I have installed a Menards brand standing seam metal roof on a gambrel roof. The sheathing is 5/8 CDX plywood, covered with 30# felt paper.
I was able to install all the roofing panels. I was also able to set 2 screws at the very top of each panel to secure them. The screws will be covered by the ridge cap.

The ridge is 48' long. I left the felt paper lapped and covering over the ridge vent slot that I cut into the CDX plywood (with the plan to cut it out from underneath after the ridge cap was installed). No sooner did I begin to install the ridge cap, rain set in and I scampered off the roof. Since that time, the weather has continued downhill and I am unable to get back up on the roof. We are now dealing with ice and snow.

I know that some of the precipitation that hits the ridge is getting underneath the roof panels. I assume that a good portion of it is also running over the top (likely due to snugging down the panels with the 2 screws mentioned at the beginning of this post).
Anyway, I am (anxiously) awaiting for El Nino to provide a short string of warmer days so I can get back up there and finish. In the meantime, what kind of problems have I created for myself in the short and long term?

Thanks for the quick response, Todd.
The felt paper was in excellent condition as I covered it all with the 16" wide roofing panels. The entire roof is covered, excepting the rake trim pcs at the top gambrel roof and the ridge cap. I'm that darned close to being done.
I was concerned for the water that would get trapped beneath the panels. I'm not an expert by any stretch, but I did notice that felt paper actually absorbs some of the moisture from rain, then dries out fairly quickly from sun and wind. I kinda hoped that the felt would do the same absorption under the metal roofing panels, but remain concerned that it can release it. I presume that the G100 + paint on the bottom sides of the roof panels will keep me protected thru this (hopefully) short term debacle.
