Wrinkle PVC Roof Repair

[Loganblankk]

I recently replaced the roof on my 2004 Jayfeather but I wasn't able to add the trim to the edges at the same time. Fast forward a few months later I noticed it's all bubbled up and I can just peel it off by pulling.

I pulled it back and reapplied the adhesive to the roof and this time the underside of the PVC for a double sided adhesion. Something I didn't do the first time. After letting it tack up I laid it out, but it's much cooler now than when I originally did it, and by putting adhesive on both surfaces it really sticks as soon as it touches.

Unfortunately this time around it's not flat and there are quite a few bubbles and hard wrinkles in the roof. I'm frustrated because it's a brand new roof and I want it to look nice. But I guess I could live with a semi "ugly" roof since I probably won't ever see it. Only if it won't cause issues down the line.

I don't really want to cut into the new roof, but would wrinkles like this cause issues? Should I wait until it's a little warmer to see if they smooth out? I doubt they will though.

If I do cut the wrinkles to repair them, should I get a air welder and hot weld the PVC or just throw eternabond tape over them?

There are many instances of big wrinkles in brand new rvs right out of the factory. If it was mine as long as you do not walk on the lumps, I would leave it be, forever, while keeping an eye on it.

I don't know much about how to go about trying to rectify this BUT, IF you can't rectify the wrinkles I would opt to keep them as is, vs cutting into your nice new piece of roofing material.

Bummer. That’d keep me awake at night. Out of curiosity, did you have a helper when you re-glued the PVC, or was it a solo effort?
