Carlisle SynTec Systems is one of the manufacturers whose membrane product lines show up regularly on the commercial roofs we work on around Evansville. The company has been producing single-ply roofing membrane for decades and covers TPO, EPDM, and PVC under one roof, which gives us flexibility when a project calls for a specific membrane type.
Carlisle's Sure-Weld line is their TPO product, available in the standard thickness range including 45, 60, and 80 mil, in reflective white and other color options. It uses heat-welded seam technology standard to the TPO category, and Carlisle offers both mechanically attached and fully adhered installation methods depending on the roof deck and wind uplift requirements of the project. We spec Sure-Weld on reroofing and new construction jobs across the metro where TPO is the right system for the building.
Sure-Seal is Carlisle's EPDM product line, one of the longest-running EPDM brands in the industry. It's available in black and, in some product configurations, white surface options, and Carlisle produces it in multiple thicknesses and sheet widths to reduce field seams on larger roofs. Carlisle also offers tape-based seam systems for Sure-Seal that have largely replaced older liquid-adhesive seaming on new installations, which is a meaningful upgrade for long-term seam reliability.
Carlisle's FleeceBACK product line bonds a fleece backing to the underside of TPO or EPDM membrane, which changes how the membrane gets attached to the roof. Instead of direct mechanical attachment or standard adhesive bonding to insulation, FleeceBACK membranes are typically set in a specialized adhesive or hot asphalt over a cover board, which improves puncture resistance and can simplify recover projects over certain existing roof types.
Carlisle also manufactures polyiso insulation and cover board products under its Insulfoam and related brands, along with fastening systems, adhesives, and flashing accessories designed to work as a coordinated system with their membrane lines. Using components from a single manufacturer's coordinated system, rather than mixing components across brands, is generally the more straightforward path to a full manufacturer warranty on a project.
Membrane selection on any given project comes down to the building's use, the deck type, budget, and warranty needs, not brand loyalty to a single manufacturer. Carlisle's product range gives us options across TPO, EPDM, and PVC on a single manufacturer's warranty program when that's the best fit for a project, which simplifies the warranty conversation for the owner compared to mixing components from different manufacturers.
We compare Carlisle's product specifications against other major manufacturers on every project where membrane choice isn't already dictated by an existing roof system or owner preference.
Carlisle distributes through a network of regional roofing supply houses rather than selling directly to property owners, which is standard practice across the major single-ply manufacturers. Lead times on standard TPO and EPDM product are generally short since those are high-volume items most distributors stock regularly; specialty items like FleeceBACK membrane or less common thicknesses can carry longer lead times depending on current demand and distributor inventory.
We factor lead time into project scheduling on any job with a tight completion window, particularly reroofing work we want to finish ahead of our spring and summer thunderstorm season rather than mid-project when a partially exposed deck is most vulnerable to weather delays. On larger commercial projects, we coordinate material orders well ahead of the planned start date specifically to avoid a schedule gap caused by a manufacturer backorder.
Installer requirements for a full system warranty typically involve some level of training or certification on the manufacturer's specific installation methods, which varies by product line and warranty tier. We review what a given project's target warranty actually requires before quoting the job, since the labor and inspection requirements behind a stronger warranty affect both cost and schedule.
Carlisle SynTec Systems is a division of Carlisle Companies Incorporated, a diversified manufacturer with multiple building products divisions.
Carlisle offers system warranties that can cover membrane, insulation, and accessories when the full assembly uses Carlisle-approved components installed to their specifications. Exact warranty terms and coverage vary by product and project.
The fleece backing adds a layer of cushioning and puncture resistance compared to standard membrane, which can help in hail-prone regions, though field membrane thickness still matters for overall impact performance.
They're different membrane chemistries and aren't welded or bonded directly together, though they can be used in adjacent roof sections with proper transition flashing details.
Carlisle SynTec operates manufacturing facilities in multiple states as part of its broader building products operations; we don't have specifics on which plant supplies material for any given project.
