New build installation help

Hello, my husband and I are building in middle Georgia. We're 2/3 of the way through the roof install, and we've come across several issues that our installer (who is never on site) says are not issues. Just not sure if we should be concerned or not. We would greatly appreciate any guidance. We've looked through he installation instructions on the manufacturer's website, and our installer is not follow ping the instructions. Firstly, how much damage to the roof should we expect during the install? We have debts and scratches all over the roof. Is that normal? We were not expecting there to be damage at all. Second, none of the flashing is installed under the house wrap. They also installed aluminum flashing on our decks, which I thought would corrode up against pressure treated lumber. Third, the manufacturer says there should be a four inch minimum from the valley to the beginning of the first panel. We have 2" maybe. Big deal or no? Fourth, they've used sticky tape everywhere, and the metal is already pulling up. There are places along the edge of the roof line where there's a 2" gap between the decking and the aluminum because the sticky tape has come unstuck from the roof felt. I think these are he main issues. We've done plenty of renovating, but this is our first metal roofing adventure, and an expensive adventure at that. Not sure if we're having unrealistic expectations or if we are in fact dealing with problems. Any advice would be greatly appreciated. Thanks for your time!

Thanks much. Some of your questions are subjective. I would not expect to see a lot of dents and scratches from the ground though. The aluminum against pressure treated wood will likely corrode. It's not uncommon for flashing to be outside of the house wrap. Though, yes, ideally it would be behind it. As far as the valley ... I always suggest installing per manufacturer specifications. I would suggest calling the manufacturer now to get them involved in helping evaluate things.

Thanks so much for your reply. One more question - is not hemming the edges going to cause any issues in the long run. The manufacturer recommends hemming but it isn't required so our installer doesn't do it.
