How Do I Know If Lightning Hit My House?

Check your roof, siding, and chimney for visible physical damage. Look for shattered shingles, scorch marks, or holes. Metal components like gutters or vents might have burn marks or be melted. Trees near your home may show a long vertical split or stripped bark. If you find any of these signs, keep a safe distance and document the damage with photos for your records.

Inspect the ground around your home's foundation for unusual disturbances. Lightning can create small craters or burn patches in the soil or landscaping. Check your outdoor electrical fixtures, such as security lights or outlets, for damage. These external clues often provide the first confirmation that a strike occurred and can point you toward where the main electrical entry point might be compromised.

Lightning can follow metal pipes, causing hidden damage to your plumbing system. You may notice pinhole leaks in pipes, especially where they are near electrical grounding rods. Faucets might deliver discolored water initially. In severe cases, the intense heat can crack or melt PVC pipes. In hot, dry climates, pipes can be under additional stress, making inspection after a storm wise.

The structural framing of your home can also be affected. Wood near the strike path can be splintered or charred. You might hear popping sounds from walls as materials cool. Drywall can show bubbling or cracks. Since water pipes and electrical wires often run through the same wall cavities, damage to one system frequently indicates problems with the other, requiring a thorough professional assessment.

A lightning strike can create small, hard-to-find leaks in your plumbing or roof. Water may seep into subfloors, walls, and ceilings slowly, leading to mold growth and structural rot over time. You might notice a musty smell, damp drywall, or warping floors days or weeks after the storm. In dry climates, such hidden moisture can go unnoticed until significant damage occurs.

Local water damage pros use tools like moisture meters and thermal imaging cameras to detect hidden water without invasive demolition. They can perform moisture mapping to find the full extent of wet areas. If leaks are found, services like structural drying and dehumidification are necessary to properly dry building materials and prevent secondary damage like mold, which requires a separate mold professional to address.
