My metal roof was installed a week ago. The installer did not put on the ridge cap yet and has left one whole sheet off the roof. The sheet was supposed to go next to a dormer in the center of the roof. Do I need to worry about moisture/rain getting under the sheets? or anything else?

If the roof has been properly and fully "dried in" with good underlayment, you should be okay. Of course, this does need to be wrapped up fairly soon.

What does properly and fully "dried in" mean? What would be a good underlayment? This is also the roof that had the holes punched in the OSB deck to anchor the safety harnesses. When I see one thing not done properly, I'm concerned. When I see more than one, I'm seeing a pattern.

Generally, the suggested underlayment beneath most metal roof systems is one of the following: 30-pound felt; premium synthetic; ice and watershield; fire-rated underlayment. Proper underlayment installation will keep water out.

Thanks. How about the "dried in" part? What does that mean? Does this happen before the metal installation? Is that say no rain for X days before installation to make sure everything is dry?

Sorry, "dried-in" simply means underlayment has been installed to make the roof watertight prior to the metal being installed. In some cases, if the old shingles are left in place, additional underlayment is not installed and the old shingles serve as the "dry-in".
