I just noticed the white coating on the rubber roof appears to be deteriorating, it has become gooey and sticky.
I can scrape the white aside with my finger nail quite easily and expose the black rubber underneath, the roof does not leak.
Has anyone had this happen and would a roof coating like kool seal or a similar product bond to the gooey coating on the roof now.
Any info would be appreciated.
Thanks

Just finished our RV roof myself,I used the 2 step Dicor Acrylic coating
after removing all vent covers plus a/c shrouds
First step was the cleaner/primer then light power wash, let dry few hours, the whole process has to be done in one day
I put on three coating during the rest of the day ,2-3 HOURS APART
if you plan on doing it yourself,after the first coating, remove you shoes and just have bare feet or socks, the new coating marks pretty quickly so far it looks really good
You can get it in 1 gallon or 4 gallon pails, 4 is probably more than enough for a 30' RV. It will not flake off like the original coating, so no more white streaks.
The single part coatings, well I was not to happy with those. I think it was Kool Seal or something like it that disolved when exposed to constant water on the roof of my old camper. It was fine as long as it dried out every few days, but when a low spot was underwater for a long time (in Washington), well it disolved back into it's water based formula, and let the water right in.
The product above is a two part - with a catalyist, so it will not come apart once it drys. There is a video on application on RV roofs on the website.

i think this is the same stuff i had mine covered with if its the same thing you have to mix a two part mixture and roll it on with a paint roller mine has held up 2 years and counting cost was around 400.00$ for every thing
Mine was in good condition but I decided to coat it anyway(belt and suspenders). I used Kool Coat or Seal from Camping world and it's been on 5 years now with no peeling. You must follow the directions. Wash roof, apply primer and let dry, then two coats of the Kool Coat letting it dry between coats. I even put it over the adhesive and it worked. Like fred says no more black streaking. If mine fails then Im going to go with Fred's idea. Mines a 96 and no leaks yet.

We just had our roof done by Minnesota Roofing & RV
www.rvroofing.com (don't know how to do a link) You can either do it yourself or have them do it for you. I would suggest you have something done before you have a leak. That will just increase your money output. Roof looks great.
Thanks for all the info.
The camper is a 1994 vintage.
I cleaned the roof and removed and replaced all the old calking just last year and it looked pretty good when I finished.
I was amazed at how much the white rubber coating has deteriorated since, in some places it is like goo.
There are some spots that were covered with caulking until I scrapped it off, those areas are like new but where it has been exposed to the Florida sun for years I guess it took its toll.

I would consider using a fairly thin sheet of aluminum laid right on top of the rubber and securing it along the edges, front and back and maybe a could of other areas with screws covering all areas with Eternabond. If you do that before you actually have leaks then you basically have dual coverage and things like branches, etc. aren't such an issue.
