does anyone have any insight to recovering a rubber roof? do you have to pull the old one off? if so is there an easy way? can you just get some type of primer and lay a new one over the old like patching an intertube?
who left the light on? is it me or are we leaning downhill. where did the dog run off to

Golden,
Yes-No-yes-yes.
EPDM Roofing/rubber roofing can be purchased at a Roofing Supply House. It is in 4' rolled sections. I would first consider flood coating (Look in CW website for the gallon type fllod coats available)and maybe piece patching bad areas first, yet if it is heavily deteriorated with cracks greater than 1/8 inch then look towards entire membrane replacement. I would not tear the old one off, since the plys are very light and are applied with adhesive, As long as you do not have moisture trapped within the existing rubber roof, you will be fine. Overlap should be 2" on each run.

the whole roof is like worn out,the white is dropping off leaving black showing, the last time i tried a coating, it just eventually started pelling off also into the second season. i do have a hard time finding a 24hr dry window, even if no rain the dew seems to lift it up also. so anyway it's one of the first yrs they went to the rubber 1994 so i was thinking i mite be better off w/complete recover?

Check out this link:
http://www.jnkproducts.com/liquid_roof/
Then search this forum for Liquid Roof comments. Everything from everyone I have seen is positive.
Also this product is sold at CW for $90 plus tax and shipping, the company at this link sells one gal for $60 no tax and no shipping.
Good luck.
Show me the GRILL and STAND BACK!!!!

Just started re-coating my roof. It is not a rubber roof. It is aluminum. However, there had been numerous coatings put on. A small leak occurred, and I had to take some action. Living in Seattle, I have moisture issues as well. I decided to recoat in segments, one-third at a time. I took a wild guess at where the main problem was and started there. I removed all loose material, pressure washed and degreased the area to be recoated, and then let it dry in the sun for a day.
I am using the liquid epdm referred to in previous posts. It is a two part product- the rubber and a catalyst. The kit comes with a paint brush and a paint stirrer for a power drill (use a plug in drill-I ran the battery down on the cordless and then had to switch--may not sound like much, but the rubber is really gooey). Don't put the stirrer all the way to the bottom of the can. If you do, and then pull it up, you will fling liquid rubber all over everything in a small radius. I had good luck with the stirrer about two inches or so below the surface. The aim is to create a vortex that you can then pour the catalyst into.
If you decide to go this route, buy an in-expensive rubber edge squeegee device. I used the supplied paint brush for the first half of the can, and about wore out my arm. I had an 8" plastic edger on hand that I used for the second half--it was much more efficient. Pour the product out in a ribbon that will let you work about two square feet at a time. Work the squeegee/spreader back and forth and the product lays out nicely. The product has a six hour work time. You can lay the gallon in about an hour. One gallon covers about a 8'x12' section. It is self leveling, and you can use the paint brush to work the product into corners, around ladder posts, etc. You need to wait about two hours before you come back and do touch-ups. If you have a little left over, the manufacturer claims you can put it in the refrigerator or freezer for later use. ( Obviously, the manufacturer had not discussed that option with my wife ) Had first rainstorm last night---so far, no leak. Good luck to you.

Hi, I just sent our 89 to Longview RV in Mass. They are replacing my rubber roof (89) and rebuilding the nose. The roof was flood coated 18 months ago and had deteriorated badly The option of an Eternabond overlay was not a good idea because the cracks had reappeared through the flood coat and it would require sealing them again and the odds of the Eternabond not holding securely was present. The end result is do it right or cut the camper off and use the truck as a flat bed hauler. My wife said keep the camper, so it gets a toupee and nose job. A lot of money, but we're very comfortable in it and to replace it at our stag in life is nuts
Happy Motoring

Thanks for the very detailed explanation. That will be a BIG help to me as I have two gallons in the garage that have been waiting for good weather. I have the same roof as you and the same type problem. I am preping this weekend and will apply soon. Thanks again for explaining so well.

Has anyone considered a sprayed on "bed liner" type coating of
their aluminium roof? Anyone done it? Might be too brittle...

Old dog I am "Topeka" the one refered to about roof coatin - Just haul it off to the Line-X dealer an have it coated. if interested I have pictures of ours which is a 1985 Jamboree 29 footer. This unit lended itself rite nicely to the stuff. We have a horizontal raised siding member about 2 inches wide that runs the length of the unit making it an ideal place to roll the coating over to. They ran it bout 3 inches forward of the seam where the aluminum met the fiberglass nose and same in the rear. Exceptionaly neat job. We had remover the A/C and they worked around an up to all other vents etc. For 800 bucks - I am exceptionally well pleased.
If you respond to our e-mail address - be absolutely sure to make subject sumtin refering to RV roof as we have programs that only allow certain items in to mail box. All other e-mails go to a bulk holdin box that we check daily an if sumtin stands out we open otherwise all is dumped with 1 click... jpmac1@cox.net
