More and more homeowners are turning away from asphalt shingles in favor of metal roofs, which are known to be more energy-efficient and eco-friendly. However, if you are not overly familiar with metal roofs, you may have some concerns you'd like addressed before committing to having this style of roof installed on your home. Here's a look at a few common concerns about metal roofs.
Won't the roof rust?
You've probably seen old, rusted-out metal roofs on barns and old houses. The metal roofs used today aren't like these old roofs. Most are coated in a mixture that contains zinc and resists rust. Some metal roofs may need to be re-painted or finished every decade or so to maintain their non-rusting properties, but many of the better-made aluminum alloy options don't even require this maintenance.
The one instance in which you may have to worry about rust is if you live near the coast. The salt in the air can cause steel roofs to corrode and rust, which is why aluminum roofs are recommended for these areas.
Will your home's structure support the weight of the roof?
If you have an older home, you may be worried that it won't be able to support the weight of a heavy roof. However, metal roofs are actually lighter than asphalt roofs. Those shingles weigh a lot more than they look like they would weigh. The average asphalt shingle roof weighs 2.7 pounds per square foot, whereas a metal roof weighs about 1.2 pounds per square foot.
How can something made from so much metal be considered eco-friendly?
Manufacturing huge sheets of metal may not initially seem like the most eco-friendly practice, but when you compare metal roofing to the alternatives, it's a pretty green option. Metal roofs last longer than asphalt ones, so less waste is generated. Also, a large portion of the metal used to make the roof typically comes from recycled sources. When you're done with the roof, it can be recycled once again. Also, since metal roofs tend to keep homes cooler in the summer and warmer in the winter, they minimize environmental impact by reducing fuel consumption.
If you're considering getting a metal roof, talk to a roofing contractor like Ringer Roofing & Skylight Inc in your area about the brand and style that is best for your home. There are many rust-proof, lightweight and eco-friendly options that will give your home the protection you desire.
