Roof front seam repair 06 Jayflight

I bought a used 06 Jayco Jayflight 27BH and knew there was some previous water damage. There was dicor tape across the front seal, where the metal goes over the TPU roof.

It's hard to understand why anyone would knowingly buy any trailer with such a deteriorated roof, no matter what price it may be, as a proper repair could entail removing the entire roof and starting all over again. :E I'd suspect that tape is Eternabond tape and as pointed out it's TPO (Thermoplastic Polyolefin), not TPU, whatever that may be. :@ For a couple of years around the time your trailer was built Jayco was using a version of TPO roof membrane that later was discovered to easily wick moisture because of the felt backing. This proved to be a major problem for Jayco which subsequently discontinued using this particular version of TPO. Doesn't help you of course, other than to point out that the damage below may be more extensive than you think, and as also already pointed out moisture leads to rot which leads to mold & mildew which creates an environment unhealthy to humans. Unfortunately you potentially have a major project on your hands, not a minor fix. :( Yours is a classic example why to never invest in any trailer with obvious signs of water leakage.
