Indentations in roof

Hello everyone, I bought a 24 gauge dark bronze standing seam flat panel roof from AB Martin. It looks beautiful up until it was put on. Not knowing the right or wrong way I simply took what my contractor said as gospel. He never took the existing asphalt shingles off. He put furring strips on and then the metal panels. The problem as you'll see in the pic are the unsightly indentations. They seem to appear near the furring strips. He def didn't walk on the roof. Any idea what could be causing this?

Because of the consistent location of the ripples, I suspect there is a low spot in the roof there. The battens perhaps could have been evened out there to compensate.. Are they willing to try to remove the roof and re-do it? This is probably a defect in the original decking or even the framing which would have been present even if the old shingles had been removed. I see, also, that the battens have forced the roof up into the clerestory window ... is there a plan for that to make sure that water is not forced toward the window and also that, someday, the window can be replaced?

+1 I wouldn't be surprised if there was a consistent framing defect in that location. Is there load bearing beam that runs through that location?		Eric Novotny An informed customer is the Best Customer! 1/13/2017	Share Or copy this URL: https://www.metalroofing.com/spirit/comment/21754/find/
That spot is over the garage. There isn't a beam from what I can see. I figured that if we were to take the shingles off it would help with a flat surface. Yesterday I climbed up and I am 90 percent sure that the furring strips are causing this. Only happening midpoint in the span. So how could my contractor fix this now? And taking the shingles and furring strips off wouldn't make any diff?		John Smith 1/14/2017	Share Or copy this URL: https://www.metalroofing.com/spirit/comment/21755/find/
I would start by removing the metal panels and then running a strong at various places up the roof over the battens, until the problem is found. Once the problem is identified, a method of correction should be apparent.
