Why manufacturer certification matters: Certification ensures accurate installation details and aligns your system with manufacturer requirements and warranty options, where applicable.
What is a TPO roofing membrane?
TPO stands for thermoplastic polyolefin. In commercial roofing, TPO is a single-ply membrane installed over insulation and a suitable roof deck, then sealed with heat-welded seams. Properly designed and installed, TPO is valued for energy performance, seam strength, and long-term durability.
Versico (a division of Carlisle Construction Materials/Carlyle) is a leading manufacturer of TPO membranes and systems, including reinforced membranes and complete assemblies.

Why “Versico Certified/Authorized Contractor” is important
Building owners often assume a warranty is “automatic.” It isn’t. Manufacturer warranty options can require installation by an authorized contractor, and higher coverage options may involve additional system requirements and inspection.
Here’s what this can mean for you:
- Single-source coverage options that can include materials and workmanship/labor for covered repairs.
- Total system / edge-to-edge concepts where components supplied by the manufacturer may be covered together (including certain edge metal options where specified).
- Inspection on completed installations for certain warranty types.
Translation: If your goal is maximum warranty confidence, it’s smart to choose a contractor who is legitimately qualified to install the system for the warranty you want.
Versico TPO membrane options: thickness, widths, and colors
TPO membranes are not “one size fits all.” Thickness and reinforcement matter. For example, Versico’s QA TPO reinforced membranes are commonly available in 60-mil and 80-mil thicknesses, with standard widths such as 10’ and 12’, and colors including white, gray, and tan.
What thickness should you choose?
- 60-mil: common for many commercial applications where budget and performance are balanced.
- 80-mil: often selected when owners want added robustness or when roof traffic/conditions justify it.
We’ll recommend the right assembly after an inspection—based on your roof’s condition, slope/drainage, penetrations, mechanical units, and how you use the building.
How TPO is installed (and why details matter)
TPO systems can be installed in different ways depending on the building, deck type, wind requirements, and design criteria. A common approach is insulation secured to the deck, membrane adhered or attached per specification, and seams hot-air welded.
Why seams and flashing determine real performance
The roof field is only part of the story. Most leaks start at transitions: drains, curbs, RTUs, skylights, parapet walls, and edge terminations.
That’s why we focus our inspections on the “failure zones” and build a scope that protects the building—not just the membrane.
Why many owners choose TPO over asphalt-based systems
When building owners compare TPO to modified bitumen or other asphalt-based systems, the deciding factors are often UV resistance, reflectivity, seam strategy, installation safety, and overall system simplicity. TPO is a single-ply membrane, and wider sheets can reduce the number of field seams compared to narrower roll goods.
Signs your TPO roof needs an inspection
- Active leaks, ceiling staining, or wet insulation indicators
- Wrinkles, open seams, or membrane shrinkage at details
- Ponding water, clogged drains, or deteriorated sealants
- Storm concerns: wind, hail, punctures from rooftop traffic
- You’re buying/selling a building and need a clear roof-condition report

TPO Roofing Membrane FAQs
How long does a TPO roof last?
Service life depends on membrane thickness, installation quality, rooftop traffic, drainage, and maintenance. A well-installed, well-maintained TPO system can provide long-term performance.
Your warranty options will depend on the complete assembly and qualification requirements.
Is TPO good for flat roofs in Idaho?
TPO is widely used on low-slope commercial roofs. In Idaho, the design details—drainage, edge securement, penetrations, and snow/ice considerations—are especially important.
We build systems to meet site conditions and applicable code/wind needs.
What’s the difference between 60-mil and 80-mil TPO?
Thickness impacts durability and robustness. Many owners choose 80-mil when they want added toughness or expect higher roof traffic, while 60-mil is common for many standard commercial applications.
Why does Versico authorization matter?
Certain manufacturer warranty options can require installation by a Versico Authorized Contractor and may include inspection and single-source coverage options depending on the warranty selected.
Can you repair a TPO roof instead of replacing it?
Often, yes—if the membrane is still serviceable and the issues are localized (seams, flashing, penetrations, drains, edge terminations). An inspection will determine the most cost-effective path.
