Awning question 2002 coleman with replacement roof

I'll double check tonight but I'm pretty sure the awning rail on my 2005 Fleetwood is screwed into the roof. I have the aluminum roof also. There's adhesive on the back to create a watertight seal around the screws and to help prevent water from flowing under the rail and thus under the canopy. At the very least, there should be two screws holding the awing bag into the rail.
