Large-scale flat roof systems — TPO, EPDM, modified bitumen — are the defining exposure on industrial and warehouse properties. When hail, wind, or a mechanical failure compromises a 200,000 square foot membrane, the carrier’s adjuster will attempt to scope the damage as isolated penetrations or localized repairs. That approach ignores the systemic nature of membrane failures: granule loss across the full field, compromised seams, flashing breaches, and the accelerated deterioration that follows the initial event.

Code upgrade requirements represent a second category of recovery that carriers routinely exclude from initial estimates. A roof system that was installed under the 2006 building code cannot be replaced under the 2024 building code without triggering mandatory upgrades — vapor barriers, insulation R-values, drainage standards, parapet heights. Ordinance or Law coverage exists precisely for this exposure, and it is almost universally underclaimed on industrial properties because the carrier’s adjuster doesn’t build it into the scope.

Mechanical and HVAC damage at industrial scale is a third front. Rooftop units, exhaust systems, condenser arrays, and process equipment damaged by the same event that damaged the structure are covered losses. Carriers separate these line items, argue that equipment damage falls under equipment breakdown rather than property, and rely on policyholders accepting that distinction. We don’t accept it. We document the event, establish causation, and recover every dollar the policy supports.
