There’s a common misconception that metal roofs attract lightning. However, Indiana Metal Roofing Systems, based in Fort Wayne, IN, assures homeowners that metal roofs are not more likely to be struck by lightning than other types of roofing materials. In fact, metal roofing is one of the safest options during a thunderstorm.
Why Metal Roofs Are Safe During Lightning Strikes
Contrary to popular belief, metal roofing is safe during lightning strikes for several reasons:
Metal conducts electricity efficiently – When lightning strikes a metal roof, the electrical charge is evenly distributed across the surface, reducing the risk of concentrated damage.
Metal roofs are grounded – Building codes require metal roofs to be grounded with a lightning protection system, further mitigating any risk. These systems redirect the electrical charge safely into the ground.
Metal roofs are non-combustible – Unlike wood or asphalt shingles, metal roofing materials won’t catch fire during a lightning strike.
How Lightning Works and Its Relation to Metal Roofs
Lightning strikes where there is a path of least resistance—but this doesn’t mean metal roofs are more likely to be struck. Lightning typically strikes the tallest object in an area, regardless of the material it is made from. Since metal is an excellent conductor of electricity, if lightning does strike a metal roof, the electrical current will spread out evenly across the surface and be safely grounded. This minimizes the risk of structural damage or fire.
Comparing Metal Roofs to Other Materials
Wood roofing: A lightning strike on a wood roof poses a high fire risk since wood is combustible.
Asphalt shingles: These can melt or catch fire during a lightning strike, potentially leading to leaks or other issues.
Concrete tiles: While resistant to fire, they can crack or shatter if struck by lightning, requiring expensive repairs.
Fact: According to the National Lightning Safety Institute, the probability of any building being struck by lightning in a given year is only 1 in 200.
Do Metal Roofs Need Special Lightning Protection?
While metal roofs are safe, homes in areas prone to thunderstorms should still consider installing a lightning protection system (LPS). These systems consist of conductors and grounding rods designed to direct the electrical charge safely away from the structure. Modern building codes often require metal roofs to be grounded, ensuring additional protection in case of a lightning strike.
Other Considerations for Metal Roofs
In addition to concerns about lightning, some homeowners worry about the following:
Noise during rain or hail: Metal roofs can be noisier than other materials during heavy rain or hailstorms, but adding insulation can mitigate this issue.
Dents from debris: Softer metals like aluminum are more prone to denting when hit by hail or debris.
Expansion and contraction: Metal roofs expand and contract with temperature changes, which can cause fasteners to loosen over time.
Corrosion: While many metals used in roofing are rust-resistant, certain metals like steel can corrode if not properly maintained.
Maintenance: Metal roofs may require occasional upkeep, such as tightening screws, sealing seams, or painting.

FAQs
1. Is a metal roof more likely to attract lightning?No, metal roofs are no more likely to be struck by lightning than other materials.
2. Does a metal roof need grounding?Yes, building codes typically require metal roofs to be grounded, which helps protect the home during a lightning strike.
3. Will a lightning strike damage a metal roof?Since metal distributes electrical charges evenly, it’s less likely to suffer concentrated damage from a lightning strike compared to other roofing materials.
4. Can a metal roof catch fire from lightning?No, metal roofs are non-combustible, so they are unlikely to catch fire during a lightning strike.
5. Should I install a lightning protection system if I have a metal roof?If you live in an area with frequent thunderstorms, installing a lightning protection system is a good idea for added safety.
Conclusion
