A homeowner in Riverside with a flat-roofed garage addition and a facility manager overseeing a 15,000 square foot warehouse in Westside both called about single ply roofing the same week. Both got quotes for TPO membrane. The numbers looked nothing alike, and the reason wasn’t the material, it was the scale and complexity of each project.
How much does single ply roofing cost in Jacksonville in 2026? A small residential flat-roof section, like a garage or addition, typically costs $2,500 to $8,000 installed, while a full commercial single ply roof runs $25,000 to $150,000 or more depending on building size. The per-square-foot rate is similar across both, but project scale, access, and complexity create very different total costs.
Devore Capital Roofing installs single ply roofing for both residential flat-roof sections and full commercial buildings across Duval County and the surrounding Northeast Florida region. This article breaks down what drives the cost difference between the two so you can budget accurately for your specific project.
This article compares single ply roofing costs between residential and commercial applications in Jacksonville, explaining why the per-square-foot rate stays similar while total project costs differ significantly. It covers what drives commercial costs higher and what residential homeowners should expect for smaller flat-roof sections.
This guide helps homeowners with a flat-roof addition, garage, or porch cover, as well as commercial property owners and facility managers, who want realistic single ply roofing cost expectations for their specific project type.
Single ply roofing, including TPO, EPDM, and PVC membranes, costs $5.00 to $11.00 per square foot installed in Jacksonville, regardless of whether the project is residential or commercial. This per-square-foot rate reflects the membrane material, seaming labor, and standard installation components.
TPO typically falls in the middle of this range, EPDM often costs slightly less, and PVC tends toward the higher end due to its stronger chemical resistance and heat-welded seam technology. This rate holds fairly steady across project types, which is why total cost differences between residential and commercial projects come down almost entirely to size and complexity rather than a different pricing structure.
A residential single ply roofing project, typically covering a flat-roof addition, garage, or covered porch, generally costs $2,500 to $8,000 total in Jacksonville. These sections are usually a few hundred to under 1,500 square feet, which keeps the total project cost well below a full commercial installation.
Residential projects also tend to have simpler access requirements, since most homes don’t need the specialized equipment or staging that larger commercial roofs require. This helps keep labor costs proportionally lower on a per-project basis even though the per-square-foot rate is similar.
A full commercial single ply roofing installation typically costs $25,000 to $150,000 or more in Jacksonville, depending on the building’s total square footage. A small commercial building under 5,000 square feet falls toward the lower end, while a large warehouse or distribution facility can reach well into six figures.
Commercial projects frequently include additional cost components that residential projects rarely need, including tapered insulation for proper drainage, upgraded flashing at rooftop equipment penetrations, and staging or lift equipment for buildings with limited ground access. These additions can meaningfully increase the total cost beyond the base membrane installation price.
Beyond scale, a few shared factors move single ply roofing cost up or down regardless of whether the project is residential or commercial. Existing roof condition matters significantly, since deck repair discovered during tear-off adds cost on both project types.
Insulation requirements add cost on commercial roofs more often than residential ones, since larger buildings frequently need tapered insulation systems for proper drainage that a small residential flat section typically doesn’t require. Rooftop equipment, like HVAC units common on commercial buildings, adds flashing and detail work around each penetration. Membrane type shifts cost modestly within the per-square-foot range, with PVC generally costing more than EPDM for the same square footage.
Hiring a licensed, GAF-certified contractor for single ply installation protects the investment on both residential and commercial projects. Seam welding quality, in particular, determines whether a single ply roof reaches its full 15 to 30 year expected lifespan or fails prematurely from water intrusion at poorly sealed seams.
Delaying a needed single ply roof replacement, or hiring an unqualified installer to save money on either a small residential section or a large commercial roof, tends to cost more over time. A single ply roof with early seam or flashing problems is at higher risk during Northeast Florida’s June through November hurricane season, and the resulting water damage often costs far more than the original installation savings.

Q: How much does single ply roofing cost per square foot in Jacksonville?
A: Single ply roofing, including TPO, EPDM, and PVC, costs $5.00 to $11.00 per square foot installed in Jacksonville, with the rate staying similar across both residential and commercial applications.
Q: How much does a small residential flat roof cost with single ply membrane?
A: A residential single ply project, such as a garage or addition flat-roof section, typically costs $2,500 to $8,000 total, depending on the section’s size and condition.
Q: Why do commercial single ply roofs cost so much more than residential ones?
A: Commercial roofs cover far more square footage and often require additional components like tapered insulation, equipment flashing, and staging or lift access that small residential sections typically don’t need.
Q: Which single ply membrane is the most affordable option?
A: EPDM is typically the most affordable single ply membrane, while PVC tends to cost more due to its stronger chemical resistance and heat-welded seam technology.
Q: Does deck condition affect single ply roofing cost?
A: Yes. Deck repair discovered during tear-off adds cost on both residential and commercial single ply projects, regardless of the membrane type chosen.
Q: Do commercial single ply roofs need insulation as part of the installation?
A: Often, yes. Many commercial single ply roofs require tapered insulation systems for proper drainage, which adds cost beyond the base membrane installation price.
Q: Is single ply roofing a good option for a residential flat-roof addition?
A: Yes. Single ply membranes like TPO and EPDM work well for residential flat-roof sections, offering durability and waterproofing performance suited to Florida’s climate at a reasonable cost for smaller applications.
Single ply roofing costs a similar amount per square foot whether the project is residential or commercial, but total project costs diverge significantly based on scale, insulation needs, and access requirements. A small residential flat-roof section runs a few thousand dollars, while a full commercial installation can reach well into six figures depending on building size.
