The short answer
First Steps for Safety
If lightning hits your home, your first priority is safety. Look for signs of fire, such as smoke or a burning smell. If you see flames or suspect a fire, get everyone out and call the fire department right away. Do not re-enter until they say it is safe.
After the immediate danger passes, check for electrical issues. If you can safely reach your breaker box, turn off the main power to prevent surges or shorts. Also, turn off the main water supply if you notice leaks, as lightning can damage pipes. If you feel unwell, see a doctor.
Assess Water Damage
Lightning can cause water damage in several ways. A strike can crack pipes, rupture water heaters, or send surges through plumbing, leading to leaks. It can also damage your roof, allowing rainwater to enter. Look for wet spots on ceilings, walls, or floors, and check for dampness in your attic.
Water from a lightning strike may be contaminated if it comes from damaged pipes or sewage lines. Avoid touching standing water, especially if it is near electrical outlets. If you have significant water, local water damage pros can help with a thorough inspection and safe cleanup.
- Turn off power and water if safe
- Document damage with photos
- Check for hidden leaks in walls
- Look for roof damage from the strike
- Keep children and pets away from wet areas
Document for Insurance
Before any cleanup, take photos and videos of all damage. Include close-ups of cracks, wet spots, and any items affected. This documentation helps with your insurance claim. Policies vary, and your insurer decides what is covered.
Keep a list of damaged belongings and their approximate value. Do not throw away damaged items until your insurance adjuster has seen them, if possible. If you need to remove water-damaged flooring or drywall for safety, keep samples or photos for reference.
Call the Pros
Once you have documented the damage, contact the pros. They can inspect your home for hidden water damage, including in walls, ceilings, and insulation. Their work typically involves drying out affected areas and preventing mold growth.

Prevent Future Damage
After the immediate issue is handled, consider ways to reduce future risk. Install surge protectors for your electronics and appliances. Ensure your gutters and downspouts are clear to direct water away from your foundation.
Have a professional electrician check your wiring and grounding. A roofer can inspect for damage from the strike. These steps help protect your home, though they cannot prevent all future lightning events.

Can lightning cause water damage even if it doesn't rain?
Yes. Lightning can damage plumbing pipes, causing leaks even without rain. The electrical surge can crack pipes or damage water heaters. Check for damp spots or unexplained water bills after a strike.
Should I turn off my power after a lightning strike?
If it is safe to reach your breaker box, yes. Turning off the main power helps prevent electrical fires from surges. If you smell burning or see sparks, leave the house and call the fire department first.
What if I see smoke but no fire?
Treat smoke as a fire risk. Evacuate everyone and call the fire department. They can locate hidden fires in walls or attics. Do not re-enter until they give the all-clear.
