Soft Roof

I just purchased an 02 26 ft Land Yacht Motorhome. When installing a satellite dish I noticed the roof above the driver to be " soft ". At first I thought it was rotted but after finishing mounting the reinforcement plate I realized the fiberglass roof had separated from the wood it was glued too. The wood underneath seems solid. I'm wondering if I should drill some small holes ( oh No ) in the roof and inject some glue to solidify that section again. It extends about one foot from the edge and rearward three feet. ANYBODY BEEN THERE DONE THAT??

Thanks,
