Learn About Lightning Protection
Most people have never had lightning protection explained to them properly. This is where we do that — how the system works, what installing it involves, and what it looks like when it does its job.

What a Direct Strike Actually Looks Like
This is what a lightning protection system looks like after it has done its job. One of our technicians spotted a damaged air terminal from the street during a routine drive-by, went up to inspect it, and found a terminal that had taken a strike big enough to blow its sphere in half. In three minutes you will see exactly what a direct strike does, why the damage is invisible from the ground, and why we inspect systems every year.

The process
From First Call to a Certified System
Four steps. No surprises, and no charge until you have seen the design.
Free Risk Survey & Design
We walk your property, assess how lightning could reach it, and design a system around your roof and architecture — at no charge. You get a plan before you get a price.
Ground Testing
Before anything goes on the roof, we measure what is under it. Florida sand is a poor conductor, so we test soil resistivity and design the earthing system around the result.
Installation
Licensed electricians and certified installers fit the air terminal, down conductors, grounding, and surge protection to HBP-21 Level II — typically with no more than two roof penetrations.
Certification & Inspection
We document the installation, register it with the manufacturer, and inspect it annually — because strike damage is not something you can see from the ground.

From our customers
Why Homeowners Trust the System
“Living on the water in Florida, storms are a way of life. Since the Preventor system went on our roof we've stopped worrying every time the sky turns dark — and our electronics have survived seasons that took out neighbors' equipment.”
