The short answer

Signs of a Lightning Strike

Lightning can hit your home directly or indirectly through nearby strikes. Direct hits often leave visible marks: scorched roofing, shattered chimney bricks, or splintered wood. Indirect strikes travel through wiring and plumbing, so you might not see damage at the point of entry.

Check your attic and roof for charred spots or melted metal on vents, antennas, or gutters. Inside, look for soot around outlets, switches, or your electrical panel. A strong burnt odor that lingers in a room can also signal a strike, even if you cannot see a mark.

  • Scorch marks on roofing or siding
  • Cracked or displaced chimney bricks
  • Melted metal on roof fixtures
  • Burnt smell near electrical outlets
  • Tripped circuit breakers or blown fuses
  • Dead or flickering lights

Check Your Electrical System

A lightning strike can send a powerful surge through your home's wiring, frying electronics and appliances. If you notice that your TV, computer, or refrigerator stopped working after a storm, that is a strong clue. Also, check for any warm or discolored outlets, which can indicate heat damage.

Your electrical panel may show signs of a surge, like a tripped main breaker or burn marks around the breakers. If you see any of these, turn off power to the affected circuits and call an electrician to inspect the system. Do not attempt to fix wiring yourself.

Look for Water Damage

Lightning can create holes in your roof or walls, letting rain pour in before you notice. Check your attic, ceilings, and walls for fresh water stains, damp insulation, or dripping water. A strike can also damage your gutters or downspouts, causing water to pool around your foundation.

If you find water damage, act quickly to prevent mold and structural issues. Move furniture away from wet areas, place buckets under leaks, and dry out the space with fans if possible. For significant water intrusion, local water damage pros can assess the extent and help with cleanup.

Inspect for Fire Damage

Lightning can ignite fires in your attic, walls, or even inside electrical wiring. Look for black soot on surfaces, charred wood, or a smoky smell that persists. If you suspect a fire, even a small one, call your local fire department immediately. Do not enter a room where you see active flames or heavy smoke.

Fire suppression efforts, like sprinklers or fire hoses, can cause water damage even if the fire is small. After the fire is out, check for water-soaked drywall, carpets, and insulation. These materials may need to be removed to prevent mold growth, and a water damage inspection can help determine what is salvageable.

When to Call the Pros

If you see any signs of a lightning strike, it is wise to have a professional inspection. The pros can identify hidden moisture, evaluate structural damage, and help you decide what repairs are necessary. They can also check for mold, which can develop within 24 to 48 hours after water exposure.

An inspection can also document the damage for your insurance claim. Policies vary, and your insurer decides what is covered. Take photos of all damage, keep receipts for any temporary repairs, and contact your insurance company to report the incident. They will guide you on next steps.

  • Do not touch downed power lines or damaged electrical panels
  • Avoid walking through standing water if you suspect electrical hazards
  • See a doctor if you feel unwell after a lightning event
  • Keep a fire extinguisher handy during storms
  • Document damage with photos for your records
