Assuming proper surface prep, dicor lasts for decades. It should never crack, peal or develop any leaks. Again, it requires proper surface prep.
Many assume the sealant on top is Dicor.
I've done all the maintenance on my '97 32' 10" 5th wheel trailers roof since it was 3 months old. Having owned my own RV/mobilhome repair part time business specializing in exterior/structure (years ago) I do a twice a year roof check...once in the spring before hitting the road and late fall when put away for the winter where it sits for 5-6 months.
I've had to replace all roof jacks and fixtures on this unit due to the sun making them brittle and then crack or break.
I use the OEM method when reinstalling...butyle tape as the first line of defense then a self leveling sealant like Dicor over the scr heads and flange edge for the second line of defense against leaks. I never add a tape over any screw heads.
We saw many roofs where the owner had piled sealant over more sealant creating a dam for water to sit (lake effect). Very hard on sealants especially in the winter when it freezing and thawing.
Deciding when to just reseal or replace can't be made over the net or the phone. Each unit will be different than the next. Now if a roof jack or other roof fixture is broken/cracked then of course it will have to be removed and replaced.
