Butyl tape can be very effective in roofing applications but you need to be very careful with the tape you chose. Not all Butyl tape is created equal and some are incompatible with common RV roofing materials.
When it comes to things like roof vents I say just cover the edges completely with something like Eternabond tape. It's easy and very effective.
