We(and that's being generous since it was mostly me) used an exterior grade silicone caulk. I think I had to talk the lazy cheap @ss into splurging for it.
The fasteners we used had a little vinyl washer that was supposed to do the job, but failed miserably. I'm surprised Arrow has never had a class action lawsuit over that, and been force to send out proper roofing screws.
I think you could probably tuck and glue a drip edge under like you mention and have it fix your problem.
You might also be having condensation form on the underside of the fiberglass and drip down which a wall vent or two might relieve.
