What Happens if Lightning Strikes Your Roof?

Lightning Strikes Roof

Is it possible for your house to be struck by lightning? The answer is yes, and it’s more likely if your home is built on a hill or in a plain.

Since lightning attempts to find the shortest route from the clouds to the ground, it usually strikes the uppermost part of your home — the roof — and then a power surge or fire can result, affecting the roof, attic and the rest of your home.

While the chances of this happening are not necessarily high, there is a still a chance. And it doesn’t hurt to prepare. Make sure you know how to respond in order to minimize the damage to your home.

Risk of Power Surges

When lightning hits a home, electricity surges through its conductive systems on its way toward the ground, possibly affecting your plumbing and electrical wires.

If your house is struck by lightning, a power surge could ruin your valuable electronics, so unplug all of your expensive TVs and computers during a lightning storm.

Also, don’t take a shower or run any water during a storm. It could give you a dangerous electric shock if lightning strikes your house.

Risk of Fire Damage

One of the most at-risk areas of your house is its highest peak — the attic and roof. The heat from a lightning bolt can cause your attic insulation to ignite. Also, the power surge could set off sparks inside the walls, leading to a fire.

Call the Fire Department and Your Electrician

Call the fire department right away and evacuate if your home was struck by lightning and you smell smoke or see fire. Even if you see no signs of fire, you should still have the fire department come to your property and check — sometimes electrical fires begin inside the walls and aren’t evident until they grow.

You also should have a trusted electrician come to your home and see if the wiring was damaged. They can let you know if it’s safe or if wiring replacements are needed.

Get a Roofing Inspection Immediately

In many cases, homes that have been struck by lightning sustain significant roof and attic damage. The strike might open up a hole in your roof that may not be evident from ground level.

You shouldn’t climb onto your roof, especially when it may be weakened by structural damage. Instead, call an experienced roofer to come take a look and assess the extent of the damage.
