I phoned the dealer I purchased the unit from and explained my issue. They were very nice and apologised that they haden't thought to check the roof sealant condition as part of my prep. They said that it is standard procedure especially since mine was a left over year model and had been on the lot for over a year. They said they would be more than happy to reseal my roof if I could bring the unit to them so guess where it's headed. I had a couple of other issues that they are going to take care of while I'm there so while it's an inconvience at least I think they have an interest in doing it right.
