TPO vs. EPDM Commercial Roofing in Texas
The two most common single-ply roofs, compared for North Texas.
For a Texas commercial roof, TPO and EPDM are the two most common single-ply systems. TPO's reflective white membrane bounces heat and can cut summer cooling costs — a real advantage in DFW's climate — and runs about $5.50–$8.50 per square foot installed. EPDM (a black rubber membrane) is time-proven, durable and flexible, and slightly cheaper at about $4–$6.50 per square foot. The best choice depends on your building's cooling load, budget and roof details.

| Factor | TPO / EPDM |
|---|---|
| Membrane color | TPO reflective white · EPDM black |
| Installed cost | TPO ~$5.50–$8.50/sq ft · EPDM ~$4–$6.50/sq ft |
| Energy / heat | TPO reflects heat (lower cooling) · EPDM absorbs heat |
| Lifespan | Both ~20–30 years |
| Seams | TPO heat-welded · EPDM taped/adhesive |
| Best for | TPO: sun-exposed, cooling-sensitive · EPDM: proven durability, budget |
Why TPO is popular in Texas
In DFW's long, hot cooling season, TPO's reflective white surface keeps the roof — and the space below — cooler, which can meaningfully lower cooling bills on a large building. Its heat-welded seams are also strong and consistent. That combination is why TPO is the most-requested single-ply system in North Texas.
Where EPDM still wins
EPDM has a decades-long track record, excellent flexibility in temperature swings, and a lower up-front cost. For some buildings and budgets it's the smart pick. We help you weigh both against your roof's size, exposure and details — see typical commercial roof cost, system lifespans, and how warranties compare.
