Does a Metal Roof Attract Lightning?


As summer approaches, we often get asked whether metal roofs are more likely to get struck by lightning.  Makes sense, right? Most metals are conductive of electricity. So logically, it seems metal would attract lighting. The truth is however, a metal roof is no more or less likely to get struck by lightning than any other type.

Lightning strikes the highest point and building strikes are rare. Lightning will typically strike a nearby tree or telephone pole. However, your risk for a lightning strike does increase if your home is the highest structure in your surrounding area.

Is it a Good Idea to Install Lightning Rods?

It is not necessary to install lightning rods on your metal roof, in most situations. If your roof is the highest point of a surrounding area, you may consider having a lightning safety system installed on your home.  In the event of a strike, a lightning safety system is designed to filter the flow of electrical current safely away from the home. Ensuring it is installed and grounded correctly is important, so we recommend that you get a professional involved.

What If Lightning Does Strike My Metal Roof?

In some ways metal roofs are ideal in the event of a lightning strike.  A metal roof will disperse the energy safely through the structure if struck. Metal isn’t combustible or flammable,  which makes it a low risk and desirable roofing option where severe weather is concerned.
