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.

We manufacture tremendous value into every one of our AP Panel metal roofs, which offer the look of standing-seam roofs at a lower cost. You get big benefits like extra durability, a gorgeous appearance and potential savings on energy bills and homeowner’s insurance. AP Panels are a smart idea for new construction and applications where the existing roof covering is removed to decking. They're designed with residential metal roofing in mind, but work very well on commercial buildings, too.
