I like Eternabond and have been gradually replacing caulked seams with it. Now, after 15 years the rubber roof itself is starting to go; the white is wearing off in places and the black shows through.

They make Eternabond in 12" widths and even wider. How about I cover those spots with wide Eternabond strips? And as the roof continues to age, cover those new spots, etc., until eventually the entire roof may be covered with overlapping Eternabond?

Advantage: I can do it gradually, and it is within my skill level. Replacing the entire roof is a huge job, lots of upfront cost, and I would probably screw it up.

MY take on this is -

Why place a band aid on something that needs fixing ? The money you will end up spending in the long run will be FAR GREATER than doing it right the first time I think..

I know that I have purchased 6" x 25' rolls and have paid $50-$75 per roll..

Sure it would work, I guess..??

Clean the roof and coat it with something like Heng's Rubber Roof Coating.

I restored the roof on our 1996 Southwind. After applying Eternabond to the seams and roof edges, it took 2 1/2 gallons of Heng's to coat 30' of roof with two light coats. It's easy to apply and does not need a primer.

solis, I see your point. The last 2 TT's we bought, and now our new C, first thing I did was buy a roll or 2, and cover ALL cut openings in the roof. Around skylights, vents, antenna, etc. Even though there is caulk covering the screws and such, I feel better after a bad leak some years ago. We always seemed to have issue with the cap meeting the roof (last 2 TT's) as far as leaks go. Yeah, it's probably expensive to do but I guess it would work.

I agree with the others that thought should be given to doing the job right (roof replacement) but it sure seems there has to be better way to do a roof.

Ditto on the Hengs. Probably not a permanent fix but good for several years anyway. I used it on our old fiver, it went on easily after I cleaned the roof. I think I used 2 gallons on a 35 ft fiver and that was for two coats. You get a nice smooth white finish no brush or roller marks.

EternaBond can be ordered in a roll that is four feet wide.

If you look at a cross section of an EPDM roof it has a very thin top layer of white, the substrate is black. The white top coat will slough off do to sun and rain showing the black substrate. 15 years is not old for an EPDM roof, I would not replace it unless there was severe damage. Coating it will return the white color and make it cooler inside and protect it for another 10 years before it wears off. My roof is 23 years old, I coated it with just one coat of acrylic coating in 2007 and it is wearing off. When it all wears off I may coat it again. The roof has never leaked.

Purely cosmetic, you don't have to do anything with it.
