The 4 Top Environmental Benefits of Metal Roofing

As consumers learn more about the need for sustainable living, many homeowners are prioritizing eco-friendly living in their home and remodeling budget. To meet public outcry for conservation, recyclability, and sustainability, those in the home improvement and construction industries are seeking proven alternatives that will adhere to even the most rigorous standards of sustainable living. Of the various home improvement green solutions, metal roofing is definitely one that is gaining great popularity even among the most skeptical homeowners and buyers as it is the second most popular roofing material currently in the US and Canada is quickly following suit.


The Rise of Metal Roofing

Made of various metal roofing materials — such as tin, aluminum, copper, and galvanized steel — metal roofs are known to withstand some of Mother Nature’s most wicked storms. Be it heavy rain, hail or snow, metal roofs will keep homeowners safe and away from all kinds of windblown debris and natural elements. In addition to being fire-resistant and impervious to the most unforgiving weather and troublesome pests, metal roofs are also an environmentally-friendly roofing solution for their unmatched longevity, superior energy saving features, and high recyclability.

1 – Longevity

According to the Metal Roofing Alliance, the typical life cycle of a metal roof is two to three times longer than that of asphalt shingles and when the roof is finally replaced the metal can be recycled, unlike asphalt. Building Owners and home lovers find metal roofs have a significantly longer expected life than all other roofing materials that is backed by 50+ Warranties. Metal roofs are malleable and can be pressed and shaped without suffering any breaks or cracks. This also allows them to be installed existing asphalt shingles, avoid a tear off and waste in our landfills. Lasting considerably longer than the average 15- to 23-year roof life of asphalt shingles, a metal roof can last up to 60 years and beyond. Combined with its minimal upkeep, it is no wonder that homeowners love metal roofs for their generous financial savings in roofing repairs and final replacement.

2 – Energy Efficiency

Using a solar spectrum reflectometer and an emission meter to conduct their three-year-study on the energy efficiency and service life of metal roofing systems, Oak Ridge National Laboratory’s Buildings Technology Center found the high solar reflectivity and emissivity levels of cool metal roofing can greatly mitigate urban heat island effects. Moreover, while white coatings on other roofing materials displayed a 25%-40% drop in their initial reflectance, metal roofing retained most of its initial solar reflectance during the three-year study. In fact, the researchers found that pre-painted metal was able to keep almost 95% of its reflexivity.

Another study showed that an unpainted metal roof demonstrates a very high solar reflectance level that usually exceeds the minimum federal EnergyStar requirement of 60%. Depending on the color of a painted metal roof, the reflectance range can go anywhere from 10% to 75%, which is definitely better than the 5% to 25% range of an asphalt roof. As a recent case study on the trend of cool metal roofing in North America points out, dark colors can absorb significantly more solar radiation than light ones. Therefore, switching to a white- or light-colored metal roof will not only reduce energy spending by 20%, but also make your home 50 to 60 degrees cooler than a conventional dark-colored roof.

3 – Recyclability

Finally, the unmatched recyclability of metal roofs makes them a favorite of many “ECO” enthusiasts. According to our research, metal roofing is the most eco-friendly roofing solution. Many metal roofs contain up to 40% recycled steels, while the content of metal roofs in itself is 100% recyclable. As a result of its high recyclability and reusability, most metal roof materials rarely become waste in a landfill. When compared to Environmental Protection Agency’s (EPA) estimation of 11 million tons of asphalt shingles ending up in landfill, it is clear why those in the government agency and home improvement industry are calling metal roofing an eco-friendly solution for every homeowner.

4 – Eco-Friendly and Energy Efficient Homes

As Home reports, metal roofs are commonly known for improving home value by 1 to 6 percent. The trend for going green is not slowing down anytime soon. In fact, research done by various groups has unanimously found a growing interest in eco-friendliness and sustainable living among both homeowners and buyers. According to a study conducted by the National Association of Realtors, an overwhelming number of homebuyers are making energy efficient appliances, lighting, and other home accessories top priorities in their home purchases. Of the surveyed homebuyers, 94% are looking for Energy Star-rated appliances, while more than 90% explicitly declared their desire to have an Energy Star rating for the whole home. In another survey, the National Association of Home Builders found that 94% of existing green homeowners would recommend a green home to a friend. As the public moves toward a more sustainable lifestyle, an increase in metal roofing for both commercial and residential buildings is anticipated.

  1. My nephew recently moved into an older home with his wife. He has noticed some leaks in his roof, and he wants to have a professional give him quote for replacement. I didn’t realize that metal roofs can come with a 50+ year warranty. That longevity makes it a good option for my nephew.
