The short answer

How Lightning Reaches Your Home

Lightning typically strikes the tallest object in an area, which is often a tree, utility pole, or the roof of a house. But a strike doesn't have to hit your roof to affect your home. The electrical current can travel through the ground, power lines, cable lines, or metal plumbing pipes and enter your house from there.

For example, a strike to a nearby tree can send a surge through the soil and into your home's grounding system. That surge can then jump to electrical outlets, appliances, or water pipes. So even if your roof is untouched, the lightning can still cause significant damage inside your walls, attic, or basement.

Signs of Lightning Damage Beyond the Roof

If lightning strikes nearby, you might notice blown fuses, tripped breakers, or damaged electronics. Look for scorch marks on outlets, a burnt smell near electrical panels, or cracks in concrete floors where the current traveled through rebar. Water pipes can also suffer damage, leading to leaks that cause hidden water damage.

Check your attic and crawl spaces for signs of moisture or unusual odors. Lightning can cause tiny pinhole leaks in metal pipes or damage the rubber seals around plumbing fixtures. These leaks might not show up right away, so it pays to inspect areas where water could pool, like under sinks, near water heaters, or along basement walls.

What to Do After a Nearby Strike

If you suspect lightning hit close to your home, start by checking for immediate hazards. Turn off appliances and electronics that might have been affected, and avoid touching metal pipes or wet surfaces until you are sure it is safe. If you smell gas or see sparks, leave the house and call emergency services from a safe distance.

Once you confirm it is safe, take a walk around your property. Look for damaged trees, downed branches, or scorch marks on the ground. Check your roof for missing shingles or holes, and inspect your gutters for debris that might have been knocked loose. Document any visible damage with photos for your insurance records.

You can reduce the risk of lightning damage by installing surge protectors for your electronics and ensuring your home's grounding system is up to date. An electrician can check your grounding and recommend improvements, which may help divert surges safely. Also, keep trees trimmed so they don't overhang your roof, as a struck branch can fall and cause roof damage.

For plumbing, consider insulating metal pipes, especially in older homes. While you can't stop lightning from striking, you can limit the damage it causes. If your home does suffer water damage from a lightning-induced leak, quick action is key. Drying wet areas within a day or two helps prevent mold and structural issues.

When to Call the Pros

If you discover water stains, damp drywall, or a musty smell after a lightning storm, it's time to get professional help. Water damage can hide behind walls and under floors, and without proper drying, mold can develop within days. Local water damage pros have the equipment to detect moisture and dry affected areas thoroughly.

They can also address secondary issues like damaged drywall or flooring that needs removal. For roof damage from a falling branch or a strike, emergency roof tarping can protect your home until repairs are made. If you live in Bellingham, keep your shutoff valve location written down and act quickly if you suspect a leak.

  • Visible water stains on ceilings or walls
  • Wet insulation in the attic
  • Warped or buckled flooring
  • Musty odors in any room
  • Unexplained increase in your water bill

Understanding Insurance and Claims

If lightning causes water damage, your insurance policy may cover the repairs, but it depends on the specifics of your coverage. Policies vary, and your insurer decides what is covered. Document all damage with photos and keep receipts for any temporary repairs you make, like tarping a roof or moving wet furniture.

Contact your insurance company as soon as possible to report the claim. They will likely send an adjuster to assess the damage. While you wait, you can start the cleanup process, but avoid throwing away damaged items until the adjuster has seen them. This helps ensure you get the full consideration for your losses.

Yes, lightning can strike the ground and the current can travel through the soil into your home's plumbing or electrical system. This can cause damage to outlets, pipes, and appliances even if the strike is several feet away.

What are the first signs of lightning damage inside a house?

Look for tripped breakers, blown fuses, or a burnt smell near outlets. Also check for cracks in walls or concrete, and any new water stains, which could indicate a pipe damaged by the electrical surge.

Should I have my home inspected after a nearby lightning strike?

If you notice any signs of damage or even if you're unsure, it's wise to have a professional check. Water damage can be hidden, and an inspection can catch issues early, preventing costly repairs and mold growth.
