Lightning strikes cost nearly $1 billion in insured losses in 2011, according to the Insurance Information Institute. Many times, these strikes can land on or near residences, wreaking havoc on the homeโs electrical system, appliances or electronics. โThereโs so much more valuable electronic equipment in homes today,โ says Bud VanSickle, executive director of the Lightning Protection Institute (LPI). โThe loss from lightning can be tremendous.โ
Fortunately, by following these pointers, you may help safeguard your propertyโand yourselfโfrom the damage inflicted by lightning.
Know the numbers. Lightning is not always taken seriouslyโbut it should be. โItโs an occasional danger, but a tremendous hazard,โ says VanSickle. The stats prove it:
- During a thunderstorm, donโt let dry conditions fool you. Lightning can strike up to 10 miles away from an area of rainfall. 1
- Lightning causes an average of 55โ60 fatalities yearly. 2
- The air surrounded by a lightning strike can heat as much as 50,000 degrees F. Thatโs about five times hotter than the sun. 3
- Each year, the United States experiences 25 million flashes of lightning.4 Florida and other Gulf Coast states see the most lightning; Pacific Coast states see the least.
- A single strike of lightning can pack up to 1 billion volts of electricity. 5
Invest in lightning protection. โA direct lightning strike with no path to follow will use any available path, such as electrical wiring not designed to handle lightning, metal plumbing pipes or metal gas system lines,โ says VanSickle. Your best bet for stopping lightning damage in its tracks? A lightning protection system tailored specifically to your homeโs architecture. Such a system creates a pathway for lightning bolts, guiding them safely into the ground. When properly installed, lightning protection systems are 99 percent effective in preventing potential damage, according to Underwriters Laboratories (UL).

Install surge protection devices. Lightning strikes on or near a power line or utility service are a frequent cause of power surges. Point-of-use surge protection devices (SPDs), combined with a good grounding system, should protect your electronic and electrical appliances from most electrical surges. An SPD does not suppress or arrest a surge; it actually diverts the surge to the ground.
Service entrance SPDs provide protection for your entire electrical system and are usually installed at the electrical panel(s) or at the base of the service meter. These devices help prevent the entrance of overvoltages which can cause a fire. Surge protection devices are typically installed in conjunction with a lightning protection system.
Hire a professional. Installing a lightning protection system is not a do-it-yourself task due to all of the intricacies involved in completing the job accurately. Fortunately, you can find a reliable certified installer by visiting databases from the LPI and UL. โLPI certifies members in accordance with national safety standards,โ says VanSickle.
Seek certification. Make sure your professional installer uses only products that bear proof of UL certification. This ensures the equipment complies with national industry standards.
Get a second opinion. If you move into a home with a lightning protection system in place, or you have structural repairs done to your homeโs exterior that could compromise your current system, itโs wise to have your system checked out by a third-party independent follow-up inspector to ensure it still properly stands up to strikes.
Safeguard yourself. During a lightning storm, the inside of your home or office is the safest place to beโbut you still need to practice precaution, says VanSickle. Donโt touch anything that can conduct electricity, such as:
- Electrical appliances
- Metal surfaces, such as a sliding door
- Anything connected to your plumbing system
- Anything served by gas lines, such as water heaters, ovens, furnaces and fireplaces
Take action in an emergency. โLightning travels at 90,000 miles per second in air,โ says VanSickle. โThe time it spends on or in your home is measured in micro-seconds, so when you know youโve been struckโitโs gone.โ Following a damaging strike, VanSickle recommends inspecting the roof and attic areas to ensure there isnโt a fire above your smoke detectors. Then check utility rooms to see that there isnโt a problem with water, gas or electrical system components. โJust be aware that the lightning could have followed metal systems concealed in walls, the attic, under floors, etc., and there is a potential for a leak or a smoldering fire concealed from view,โ he says.
