Bit of guesswork here Prendi. Perhaps these are read-made fibreglass panels, and the "gel coat" has come away from the glass mat. Gel coat is the first coat placed in the mould ...... the one that becomes the face side.
More likely ....... you simply have the fibreglass alternative to the old pitch & felt covering.
Such a covering is simply applied over a plywood deck, as you would with felt. If so, it does sound as though the last coat of polyester resin has blistered and lifted. If it has separated from the mat, then it's un-reinforced, so it will eventually crack and leak.
It most likely needs attention....... or replacing.
