The short answer

Ensure Immediate Safety and Check for Fire

After a lightning strike, your first priority is safety. Make sure all occupants are unharmed and safely away from any visible damage. Look for signs of fire like smoke, flames, or a strong burning odor. Check your attic, walls, and near electrical panels where fires can start unseen and spread quickly.

If you see or smell fire, evacuate immediately and call the fire department from a safe distance. Do not attempt to fight a large fire yourself. Once the area is confirmed safe, you can begin a more thorough inspection. Take care to avoid any standing water that could be electrified. Move cautiously and do not touch anything if you feel unsure.

Inspect Your Electrical System for Damage

Lightning can send a massive power surge through your home's wiring. Check your circuit breaker panel for tripped switches or signs of scorching. You may notice outlets that are discolored, warm to the touch, or making a buzzing sound. Appliances and electronics, especially those plugged in during the storm, could be internally damaged even if they look fine.

Unplug all non-essential electronics to prevent further damage from potential secondary surges. Have a qualified electrician inspect your system before restoring power to damaged areas. Faulty wiring poses a serious fire risk. This inspection is crucial for preventing future electrical problems in your home. It's a necessary step for long-term safety.

Look for Plumbing Leaks and Water Damage

A lightning strike's shock wave can crack pipes or damage water heater controls, leading to leaks. Water damage can start small but cause major structural issues if left unaddressed. In a hot, humid climate with rainy summers and a hurricane season, added moisture can accelerate mold growth behind walls. Quick action is essential.

If you find water, you need to stop the source. Locate your main water shutoff valve and turn it off. Then, contact local water damage pros to assess and dry the affected areas. Quick action helps prevent secondary damage like warped floors and mold.

  • Inspect ceilings and walls for new water stains or bulging.
  • Check under sinks, around toilets, and near your water heater for pooling water.
  • Look at exposed pipes in utility closets, attics, and crawlspaces for cracks or spraying.
  • Listen for the sound of running water inside walls when no faucets are on.
  • Feel flooring for unexpected dampness, especially near plumbing fixtures.
  • Examine your water meter; if it's moving with all water off, you likely have a leak.

Assess Structural Integrity and Roof Condition

Examine your home's exterior from a safe distance on the ground. Look for visible damage to the roof, such as missing shingles, cracked tiles, or a new hole. Check chimneys, siding, and gutters for cracks or sections that have been blown off. Structural damage from a direct strike can compromise your home's safety. Do not take risks to get a closer look.

Do not climb onto the roof yourself, as it may be unstable. Instead, take clear photos of any external damage for your records and for a professional assessment. A roofer can safely inspect for leaks and structural issues. This documentation is also vital for any insurance claim you might file.

Document Everything and Contact Your Insurer

Thorough documentation is key after a lightning incident. Take detailed photos and videos of all damage, including fire marks, electrical issues, water stains, and structural harm. Make a written list of damaged items and their approximate value. This creates a clear record for repair professionals.

Contact your insurance provider to report the incident and start the claims process. Policies vary, and your insurer decides what is covered. Be prepared to share your documentation. You may need separate estimates from an electrician, a roofer, and water damage restoration pros to fully repair your home. Keep all records organized for this process.

Frequently asked questions

Can lightning damage cause a fire days later?

Yes, hidden damage in wiring or within walls can smolder and ignite a fire later. If you suspect a lightning strike, have an electrician inspect your system even if you see no immediate flames. Ongoing strange smells or warm outlets are warning signs that require immediate professional attention.

What if my electronics were on during the strike?

Unplug them immediately to prevent further surge damage. Do not try to turn them on. Lightning surges can fry internal components even if the device appears normal. A qualified appliance repair specialist or electrician can assess if repairs are possible, but many electronics may be permanently damaged.

Who should I call for water damage from lightning?

For water from broken pipes or leaks, contact the pros. They can stop the water source, extract standing water, and dry the structure to prevent mold. You will likely also need a plumber to repair the physical pipe break that caused the flooding.
