ACCEPTED MATERIALS and SYSTEMS for a RoofStar 5-year Guarantee, RoofStar 10-year Guarantee, or RoofStar 15-year Guarantee. The page links below provide details of materials or systems manufactured by RCABC Associate Members or Affiliate Members*. While these materials and systems are accepted by the RGC for use on projects intended to qualify for a RoofStar Guarantee, the acceptance of these materials should not be construed as an indication of the quality or performance of other materials or systems not listed in this Manual. It is the sole responsibility of the Design Authority to assess the performance capability and material suitability for specific design requirements. Where the RPM lists manufacturer's accessories, these are also displayed below but are not considered "accepted" by the RGC (RCABC Guarantee Corp.). Some material pages are missing acceptance dates; this is a carry-over from a prior iteration of the RPM, in which those dates were not recorded. If the date is missing, it is usually shown with the acronym "TBD" (To Be Determined) or "TBA" (To Be Added).
