Roof rot on Travel Trailer

I had neglected to inspect the roof of my 2008 R- Vision Trail Cruiser 22' travel trailer for several years. Went up on top yesterday.
Besides noticing a cracked bathroom vent cover , all the vents for the tanks were broke off..

Worse was inspecting the front of trailer where the front cover and the roof join.
There is a huge amount of caulk / sealer here. However it had cracked in many places.

The sides of the roof just behind the sealer seem/ edges , they were soft - very soft. Areas were about 6 inches by 6 inches.

I expect the roof is made of wood and rotten from water entry.
Additional the moldings that go up the front corners of trailer and end just past the seam, well they are sticking up about a half inch. Not flush.

It is obvious the white roof coating needs to be cut and peeled back after removing the sealer from the seem. What to expect under there & Is it something I can fix?

Any chance to just let it dry out and re-seal? Not sure how long I will keep the trailer and if it is worth the effort.

I have not seen any signs of leaks inside so far , stains on ceiling ect.
Can not figure how to post pics, asks for a URL but my pics are not online at a site.

  • To do it properly like others have said you need to remove the roof and replace any water damaged decking and put new rubber membrane
    and covers. Just did one last summer. Not expensive if you do it yourself but very labor intensive. If you have wall water intrusion it would be a lot more work. Usually manufacturers recommend checking roof calking twice a year for this very reason.

    If you are not able to do it yourself labor might be more then the trailer is worth.
  • Ins wont pay for lack of maint.
    They wont even pay for something like storm damage if the result of said damage is allowed to do further damage over a long period of time.
  • Water intrusion is a nightmare for RV's.

    Truss replacement in the roof requires removal of roof.
    If the inside is in great shape and no soft floors " be surprised " then maybe it justifies.

    Call your insurance company first.

    Go here and drag and drop the photo from your desktop.
  • To post pics you need to post the pics to a picture hosting website, RVdotnet does not store photos, then you have a link.

    Since 2008? That is a long time to not do service on the seams. They should be checked every year or two, and re-caulked with LAP sealant (never silicone, and almost never use caulk either, LAP sealant!!!!)

    Sounds like you have rot.

    How good you are at fixing will determine if it is worth it. If you plan to sell you should have this fixed, if planning to just drop it off at the junkyard later then you might can get by.

    To fix, it sounds like you will need to find a barn or somewhere to get under a roof.
    Yes, take the entire roof off, replace with whatever they built it with or go one better if you can.

    The plumbing vent covers likely disintegrated from the UV rays.They get replaced every few years because of the sun, unless you store it under cover.

    The roof will not be a fun or easy fix. It might be easier to make that junk yard trip and go shopping for a new or used camper if that is your plan soon anyway. You can spend more than the camper is worth to fix it if you pay someone, and if your time is valuable might not be worth to DIY.

    Me, I would fix, but that's just one person's story.
