I agree with Bob. I have seen numerous YouTube videos lately about running 4" or 6" eternabond tape down the sides of the trailer as a preventive against damage. I chose to just reseal with Dicor non leveling lap sealant instead. Eternabond tape works very well for a repair, but running around every opening and edge of the TPO roof as a preventive seems overkill. If water does get behind it, removing the tape would be much more difficult to actually repair than just replacing/repairing the lap sealant.
