The first picture just looks like mold, is that okay relatively speaking ? what should I do with that ?
the second picture it looks like a chunk of the roof is missing just below the round think on the roof ?
the third picture it looks like the eternabond tape came loose and is peeling off ?
Backgroun: 2003 forest river travel trailer. I have owned it 3 years. I did all the eternabond 2 years ago. 2 years ago everything looked pretty good, there was mold spots but not nearly as much
What I really want to know is, this an emergency and I should bring it to the dealer ASAP to get fixed before all my walls and roof rot away ?
Or is this just something I should work on and really no big deal ?
The camper is 90 miles up north, and the soonest I can get to it is this Satureday, the roof has probaly been like this since this spring. ...
If that is a chunk of roofing material missing, that is not good. If it is exposed to water, you should likely peel back the rubber and inspect the wood roofing below to make sure it isn't rotting. If it is, repair the roof decking before doing anything else. Liquid Roof is a pretty easy (but somewhat messy) way to patch EPDM roofing material. It is a 2 part liquid that you mix and apply to EPDM roofing. The Liquid Roof is literally painted on with a brush or roller. It adheres to the existing EPDM and dries to a seamless EPDM rubber. Its easy to DIY and does not create any seams. You can even recoat your entire roof for a couple hundred dollars.
If appears as though the Eternabond did not stick properly. I would cut off the loose portions, thoroughly clean the area and attempt to attach new Eternabond again. Remember that Eternabond requires pressure (like a roller) to ensure a good bond to the roof.

I have a reoccurring area that requires some of the self leveling stuff every couple of years.
.
If you have signs of water in the ceiling inside, and if the roof is mushy, then you've got water damage, and a trip to a repair shop might be in order to determine the damage.
One possibility is to buy a moisture meter, if you have more than 20% moisture you have a breading ground for mold.

what do you guys mean by "clean" the roof ? I was going to spray the spray that comes with the Eternabond tape, wipe the area down good with a towel, then lay down eternabond ...
should I actually "wash" the roof or does that do more harm then good ?
Also I don't think that's mold that's the roof wearing away ? then how much life does this roof have left in it ? 2 years ? 5 years ?
what if I Eternabonded the entire roof ? does that make sense ?
Those pics are proof that some people should stay away from eternabond. It was either a bad batch, or terrible surface prep. Looking at how sloppy it was applied, I lean toward terrible surface prep.
Pic two, is that a hole in the rubber, or is it a drip of dicor or? A short piece of eternabond over that and it will be fine.
Remove as much of the loose EB and reseal with dicor or more EB.
Or, if that is white peeling off the black rubber of the roof, you may as well plan on having a new roof installed.

1. Keep your roof clean. Clean your roof at least four (4) times annually(Probably way over due with your roof).
For normal cleaning:
- Use Dicor Rubber Roof Cleaner RP-RC160C concentrate to clean complete roof or RP RC320S ready to use cleaner in a spray bottle for smaller areas.
- Rinse complete roof with clean water to remove any loose dirt or debris.
- Using a medium bristle brush, along with the cleaner mixed with 2 or 3 gallons of water, scrub the entire roof. Rinse thoroughly with clean water to avoid residue build-up on the roof or sidewalls of the vehicle.
- For more difficult stains, you may use RP-RC160C in its original concentrated form. For stubborn stains, use a cloth dampened with mineral spirits. DO NOT use mineral spirits in a large area or allow it to soak into the membrane.

Why do we have to push 1 for English?
This would be a good candidate for a pressurized leak test. There could be other leaks you don't know about too.

The dealer said about $2600 for new membrane, without seeing the camper
I put the EB on myself, 2 years ago. I used the spray that came with it, and wiped it down with a towel. That is all I did.
If I did not prep the surface good enough, can you please tell me how to do it differently ? any help is greatly appreciated..
Also, I am going up to the camper this weekend, is there an easy way to determine if I have water damage ? or what should I look for ?
thanks for all the help so far everyone!
2. The spray is a great cleaner. I use acetone because of less cost involved.
3. Plan/map out how you want to lay it down. In my case, I trimmed and removed excess dicor so I could get a complete adhesion on both sides of the joint. I used 4" wide tape, and lapped over joint all the way into the gutter.
You either had a bad batch of tape, or improper/incomplete surface prep, or just didn't lay it down/adhere it properly (requires a roller to make sure it is adhered). Assuming all tape laid down at same time, and that's the only place where it's peeling, I'm going to go with improper surface prep or not adhering it properly after applied. Stuff is crazy sticky when adhered properly.
I also tried to avoid having short pieces when covering side seams. I ran one piece the entire length from front to back, and one piece side to side on each end.
I would remove the peeling tape to the point where it is adhered good, and replace.
Look for soft spots in roof, or soft spots inside, moldy smells, water staining in corners, at floor or at ceiling.
Hope this helps.
Those areas that have peeling Eternabond need to be fixed. It would be better to remove any dirty, failing caulk than to assume a quick spray and wipe is going to make everything ready for Eternabond tape installation. I've used a few types of their tape and don't have any peeling areas like that. The trick is to get everything "Hospital clean". Use soap and water, then solvents (like the prep spray), to get the area to be covered scrupulously clean. You are rolling the tape after applying?
Those black spots on the roof look real typical of the molds and algaes that grow on roofs in Northern MN when the roof is under trees. I've replaced shingled roofs in those same locations. The ultimate cure for roofs in those locations is to install a sacrificial zinc or copper plate on the roof so the oxides of the metals kills the algae/mold. On a travel trailer, that is going to be problematic.
I would advise anyone buying a used trailer or anyone owning one with a questionable roof, to do a interior pressurized leak test. It will uncover even the tiniest pinholes.

There is also RV Armor (search for that term on this site, there is a thread where Edatlanta got it done and loves it).
To me, $2600 to replace the roofing sounds like a pretty good deal. The dealer would have to remove everything (AC, vents, skylights, etc) from the roof and get it down to bare wood. They would be able to determine if any leak caused structural damage and fix it at that time. Then you would get a new rubber roof with a 12 year warranty on the roofing.
