Is my roof an EPDM roof (pic included) UPDATE

I recently picked up this 1990 Damon Escaper Ultrasport. The material feels like rubber but I don't know why someone would leave it black. I want to cover it with liquid rubber (white) but want to make sure what type of roof I am covering.

  • I would take off a vent ring on the inside and you'll see the roof material (or should) tucked down inside the hole. Snip a small piece and take it to someone that could id it along with pic's to ID exactly what you have. Believe it or not EPDM is just not for RV's. I don't know if it is any thicker or holds up better, just saying it could be EPDM. Mostly used on roof buildings. Made link to google pics on EPDM roofs, see how many are black?
    If it is EPDM going to be better RV in colder climates, of course hotter in summer. https://www.google.com/search?hl=en&site=imghp&tbm=isch&source=hp&biw=1366&bih=620&q=epdm+roof&oq=epdm+roof&gs_l=img.12..0l8j0i5.4136.6973.0.9812.9.9.0.0.0.0.57.471.9.9.0....0...1ac.1.26.img..0.9.469.z0wz33eEfJEIf it is EPDM and you don't want to change it out or need to do maint check out http://www.inlandcoatings.com/rc2000.htm great stuff. Brushable, rollable and plyable and if you don't want your roof black paint it white. I really like it, been using instead of RV "quality" chalk for several years now. But I don't like the price and I can only it get by the gallon. Retail of $125.00 but called around and I can get for $87.00. Equals out just about same price as other caulk, but I usually end up tossing out about 1/2 because didn't use up.

    And to get up old junk off I use a solvent cleaner.
    http://www.wlsheadliners.com/acry-solv-solvent-cleaner-and-adhesive-remover-aerosol-can.html Squirt on and wait 15 min and scrape up with old rag, let dry maybe 10 min and apply RC 2000. Most of RV folks would never do this. I learned this from the someone that takes care of a large RV rental fleet and that is how they did it. Acry-solv is banned in some states because "VOC content 100% by weight" So Yes if you need a solvent, I would say 100% is pretty strong (good IMO). Read MSDS paperwork if your that type of person. Has about as many cautions as "sani-flush" To get it tinted I called, Inland Coatings, they said tint to "855 or 844 Victoria series" at any standard brands paint store. I just walked in with a little piece of my King of the Road roof, sort of camel color and they matched it up pretty good. To be safe before use (IMO), take that small piece of your roof that you matched up material with and squirt it to make sure it doesn't eat it. With me it has replaced Pro flex which replaced Dicor caulking, which replaced Camping Worlds "self leveling" caulk. Many will not agree, but has worked great for me. Very nervous the first time. Brushes on like OH boy know I've blown it, but dries like a dream and lasted longer than the RV off you get off the shelf stuff. Disposable everything (brushes, rollers etc) unless you like cleaning forever with mineral spirits. Hardest part of mine was getting A/c out and back in.
  • That's black EPDM its about half the cost works exactly the same and will last just as long. I would paint it white to make it cooler I believe Henry's makes a compatible coating for around 100 for five gals.

    Did your roof look like this? I don't want to put liquid rubber onto a surface it is not designed for. Thanks for the input

  • So it is not a standard rv roof? Makes me feel a little better not knowing what type it is since it is not standard. It is in great shape and no leaks. I just don't think a black roof is ideal.

    Would you guys want it white? Not sure how liquid rubber would adhere to it.
  • Doesn't look like any coventional RV roofing fabric from that era. The EPDM fabrics were white to light gray, TPO almost always white, and both one piece so as to not have seams in the fabric itself.
  • Looks like a previous owner recovered the roof and used the rubber material that they use on buildings. I would contact a roofing supplier in your area and check with them.
