Metal roofing is no more likely to attract lightning strikes than any other roofing material on the market today. In fact, having a metal roof in place may even be an advantage if a building is ever struck by lightning. Metal roofing is a non-combustible material with the highest Class A fire-resistance rating, which means homes and businesses should invest in this roofing material.
What Happens When Lightning Strikes A Metal Roof?
Especially in a lightning-prone area, investing in metal roofing can certainly have its advantages. When lightning strikes a building or home, it does not matter if the material that is struck can conduct electricity. If your roofing happens to be covered by combustible materials, including wood shakes or flammable asphalt shingles, these materials are ignited easily. These flammable materials are known as “channels through” on the lightning’s way to the ground through the building’s pipe and electrical system.
Metal Roofing And Lightning Strikes
Essentially, there is nothing you can do to lessen the risk or probability of lightning striking your roof. Lightning strikes are influenced by these factors: building height/size, topography and geography. Lightning is drawn to the highest points of any area, so the taller the building is, the more likely it is to be struck. Geography simply refers to your location – is your area more or less prone to lightning activity?
So, what happens when lightning actually strikes a home or building? A lightning strike should always be taken seriously. A few factors can affect the severity of the strike, including the building materials on the inside and outside. If the building was constructed of non-combustible materials, it will reduce the chance of a fire outbreak. Of course, flammable materials found on the inside will make the building more susceptible to ignition.
Metal Roofing Reduces Lightning Threats
Metal Construction (MCA) recently stated that metal roofing is no more or less likely to be struck by lightning than any other roofing material. In fact, a properly grounded metal roof should conduct energy of the lightning strike over a broader area of the roofing, which will reduce the amount of heat transferred and reduce the risk of a damaging fire, altogether. Due to the lessening of lightning risks, many believe metal roofing is actually one of the most desirable roofing types today.
When lightning strikes metal roofing, it is conducted away towards either the ground or another conductor nearby. Metal roofing can protect the home or building from both the lightning’s heat and electrical current. While metal can keep you safe, it likely won’t prevent property damage.
Consequences Of Lightning Strikes
Lightning strike fatalities have declined lately, with only 27 deaths per year recorded from 2009-2018. Property damaged cause by lightning, though, remains a different story. Rising costs of construction and labor can make lightning strikes very expensive for home and business owners.
