UL-approved lightning protection for Coastal Bend buildings
Nelson Roof Contracting is a reliable contractor for UL-approved lightning protection systems. On the Texas Gulf Coast, where summer thunderstorms are frequent, a properly designed and installed system gives a strike a safe path to ground — and because we are roofers first, we install it without compromising your roof.
How a lightning protection system works
- Air terminals (lightning rods) are placed along the roof perimeter, ridges and high points to intercept a strike.
- Conductors — heavy copper or aluminum cables — connect the air terminals across the roof and run down the building.
- Grounding electrodes in the soil safely dissipate the lightning current into the earth.
- Bonding ties rooftop HVAC units, vents, railings and other metal into the system to help prevent side flashes.
- Surge protection at electrical service entrances is often part of a complete design.
Why a roofing contractor should install it
Every air-terminal base and conductor fastener touches the roof. On TPO, PVC and EPDM membranes, those attachments need compatible fittings and proper flashing or adhesion — otherwise the protection system becomes a leak. Because Nelson Roof Contracting installs the roof and the lightning protection, the two are designed together.
- Coordinated with new roofs and re-roofs — the cleanest time to install
- Membrane-compatible attachments so the roof stays watertight
- Re-installation of existing systems when a roof is replaced
- Periodic inspection and after-storm checks of terminals, conductors and connections
Buildings that benefit
Warehouses, churches and steeples, schools, offices, hotels and condos, industrial and port-area facilities, and any tall or isolated building on the coast.
Every rooftop detail supervised
Lightning protection, drains, flashings and seams all meet on the same roof. Every job is supervised and installed by our own in-house crews — no subcontractors.
Frequently asked questions
Do you install lightning protection systems?
Yes. Nelson Roof Contracting is a reliable contractor for UL-approved lightning protection systems for commercial buildings, and we coordinate them with roof work so the roof membrane is not compromised.
How does a lightning protection system work?
Air terminals (lightning rods) on the roof intercept a strike, conductor cables carry the current across the roof and down the building, and a grounding system safely dissipates it into the earth. Bonding ties nearby metal into the system.
Can lightning protection be installed on a TPO, PVC or EPDM roof?
Yes. Air terminals and conductors are attached with fittings designed for the membrane, and penetrations are flashed so the roof stays watertight. It is easiest to plan during a new roof or re-roof.
Does a lightning protection system need maintenance?
Yes. Systems should be inspected periodically and after roof work or major storms to check that air terminals, conductors, connections and grounding are intact.
