Don't know what happened to my first reply, lost in cyber space I guess.

Dicor, self leveling sealant , is the product that is probably already around your vent.

Flex seal, I wonder about , long term compatibility, with other roof products, and not interested in being the tester.

RVilini... the two magic products that we keep in our roof sealing kit are Dicor ( or similar lap seal chalking) and Eternabond Tape (or similar brand). You cut the old ugly chalking away.....using a razor knife (carefully) and clean with isopropyl alcohol and a rag....then reapply sealant as alcohol evaporates. If it is a big area of large gap....cover with the appropriate width tape. I think they make the tape up to 8"wide. I keep a 10 foot roll of 4" wide on my rig and use it up on the roof occasionally as my roof is older and needs TLC. If you get in deep need there is a rubber roof liquid sealer that you can paint over an area to seal it.

I think the Flex Seal is fine when you have a leak, and need to try an emergency repair in the middle of a rain.

Dicor self leveling caulk is probably the natural choice when renewing existing caulking.

Eternabond is probably the best choice when attempting to replace caulking to be a permanent repair.
