What Does Lightning Do to a Home It Strikes?

When lightning hits your roof, chimney, or a tall tree near your house, the electrical current seeks paths to the ground. It often travels through metal components like wiring, pipes, and structural steel. This can cause explosive damage, such as shattered concrete, blown-off roof tiles, or cracked chimneys. The heat from the strike can ignite wood, insulation, or other flammable materials, leading to a fire.

• Check for smoke or fire and evacuate if necessary
• Look for visible damage to the roof, walls, and windows
• Listen for hissing sounds that might indicate a gas leak
• Avoid touching electrical panels or wet areas
• Take photos of any damage for your records

Lightning can travel through metal water pipes, causing them to burst or crack. The sudden heat can expand the water inside, leading to leaks or even explosions. This can result in water spraying inside walls, damaging drywall, flooring, and personal belongings. You may not notice the damage right away, as it can be hidden behind walls or under floors.

If you suspect pipe damage, turn off your main water shutoff valve to prevent further flooding. Check for wet spots on ceilings, walls, or floors. Water damage can lead to mold growth within 24 to 48 hours, so you need to dry out the area quickly. Local water damage pros can assess the extent and help with cleanup and restoration.

• Turn off the main water valve if you suspect a leak
• Look for water stains on ceilings and walls
• Feel for dampness in carpets and flooring
• Remove wet items to a dry area if possible
• Use fans or dehumidifiers to speed drying

After a lightning strike, you need to act quickly but carefully. Document all damage with photos and notes. Contact your insurance company to report the incident, but remember that policies vary, and your insurer decides what is covered. Do not assume anything is covered until you speak with them.

If you have water damage, you may need to remove wet carpet, drywall, or flooring to prevent mold. Local water damage pros can handle this work, including drying and restoring your home. They can also help with inspection and cleanup. Keep your shutoff valve location written down so you can act fast in an emergency.

• Take photos of all damage, including electronics
• Make a list of damaged items for your insurance claim
• Contact your insurance company to start the process
• Hire a qualified electrician to check your wiring
• Call the pros if you have leaks or flooding
