Henry Tropi-Cool VS EPDM Roof Coatings

Why did you recoat a 2 year old roof???????? warrantied for 12 years????? it peeled because of improper preparation. No new coating is gonna stay down without removing all the old first. I recoated 2 roofs. First was 16 years old. 2nd was 9.

IMHO, you are quickly approaching the time to peel it off an recover. Forget EPDM. Maximum life of about 10 years. PVC or TPO, commercial grade.

I wonder why you need to coat an EPDM roof membrane. They last 30+ years on a building without doing anything to them.

The RV EPDM membrane itself is typically warrantied against failure for 12 years. What would be the effect on the warranty if you slather on some other product?

Good question. When we bought the sig Class C it had been splashed crudely all over the roof (and here and there on roof things) with some kind of white (ish) stuff. It started to peel off the first winter rains. Big pieces of rubbery skin, exposing the old rubber roof (in bad shape)

RV guy says that is from poor application. They do it right indoors with controlled high temps and are fussy about it all.

So it may not be the different products at issue, but how they are applied. Still, I am hoping to learn more about this too. I have used Eternabond a lot to fight the small leaks here and there as they have showed up in the three years since. Hasn't been that bad, but annoying when it happens.

It looks like one of those cartoons where a guy cut himself lots of places shaving and stuck bits of Kleenex on each cut! :) The RV guy said he would not bother with an overall coating doing it myself or the same peeling thing would happen, even doing it in the summer when it is warm and dry for enough days in a row. So I just keep buying more Eternabond. :)

Still, I would like to cover it all so it looks nice and stays waterproof for a few years. Getting those roof guys in to do it costs more than I paid for the whole MH it seems like. Phooey on that

“But after a number of years it started peeling up.”

That is normal, expected. Sounds like good service. One of the reasons I re-coat every year with Heng’s, a thin coating.
