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.
A complete system also includes surge protection, because lightning can damage your electrical system even when it strikes a nearby power line or tree instead of your house.
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 traveling 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?
- Is surge protection included?
- 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.
