Metal roofs are an attractive option because they are long-lasting, require little maintenance and are energy efficient. They’re a fantastic choice in Southern California because they are fire-resistant. There are many materials to choose from, including copper, galvanized steel and aluminum. Here are three reasons to consider metal roofs from a sustainability perspective.
Depending on what type of metal roof you choose, they are made of 25 to 95% of recyclable content. In addition, then that roof needs replacing (in a whopping 40 to 70 years), 100% of those materials are recyclable.
According to the Steel Recycling Institute, steel roofing comprises about 80 percent of the roofing market for its long-lasting and durable appeal. Because they’re available in a multitude of shapes and colors, there also are a lot of aesthetic options with this type of roofing material.
Because metal roofs reflect solar radiant heat, they can bring your cooling cost down by 10 to 25%. Your home insurance company may even be able to offer discounts for metal roof installation, as they are more durable than other types of roofs. Want to reflect even more heat? Go with lighter colors. Just as you wear lighter colors in the hotter months, a lighter-colored roof will absorb less heat.
Metal roofs aren’t just easy to install – they’re about half the weight of asphalt. Meanwhile, shingle roofs create 20 billion pounds of waste a year! Because they are so long-lasting and don’t require as much maintenance, that is additional waste that is saved by choosing a metal roof.
