There's profit to be made. When in doubt, follow the money. I've noticed that many RV repair services make a bunch of money selling and applying roof coatings which the EPDM manufacturers say aren't needed.

That said, anyone can spend their money and, once out of warranty, can maintain their roof any way they choose. You really do risk getting denied warranty repairs by coating your roof while still under warranty.

Mine too, so as I pondered this all day and talked to hubby, I figured what the heck, its 15 yrs old, no warranty, gray and thin, I'd rather be safe than sorry. I'd like to get as many years out of it as possible.

given its age and condition, I say try option # 1: try the sealer. Worst case, you have to replace the roof which is option # 2 anyway.

Nothing yet, just stopped raining LOL. I am hoping to start cleaning the roof tonight or tomorrow and start coating it on this weekend.

First some questions.

Are you absolutely certain that the leaks are from your "thin spots"?

What do you base the "thin" spot assessment upon?

From my experience and research some EPDM membranes have a layered construction. That means that your membrane may have a white colored layer over a black layer of EPDM. The white layer can get thin while the black layer beneath is still serviceable and water tight. It appears that some RV roof membranes have that construction. Assessing membrane roof condition without previous experience can send you down the wrong path.

Perhaps it's time to get a professional inspection. But who to get? How many RV mechanics or sales people really have experience and can be considered roof experts?

Since you asked, I know what I would do.

Assuming an EPDM roof.
I would patch the "bad" areas using Eternabond tape. It comes in some pretty wide sizes. Be aware that the wider tape is a bit more finicky to apply because it needs to be kept in control to avoid wrinkles.

Why I wouldn't seal coat.

The sealer needs to be applied uniformly and bond correctly. It may bond well, but what if it doesn't? Once you coat the entire roof surface you can no longer properly inspect as the coating tends to hide problems and may interfere with patching even if you do pinpoint the problem(s).

If the EPDM is deteriorated to the point that spot patching is not practical then I think that you really are already to the point of option 2 replacement as mentioned previously. That said, remember that a layman may not be in a position to properly assess the situation.

I do need to disclose that my advice is based mostly om commercial EPDM roofing systems. I have only repaired a few travel trailer roofs to date. The basic experience should transfer though.

Perhaps some other members have experience and a recommendation for a tried and true sealer for an otherwise worn out roof? It certainly is tempting to just slop something on and walk away. Having never even seen your roof I certainly can't make the choice.

well when I can see the plywood under the membrane in the "thin" spots I suppose it needs to be coated or something, and the previous owner has tape everywhere already..if we are looking at option 2 ,..ballpark what does it usually cost,...btw they are a few soft spots on top where I can tell the wood is not good , but has been taped all to hell, but it shows no water damage inside yet,...just saw a seam on roof right under a soft spot that was taped over ,leaking one day after a good rain...

Ok.

That sounds pretty grim. I have no idea as to replacement cost. A travel trailer is relatively small as compared to membrane building roof sizes. You may be able to buy an end of roll, or maybe even properly sized piece of membrane from a commercial roofer at decent price. Proper installation will take some effort and technique.

Sounds like you're in the same boat as I am with my 2001. It is fine for our use, but only worth so much even if it were completely restored. To me our 23b Kiwi is not really worth any grand repairs whether in effort or cost. I did a bunch of "fixes" to deal with the water damage to the wall and floor of my trailer. Fortunately my roof is in very good condition overall. My roof leak was at the right front corner transition from membrane to outer skin. That corner and some other questionable areas were addressed using Dicor products and Eternabond tape.

There were people who quickly recommend dealership repairs or other costly options. I guess even if roof replacement is the proper answer, it doesn't necessarily fit for your situation.

Based upon your added information I would explore whether there are sealants which can be used with a re-enforcing mesh or screen of some type. I mention that because any sealer will only be as good as the structure it bonds to. What you describe with the seam doesn't sound all that stable. A mesh re-enforcement will at least help to deal with some shifting of the substrate. The soft spots don't sound good though.

Another possibility might be to use large pieces of EPDM glued down as patches in the bad sections. Again, smaller pieces of membrane might be available at a local roofer. Contact cement from a home repair box store is probably not up to the task.There is glue which is designed to bond and seal the membrane patches. A DIY option might be to use contact cement for the patch with Eternabond used as a seal around the perimeter. If you use the patch suggestion I would give any corners a bit of radius rather than cutting them square.

Sorry I can't offer more. Good luck. vic
