Yes, lightning can damage a roof. A direct strike usually hits the highest point of the house, which is often the chimney, a ridge vent or a metal flue, and it can blow bricks apart, burn through shingles and decking, or start a fire in the attic. Even a nearby strike can travel through wiring and plumbing. In Colorado Springs the practical answer is to know the signs, check from the ground and the attic, and have the roof inspected if anything looks wrong.
How lightning damages a roof
- Chimneys and masonry. The strike’s heat flashes moisture in brick and mortar to steam, which can crack a chimney stack or blow it apart. Loose bricks then fall onto the shingles.
- Shingles and decking. A strike can leave a scorched or blown-out hole, and the deck underneath may be charred even when the shingle surface looks small.
- Vents, flues and flashing. Metal roof penetrations are common entry points. Look for scorch marks, melted edges or flashing that has pulled away.
- Hidden fire. The National Weather Service notes that lightning travels through a building’s wiring and plumbing when the building is struck. Attic insulation and framing can smolder before anyone notices.
We saw the chimney version firsthand. After we finished a roof in Colorado Springs and left for the day, the homeowner called that evening to ask what had happened to her chimney. Lightning had struck the stack, and bricks were scattered across the new roof and the street.
What to check after a strike
- Call 911 first if you smell smoke, see scorching or have lost power to part of the house.
- Walk the yard. Look for brick, shingle pieces or metal debris, and look up at the chimney, ridge and vents.
- Check the attic with a flashlight once it is safe. Scorched wood, a burning smell, wet insulation or daylight through the deck all mean the roof needs attention.
- Photograph everything with the date and time, then call your insurance agent to ask how your policy treats lightning.
- Book an inspection so someone can check the chimney, flashing and deck up close. Our Colorado Springs storm damage repair team photographs each problem so nothing gets missed in the scope.
Lightning safety rules from the National Weather Service
The NWS lightning brochure is blunt: no place outside is safe when a thunderstorm is in the area.
- When thunder roars, go indoors. If you can hear thunder, lightning is close enough to strike you.
- Lightning may strike as far as 10 miles from any rainfall, so blue sky overhead does not mean you are safe.
- Wait at least 30 minutes after the last thunder before going back outside.
- Sheds, picnic shelters, tents and covered porches do not protect you. Fully enclosed buildings with wiring and plumbing are best, or a hard-topped metal vehicle with the windows closed.
- Indoors, stay off corded phones and away from plumbing during the storm. Cell and cordless phones are safe.
Why good roof crews stop at the first thunder
A roof is the worst place to be in a lightning storm, and a half-finished roof is exposed to the rain that follows. Our approach is to tear off only as much roofing as the crew can dry in quickly, so a fast-moving storm never catches the house open. Tarps are a last resort: a storm’s gust front can rip a tarp out of several people’s hands. When thunder starts, the crew gets off the roof and into a vehicle or the garage, and work resumes after the 30-minute wait.
That matters to you as the homeowner. If you are interviewing roofers, ask how they handle afternoon storms. A clear answer, such as limited tear-off and drying in each section the same day, tells you a lot about how they will protect your home. It is also why weather causes so many repair calls when it is ignored.
Protecting the house before the next storm
- Have the chimney checked for loose bricks and failed mortar. Damaged masonry is more likely to come apart.
- Ask about lightning protection if your home sits on a ridge or in open country such as Black Forest or Falcon. A lightning protection system is a specialty install by a qualified installer, separate from roofing.
- Keep flashing and vents sound. Our summer roof prep checklist covers the yearly checks.
Lightning usually arrives with hail and wind. If the same storm dropped hail, read what to check after a Colorado Springs hail storm, and if you are choosing a contractor afterward, see how storm roofing works and how to hire a storm roofer.
