My 1993 bounder EPDM roof has turned black like the top layer has worn off and I was wondering if others have had this happen and what they did type of coating used ect.

If the protective top white layer has weathered away, the roof is technically done.
Some have used a coating that is designed for that purpose with mixed results.
The best (and most costly of course) thing to do is replace it.

About a year ago I restored the roof on our 1996 Southwind. A lot of the white coating had worn off.
I washed it with Tide Powder Detergent and allowed it to dry.
Eternabond was applied along the roof edges. (I previously applied it to the seams)

Then I coated the roof with two light coats of Heng's Rubber Roof Coating. NO primer is needed.
It looks good and is leak free.

The Tide powder was recommended by Heng's.
I bought 3 gallons of Heng's and had half a gallon left when the project was finished.

Our Southwind is 37' long but, the actually roof is 30'.
It's not difficult. I used scaffold for working along the roof edge.
The scaffold is easier than a ladder, but a ladder will get the job done.

I would definitely try to coat the roof before replacing it.

Like gbopp said. There are other brands besides Henry's and I would just go with what ever brand is available at your local big box hardware store. Some are even labeled RV Roof Repair EPDM.

I used a different brand on my 5er roof that was 10 years ago and the only leaks were on places I did not use the EPDM paint. I can not remember the brand, but it was on sale at a Do It Center for 50% off so I bought it.

I have used Henry's since then on other projects to waterproof everything from fence gates to boat hatches and it is a good product.

Liquid roof $80 per gal

Superior roof coat white, for Edpm and tpo $80 per gallon

Kool seal liquid roof coat $75 per gallon

Henry's #587 elastomeric roof coat white $30 per gallon

Each one covers at a different thickness and different number of square feet

Between 40 SqFt to 100SqFt per gal bucket

30ft roof will need 6 or 7 gal of liquid roof per mfg directions

While Henry's will #587 will use 3 gal per directions

Henry's also had anther coating that is listed at 42sqft per gallon and $54 per gallon

Prices approx, will very a few $$ per seller

Liquid roof, and Superior are two of the best , that I have used, of all the ones listed, and i have used all of them

Use either one and never redo the food unless you damage it
