The roof looked perfect when installed in 2019, but over time it has developed the pattern shown. The original delivery of roofing material was as ordered, but apparently short of what was needed. Additional panels were delivered a couple of weeks later. My contractor was in charge of everything. Is this color variation within customary standards? Standing seam galvalume was used.
Being this new, if this is a clear coated Galvalume product, I wonder if the variation doesn't have to do with how the clear coat is weathering. My suspicion is that over a period of many years, the differences will reduce dramatically. I would suggest going back to the manufacturer for clarification and discussion.
