Two of the most popular roofing material options are metal panels and asphalt shingles.
One way metal roofing stands out above asphalt shingles, is it is better for the environment. Metal is both energy efficient, sustainable, and 100% recyclable at the end of its lifetime (Cool Metal Roofing Coalition). While the price tag on a metal roof may be higher than that of asphalt shingles, metal roofs are durable and require little upkeep. Asphalt roofs need to be replaced after 15 or 25 years, but metal roofs are fire-resistant and weather-resistant, and can remain from 40 years to a lifetime!
Meanwhile, asphalt shingles cannot be re-used or recycled. Since incinerating these shingles releases harmful gas emissions, shingles are rarely burned. So what happens to all the unwanted shingles from house re-roofing projects? In the United States alone, eleven million tons of shingles per year are added to landfills, where they will stay for another 300 years (The National Association of Home Builders). To put new asphalt shingles down, the existing ones must be removed, but metal panels can be installed directly over existing roofing.
Most metal roofing is also coated with “cool coatings” that reflect sunlight and reduce the need for air conditioning, saving the consumer more money.
