A Class 4 rating is the highest tested rating for impact resistance under the UL 2218 standard for metal roofing panels. This certification indicates the roof material has passed testing that simulates withstanding 2” diameter hail with no visible defect. Our 26 gauge panels (and thicker) pass this testing.
