What Hurricane Damage Looks Like on Orlando Commercial Flat Roofs

Perimeter and corner zone membrane uplift is the most common commercial flat roof hurricane failure mode in Central Florida. Florida Building Code wind-uplift requirements set the highest design pressures at the perimeter and corner zones of commercial roofs — the field zone center of a 30-foot building might see -30 psf design pressure while the corner zone sees -90 psf. When a mechanically attached TPO or EPDM system has inadequate fastener density at the perimeter and corner zones, Charley-magnitude wind loads pull the membrane up from the edge inward. We see this pattern on roofs where the original contractor used a field-zone fastener pattern uniformly across all zones — a code violation that passes visual inspection until the first major wind event.

Edge metal failure follows perimeter membrane uplift. FBC-required edge metal — the metal fascia and coping that secures the membrane at the building perimeter — must be tested to the ANSI/SPRI ES-1 standard for the wind exposure category. Edge metal that was not FBC-compliant at installation or was installed without proper mechanical attachment to the deck or parapet wall will separate from the building in sustained hurricane gusts, often taking a section of membrane with it. After Charley and Irma, a significant share of the commercial roof damage we documented was edge metal failure rather than membrane failure — the membrane performed fine; the metal that held it to the building did not.

Drain overload and ponding damage is the third major hurricane damage category, and the one most often missed in post-storm inspections. A building with a properly attached membrane can still experience interior damage from a storm if the roof drains cannot move hurricane-rainfall volumes fast enough. Orlando averages 3-5 inches of rainfall in a typical August or September tropical rain event; a major hurricane can produce 10-15 inches over 6-12 hours. If the drains are undersized, clogged with debris, or if the drain sumps have insufficient depression to keep water moving, the roof ponds. Ponded water pushes under membrane laps, penetrations, and flashing terminations and causes interior damage that looks — to an adjuster — like pre-existing neglect rather than storm damage.

How We Document Hurricane Damage for Insurance

Every hurricane damage inspection starts with a timestamped photo log tied to GPS coordinates. We photograph the roof before moving anything — drain covers that have blown off, edge metal that has separated, membrane that has lifted or torn, debris patterns that show wind direction and velocity at the building. The debris pattern itself is evidence: insulation fragments blown to the building's leeward side, drain covers moved from their locations, gravel carried from ballasted sections are all documentation of the wind event's effect on the building.

We then produce a roof zone diagram — a scaled plan of the roof with the damage locations marked — and a written scope of loss that distinguishes pre-existing deterioration from storm-related damage. Florida's property insurance environment, particularly after the assignment-of-benefits reform and the insurer consolidation of the post-Irma years, has become skeptical of claims that are not independently documented. An adjuster who receives a photo log, a zone diagram, and a written scope that separates pre-existing from event-related damage has something to defend a settlement on. An adjuster who receives a contractor's verbal estimate does not.

The written scope of loss we produce includes the repair specification — membrane patch or replacement, edge metal specification, flashing detail, drain inspection and cleaning or upsizing — with quantities, manufacturer product numbers, and FBC compliance notes. This scope goes to the building owner and, with their authorization, to the adjuster. We are available to walk the roof with the adjuster.

FBC Compliance in Hurricane Repair

Florida law requires that a hurricane repair that replaces more than 25% of a commercial roof's membrane area be brought into full Florida Building Code compliance — meaning if the original installation had inadequate fastener density, inadequate edge metal, or non-code-compliant flashing details, the repair must correct those conditions. This requirement is frequently misunderstood: some contractors repair only the visibly damaged sections and leave adjacent code deficiencies in place. The next storm then damages those sections, generating another claim.

Our hurricane repair scopes assess FBC compliance across the affected areas and adjacent zones. If we find perimeter fastener deficiencies adjacent to the storm-damaged sections, we document them and include them in the repair scope with a cost estimate. The owner decides whether to repair only the immediate storm damage or to bring the adjacent zones into compliance — but they make that decision with full documentation in hand, not after the next storm.
