I have not seen this happen before. Can you post a photo of what is happening? Do the panels show oil canning before they are installed?

We are a residential home builder for over 25 years. We have a new roofer who is installing a standing seam metal roof to a garage. The roof has a terrible amount of oil canning. More than we have even seem. The roofer thinks the cause could be the zip tap seam. Have you ever experienced this problem with zip tape?
Thanks

Unless the tape is definitely proud of the sheathing, I haven't see it that much. What is the mil thickness on the tape and how true is the rest of the decking?
