Numerous warranty options, from 5 to 30 years, are available to accommodate almost any budget and building owner requirement. Puncture, high wind and hail coverage are also options, making EPDM an even more appealing roofing membrane. The 30- year warranty options that are now available are based on historical performance, not research projections.

In the past, long-term EPDM membrane warranties required manufacturers to address the issue of EPDM roof systems that were exceeding their warranty period. EPDM roof systems that exceed their warranty period can now have the warranty period extended. The warranty extension programs involve inspection of the roof and the completion of recommended repairs, maintenance and/or system enhancements.
