What Are the Signs That Lightning Struck Your Home?
Last updated October 26, 2026
The short answer
Visible Damage Inside
Look for scorch marks on outlets, switches, or the electrical panel. A lightning strike can travel through wiring and leave blackened spots or melted plastic. Check walls and ceilings for cracks or small holes where the current may have exited.
Electronics like TVs, computers, and appliances may stop working or show a burnt smell. Surge protectors can be blown out, and their indicator lights may be off. If you see any of these signs, do not touch the equipment until power is off.
- Scorch marks or soot near outlets
- Melted plastic or wire insulation
- Cracks in drywall or plaster
- Burnt smell that lingers
- Dead electronics or blown surge protectors
Signs on the Roof and Outside
Check the roof for missing shingles, charred spots, or a hole where lightning may have struck. Look at gutters and downspouts for damage, as the strike can travel through metal. Also inspect the chimney and any antennas for cracks or dislodging.
Trees near the house may have split bark or burnt limbs, which means the strike could have traveled underground to your foundation. Look for disturbed soil or cracks in the concrete slab. These clues help the pros identify the path of the strike.
Electrical and System Clues
Tripped breakers or blown fuses are common right after a strike. Your home may have partial power, with some rooms dark while others work. A burning smell near the panel is a warning to shut off the main breaker carefully.
Phone lines, cable, and internet may fail, even if the wiring looks fine. A strike can surge through these low-voltage lines and damage the equipment. If you smell smoke or see sparks, leave the house and call the fire department from a safe distance.
What to Do Right After
Turn off the main power if you can do so safely, and avoid touching wet surfaces or electronics. Call your insurance company to report the damage and ask about coverage. Policies vary, and your insurer decides what is covered.
Have a qualified electrician check the wiring before you turn power back on. If you see water damage, contact local water damage pros for an inspection. In Port St. Lucie, storm season brings frequent lightning, so it helps to know your risks ahead of time.

First, ensure everyone is safe and call the fire department if you see smoke or fire. Turn off the main power if possible. Then, document damage with photos and contact your insurance company. A professional can inspect electrical and structural systems.
How long does it take for water damage to appear after a lightning strike?
