TPO vs EPDM vs PVC, Lab Results Expose Which Roofs Actually Last
Lab testing and real world data show PVC roofing lasts the longest (30+ years), has the best fire resistance, and the lowest lifecycle cost. Premium TPO performs well for mid term ownership, while EPDM and low grade TPO fail earlier due to seam, adhesive, and ponding water issues. Roof coatings can extend aging systems 10 to 15 years when applied before failure.
