Not at all, any competent boat shop can fix a fiberglass roof.
Assuming it is standard thickness fiberglass and not just a thin 'glass material like Filon affixed with contact cement.
Fiberglass boat decks/roofs are almost always multiple layers of cloth (many styles and thicknesses). The substrate/"core" is wetted and the first layer applied. More slow hardening resin is applied so that the cloth is thoroughly wetted out and all air bubles can be worked out. Before the resin starts to harden, a second layer is applied, wetted and a third. The reason this layers are done at the same time is because epoxy resin leaves a film (called "blush") after curing which must be sanded off before additional layer of resin and cloth are applied.
No offense...but been in a coastal environment all my life and have worked with fiberglass since I was an infant. It's actually wax...literally wax that comes to the surface. Never heard it called blush.
