What sort of "rating" are you seeking?
UL 2218 was developed in 1996 and I believe that the Alcoa product was approved for it then. That particular product is now manufactured by Classic Metal Roofing Systems and I think they can help you with this. During work hours they have a staffed live chat on their website at www.classicroof.com. That might be the quickest way to reach them, or else call 1-800-543-8938.
I am purchasing a home with an Alcoa Lifetime Roof installed in 1996. Is there a way to get the rating as installer unknown?
UL 2218 Impact Rating of 1-4 scale.
Thanks!
Henry
