Single-Ply Roofing in Jacksonville, FL | TPO, EPDM, PVC Installation

Service

TPO, EPDM, and PVC single-ply membranes are the standard commercial roofing specification across the Jacksonville metro. We install, recover, and repair all three systems — specified to ASCE 7-22 Duval County wind requirements and closed out with Florida Product Approval documentation and manufacturer warranty coordination.

Single-ply roofing — thermoplastic and thermoset membranes in 45-mil to 90-mil thickness, installed in a single layer — dominates commercial flat roofing installation in the Jacksonville metro. TPO has held the largest market share since the early 2000s. EPDM was the dominant system before TPO's market share grew. PVC serves specific applications where chemical resistance matters. The term 'single-ply' refers to the system architecture — one membrane layer, typically over an insulation assembly — rather than to any one material.

In Jacksonville's hurricane-exposure market, single-ply specification requires rigorous attention to the attachment system. ASCE 7-22 sets the design wind speed for Duval County Risk Category II buildings at 130 mph at 3-second gust — higher for coastal buildings in Exposure Category C and D, where buildings at NS Mayport, the barrier island corridors (Jacksonville Beach, Atlantic Beach, Neptune Beach), and within one mile of the Intracoastal Waterway face more aggressive calculated uplift pressures. The membrane itself has to perform in that wind environment; equally important, the insulation attachment, the edge-metal system, and the deck-to-membrane mechanical connection have to perform. Hurricane Matthew's 2016 Duval County track demonstrated that the membrane that fails first is often not the membrane that was in the worst condition — it is the membrane where the attachment system was undersized for the actual wind load.

We are manufacturer-agnostic across TPO, EPDM, and PVC. The right manufacturer for a given building depends on the warranty terms the owner requires, the Florida Product Approval status of the specific assembly, and whether the building owner's asset standard specifies a manufacturer. We recommend based on those criteria and document the selection rationale in the scope.

Single-Ply System Selection for Jacksonville Buildings

TPO is the default specification for most Jacksonville commercial new construction and replacement. White membrane meets Florida Energy Code's cool roof requirement directly. Heat-welded seams are strong and field-testable. 60-mil and 80-mil thickness options support 20- and 25-year manufacturer warranties. The installation is faster than EPDM on large-format warehouse and office buildings. Buildings in the JAXPORT logistics corridor, the Cecil Commerce Center industrial base, the Southside I-95 office park corridor, and the major healthcare campuses — UF Health on University Boulevard, Baptist Health at several Duval County locations, Mayo Clinic on San Pablo Road — are primarily TPO applications.

EPDM is specified when the building's use creates chemical or solvent exposure that TPO cannot tolerate, when the owner's portfolio standard specifies EPDM, or when recovery over an existing EPDM system with like-for-like material is the correct scope. EPDM's adhesive seam requires more quality-control attention than TPO's heat weld, but the fully adhered EPDM system provides superior wind-uplift performance in the highest coastal exposure categories. NAS Jacksonville facilities with fuel and chemical exposure in maintenance hangars, and industrial buildings in the Westside manufacturing corridor, are EPDM application cases.

PVC is specified for commercial kitchens, food processing, restaurant chain properties, and industrial buildings with specific chemical exposure profiles that PVC's formulation resists and EPDM does not. The Beach Boulevard restaurant corridor, the Town Center commercial strip, and food distribution facilities in the JAXPORT and Cecil Commerce Center areas are PVC application cases. PVC costs more per installed square than TPO but is the correct specification when the building's use demands its chemical resistance.

ASCE 7-22 and Florida Building Code Compliance in Jacksonville

Every single-ply installation in Jacksonville must be specified against ASCE 7-22 wind-uplift requirements for the building's location, exposure category, and risk category. Florida Building Code requires Florida Product Approval for every component of the roofing assembly — membrane, adhesive, fasteners, insulation, and edge-metal — not just for the membrane alone. We assemble the FL PA documentation for every project as part of the pre-construction submittal package and include it in the closeout package.

The High Velocity Hurricane Zone (HVHZ) — which mandates the strictest FBC wind requirements — applies to Miami-Dade and Broward Counties, not to Duval County. Jacksonville operates under standard FBC non-HVHZ wind requirements. The distinction matters for insulation product approval and fastener pull-through testing requirements. Our Duval County specifications meet FBC non-HVHZ requirements while accounting for the elevated coastal exposure that Jacksonville's Atlantic coast geography creates for buildings near NS Mayport, the barrier island communities, and the JAXPORT waterfront.
