Roof Opinions Please

Self levelling Dicor is what's used on roofs. It does it's job well. However, Eternabond does it better. And as someone else said, a coating like Hengs or Henry's works wonders. I put Hengs on my rubber roof 5 years ago. It's 19 years old now and looks great. No pealing or other issues.

Thanks for all the input! I'm looking at Dicor now. Do I want self-leveling or NON-self-leveling?

Well our 16 year old roof looked like that 2 years ago, we got Heng’s roof coating. Followed instructions, first scrubbed existing roof with warm water and powered Tide detergent, rinsed well and let dry overnight. Next day applied Heng’s in two thin coats. It still is holding up very well.

Even if the black is exposed, if it is not leaking, it still is working. The worst thing you can do is put a coating on and have it start peeling. That is what has happened to mine, the person before me had a coating applied and it has been peeling ever since. I couldn't coat it if I wanted as I can't get all the peel off. Mine looks ugly, but works. I have asked multiple reputable service centers and they all say don't coat it. Just live with the bad color.

Clean a spot. If the black lifts away then there's nothing wrong with it other than being dirty, which doesn't hurt it at all.

Henry's is good stuff , I've used it on several RVs,

The biggest question: "Does it leak?" If so, find the leak(s) and fix them, . . . now. It's normal to scrape off/replace cracked sealant every few years. Depending on the original roof material, once cleaned, there are numerous coatings that can be applied to your existing roof to extend the life and improve the appearance. Youtube/Google are your friends.

I went out and cleaned the roof today, and it looks a little better. I have cleaned it at least twice a year with Camco Rubber Roof Cleaner/Conditioner and my soft RV wash brush. Maybe I cleaned it too much? Also, I think the cover (which is breathable) allowed mold or whatever to grow, and that's what wrecked the top white layer of the roof. What's remaining feels solid, but just looks bad.

So, I think I'll lightly reapply the Dicor and roll on some Henry Tropi-Cool 100% Silicone coating. Does that sound like a good plan?

Check Utube for videos on RV roof cleaning.
I’d want to kill any mold first, clean it well, then decide if it needs coated.
I’ve heard nothing but great things about Henry’s Tropicool coating.

The roof should not look like that, in only 6 years, unless the cleaning product caused a breakdown, possibly salt water air? The cover may not have been as breathable as advertised? These roof types often carry a 12 year warranty, and can last up to 20 years, in the right conditions.

The Dicor does not look bad for the age, but does need to be cleaned, and a light layer added.

My FW was bought new in Aug 2012. It sits outside, in the midwest year around, gets tree sap, bird cr@p, road dirt, and covered with ice/snow all Winter. I've washed it 4-5 times, added a protectant once. I have added fresh Dicor, as needed, but my roof looks way better than yours.

Something seems to be causing yours to deteriorate prematurely.
