TPO vs. Other Flat Roofing Materials
| System | How it differs | When to discuss it |
|---|---|---|
| TPO | This thermoplastic membrane uses hot air welded seams. | Lightweight and low slope systems with different spec options fits the building. |
| PVC | Another thermoplastic single ply roofing system that uses welded seams. However, different from TPO. | PVC is best when your roof will face grease or chemical exposure, or the project calls for it. |
| Modified bitumen | A roofing sheet system made with polymer modified bitumen that is often installed using a different method depending on the product. | High roof raffic, roof compatibility, and age all guide this decision. |
| EPDM | This single-ply membrane uses seams with tape or adhesives rather than the hot air welding. | When the design preference, color options, or climate allows for it, EPDM worth comparing. |
The best material depends on your roof, property use, current drainage, weather exposure, and budget. Check out our page on modified bitumen roofing, built-up roofing, or commercial roofing for different roof options.
