Liquid roof.....so many reviews, good and bad

OK, spring project. Recoating EPDM roof with liquid roof, in particular, the one offered by EPDM Coatings. I've seen great reviews on this, but also some bad ones that never really mentioned the exact product used. I know, Lowes and HD has coating. I'd rather use something that is specifically made for RV's. Does anyone have experience with this?
  • We used the Liquid Roof from EPDM. While it did do a good job of sealing the roof, in short order the surface turned splotchy gray and looked as bad or worse than before we coated. Keep in mind that it is only the looks and the actual material is still sealing the roof. The manufacturer refused to acknowledge the problem or do anything about it. This was 2 years ago. We did the coating, not because of leaks, but a precaution on an 18-year-old roof that has no leaks at this point. We are very disappointed in the appearance and how the manufacturer has NOT responded. I seriously wonder if they will stand behind the product if there is a failure since in our case the "Warranty" means nothing. The splotchy surface issues began within a matter of a few months and to this day continue to get worse. At this point, the previously white roof is now covered in gray and darker areas all over.

  • Liquid Roof is one of the best

    i have used it before on previous RV, and will do so again if needed for this one
  • I just chalked mine and cleaned. Put tape on an old rotted spot on roof as reinforcement. There was a leak one time and 4x4 corner of roof rotted below the redpm...

    I only did front and back quarters, and edges. And all vents, skylights, antenna. etc etc... All with one gallon..

    This coating does attract a black type of dirt.I sold the trailer but it washed right off. This was after winter storage. Where the factory edpm did not have this black dirt...

    Mold? IDK...

    But I gotta say they stuff worked great... You can get a 10 year warranty if you put it on a certain mil think I believe...

    I was just happy I didn't have to caulk anymore...















  • That looks like the stuff that I used on our previous camper. I also used eternabond on the edges and roof penetrations. I was very happy with the results.
  • Yes, ok, did our 2003.
    Clean off roof and old caulking.
    Removed dicor on the outside edge.
    Then used eternabond, 4" x 50' rolls around the edge.
    I used a roller brush, long handle. Front to back. Pouring from a red solo cup.
    Came back next day repeat coating.
    Came back next day repeat coating
    Came back next day repeat coating.
    In all 4 coating from the 4.7 gal bucket.

    And by the way sunglasses were needed, and I did it in my stocking / socks.
  • I was looking into the Henry Tropi-Cool from Home Depot. I have a 2002 Georgie Boy Landau and heard it was decent stuff to use. Just rinse off the roof and make sure there isn't dirt, leaves, and such on there, then roll paint on the product.
