Lightning protection isn't required on most Texas homes, so whether to install it is a personal decision. The goal of this guide is to help you make that decision with clear information instead of fear. Here are the factors worth considering, what a system does and doesn't do, and what to ask a contractor.
What a lightning protection system does
A lightning protection system doesn't prevent lightning or attract it. If lightning strikes your home, the system gives the current a preferred place to attach (air terminals on the roof), a safe path around the house (conductors), and a way into the earth (grounding). Without that path, lightning current may travel through framing, wiring, plumbing, or gas lines, which is how strikes cause fires, structural damage, and destroyed electronics.
Factors that make a home more exposed
- Height and prominence. Two-story homes, homes with tall chimneys or towers, and homes that stand taller than the buildings and trees around them.
- Location. Homes on hilltops or ridgelines, such as in the Hill Country; homes on open land, like Panhandle and West Texas properties; and homes near open water.
- Isolation. Rural homes with few nearby structures, where the house and barn are the tallest things around.
- Regional storm patterns. Every part of Texas gets thunderstorms, from Gulf Coast summer storms to spring storms in North Texas and dry lightning in West Texas.
Reasons homeowners choose protection
- Reducing the risk of a lightning-caused fire in the attic or roof.
- Protecting expensive electronics, appliances, HVAC equipment, and home offices.
- Peace of mind when you're away or when storms roll through at night.
- Protecting a home that would be hard to replace, such as a historic, custom, or rural home far from a fire station.
What protection doesn't do
A system protects the structure it's installed on. It doesn't make it safe to be outdoors during a storm, and it doesn't protect people in the yard, animals in the pasture, or trees. When you hear thunder, go indoors.
Questions to ask before you buy
- Will the system be designed for my specific roof and soil?
- Does the design aim to follow recognized standards such as NFPA 780?
- How will conductors be routed, and how visible will they be?
- What happens to the system if I replace my roof?
- Can a third-party inspection or certification be arranged if I want one?
The bottom line
If your home is tall, isolated, on high ground, or full of equipment you'd hate to lose, lightning protection deserves a serious look. A free on-site estimate is the easiest way to see what a system would involve for your home. Learn more about residential lightning protection.
