Commercial Re-Roofing for commercial buildings across Jacksonville.
TPO (thermoplastic polyolefin) is the workhorse single-ply membrane for Jacksonville commercial flat roofs. It reflects solar heat — important in a market where summer roof surface temperatures exceed 160°F — welds reliably with hot-air seam tools, holds up against UV degradation, and carries 20-year manufacturer NDL warranty paths from every major manufacturer (GAF, Carlisle, Johns Manville, Sika Sarnafil, Versico, Firestone).
We install TPO mechanically attached, fully adhered, or ballasted depending on building use, wind exposure zone, and the manufacturer's Florida-specific design package. Most Jacksonville commercial TPO work is mechanically attached on tapered ISO over metal deck, using fastener patterns designed against ASCE 7-22 wind-uplift requirements for Duval County's design wind speed. Buildings within one mile of the Atlantic coast or Intracoastal Waterway operate under higher wind-exposure categories and require more aggressive fastener density and Florida Product Approval-qualified edge-metal systems.
TPO Membrane Thickness: 60-mil vs 80-mil in Jacksonville Conditions
60-mil TPO is the standard commercial specification in the Jacksonville market — adequate for warehouse, retail, office, and light-industrial buildings with normal foot traffic and standard rooftop equipment. It carries a 20-year manufacturer NDL warranty from every major manufacturer and meets Florida Building Code requirements for this region with appropriate fastener patterns.
80-mil TPO costs more per square foot installed but provides extended warranty life (up to 25 years from some manufacturers), better puncture resistance for high-traffic rooftops, and additional thickness buffer against the thermal cycling that comes with Jacksonville's high solar radiation. We specify 80-mil for buildings near medical campuses (UF Health, Baptist Health System, Mayo Clinic Jacksonville) where rooftop mechanical access is frequent, for industrial facilities with heavy equipment or high foot traffic, and for owners who prioritize lower lifecycle cost over lower upfront cost.
Attachment Methods for Jacksonville's Wind Exposure
Mechanically attached: Most common in the Jacksonville market. Membrane fastened with screws and plates through the membrane and insulation into the deck on a pattern designed against the building's specific wind-uplift requirement. Cost-effective and fast to install. The fastener pattern must be tighter at roof perimeters and corners than in the field — Florida Building Code and ASCE 7-22 are explicit on the zone-by-zone requirements.
Fully adhered: Membrane bonded to the substrate with a TPO-compatible adhesive. Used when the project needs the cleanest aesthetic, when the deck cannot accept additional penetrations (certain lightweight concrete decks), when wind-uplift requirements exceed what mechanical attachment delivers, or when the building is in a coastal high-wind zone where the design engineer specifies full adhesion. Fully adhered systems also perform better in high-humidity conditions because there is no fastener-point moisture path.
Induction-welded fastening: A hybrid approach using special fasteners beneath the membrane that are activated by an induction-welding tool without penetrating the membrane face. Used on buildings where the owner wants mechanical attachment performance without exposed fasteners telegraphing through the membrane. Less common but available for projects that specify it.
