal Roofing
Corrugated metal roofing is made from recyclable materials, and therefore corrugated metal roofs are far more friendly to the environment. "Kynar", is a reflective material which is used to reflect the rays of the sun away from the building. This has been shown to save 25-30% on air conditioning costs.
They are light weight and portable, and are require little or no maintenance. They are used for all types of buildings due to their high strength to weight ratio.
Incompatible metals will produce excessive and rapid corrosion. It is rare that corrugated metal roofing can be sourced locally. This may incur financial and environmental cost.
