TPO Roofing Systems
TPO stands for Thermoplastic Polyolefin and is a single ply roofing membrane generally white in color. Due to the fact that it is white, it reflects heat away from the building. This can reduce cooling costs in summer. TPO is a blend of polypropylene and ethylene-propylene rubber. TPO is used in commercial and flat roofing.
- How long does a TPO Roof Last? TPO Roofs can last up to 25 years if properly maintained
- How much does TPO cost? TPO costs about $8 – $12 per square foot (installed)
EPDM Roofing Systems
EPDM stands for ethylene propylene diene monomer rubber and is also a single ply roofing membrane. EPDM roof membranes are generally black (though white is available) and tend to absorb heat. It comes in a few different thicknesses including 45 mil and 60 mil. It can be installed fully adhered, mechanically attached or ballasted with seams sealed using tape or liquid adhesives. It can resist UV Rays, aging, and weather such as hail.
- How long does an EPDM Roof last? EPDM Roofs, if well maintained, can last 25-30 years
- How much does an EPDM Roof cost? EPDM roofs cost about $7.50 – $9.00 per square foot (installed)
Comparison | TPO Roof | EPDM Roof |
| cost | TPO costs about $8 – $12 per square foot (installed) | EPDM roofs cost about $7.50 – $9.00 per square foot (installed) |
| Weather/heat Resistance | Resistant to UV, and temperature fluctuations. Hail can damage it over time. More puncture resistant than EPDM | Resistant to UV, Hail, and temperature fluctuations. Not as puncture resistant as TPO |
| Lifespan | Between 15-30 years if well maintained | Between 25 -30 years if well maintained. |
| ROI (Return on Investment) | TPO lasts decades when properly maintained and also delivers a good return on investment | Due to their long life span and durability, EPDM provides a good return on investment |
