Metal roofs are known for their excellent resistance to the elements. But another reason for their growing popularity is that they are one of the most environmentally friendly roofing solutions on the market. Read on as A1 Siding and Roofing, your trusted roofing contractor, explains why:
Longevity
The Metal Roofing Alliance claims that the service life of a metal roof is usually two to three times longer than typical asphalt shingle roofs. Metal roofs also last significantly longer than other roofing materials, according to the Building Owners and Managers Association (BOMA). The longer a roof lasts, the fewer times it will need to be replaced, which results in less waste in the landfills.
Energy Efficiency
A three-year-study by Oak Ridge National Laboratory’s Buildings Technology Center found that the high solar reflectivity and emissivity levels on cool metal roofs can help mitigate urban heat island effects. Moreover, while white coatings on most roofing materials displayed a drop of up to 40% in their initial reflectance, metal retained most of its solar reflectance during the three-year study. In fact, pre-painted metal was able to keep 95% of its reflectivity. Another study showed that unpainted metal roofs have a very high reflectance level, exceeding the minimum requirement of ENERGY STAR® which is 60%. This makes metal a sustainable choice for both residential and commercial roofing systems.
Recyclability
Lastly, metal roofs are favored by many green enthusiasts because of their unmatched recyclability. Research conducted by the Florida Department of Environmental protection found that metal is the most environmentally friendly roofing solution. Many metal roofing systems contain up to 40% recycled steel while the content of metal in itself is completely recyclable. Thanks to its high reusability and recyclability, materials from a metal roof rarely end up in landfills.
The facts above make it clear why metal is an eco-friendly solution for homeowners.
