Sarnafil built its name specifically on PVC membrane manufacturing, long before PVC was a common single-ply option in the American commercial roofing market, and that focus still shows in the depth of their PVC product range under current Sika ownership.
Where some manufacturers treat PVC as one line among several single-ply chemistries, Sarnafil's roofing business developed around PVC membrane specifically, which translates into a wider range of PVC gauges, reinforcement options, and colors than we typically see from a manufacturer where PVC is a smaller part of a broader TPO-and-EPDM-centered catalog. That depth matters on a job with specific exposure or fire-rating requirements where a narrower product range might not have the right configuration.
That product depth also shows up in reinforcement scrim options, which affects how the membrane resists tearing at a stress point versus how it handles thermal movement across a large field. We match scrim type to the building's specific stress profile rather than treat every PVC job as needing the same reinforced sheet.
Sarnafil's PVC formulation has decades of documented field performance behind it, which we point to specifically when an owner is comparing a Sarnafil bid against a newer PVC entrant with a thinner track record. Longevity claims matter less to us than actual seam and membrane performance data, and Sarnafil's history gives more of that data to reference on a comparison.
Sarnafil PVC welds with the same hot-air process described on our PVC roof systems page, and we hold the same seam-testing discipline on Sarnafil installs as on any other membrane brand - probing every seam before calling a section complete rather than trusting the welder's calibration alone. NEPA's narrow cold-weather install window applies here too, and we plan Sarnafil install schedules around it the same way we would for any PVC or TPO job.
Sarnafil offers both mechanically fastened and fully adhered PVC systems, and the choice between them follows the same wind-exposure and deck-condition logic we apply across manufacturers. A cold-storage building with a sound steel deck and moderate exposure often works fine mechanically fastened; a taller or more exposed structure, or one that will carry rooftop solar later, more often calls for a fully adhered system.
We spec the attachment method based on the specific building's site conditions rather than default to whichever installs faster, since the wrong attachment choice on an exposed roof shows up as a wind-uplift problem years down the line, not on day one.
Cold-storage buildings feeding the I-81 distribution network and food-processing facilities in the Hazleton and Pittston industrial parks are where we reach for Sarnafil most often, for the same chemical-resistance reasons detailed on our PVC systems page. Sarnafil's specific product depth in that category gives us more configuration options when a facility has an unusual exposure profile - a mix of grease, refrigerant off-gassing, or specific fire-code requirements tied to the occupancy type.
We coordinate directly with a facility's operations team on these jobs to understand the actual exposure history before finalizing a Sarnafil spec, rather than rely solely on the building's stated occupancy classification to drive the membrane configuration.
Sarnafil's PVC range includes both standard white membrane and additional color options, which comes up on jobs with an architectural requirement for a specific roof appearance visible from an adjacent taller building or public roadway - a consideration on some of the properties near downtown Wilkes-Barre and Scranton where roofs are visible from surrounding hillside neighborhoods.
The white membrane option carries the same reflectivity benefit discussed for other manufacturers' white single-ply systems, relevant on cold-storage and food-processing buildings running rooftop mechanical equipment hard through the summer months. We check the manufacturer's current reflectivity documentation against the specific product configuration before citing a number on a bid.
Sarnafil's roofing business is centered on PVC single-ply systems. For TPO or EPDM, we typically look to other manufacturers in our lineup.
Pricing is generally competitive within the broader PVC market. We quote it alongside other manufacturers' PVC lines so the specific numbers are visible before a decision.
In some cases, if the existing roof passes a moisture scan and deck inspection. We evaluate recover eligibility on site rather than assume it from the roof's age.
It can work, but on a standard warehouse without grease or chemical exposure, TPO is often the more cost-effective choice - see our 80-mil TPO page.
Warranty length depends on the specific system and our current certification standing with the manufacturer at time of bid, which we confirm and provide in writing on every quote.
