Metal Roofing and Lightning: What You Need to Know

by | Oct 22, 2021 | Roofing

If you are considering upgrading to a metal roof, then you may be wondering whether you are at an increased risk of a lightning strike. However, you can rest assured, as evidence suggests that you are not in fact at an increased risk of a lightning strike.

Now, that may sound weird, especially as metal is a conductive material, suspected to attract lightning, not deter it. However, metal roofs may actually protect you against lightning strikes. This is because metal roofs contain excellent fire resistance, reducing the likelihood of a fire or further damage if struck.

So, this blog post will discuss more on metal roofing and lightning, covering everything you need to know.

Reduced power surge likelihood

In the event of a lightning strike, the lightning can cause a surge within the home, damaging electrical devices. However, a metal roof does a better job of spreading the electrical surge across the roof and to the outside of the property. This is a whole lot less dangerous, reducing the risk of an explosive surge or further damage to the property.

Metal roofs cannot catch on fire

Properties struck by lightning run the risk of catching on fire. Particularly, this is the attic catching fire, spreading to the rest of the property. However, metal roofs have great fire resistance, practically impossible for the attic to catch on fire.

For this reason, metal roofs are popular in lightning-prone areas. So, while it may sound counterproductive at first, a metal roof may actually be what you need to reduce stress, and increase safety.

Further costs of lightning damages

If lightning is to hit your home without a metal roof (and sometimes with, although the probability is less), you may suffer further damages and costs. For example, a boiler may explode, a power surge may take place, damaging electrical devices and potentially your mains electric, and you may sustain fire damage.

If the appropriate precautions are not taken, not only is this extremely dangerous, but it can also rack up quite the bill.

The bottom line

Metal roofing has become more and more popular, especially for those living in areas greater prone to lightning strikes. While at first, it may seem a little backward and metal is a conductive material, it actually provides greater protection and does not increase the risk of lightning striking your home.
