Skin repairs on a Schroeder type trailer

I've got a trailer that was damaged a few years back when a load of
snow slid off the roof and landed right on the skin. About 5 of the
fiberglass ribs are broken and the skin is fractured, split and
generally ripped apart in a few areas.

Has anyone got some idea about how to repair the broken skin? I can
easily make new ribs, but the skin looks a bit challenging to repair.
Maybe replacing the broken sections with pre-cured laminated sheets is
the way to go?

Any thoughts would be appreciated................heck, I guess if I
can build a glider I can repair a busted trailer top!

Thanks,
Brad
