How Do You Assess Lightning Damage to Your Home?

Last updated October 19, 2026

The short answer

Perform an Initial Safety Check

Before entering your home, ensure it is safe. Look for visible fire, smoke damage, or the smell of burning. Check that your main electrical panel has not been tripped or damaged. If you see sparks, exposed wires, or suspect a gas leak, leave immediately and call the utility company from a safe distance.

Once inside, use a flashlight if the power is out. Avoid touching any wet electrical components or standing water near outlets. Listen for unusual sounds like buzzing from your walls or appliances. This initial check helps you identify immediate dangers.

Inspect for Exterior and Structural Damage

Walk around your property to look for external damage. Lightning often strikes the highest point, so examine your roof, chimney, gutters, and siding for holes, charring, or missing sections. Check trees on your property for split trunks or large broken limbs that could fall. Damage to your roof or siding can create immediate openings for water intrusion.

Inspect your attic if it is safe to access. Look for signs of fire, such as scorched wood or insulation. Check for daylight coming through new holes in the roof decking. Even a small puncture can lead to significant water damage over time, especially during rain. Document all visible damage with photographs for your records.

Evaluate Your Electrical Systems and Appliances

Lightning surges can destroy wiring and electronics. Test your lights, outlets, and major appliances like your refrigerator or HVAC system. If any fail to turn on or behave erratically, the electrical surge may have damaged them. Do not repeatedly try to reset tripped breakers if they immediately trip again, as this indicates a fault.

Have an electrician inspect your home's wiring, electrical panel, and grounding system. They can identify compromised circuits that are not visibly damaged. This step is important because faulty wiring poses a serious fire risk. An electrician can also advise if you need to replace surge protectors or specific appliances.

  • Unplug sensitive electronics like computers and televisions.
  • Check your home's phone and cable lines for damage.
  • Test all ground fault circuit interrupter (GFCI) outlets.
  • Look for discolored or warm switch plates on walls.
  • Note any burning odors near outlets or the electrical panel.
  • Inspect your HVAC system's outdoor unit for physical damage.

Identify Hidden Water Damage and Moisture

Water often follows a lightning strike's path. Check ceilings, walls, and floors for new water stains, bubbling paint, or dampness. Feel for soft spots in drywall or flooring, which indicate trapped moisture. Pay close attention to areas below the attic or near exterior walls, as leaks may not be directly under the roof damage.

Use a moisture meter if you have one to detect elevated levels in building materials. Mold can begin growing within 24 to 48 hours in warm, humid conditions. If you find damp materials, they need to be dried quickly to prevent secondary damage. Water damage restoration pros have specialized equipment for this drying process.

Document Damage and Contact Your Insurance

Create a detailed record for your insurance claim. Take clear, date-stamped photographs and videos of all damage, both inside and out. Write a list of affected items, including descriptions and serial numbers for electronics. Keep receipts for any temporary repairs you make, like tarping a roof, as these costs may be reimbursable.

Contact your insurance company to start the claims process. Policies vary, and your insurer decides what is covered. Provide your documentation and follow their instructions. They may send an adjuster to inspect. You might need separate assessments from a roofer, electrician, or water damage restoration professional to support your claim.

  • Photograph structural holes, char marks, and damaged siding.
  • Record model numbers of malfunctioning appliances and electronics.
  • Save all correspondence with your insurance company.
  • Keep a log of dates and names of people you speak with.
  • Store damaged item samples, like a piece of burnt wood.
  • Note any temporary repairs made to prevent further damage.

Frequently asked questions

Can lightning damage cause a fire days later?

Yes, it can. A lightning strike can smolder within walls or attic insulation, igniting a fire hours or even days after the event. If you suspect a strike, monitor your home for several days for unusual heat or smoke smells. It is wise to have an electrician inspect hidden wiring.

What should I do if my electronics were on during a strike?

Unplug them immediately to prevent further surge damage. Do not plug them back in until your home's electrical system is checked by an electrician. Many may be permanently damaged by the power surge. Consider having a professional assess expensive electronics like computers or home theater systems.

Who should I call first after a lightning strike?

Call 911 if there is an active fire or gas leak. Otherwise, contact an electrician to check your electrical system. Then, call a roofer to address exterior damage and prevent water entry. For water intrusion and drying, local water damage pros can help prevent mold growth.
