Is the fiberglass flush up against the roof deck? If not, you could place insulation trays aka soffit baffles between the fiberglass and the roof deck. Then you would need to add eave vents and a ridge vent. The insulation trays would connect the vents for air flow.
I did this on our house to allow air movement from the eave vents up to the ridge vent. Because your roof material is not a perfect solar reflector, some heat will radiate down through the roof deck. The soffit baffle allows air flow to vent the heat up through the ridge vent. That convection moves heat up and out of the roof and reduces the heat radiating downward into the shed.

With all that said... I wonder how much reflected solar heat you are getting from the asphalt. Using some sort of shade cloth (maybe even a foil/mylar faced tarp) to shade the south side (or open door side) of your shed could be a quicker and easier way to cool things off.
Good luck,
