Roof Care and Maintenance suggestions. SEE Finally Update NEED HELP!

I have a 2010 DRV and the roof looks like it is peeling off in some areas. This is a thin layer the thickness of paper or less. Possibly the previous owner put a coating on the roof??? Noticed the peeling in the front corners and some in the far back roof area. Also the roof looks like it has small spots of black mold on top of the roof. Been cleaning the roof with DAWN each year and using a product called Best Rubber Roof cleaner & protectant with UV blocker. I did try using a mixture of bleach and water to clean and kill mold with no luck. Just kind of looks ugly having the black spots on the roof. I called the manufacture of the trailer back in 2017 for maintenance suggestions and was of really no big help other than just wash the roof with with DAWN. I store the trailer outside year around with a cover on it.



Any suggestions? What should I do?

Update as of Oct 6,2020
Called Mobile Suit and asked them about my roof. Mobile Suit RV. DRV recommend calling the roof manufacturer Dicor at 574-264-2699. They might have a higher grade of products for roofs and other RV maintenance products than Henry's. . Wanting for a response.

Just got the phone with an RV retailer/repair shop in Salem, Oregon that has been here for 30 plus years. They said if you maintain a RV roof you should not have to do anything but clean it each year. Said this;if a roof starts to peel, the entire roof needs the peeling remove and completely re-coated. Doesn't sound like a fun job. Also, once this is done, you will have to re-coat the roof about ever 5 to 6 years.

Called an Authorized Mobile Suit Dealer in Oregon today also and they said that they never re-coat any RV roofs and do not recommend it. When the roof leaks of goes bad they replace it. Don't seem like their into doing any real roof repair. Maybe just a very small roof repairs if any and they said to use Dicor product only.

You would think there is straight forward information on RV roof maintenance from the professionals. All I got so far is no homeowner should ever re-coat a RV roof. But Wait! Yes sir you can bring your RV into a dealer and spend thousand to have a new roof put on. Sound like a run around to me!

Finally 10-7-20 : Got in touch with the factory rep from Dicor Products. He told me that within the last couple of weeks several people have call in about questions using Henry's products. His company has a policy about bad mouthing other companies. But; He said that Dicor Roofing System is a two stage process. First step process helps the coating to attach to the final/ second process coating. Rep said Dicor is good for approximately 6 years, Just got off the phone with the Henry's Rep. He said their roofing product is good for approximately 15 to 20 years plus.

So is Henry's Roof coating better of is Dicor Roof Coating?

At this time I do not know the best way to go. Need all the help I can get.




  • Time for some Henry's 887 silicon roof coating. Look it up. you will be more than happy. I replaced the roof once too. Didn't last at all, 5 years. I will never do that again. Get the Henry's 887 Silicon. Its made for RV'S.
  • The cost of the RV Flex Armor is the same as a new roof. No brainer.

    Forget recoating. If the substrate is shown through, it is time to peel off the old roof and replace it.


    Not knowing much about roofs, curious as to know why it should be replaced?
  • I first tried to find a used 5th wheel in the 27 foot to under 30 foot range several years ago. The best I could find was a few Arctic Fox that had a reasonable reliability rating. But for anything within 10 years old, the owners wanted close to the price of a new unit. $38,000 to upper $50,000 plus.

    So, after years of research, looking and many post on the forums I just happen to find a 2010 Mobil Suit 34 footer. The previous owner payed over $110,000 for it and I got it of for $34,000. Yes, It is bigger than I wanted, heavy and sometimes I have a hard time finding a RV site that can fit the truck and RV in to. Need approximately 50 foot space for RV and truck. Had to buy a different truck to haul this RV "SAFELY", 2017 F-350 daully. The old 1999 250 Dodge just wouldn't handle it.

    Besides general maintenance. Now I looking for valve stem extensions, reliable digital tire gauge and a good fiberglass/ protective wax to put on the RV.

    PS: I retired two years ago and I am really to go back to work so I can rest up. Working like a dog around the house! No way I would go back to work in lovely town of Portland, Oregon were no one is held accountable for ones actions. The down town has turned into a ghetto.

  • Wow Chuck. You have one of the few shorter, quality trailers. Probably a keeper. DRV doesn't make anything that short any longer. Anyway, prior to getting my 2014 fiver roof done with RV Flex Armor, all I ever did to any of of my former RVs was Wet & Forget. Spray it on and leave it alone. No scrubbing. I'm done with any roof maintenance whatsoever now, however. Certainly a consideration on your rig.
  • “Been cleaning the roof with DAWN each year”

    Other than cleaning with Dawn, what maintenance have you been doing? Yearly...twice a year...Heng’s coating and EternaBond tape now! Hopefully you got lucky.
