I had a contractor install this roof just recently. I'm concerned about leaks specifically where the roof bumps out from the main roof. I was under the impression that the screws should connect with the high ribs but zero screws hit the high rib in my last picture. I do have a second bump out where the contractor hit the high rib but still ran a screw in the middle of the flat part of the panel. Should I have the contractor redo some of this work or am I overthinking it?
