Your roofs outer skin is a1/4 inch of gel coated fiberglass laid over or I should say impregnated into a layer of 1/4 inch marine plywood .
It is what is referred to as a floating skin roof meaning that outter skin is floating ( not laminated or glued to the foam and substructure below it.
You may find sections of the roof that appear to be loose or have bubbles or pockets under it this is normal as the roof is ment to be able to move somewhat
Except of course where it is fastend in place along the drip rails and vent ETC.in these places it is important to periodically check for loose or broken/ rusted off screws particularly at the side drip rails.
In most cases the vents and skylights are surrounded by wood structure 2x material which was used as part of the substructure and gives the vent or skylight something substantial to be screw into. But most other add ons like satellite dishes,solar panels ETC. are simply just screwed into the roof skin which is usually 3/8 to a 1/2 inch in total thickness and adequate for the job.
When removing anything from the roof it is important to seal the screw holes or any openings left behind using a good quality roof sealant like Dicore.
Hope this helps
