Roof tape?

If Eternabond is properly applied chances are it's not leaking. I would use something like a small flat screwdriver and gently lift the area where you suspect it's loose and see if it actually is. Mine is 4 years older than yours, the tape is obviously not new, but the seal is still intact and there are no problems.

If you can't remove the old tape, cut off any loose tape, clean, and recover with wider eternabond tape. I had to do that to the slide top on my Holiday Rambler.

Remove the old and go back with Eternabond.

Hey David, I just completed a project on my 87 Gulfstream. I bought a
5gal bucket of henry's white elastic roof coating. I had had a problem
area on the right front from where the batwing was. I removed the tape
there and used a tape they sold with it that looks like gause.

You put a coat of the sealant down and then place the tape into it.
after it dries then re-coat. The rest of the roof because of time
constraints I just sealed then taped and re-sealed. put about three
coats on altogether and I am in the northwest we have had about 10 inches of rain in the last 5 days and no leaks at all.

Bought the stuff at Home Depot. cost was about 100.00 for sealer,tape,and brush to apply. Hope that helps.
