Myth’s of Metal Roofing Debunked!

The Durability & Strength of Metal Roofing



Myth vs Fact

Isn’t it funny how we hold onto myth’s for so long that they eventually become like facts to us?

Have you ever heard the statement “Lightning doesn’t strike the same place twice.”? I am sure that like me you probably thought this was true, just because it has been said for years, however, NASA released a study in 2003 involving 386 cloud-to-ground strikes and found that over a third of the strikes branched and hit multiple locations at once. Not only does lightning strike twice, but it can also strike two places at the same time!

When it comes to metal there are many myths that society has held onto for years. Here are a few examples, and the truth about them.

Myth #1: Metal Roofing Attracts Lightning

Have you ever been told to not hold onto anything metal during a thunderstorm because “metal objects attract lightning.”? This is actually a myth. The idea that metal attracts lightning is partly because most lightning rods put on top of buildings are made of metal. But these rods don’t actually attract lightning strikes; instead, the metal rod acts as a conductor of electricity and channels the electricity safely to the ground so it doesn’t damage the building.

So what does this mean? Metal roofing does not increase the risk or likelihood of lightning strikes. It has the same possibility of any other material to be struck by lightning.  So the fact of the matter is that it depends more on the lay of the land, the height of the structure, and where it is located.

Myth #2: Metal Roofs are Noisy

If you took a poll, most people would tell you that metal roofs make a lot of noise during rain or hail storms. While it is true that some systems and profiles of metal roofing can experience noise in certain circumstances, most metal roofs are designed and installed to be no louder than any other roof type. Some can even be quieter.

That being said, there are some home owners who want to hear the noises from rain or hail. Luckily, you can have metal roofing installed in a way that makes noise as loud or as quiet as you prefer. There are ways to ensure a roof doesn’t experience unnecessary noise. Talk to your contractor about the way your roof will be structured, the type of insulation that will be used, and his knowledge and experience in installing metal roofing materials. All of this will make a difference in the noise level you will experience.

Myth #3: Metal Roofs Dent Easily

“Contrary to popular belief, metal roofing is actually very difficult to dent and even more difficult to puncture. There is always a concern among consumers that the first time a wave of hail rolls through, there will be dents all over a metal roof. In actuality, the average hail storm is very unlikely to cause damage or dent a metal roof. The possibility for denting increases as the size and quantity of the hailstones increase, but it would take a huge storm with extremely large pieces of hail to create any significant denting or penetration points.”

* If you live in an area where hail storms occur, consider a metal roof with a rib roller or striation in the flat part of the panel because it could help hide any denting that could show up after a large hailstorm.
