Global Home Improvement Case Studies: 3 Common Myths About Metal Roofs

Tuesday, April 3rd, 2018 by Michael Gabrian


When it comes to installing a new roof, a lot of people are curious about a metal roof replacement, but ultimately shy away because of concerns over a few myths. 

Here are some of the most common ones.

1. Metal Roofs Attract Lightning

It’s totally understandable why this is a big fear. Don’t worry though. Lightning is not attracted to metal roofs. Lightning is attracted to high points. So look at the tallest point in your area; mountains, tall buildings, trees, etc.

Metal is an electrical conductor, so what this means is that if lightning does strike your roof, the energy would disperse evenly across the roof, limiting it’s actual damage. You see, with an asphalt roof, that lightning would strike your rook and probably just combust in that one spot resulting a fire. Metal roofs actually protect you from that damage. You’re much safer from and lightning and fire damage with a metal roof than an asphalt roof.

2. Rain that Hits Metal Roofs is Louder

This one makes a lot of sense too. Naturally, it’s easy to assume that rain will make more noise on a metal roof than an asphalt roof. This isn’t the case. Under the metal roof is typically a solid deck, underlayment, and some insulation. This actually reduces a lot of the noise. Rain hitting a properly installed metal roof actually only make 6 decibels more noise than on an asphalt roof. Humans can’t actually distinguish two sounds that are up to 8 decibels apart. So when it comes down to it, you wouldn’t actually be able to tell the noise difference between a metal and asphalt roof.

3. Metal Roofs Don’t Perform Well in Poor Weather

It’s not uncommon to fear hail denting your standing seam metal roof or your metal roof to absorb heat, making the house hotter, or colder, etc. Metal roofs have two huge advantages; their durability and their energy efficiency. So for one, your metal roof, especially if made of steel, will absolutely be strong enough to withstand some hail. The aesthetics and performance of your roof will be protected.

Rather than absorbing heat from the sun, heating up your home in the summer, metal roofs reflect heat from the sun. This alleviates stress put on your air conditioning in the summer and ultimately will help save you money on your energy bills.


Now that we’ve busted some of these myths, I think it’s important to touch upon some of the benefits you’ll see with a metal roof.

For one, they’re more durable. Wind won’t blow pieces off like they will to asphalt. You can also rest assured that your home will be more protected from impacts from branches and such.

Another big benefit is the energy efficiency. The metal roof actually reflects the heat of the sun more efficiently, rather than letting it pass through the roof. This helps keep internal temperatures stable.
