did i mess up on roof repairs?

the sides consists of the inner wall board, styrofoam insulation and plywood = these are bonded together.,with fiberglass panel laid over the top but none of this is laminated. I am talking about the front of the trailer .... this consists of a fiberglass panel that has a paper backing..... under this is insulation that is paper backed insulation as would be in one's home. then there is the inner wall material., none of this is bonded together. no way for it to be bonded. There are a few 1*2 studs that i can find no points of fasteners or glue to the fiberglass. The inner wall material is connected to these studs.
