Roll-on bed-liner roof project
I actually posted this over at another forum after I started the project but figured I'd come over here again and share here too. Forgive me if the wording seems awkward, it was multiple posts on the other forum over a couple of days. Maybe one day I'll edit it and put my stuff on a blog or something but, before I do that, I have to convince the wife to double as a photographer (or at least not laugh when I take them. :) )
I have seen several people express interest in various forums about putting bed-liner on their roof. I have only seen one person with a rubber roof do it, and never saw anything about the long term success.
I did a lot, and I mean a lot of research on different roofing options ranging from completely replacing the EPDM (way too extensive and expensive), EPDM roof coatings (yes, for campers), and bed-liner. I did a lot of pro's and con's and so on but my curiosity and cheapness got the best of me.
I chose to attempt a roll-on bed-liner on top of my EPDM roof.
Sadly, I did not take any photos of my roof prior to the project's start so I'll describe it as best as I can. It was horrible. It was covered in dirt, mold, algae, and God knows what else. After two long and hard scrubbings with Gain dish soap and bleach, I saw my roof. Underneath the filth was a wonderful, barely left rubber membrane. I'd guess that about 25% of the roof was worn through to the black and the rest was almost there.
I had purchased Iron Armor Truck Bed Coating from Harbor Freight for $44.99 a gallon (minus 20% off of course), some regular foam rollers from Home Depot, and everything else I had on hand from previous (and ongoing) projects.
All in all, the first coat took me about 4-5 hours to put down. I used about a gallon and a half of the liner, two 9" rollers, one 3" roller (and handle), one brush, a lot of sweat, and what's left of my pulled forearm (let's just say swinging a 6Lb sledge like a baseball bat isn't always a good idea.)
Obviously the project is not finished, nor do I have any ideas as to how it will last long term but I felt like I would share some do's and don'ts and update the thread as the project progresses.
Tips:
- Don't use rollers for regular paint. I love the light texture it gives, but they DO NOT stand up to the sticky liner. Little parts of the roller are now permanently part of my roof.
- Cover your vents and covers. I didn't and I now have one vent with slung liner on it and a few spots on my AC cover. Good thing those will be replaced anyway.
- Get some knee pads. I already have bad knees, kneeling for that long getting around the vents, edge, etc. just killed them.
- Definitely wear gloves. Fortunately I did because it does not come off skin very easily.
First Coat
-----------
They're not the greatest pictures of the roof, but it's still drying so I had to take them from the ladder.
I wrapped the liner down a few inches on the front and rear, mainly for protection since it won't be black when it's all finished.
Front Cap:
Rear Cap:
Top of the roof, from the front:
Those blobs in the middle are parts of the roller that broke off. Like I said, those didn't last.
Texture of the roof. There's texture, but it's not over the top:
Second Coat
-----------
Apparently I don't write an interesting post, a lot of views but not a lot of comments. Anyway.
Not a huge noticeable difference from the ground but the second (and most likely final) coat is on the roof. I've got to wait a few days to let some rain in the forecast to go through but I guess it'll give me a chance to see if the small leaks I had are fixed or not.
Once the rain passes it will be time for the Gloss White paint to go on and, hopefully, this project is complete.

Texture of the roof. There's texture, but it's not over the top:
I stuck with the regular, low dollar rollers just because I really like the light texture they were putting down. I also found with the heavier second coat it rolled a little easier and didn't rip them up. Also picked up a few more and used one per ten foot section.
I had a few spots on the ends that I hadn't quite gotten full coats on and touched it up with the same brand coating in an aerosol can.
I haven't noticed any bubbling or other damage to the actual rubber roof so it looks like the thin first coat worked out well.
Another thing I had been worried about was the smell getting inside. The one person I found online that posted his bed-liner roof project said it smelled horrible for a month. We have yet to smell anything thank goodness since we full time.
Slide
------------
I still am debating what to do with the roof of the slide-out. I don't know if I want to play it safe and order the actual roof coating or continue with the experimenting with the bed-liner.
The Iron Armor (and a few other bed coatings) don't have any rubber, Kevlar, etc. granules in them. Thinking back to when I was cutting in from vents, etc. on the main roof it laid down pretty smooth. I still have a couple cheap 3/8" nap rollers laying around from the bathroom remodel and I have some wood scraps/concrete blocks to play on. I may take the little bit that's left in the gallon and see if I can get it to apply smoothly since I don't know how the texture, however light, will affect the capability of the seal to, well, seal.
Stay tuned for more updates once the downpours cease.
