Do I have a roof problem?

Hi Everyone,

I have a 2015 Wildcat Extralite. I was out this weekend, and I got up on the roof to check it out. I noticed these lines of gunk (mold?) seemingly lining up with where the plywood seams are under the rubber.

Is this normal? Or do I need to have it looked at? Thankfully, I have the two-year Forest River warranty that I'm still under.. Just seems odd that there are lines where the seams of wood are underneath.

Thanks in advance for the advice.
Matt

  • I'd just clean the roof with a solution of water, bleach, car washing soap. This appears to be caused by a slight, repeat slight indentation at the seams. then wash the roof annually. Is there only a two year warranty on the roof? Contact Forest River customer support and see what they have to say.

    Some of the answers you have gotten!!:R

    Likely sat a bit seams are the low spot and dirt will settle into them and produce the lines of dirt.


    Does that mean I win? I mentioned the gap between the panels. :B

    Your theory makes sense.
  • My guess is moisture staying in the seem area due to it being lower or cooler. Dirt and mildew accumulating. I don't think I'd put on the haz mat suit just yet. Even if it is mold, how would it have traveled through a rubber membrane to the outside of the trailer?! Good grief.

    Probably just a cosmetic issue. Are the seems a bit of a valley?

  • your ac ducts are leaking allowing cold moisture out and the heat is reacting to it causing mold
  • "Theory" If the sheets of ply are joined together with a metal channel then the colder steel could be causing exxes condesation on the outside of the roof membrane esp in the mornings and therefore causing mould to form along the seams.

    We haven't had the inside tested. From what I can tell, the inside ceiling is dry and not soft.

    I take it from the comments, though, that I should have this looked at. It's been really dry here, so I don't see a reason there should be this issue.

    Thanks,

  • Interesting. Is it possible there was too much of a gap left between the plywood roof panels when it was built?
    The large gap allows more/less heat to build up under the rubber at the gaps causing mold (or whatever) to grow?

  • If you have the warranty...I would not touch it or clean it. Take it in for inspection...take lots of pictures. Seems odd only happening in the seams.
