I am currently in my camper at the end of this Thanksgiving weekend of camping and just removed the vent shroud in the bathroom to confirm and the backside of my EPDM roof is indeed black

What year is your Montana?
Is it possible they made a change from EPDM to TPO?

And, if it is TPO, isn't there a different caulking you should use?

Thanks,
Brad

Mine's a 2011. They probably did make a change to TPO but I don't know when. I would think the dicor caulk would work with both but I'm not certain

I would agree with the others - confirm the membrane type, glue the pieces back down once the chip board decking is dry, then Eternabond the area and lay down the Dicor caulking to chamfer the edges of the tape to the roof. Clean everything with acetone or the Dicor-recommended cleaner.
If you have the time and energy, I highly recommend taping the front and back caps where they join the flexible roof membrane. We eliminated a small leak that let water run down the metal transition piece, resulting in much peace of mind.

Eturnabond makes a roof cleaner that works really well for their product. If you need to buy a cleaner for your roof, check out their cleaner when you order your tape. Cut your tape to size first before peeling off the backing. Get it lined up how you want it and start at one end peeling off the backing as you go. This stuff is EXTREMELY sticky and once its down, there is no pulling it back to realign. Try getting all air bubbles out as you lay it down, especially along the edges. I found using my fingers as well as a stiff plastic putty knife does the job. Check out some U-tube videos for more info. This is a great product and will definitely fix your issue. When you re glue your roof make sure there are no bubbles beyond where you opened up the roof. If there are some, make sure you glue those down as well. As far as putting down dicore along the tape edges, if you work the tape edges down well, its not necessary, but won’t hurt either. Good luck !
