merits and how of fiberglass roofing

I have to build a canopy roof for a car park in the front yard, and I am considering using fiberglass for roofing.

How is fiberglass fabricated and installed for this purpose?

Could it be feasible to get some neighbors together to make the fiberglass sheets ourselves and install them ourselves – like making hollow cement blocks and raising a wall with them?

Or should I better get a commercial outfit?

Any practical advice is most welcome.
