Fiberglass roofing system

Anyone recommends fiberglass roofing system (as done on boat or wood board) for replacing the old bitumen flat roof?

Absolutely not! Different coefficient of contraction and expansion and would be an absolute mess when the adhesive hit the asphalt.

The bitumen will be removed. What asphalt layer and how you would install it? From what I was told, here will be no asphalt on top of this fiberglass coating, which is on the compressed wood boards, on top of the insulation board. How good is this roof system?

Bitumen is the asphalt.
