Classified Roofing Systems

Please be advised that any changes to components of a classified roofing system, as described in an ICC-ES evaluation report, negates ICC-ES recognition of the classification. The changes may or may not affect the actual classification, but until they are subjected to appropriate testing or are evaluated by a testing agency and declared to be acceptable under the designated classification, ICC-ES is unable to make a determination as to proper classification.

ICC-ES does not offer an opinion on changes to a recognized product or system until evidence has been submitted, evaluated, and recognized in the evaluation report. Fire-resistive assemblies are recognized by ICC-ES only as described in the applicable evaluation report. Assemblies made up of different components than those described in the evaluation report are not recognized.
