Lightning Struck My Chimney, Now What?

Has lightning struck your chimney? Your fireplace's chimney is usually your house's highest point, which is why it struck there. What does that mean? It means because a lightning bolt hit your chimney, it took heavy damage. It's estimated that a single lightning bolt has the electric equivalent of 200 lbs. of TNT. You may be thinking- that's all well and good; lightning struck my chimney, now what?

When Lightning Struck Your Chimney

If your chimney was just hit by lighting, look to see if any smoke is clearly visible or if there is a burning smell. Either indicates that your chimney is on fire; call 911 immediately. Inside masonry chimneys, an extremely flammable substance called creosote, generated when the wood is burned, can coat the inside of your chimney. If you don't have your chimney cleaned at least annually, there is a good chance your chimney is coated with creosote. A bolt of lightning will definitely set Creosote ablaze.

After a lightning strike, your chimney needs to be examined by competent chimney sweeps to estimate the extent of the damage.
