Is this a problem?

We have a 2021 Highland Ridge - Open Range stick and tin (conventional) trailer. It has a 3/8” walkable roof deck, although ours did not come with a ladder. I noticed the other day from my stepladder that the roof surface is not smooth. Most noticeably, the seams look terrible although all is intact and well sealed. Whatever is over the seams (under the roofing membrane) is relatively soft and smooth so that part just seems cosmetic.

The other weird thing I noticed is that the roofing surface seems to have an embossed look with the OSB type material surface showing through. I can feel the material texture under it as welll.

This is a PVC roof which is supposed to require less maintenance than conventional or TPO roofing, but other than that I don’t know much about it...

  • clearly looks like the joint between OSB boards, possibly a bead of adhesive/sealant between the boards to make sure they stick together. On top of that, then, lies the membrane, and perhaps a wrinkle in that. This is just guess work, of course, since I have no experience with that make/model roof.
  • “Less maintenance” of any RV roof is a bad idea. Inspect quarterly and preserve as needed. I use Heng’s.
  • I see your point, and would have expected some form of underlayment, but the companies brochure, from their website, does not show any form of underlayment. open range brochure

    They do point to a 15 year NON PRO RATED warranty, so copy that and ensure you stay within their maintenance guidelines.
