This is a great thread!! I'm currently educating myself on the best way to protect/repair my roof on my 28' 2000 Tioga.
I don't see a clear reference to this so I wanted to ask; does it seem like the best practice is to remove the black membrane altogether and then apply a new coating? Mine is bare and black/chalky in several large spots allover my roof. It looks as though the previous owner didn't do a good enough job on the white coating the last time he covered it.
There is very thin (3/16-1/8") plywood directly under the black membrane. I just planned on ripping the whole membrane off and going the Grizzly coating route (just got off their chat line) right over the plywood. Probably curing the first coat, eterna-bonding the seals, flashing, and seams before applying the second coat.
Would removing the membrane have any advantages/disadvantages to applying the bedliner type coating?
Fred, thank you for being so active and involved in this thread. You don't find too many threads THIS helpful!
