The Versico roofing membrane line is a commercial single-ply system made by Carlisle Construction Materials, covering TPO, EPDM, and PVC membranes for low-slope buildings. If you are weighing Versico against Carlisle SynTec, Elevate (formerly Firestone), or GAF, the detail almost every review skips is the one that matters most: Versico and Carlisle SynTec are sister brands under the same parent, built on the same chemistry in the same plants, sold through a different channel. This review lays out the product lines, thicknesses, warranty tiers, published pricing context, and where each system fits, so a building owner or specifier can decide with facts instead of a sales pitch.
This assessment is based on Versico’s published technical data and warranty documentation plus aggregated contractor sentiment from roofing forums and industry write-ups. We did not lab-test these membranes. Where numbers vary by project, we say so.
Who makes the Versico roofing membrane, and is it the same as Carlisle?
Versico is a division of Carlisle Construction Materials, a subsidiary of Carlisle Companies, and it ranks among the top three single-ply manufacturers in the United States. Versico and Carlisle SynTec share manufacturing facilities and membrane chemistry: contractors consistently report that the two brands run off the same lines and differ mainly by distribution channel and contract pricing, not by performance. Versico typically reaches contractors through two-step distribution, while Carlisle SynTec sells more directly.
The practical takeaway: comparing “Versico vs Carlisle” is largely a channel and pricing question, not a materials question. A VersiWeld TPO roof and a Carlisle Sure-Weld TPO roof are built from closely related formulations. For a wider map of low-slope options, see our overview of the types of commercial roofing and how single-ply roofing systems (TPO, EPDM, PVC) compare.
Versico membrane lines at a glance
Versico sells three membrane chemistries under distinct brand names: VersiWeld (TPO), VersiGard (EPDM), and VersiFlex (PVC), plus fleece-backed VersiFleece versions of each. The table below summarizes the published thickness options, reinforcement, and warranty ceilings for each line. Pricing is shown as a reported contractor range for context and moves with region, deck condition, attachment method, and job size.
| Line | Chemistry | Common thicknesses | Attachment | Max total-system warranty | Reported installed cost (per square, 60-mil) |
|---|---|---|---|---|---|
| VersiWeld | TPO (thermoplastic) | 45, 60, 80 mil (100 to 135 mil in fleece-back and QA variants) | Mechanically attached, fully adhered, QA (factory-applied adhesive) | 30 years | Roughly $150 to $210, varies by project |
| VersiGard | EPDM (rubber) | 45 (ballasted), 60, 90 mil | Ballasted, mechanically attached, fully adhered, QA | 30 years (40-year non-prorated material option on 90-mil non-reinforced) | Roughly $130 to $190, varies by project |
| VersiFlex | PVC (KEE HP available) | 50, 60, 80 mil | Mechanically attached, fully adhered | 30 years | Roughly $170 to $230, varies by project |
Thicknesses and warranty terms are from Versico’s published spec and warranty submittal sheets. Cost ranges are aggregated from contractor-reported figures and are not manufacturer list prices.
VersiWeld TPO: the volume seller
VersiWeld is Versico’s reinforced TPO membrane, heat-welded at the seams and built with the OctaGuard XT weathering package for resistance to UV and heat aging. It comes in 45, 60, and 80 mil, with sheet widths up to 12 feet to cut seam count on large roofs. White VersiWeld is CRRC-rated for reflectivity and carries a 10-year reflectivity warranty on top of the system warranty.
Three install formats exist: mechanically attached for speed on new decks, fully adhered for wind uplift performance, and VersiWeld QA with factory-applied adhesive to shorten labor. VersiWeld Plus is the thicker-ply option for higher puncture resistance. For how mil thickness drives price, see our breakdown of TPO cost per square by mil.
VersiGard EPDM: longevity and cold-climate track record
VersiGard is Versico’s EPDM (rubber) membrane, sold in reinforced and non-reinforced sheets at 45, 60, and 90 mil. EPDM has the longest field track record of any single-ply chemistry and handles thermal cycling and cold climates well. VersiGard White adds CRRC-certified reflectivity for buildings that need a cool roof but prefer rubber over TPO.
The standout is warranty depth: 90-mil non-reinforced VersiGard White and Black qualify for a 40-year non-prorated material warranty, longer than most TPO or PVC options on the market. Ballasted 60-mil non-reinforced EPDM can reach a 30-year total-system warranty. For rubber pricing detail, see our guide to EPDM membrane pricing.
VersiFlex PVC: chemical and grease resistance
VersiFlex is Versico’s PVC membrane, offered in standard, FRS (fiberglass-reinforced scrim for dimensional stability), and KEE HP versions. KEE HP uses a high-molecular-weight plasticizer that resists migration, so the membrane keeps its flexibility and weldability longer, including in cold temperatures. VersiFlex is the pick for restaurants, hospitals, and any roof exposed to grease, oils, or chemical fumes that degrade TPO.
Thicknesses run 50, 60, and 80 mil, with white, tan, and light gray CRRC-certified options. PVC costs more per square than TPO or EPDM, but its weldable seams and chemical resistance justify the premium on kitchen-exhaust and industrial roofs.
Warranty options: what Versico actually covers
Versico offers total-system warranties from 5 to 30 years depending on membrane, thickness, and attachment, with a 40-year non-prorated material warranty available on 90-mil non-reinforced VersiGard EPDM. Total-system warranties cover both membrane and installation labor when applied by an authorized contractor, which is a stronger position than a material-only warranty.
Optional puncture and hail riders (1-inch and 2-inch hail sizes) can be added on qualifying membranes, useful in hail-prone regions. Coverage terms, exclusions, and inspection requirements vary, so read the submittal sheet for the exact system you are specifying. Our commercial roof warranty guide explains how total-system and material warranties differ in practice.
Versico pricing: what building owners can expect
Installed Versico cost depends on membrane, thickness, attachment method, deck condition, and market, so treat any single number with caution. As a rough guide from contractor-reported figures, a 60-mil TPO system often lands near $150 to $210 per square (100 square feet), EPDM slightly lower, and PVC higher. Versico frequently prices competitively with Carlisle SynTec and, per some contractors, at a better contract price for the same chemistry.
Because Versico moves through distributors, local availability and quoted price can swing with your distributor relationship. Always get line-item bids that separate membrane, insulation, fasteners, and labor so you can compare systems fairly.
Best for: who should choose Versico
Versico fits building owners and specifiers who want Carlisle-grade single-ply chemistry, often at a distributor-driven price, backed by one of the deepest warranty menus in commercial roofing. It is a strong default when your contractor already buys through a Versico distributor, when you want 40-year EPDM coverage, or when you need PVC with genuine chemical resistance.
It is less compelling if your installer is a factory-direct Carlisle SynTec applicator, since you would be buying near-identical material through a longer channel with no performance gain.
Pros and cons of Versico membranes
The short version: Versico gives you Carlisle-level materials and a broad warranty menu, but brand recognition and channel access lag its sister brand. Here is the balance.
- Pro: Same chemistry and plants as Carlisle SynTec, often at a competitive or better contract price.
- Pro: Full three-chemistry lineup (TPO, EPDM, PVC) plus fleece-backed versions from one manufacturer.
- Pro: Deep warranty menu, including a rare 40-year non-prorated EPDM material warranty and hail riders.
- Pro: Wide sheet widths (up to 12 feet) and QA factory-adhesive options that cut install labor.
- Con: Lower brand recognition than Carlisle, GAF, or Elevate with some building owners and lenders.
- Con: Availability and pricing depend on local distributor coverage, not factory-direct sales.
- Con: No independent performance edge over Carlisle SynTec, since the material is effectively the same.
Versico vs Carlisle, Elevate (Firestone), and GAF commercial single-ply
Against the major commercial single-ply brands, Versico competes on price and warranty depth rather than a unique performance claim. The table compares the four on the points that decide a spec. Durability findings come from third-party accelerated-aging write-ups, not our own testing.
| Brand | Parent | Channel | Max TPO warranty | Reported 60-mil TPO cost (per square) | Notable |
|---|---|---|---|---|---|
| Versico | Carlisle Construction Materials | Two-step distribution | 30 years | ~$150 to $210 | Carlisle chemistry, 40-yr EPDM option |
| Carlisle SynTec | Carlisle Construction Materials | More factory-direct | 30 years | ~$170 to $210 | Market share leader (Sure-Weld TPO) |
| Elevate (formerly Firestone) | Holcim | Distribution | 30 years | ~$165 to $200 | Claim caps commonly cited near $2M |
| GAF | Standard Industries | Distribution | 30 years | ~$185 to $225 | EverGuard Extreme strong in aging tests |
All four exceed the ASTM D6878 minimum standard for TPO. In one widely cited accelerated-aging comparison, GAF EverGuard Extreme led on heat-aging retention, with Carlisle (and by extension Versico chemistry) grouped mid-pack. For most buildings the installer’s skill and the attachment detail matter more than the brand badge. Compare the chemistries head to head in our single-ply roofing systems (TPO, EPDM, PVC) guide.
How we assessed Versico
This review draws on Versico’s published technical data bulletins and warranty submittal sheets for thicknesses, attachment methods, and warranty terms, plus aggregated contractor sentiment from roofing forums and industry articles for real-world pricing and performance impressions. We did not conduct laboratory or field testing of these membranes.
Cost figures are reported ranges from contractors and trade sources, not manufacturer list prices, and will differ by region, project size, and roof condition. Verify current specs and warranty language against Versico’s own documents before you specify a system.
Frequently asked questions
Is Versico the same as Carlisle? Versico and Carlisle SynTec are sister brands under Carlisle Construction Materials. They share manufacturing plants and membrane chemistry, so a VersiWeld TPO roof is closely equivalent to a Carlisle Sure-Weld TPO roof. The main differences are distribution channel and contract pricing, not membrane performance. Versico usually sells through two-step distribution, while Carlisle SynTec sells more directly.
Who makes Versico roofing membranes? Versico is a division of Carlisle Construction Materials, a subsidiary of Carlisle Companies, and ranks among the top three single-ply roofing manufacturers in the United States. It produces TPO (VersiWeld), EPDM (VersiGard), and PVC (VersiFlex) membranes, along with fleece-backed VersiFleece versions and a full line of insulation and accessories.
How long is the Versico warranty? Versico offers total-system warranties from 5 to 30 years depending on membrane, thickness, and attachment method. Its longest coverage is a 40-year non-prorated material warranty on 90-mil non-reinforced VersiGard White and Black EPDM. Optional 1-inch and 2-inch hail riders and puncture coverage can be added on qualifying systems. Total-system warranties cover both membrane and installation labor.
Is Versico TPO any good? VersiWeld TPO is a reinforced, heat-weldable membrane with the OctaGuard XT weathering package and meets or exceeds ASTM D6878. Because it shares chemistry with Carlisle Sure-Weld, its performance tracks the market leader. Independent accelerated-aging tests place Carlisle-family TPO mid-pack, with GAF EverGuard Extreme often leading, though installer quality typically matters more than brand.
How much does a Versico membrane roof cost? Installed cost varies with membrane, thickness, attachment, deck condition, and market. Contractor-reported figures often put 60-mil TPO near $150 to $210 per square (100 square feet), EPDM slightly lower, and PVC higher. These are aggregated ranges, not manufacturer list prices, so always get line-item bids that separate membrane, insulation, and labor.
What is the difference between VersiWeld, VersiGard, and VersiFlex? VersiWeld is Versico’s TPO (thermoplastic) membrane, VersiGard is its EPDM (rubber) membrane, and VersiFlex is its PVC membrane. TPO balances cost and reflectivity, EPDM offers the longest field track record and deepest warranty, and PVC resists grease and chemicals for restaurant and industrial roofs. All three offer multiple thicknesses and attachment methods.
