Sika Sarnafil: The PVC Specialist We Call On for Chemical Exposure
Where Carlisle and GAF give us TPO, EPDM, and PVC under one roof, Sarnafil is a manufacturer whose reputation is built specifically around PVC membrane, and it shows in the depth of their product range for that one chemistry. When a Midland building has real grease, oil, or chemical exposure on the rooftop, Sarnafil is often the line we reach for first.
Why Sarnafil's PVC Track Record Matters
Sarnafil has manufactured PVC roofing membrane for decades, and that history matters because PVC's performance depends heavily on plasticizer formulation and retention over time — older, poorly formulated PVC sheets were known for plasticizer migration that left membranes brittle well before their expected service life ended. Sarnafil's long production run gives us a track record to point to rather than a newer product with less field history behind it, which is a real consideration on a membrane chemistry where formulation quality is the whole ballgame.
Their sheets come in standard gauge ranges with reinforced and fleece-backed options, covering both new construction and recover applications over existing substrates.
Where Chemical Resistance Actually Gets Used
PVC's resistance to petroleum-based oils and greases is the main reason to specify it over TPO, and that comes up regularly in Midland given the mix of restaurant and hospitality kitchen roofs, auto dealership service-bay buildings, and industrial facilities with process exhaust near the rooftop. Standard TPO can degrade under sustained grease or chemical exposure in these settings; Sarnafil's PVC formulation holds up considerably better, which is worth the added material cost on any roof with that specific exposure profile.
We don't default to PVC across every spec — on a clean warehouse roof without chemical exposure, TPO usually performs just as well for less money. Sarnafil earns its place specifically where the exposure profile calls for it.
Welded Seam Performance
Like all PVC, Sarnafil sheets hot-air weld rather than using adhesive seams, and a properly fused Sarnafil seam is durable and testable with a probe the same way any quality welded seam should be. PVC's plasticizer content changes weld temperature and speed requirements relative to TPO, and crews running Sarnafil need PVC-specific technique rather than assuming TPO settings transfer over. We flash every penetration separately and probe every seam before signing off on a Sarnafil install, the same discipline we apply across every membrane system we run.
Where we've specified Sarnafil PVC in Midland
- Restaurant and quick-service roofs near kitchen exhaust and grease-trap venting
- Auto dealership service-bay roofs with automotive fluid and exhaust exposure
- Industrial buildings with process exhaust or chemical handling near the roof deck
- Hospitality kitchen and back-of-house roof sections
- Recover projects extending an existing PVC roof already performing well
Wind Uplift and Attachment
Sarnafil PVC runs mechanically fastened or fully adhered, following the same uplift-design logic as any single-ply system on Midland's open, Exposure C terrain. Perimeter and corner fastening gets tightened beyond the field pattern to handle the higher negative-pressure zones a flat, unobstructed site sees during the straight-line wind events that come through with dryline storms, and fully adhered systems spread that uplift resistance more evenly on taller or more exposed buildings.
Cover Board and Hail Considerations
Impact resistance on a Sarnafil roof depends on cover board selection as much as membrane gauge, the same principle that applies across every single-ply system. A dense polyiso or wood-fiber board spreads hailstone energy before it reaches the deck, and that pairing matters more to hail survivability in a bad Midland spring than which PVC manufacturer's sheet sits on top. We size board density to the building's hail exposure history, particularly on industrial and auto-service buildings where the roof's chemical-resistance requirement doesn't automatically mean it's also specified for maximum impact resistance — those are two separate decisions in the spec.
Warranty Structure
Sarnafil offers material-only and system-level warranties, with system coverage extending to labor for warranted repairs when installed by an approved contractor following their published details. Because PVC's long-term performance depends so heavily on plasticizer retention, Sarnafil's warranty terms and published service-life data are worth reviewing directly with owners rather than assuming all PVC products carry identical long-term performance.
We document board pairing, fastening pattern, and seam probe results on every Sarnafil install, since that record is what a warranty claim gets evaluated against down the road.
Questions About Sika Sarnafil Systems
Is Sarnafil only relevant for restaurants?
No — it comes up on any building with grease, oil, or chemical exposure at the roof level, which includes auto service facilities and certain industrial buildings, not only restaurant kitchens.
Is Sarnafil PVC more expensive than standard TPO?
Generally yes, due to the plasticizer chemistry, but the added cost is justified specifically where chemical resistance is actually needed, not as a blanket upgrade.
Does Sarnafil PVC handle Midland's UV exposure well?
Yes, the light-colored reflective surface performs comparably to white TPO under direct sun, keeping surface temperatures down relative to darker membranes.
How does plasticizer retention affect a Sarnafil roof's lifespan?
Modern formulations retain plasticizers far better than older PVC products, which is part of why Sarnafil's long manufacturing history and track record matter when comparing PVC options.
Can Sarnafil PVC be installed over an existing roof?
Often yes, provided the existing substrate is dry and structurally sound, which we confirm with moisture testing before recommending recover over full tear-off, including a check of cover board condition beneath the existing membrane.
