Engineered protection for Florida warehouses, plants, retail, and offices
A lightning strike a quarter-mile away can send a surge into your electrical system, knock out equipment, corrupt data, damage inventory, and leave you liable for business interruption. For a manufacturing facility, retail center, warehouse, or office, that isn’t just a maintenance call — it’s a continuity event. You can’t wait for “ideal conditions” to install protection. You need it now.
All South Lightning Protection designs and installs engineered lightning protection and surge suppression systems for the buildings that power Florida commerce: warehouses and distribution centers, manufacturing and industrial plants, retail and commercial centers, office buildings, and hospitality facilities across the state. Every system is purpose-designed to NFPA 780 and UL 96A — not pulled off a shelf. We have done this, and only this, for 40 years.
Florida is the lightning capital of the United States, with roughly 1.4 million cloud-to-ground strikes a year. If your commercial building sits here, the question isn’t whether it gets exposed. It’s whether it’s protected when it does.
Most commercial property owners assume their building is fine because it has a roof, a grounding system, and a breaker panel. Those are necessary but not sufficient. A complete lightning protection system is a separate engineering discipline — and that’s where gaps get expensive. Here’s what’s actually at risk when a strike or nearby surge reaches an unprotected commercial facility:
Most facility managers believe they’re covered because the building has a ground and a breaker panel. That’s half the story. Use the layered model below to audit your own building top to bottom, the strike enters the same way every time, and a gap at any layer is the gap that gets used. Each layer lists what it does, the failure mode when it’s missing, and the standard it maps to.
| Layer | What it does | Failure mode if missing / undersized | Maps to |
|---|---|---|---|
| 1. Structural strike termination | Intercepts a direct strike at roof terminals and routes it to earth via down conductors, around the building. | Strike attaches to the roof, antenna, HVAC, or steel and arcs internally looking for ground — through your equipment and building. | NFPA 780 (Rolling Sphere Method) |
| 2. Service-entrance SPD (Type 1) | Clamps the large conducted surge on the utility feed before it enters the building’s main distribution. | Full service-entrance transient reaches panels and everything downstream — the biggest, most damaging pulse. | UL 1449 / NFPA 780 Ch. 4 |
| 3. Distribution SPD (Type 2) | Catches residual surge at panels feeding production, HVAC, security, and equipment circuits. | Let-through voltage still exceeds what machinery and controls can survive. | UL 1449 |
| 4. Equipment & data / signal line protection | Protects network, telecom, security, and control copper entering equipment rooms and control systems. | Transient bypasses all power-side protection — enters on data lines, the most-missed path. | NFPA 780 / IEC 62305 |
| 5. Grounding & equipotential bonding | Ties all conductive systems — roof, steel, pipes, equipment racks — to a common reference so nothing floats at a different potential. | Unequal grounds arc between each other — the classic source of “mystery” board failures and blown drives. | NFPA 780 / NEC Art. 250 |
| 6. Point-of-use equipment protection | Final trim at plug-load level, UPS outlets, and specialized equipment. | On its own it’s asked to absorb a service-entrance event it was never rated for, and fails. | UL 1449 (Type 3) |
| 7. Inspection & recertification cycle | Confirms the whole chain is intact after changes, additions, strikes, or building modifications. | Documentation lapses; a remodeled facility no longer matches its certified drawings. |
Commercial buyers don’t take “it’s protected” on faith — they require documentation. Every All South commercial system is engineered and installed to the standards below, and delivered with sealed, permit-ready drawings and a documented submittal package that satisfies code officials, insurers, and auditors.
| Standard | What it covers |
|---|---|
| NFPA 780 | Installation of lightning protection systems |
| UL 96A | Master Label requirements & inspection for LP systems |
| IEC 62305 | International lightning protection standard |
| LPI-175 / LPI-177 | Lightning Protection Institute design & installation certification |
| NEC Article 250 | Grounding and bonding requirements |
Is lightning protection required by code for commercial buildings in Florida?
NFPA 780 is the governing standard for lightning protection system design and installation, and many building codes, insurance carriers, and institutional clients require documented, code-compliant protection on commercial structures. We design every system to be permit-ready and fully documented for your AHJ and insurer.
How much does commercial lightning protection cost?
Cost depends on building size, complexity, and whether you’re retrofitting an occupied facility or installing a new one. We provide a site assessment and fixed estimate after we’ve evaluated your building and designed the system. Because cost depends entirely on the structure, we give you a real, fixed number for your building rather than a generic figure.
Can you retrofit an occupied building without shutting down operations?
Yes. We design installation sequences to minimize or eliminate downtime. Structural work (roof and down conductors) is largely external and can often run without occupancy impact. Electrical work is scheduled during off-hours or low-activity periods. You get a timeline with the quote so you can coordinate with your operations.
Do you protect just the structure, or the equipment and electronics inside?
Both. Structural lightning protection keeps a strike off the roof. But the real risk to your equipment comes from conducted surges on power and data lines — that’s why we install coordinated SPD (surge protective devices) from the service entrance through distribution panels to point-of-use. The two work together; the building protects the equipment, and the surge protection protects what’s plugged in.
Do you provide the documentation our insurer and compliance team need?
Yes. You receive sealed engineering drawings, a permit-ready submittal package, UL 96A certification, and a recertification schedule so your records stay audit-ready and compliant.
Can you protect a multi-building campus or industrial facility?
Yes. Multi-building sites are common — warehouses with adjacent admin buildings, manufacturing plants with separate utility structures, hospitality properties. We design a coordinated system across all structures, with unified grounding and bonding so the entire campus is protected as one installation. Each building gets assessed, engineered, and inspected within the master plan.
All South protects commercial and industrial facilities statewide from three Florida branches. Each office runs its own field crews, so you get local response backed by a single in-house engineering team.
