How Lightning Burns Through Roof Materials Into the Attic

Lightning carries a massive electrical charge that seeks the fastest route to the ground. When it hits your roof, the current flows through conductive materials like metal flashing, gutters, or wet wood. The extreme heat, often hotter than the surface of the sun, can melt metal, char asphalt shingles, and split wood planks.

The burn is not always a clean hole. Sometimes the strike splinters the roof deck, cracks tiles, or vaporizes a small section of the membrane. In many cases, the damage is hidden from view until you go into the attic and see scorch marks, soot, or a faint glow.

• Melted metal flashing or gutters
• Charred or blistered shingles
• Cracked or shattered tiles
• Splintered wood decking
• Visible soot or smoke stains in the attic

Look for obvious damage from the ground, like a missing shingle, a dark burn mark, or a bent gutter. Inside, check the attic for blackened wood, a burnt smell, or small piles of ash. Also inspect the underside of the roof deck for scorch lines that follow the path of the current.

If you find damage, do not enter the attic if you see active flames or smell heavy smoke. Leave the home and call the fire department from outside. For less urgent damage, wait until the storm passes and then take photos for your insurance records.

First, ensure everyone is safe and the home is not on fire. If you see flames or smell gas, evacuate and call 911. Once the storm is over, document the damage with photos and notes, and contact your insurance company to ask about coverage for lightning and water damage. Policies vary, and your insurer decides what is covered.

For the roof repair, you may need a roofer to inspect and patch the hole. If water has already soaked into the attic insulation, drying it out quickly is key to preventing mold. Local water damage pros can remove standing water and dry the space, but you should act fast to limit secondary damage.
