Based on the provided content, there is a distinction between the standard lifespans of TPO (Thermoplastic Polyolefin) and EPDM (Ethylene Propylene Diene Terpolymer). There is no mention of “torch-on” roofing lifespans in the text provided.
Regarding the comparison between TPO and EPDM:
- TPO Lifespan: The National Roofing Contractors Association benchmarks TPO at 20–30 years. However, under different sections of the guide, the typical lifespan is also noted as 15–20 years with proper maintenance.
- EPDM Lifespan: This membrane typically reaches 25–30 years, though some sections of the text suggest a range of 20–25 years depending on maintenance and installation.
Both systems require professional workmanship and annual inspections to maximize their durability. Factors such as UV exposure, thermal expansion, and the quality of the seams (heat-welded for TPO versus adhesive-bonded for EPDM) significantly influence how long these flat roof systems will serve a property.
