Our daughter and son-in-law are looking into purchasing Liquid Roof by EPDM Coatings. Has anyone used this product? They own a 1987 class C which has suffered some leaking in it's past, and they'd like to put a rubber roof or coating over the WHOLE roof to seal all the cracks, etc. Any advice? Any other products they should be looking at?

We recently coated the EPDM fabric roof of our 38' 98 DSDP with Pro Guards Liquid Roof. It is easy to apply.

It goes on like very thick paint. We thoroughly cleaned the roof, mixed in the activator, poured it right out of the can onto the roof and spread it with a long handle short knap 9" roller. The warmer the wx, the faster it cures. There is more than enough work time.

We bought it online from advancedrubbercoatings.com. for roughly $100/gal

, no shipping, no tax. The website said it would require 7 gals to coat our roof, so that is how much we bought. It only took 3 1/2 gals, so we put on two coats.

We hope this helps

Consider Dicor Elastomeric Roof Coat and Kool Seal RV Roof Coat
Both are much less expensive than Liquid Roof.

Dicor is the manufacturer of the EPDM material used in your original roof, so they ought to know a thing or two about them. And Kool Seal has been in the rubber roof coating business since long before RVs even had rubber roofs.

Hi Born2RV,
Once the roof is coated and dried, consider using EternaBond on every roof seam. Once you do this, you'll be good to go for many years. Go to RV Leak Repair Tapes & Sealants | EternaBond and read about the product. If you use it, consider laying a chalk line on all long runs. One get only one chance to place this product.

...at least some of these replies are assuming the rig has an original rubber/EPDM roof. Is that the case, or is the original roof fiberglass, aluminum, or something else?

But they say in the verbage that it's "not recommended for EPDM Roof" Or am I missing something

It's a 1987 class C - aluminum roof, not rubber. But they'd like to PUT a rubber roof on it, that's why they were considering liquid roof. Can you still use the Dicor?

I coated the roof on my Monaco Dynasty with the rubber coating. I do not remember what brand. I bought it at a local RV dealer for $489.00 for 5 gallons. I cleaned the roof very good and applied with a roller (use a good roller that will not come apart). I brushed it around vents, ACs, etc. I did it because of a few tiny tiny little lines that looked like hairline cracks in the fiberglass. The good thing about the stuff I used is what you do not use you freeze and use when you need to touch up. The only problem I had was it bubbled in a few places around things on the roof and sometime while drying the bubbles popped and created little crater looking holes. I just reapplied over the craters a few weeks after it dried. Rain seems to be a lot quieter too.

You are right about the Dicor product and EPDM roofs - my apologies. The Kool Seal does not have that restriction.

Another product that is recommended for EPDM roofs is Elixir Plas-T-Cote
Roof Coating from Elixir

I have enclosed my car trailer for our move to Texas. I am going to use the sta kool edpm from tractor supply to coat the new plywood constructed roof. Trying it as an experiment to see how it works. It costs about $79 for 5 gallons. Gonna' see how well it does because I'm thinking of using it on my MH after I re- construct the roof.

if the roof is fiberglass or alum and there is not serious damage, a inexpensive coating is PTM paint to metal, Sherman Williams etal carries it. about $40 a gallon and goes on like thick paint. roll or brush.
