I am assuming that the caulking that in the pictures is the self leveling caulking from the factor. As you can see it is in bad shape. Whatever it is it peals off very easily so I do not want to leave it on. My question is the eternabond tape all that is needed to reseal after removing the factor caulking? The rubber roof is in good shape so is it necessary to coat the roof after applying the tape? Thanks for any help.
