Look at some of the other threads on this, we have just had a disscussion on some of this.
I hate to tell you this but the glue on the roof or anywhere else, siding, etc. is only covered 1 year. I contacted Keystone about a large bubble in our roof, (Glue not holding) If you look at my notes under rubber roof you will see what is going on. Your unit is a lot newer than mine we have a 2001, so you might have better luck then I am having. I sure wouldn't go any where with it though until you get it resolved. Like the other gentleman said you probally have moisture in there already. Hopefully you can get this resolved before the april showers.
If I can be of any help let me know.
