Best Roof Coating

I am not an RVer who needs a blinding white roof and the Heng’s on my roof now is a second coat. Neither the first or second has cracked, peeled etc. No horror story here.

My vote is for Heng's Rubber Roof Coating. It goes on easily and needs no primer. Just wash the roof well before applying. I used 2 1/2 gallons to cover 30' of roof with two light coats.
Heng's holds up well.
Use Eternabond and Dicor Self Leveling Caulk for any seams or tears in the roof.

Define "HOLDS UP WELL".

1 yr??
2 yrs??
3 yrs??
5 yrs??
10 yrs??
15 yrs???

Is the "HOLDS UP WELL" just the "pretty blinding white" factor?

If so, blinding white does not equal "HOLDING UP WELL"...

It can look pretty and white but if in the end it cracks, wears thin or peels off or you have to reapply again, it failed to "HOLD UP WELL".

RVrs seem to be totally obsessed with having a "blinding white roof" and are willing to spend a lot of time and money on keeping it blinding white.

Slathering things on that roof also does not add real life to the roof, just prolongs the obvious issue a couple of yrs.. If you are really planning to hold on to the RV, fixing old cracked caulking is best plan than worrying about the color..

You don't see home owners painting sticks and bricks roofs, not sure why RVs get so obsessed with perfect white roofs.. They will get dirty, they will go grey to black as the roof wears and even if the roof goes 100% black as long as it sheds water it is 100% functional without slathering fixes in a can on it.

What problem are you attempting to fix?

Your gonna get a lot of opinions..

I tried Kool Seal, looked nice, lasted less than one yr and started to crack and look thin in places.. by yr two, it was pretty much worn off..

Yes, I cleaned, scrubbed, prepped and no it didn't last.

In my case, I applied over a worn fiberglass roof, applied several coats.

I will be very frank and honest about these liquid fixes in a can.. They are very temporary at best, and will require reapplication often.. They are as thin as paint, you simply cannot replace the thickness of the original roofing material..

If your roof has no rips, tears, cracks and it just doesn't look "pretty white" anymore, DON'T DO IT! Don't go there with liquid in the can fixes, you are just wasting your money and time.

Your roof DOES NOT "have to be blinding white" to still function and absolutely nothing you can slather on it from a can is going to preserve it or give longer life.

If your roof has some rips, tears, cracks, DON'T DO IT! The liquid fixes in a can will not have enough body to bridge and repair those issues and will fail.

In my case and NEW roof over top of the old fiberglass was the only real fix because of cracks in the fiberglass that just defied staying repaired and the high cost of automotive grade paints being out of this world in cost.

I’m happy with Heng’s.
