Roof Opinions Please

I just got my truck camper out of storage for 2 years, and the roof looks horrible. It was under a breathable cover, and I've always cleaned and conditioned it with Camco products. The camper is a 2017 model year Wolf Creek 840 that lives in California bay area good weather.

The roof covering looks like its starting to break down, and it's covered in dark moldy looking spots. Is that normal? I hope it's not time to replace already!

The dicor looks cracked, but seems pliable and solid. Is it time to reapply a little on top of the old? Does it need a complete remove and replace? Or does it look good for now?

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.

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.

I thought the roof was covered in a vinyl material. Whatever it is, I'm disappointed that it only lasts 6 years, covered, in a mild climate.

The roof looks like an EDPM material. It has a white layer that gradually sheds off exposing the black substrate. Usually indicates end of life for roof if there is more black than white.
As far s the Dicor, it at least needs a cleaning and another layer to seal it.
Where is the vinyl that you show as breaking down?
