What Happens to a House When Lightning Strikes It?

Right after a strike, check for visible signs of fire, especially in the attic, behind walls, and around electrical panels. Smoke or a burning smell means you should leave the house and call the fire department. Also look for cracked bricks, displaced roof tiles, or shattered windows from the pressure wave.

Water damage often follows a strike because the lightning can puncture the roof or damage gutters, letting rain inside. Inspect ceilings and walls for dark spots, peeling paint, or sagging drywall. If you find water, turn off the electricity at the breaker if it is safe to do so, and start drying the area to prevent mold.

• Check attic and crawl spaces for smoke or charring
• Look for cracked chimney bricks or loose flashing
• Inspect windows for cracks from the pressure wave
• Feel walls for warmth that may indicate hidden fire
• Note any wet spots on ceilings or near outlets

Lightning can travel through metal pipes, causing pinhole leaks or cracking joints. Check under sinks, around water heaters, and along exposed pipes for drips or wet spots. A sudden leak can lead to water damage in floors, walls, and cabinets, so address any moisture quickly.

Gas lines can also carry the surge, potentially damaging valves or causing small leaks. If you smell gas, leave the home and call the gas utility from outside. Do not turn on lights or use any switches. After a strike, a plumber can test your pipes for damage and ensure everything is safe.

If you see fire, smoke, or smell burning, call emergency services first. Once it is safe, contact local water damage pros to assess any water intrusion from roof or pipe damage. They can dry out affected areas, remove soaked materials, and prevent mold growth before it spreads.

Also have an electrician check your wiring and a plumber inspect your pipes, even if you see no obvious problems. Document all damage with photos and notes for your insurance claim. Policies vary, and your insurer decides what is covered. Keep records of any repairs and temporary fixes you make.
