According to The National Severe Storms Laboratory, there are an estimated 100,000 thunderstorms each year in the U.S. alone. Because chimneys are the highest point of most homes, they are more susceptible to lightning strikes.
After lightning has struck your chimney, your first course of action should be to call the fire department. There may not be visible damage, but the strike could’ve caused a fire in the chimney that you cannot see. After the fire department, you should call a certified chimney sweep to schedule an inspection. Lightning strikes can cause a wide variety of damages that require repairs. A certified chimney sweep will let you know what the damages are, and what is necessary to fix them. If you wait to have your chimney inspected, any damages could fester and become a more pressing issue.
