For a low-slope or flat roof in West Palm Beach, the choice usually comes down to two single-ply membranes: TPO and PVC. Both perform well in the Florida sun; the right one depends on your building and budget.
| Factor | TPO | PVC |
|---|---|---|
| Installed cost per sq ft | $4.00–$8.00 | $6.00–$10.00 |
| Typical lifespan | 20–30 years | 25–30+ years |
| Chemical / grease resistance | Good | Excellent |
| Ponding-water tolerance | Good | Excellent |
| Seams | Heat-welded | Heat-welded (superior long-term) |
TPO is the value leader: a reflective white membrane that keeps cooling costs down and performs well on most residential and light-commercial low-slope roofs. For a straightforward flat section with good drainage, TPO delivers strong performance at a lower price.
PVC's chemical resistance and long-term seam durability make it the better choice where grease or chemical exposure is a factor (restaurant exhaust, some commercial uses) or where ponding water is hard to avoid. Its welded seams stay watertight for decades.
West Palm Beach sits in Palm Beach County, which is not a legal High-Velocity Hurricane Zone, but the county wind code still governs membrane attachment and edge-metal detailing. We build to that code — and to full HVHZ spec on request — with product-approved assemblies on every flat roof.
