If you’re considering upgrading to a metal roof, chances are someone has warned you:
“Be careful—metal roofs attract lightning!”
Let’s go ahead and strike that myth down. ⚡
Metal roofs do NOT attract lightning. In fact, they’re one of the safest and most storm-resilient roofing options on the market.
Lightning doesn’t seek out metal—it seeks the path of least resistance to the ground. That usually means tall structures like trees, towers, or chimneys. If your home is the tallest structure in an area, it has a higher chance of being struck regardless of what kind of roof it has.
According to the Metal Construction Association:
“The presence of metal on a structure does not influence the risk of a lightning strike. Metal roofing, in fact, can be beneficial in a lightning event because it is noncombustible.”
Why Metal Roofs Are Actually a Safe Bet During Storms
-
Non-Combustible: Metal doesn’t ignite or burn. If your home does get struck by lightning, a metal roof will help prevent a fire from starting—something wood or asphalt shingles can’t guarantee.
-
Disperses Energy Safely: A properly grounded metal roof can safely disperse electrical energy throughout the structure and into the ground, reducing damage risk.
-
Durability: Unlike other materials that can splinter or melt, metal remains intact even during extreme weather events.
What Does Attract Lightning?
-
Height: The taller the structure, the more likely it is to be struck.
-
Isolation: A lone building or tree in an open area is more vulnerable.
-
Pointed Shapes: Sharp, protruding points are more likely to collect a lightning discharge.
If you’re worried about lightning, the best protection isn’t changing your roofing material—it’s installing a lightning protection system, which includes air terminals, grounding rods, and conductors.
Bottom Line
Metal roofs do not attract lightning. But if your home does take a hit, a metal roof is one of the best defenses you can have. It’s strong, fire-resistant, and will help protect your home and family when it matters most.
So next time someone tells you metal roofing is a lightning magnet, feel free to hit them with the facts—and maybe send them this article.
