Comparison
TPO vs. EPDM
Side-by-side comparison of the two most common single-ply commercial membranes — performance, cost, longevity, and which conditions favor each.

How this comparison was built
Criteria were fixed before evaluation and applied identically to both systems, per the CRI Methodology. Sources include ASTM standards, manufacturer technical data sheets, and field-performance research — not marketing.
Side by side
| Criterion | TPO | EPDM |
|---|---|---|
| Typical service life | 15–25 years | 20–30 years |
| Seam method | Hot-air welded | Adhesive/tape |
| Solar reflectivity | High (white) | Low (black; white available) |
| Track record | ~30 years, evolving formulations | 50+ years, stable chemistry |
| Typical installed cost | Placeholder range | Placeholder range |
| Best-fit climate | Cooling-dominated | Heating-dominated |
Condition-based guidance
Placeholder: which building profiles favor each system (climate zone, rooftop equipment traffic, chemical exposure, budget horizon), plus the cases where neither is the right answer.
