This is a question about the industry = Do you know what % of the current manufacturers have tested their products to the Underwriting Laboratories 2218 hail resistant standard? Do you know what % of metal roofing is done by independant roll formers?

Hi wdp,
Thanks for the question.
I am confident that a high percentage of the larger metal panel manufacturers have products listed per UL 2218. For local/portable roll-formers, my belief is that the percentage is lower.
I do not have datas on the percentage of roll-forming done by independent roll-formers.
