Are Metal Roofs More Likely to be Struck by Lightning?

Posted on: April 19, 2017

According to the National Lighting Safety Institute, an estimated 1 out of every 200 houses will be struck by lightning each year However the question remains, are metal roofs more likely to be struck by lightning?

It is well known that metal is a high electrical conductor but when it comes to lightning striking your metal roof, size matters. The area and height of the roof is more relevant as opposed to the actual type of roofing material that covers your home. Lightning is attracted to and more likely to strike objects that are:

  • Higher above the ground
  • Contain a larger surface area
  • Electrically charged
  • Thinner than surrounding objects

Should your metal roof be struck by lightning, it is most likely that the electrical current will be spread out and dispersed across your roof. This would not be the case if you had a more traditional roofing material as it would combust the moment lightning struck it and would cause immediate damage. If you are looking for a positive change, there are many benefits of equipping your home with a metal roof.

Benefits of a Metal Roof

The following are a few benefits of having a metal roof on your home versus a different type of roofing material:

  • Light Reflecting – Metal roofs are non-absorbent and reflect solar energy unlike asphalt roofing. Also, some metal roofs re-emit solar radiation and can even cool your home, reducing the cost of energy consumption in your home.
  • Ventilation Efficiency – With the right roofing contractor, a properly constructed metal roof will keep hot air circulating out of the attic space. This is important during the changing of the seasons when moisture can get trapped in your attic.
  • Going Green - If you are looking to have a more eco-friendly roof, metal roofs are the way to go. Most aluminum roofing systems are made from 98 percent recycled materials.
  • Fire Resistance – Worried about the combustibility of your roof? You don’t need to with a metal roof as most metal roofs are fire resistant.
  • Longevity – When investing long-term in your home, a metal roof is a great place to start. Depending on the material, some metal roofs can last 40 to 70 years. Whereas traditional asphalt roofing materials have an estimated life expectancy of 12 to 20 years.
