Myths live on for generations and will continue to do so until they're debunked. You've likely heard a few myths about metal roofing, and you may not be sure whether they're true or not. Below are common metal roofing myths debunked.
Metal Roofs Are Noisy
This is true to some extent. Metal roofs are noisy, but that's dependent on the type of installation. For example, if you install a metal roof on your house, you'll need to add an underlayment that will help reduce the noise.
This is why old barns are noisy when it rains, but it doesn't mean that all metal roofing is noisy. Ensure that your metal roof is installed by an experienced contractor who is knowledgeable in proper metal roof installation.
Metal Roofs Are Heavy
Contrary to popular belief, metal roofs are light, especially if you're working with aluminum. Aluminum metal sheets are lightweight and weigh about 50% less than asphalt shingles. They're also weatherproof and thus don't require constant reroofing, which adds to the weight. Your deck should support the new metal roofing if it managed to support the weight of shingles.
Metal Roofs Are Hot
That's correct. Metal roofs are hot as they tend to reflect light and have a higher emissivity. They'll deflect heat energy instead of absorbing it as shingles do. This means that metal roofs are hot to touch; thus, avoid walking barefoot on your roof when making repairs.
Since they reflect heat and light, metal roofs are energy efficient. Also, the metal roof will not affect the temperature in your home during winter as it's dependent on the insulation used in the attic.
Metal Roofs Aren't Durable
Metal roofs are thin sheets; some owners think they're flimsy and not durable. However, it's easy to spot homes that have had metal roofing for decades. This tells you that they're durable, and thanks to technology, metal roofs will resist oxidation.
If you choose strong gauges, your roof will deflect hail and hide imperfections. Large hailstones can dent your metal roof, but they'd need to be extremely large to penetrate through the sheets. Also, metal roofs have a class A rating — which means they're effective against fire exposure.
Metal Roofs Are Expensive
Yes, the initial cost is higher compared to asphalt roofing. However, metal roofing requires less maintenance and can last up to 70 years. If you calculate the lifetime cost of installing and maintaining a metal roof, you'll notice that it's cheaper than asphalt roofing.
