Metal roofing is available in a variety of materials. These metals bring a combination of strength, flexibility and longevity that will complement any home.
Aluminum is a choice for virtually any roof, whereas steel or other materials are being considered. Its natural properties, such as light weight, strength and longevity, make it a desirable roofing material.
These qualities make aluminum the number one metal for the aerospace industry, so it only makes sense for aluminum to be equally popular in the roofing industry. Because aluminum roofs are lightweight, consumers can re-roof their home and reduce the weight on their housing structure. Unlike heavy tile and slate roofing, aluminum roofing does not require structural reinforcement.
The other important factor to consider is an aluminum roof's resistance to rust and corrosion over time. These unique characteristics make aluminum roofing the preferred material in salt spray coastal environments. Roof shingle aluminum roofs not only provide premium protection, but they are also great for the environment.
According to the Bureau of Cedar Shakes and Shingles, three full grown trees are destroyed for an average shake roof. One study has shown that composition shingles buried in landfills will take over 300 years to decompose. Aluminum roofing shingles are completely recyclable and often have a high recycled content.
And lastly, because aluminum is more malleable, it can generally be formed into more intricate and detailed product designs, which allow the building of strength and beauty into a roof. Galvalume steel is an ideal roofing material because of its strength, extraordinary outdoor corrosion resistance and longevity.
Steel roofing used in residential applications today is metallic coated with either Zinc (G90) or zinc / aluminum (AZ50) to provide the corrosion resistance homeowners desire. Steel roofing is strong and therefore gives higher wind uplift resistance and a broader range of application than other roofing materials. As a result, an installed steel roof system has a broader range of price levels and products than many other kinds of metal roofing. Steel roofs have passed the UL 90 wind tests due to their strength and weight.
Steel roof shingle - today's quality steel roofing offers excellent rust protection as well. Galvanized steel roofing is available as painted, aggregate-coated or with a mill or a bare finish. Unlike conventional, non-metallic roof systems, Galvalume steel roofs won't crack and peel when subjected to the sun and weather.
