temporary rubber roof repair ideas? 95 Fleetwood Elkhorn 11X

The previous owner of my camper did a DIY roof repair on the front of the sleeper and over the bathroom. Unfortunately, he didn’t do a good job. On my way home with it the front roof board blew up in the air from the wind and was stuck vertical. I decided to check the bathroom repair and also not a complete job. That being said, the camper has been covered so the previous damage has been stopped and no new damage has occurred. The front roof board is an 8’ x 2’ piece of 1/4” OSB with thin luan board on top and the rubber roof, which is severely hammered and flaking off. I have previously replaced an EPDM roof on my old trailer, and it came out decent. I learned a lot from that experience. After pricing out what i’m going to need to replace the roof on my camper, I have decided to save that for the future. In the mean time, however, I would really like to make repairs to the damaged areas on my roof to get through the next year or so.

What i’m thinking is, i’m going to go over with a putty knife and peel off the old rubber roof. Take note of any damaged OSB/ply, kilz latex primer for the whole roof, butyl tape all seams and roof holes. Replace front roof sheet and rear roof sheet, Thompson water seal both sheets, kilz primer, and self leveling lap sealant for vents and joints.

I happen to have kilz primer in the garage, some 1/4” ply sheets and luan at work, and I have two tubes of lap sealant. Though, I am considering using some a/c duct sealant instead. I used it on my motor home and went 3 years of heavy use leak free before I sold it, and I have two gallons of it on the shelf, more than enough to seal the camper.

Now, for a top coat, I’m considering a white roll on bedliner. Other than that, I’m not sure what other readily and cheap alternatives there are that will keep me leak free for the next year. Would love some recommendations from those of you who had some good results!

  • There is an elastic paint, mainly used for basement walls. A guy built his own camper and used the paint as the exterior covering. Last word after a few trips was he was happy with it the only downside being it was a bit harder to clean. If you are interested and you can't find it, I can do some digging to try and find his post (may be on this site or the FB truck camper group).

    But if it was me, I would just do the repair right the first time and be done with it.
  • Hate to say it but there's only one way to do the job right and it sounds like you know what that is.
    The Kilz wont do anything to stop water intrusion and that goes double for Thompsons (Worst product of it's type avail). By trying to make stop-gap repairs, your just wasting money on stuff you'll have to tear off later or worse, spending money on stuff that's going to allow severe damage to the rig.
    If you can't fix it correctly now, cover it with a good tarp and keep it dry until you can.
    Sorry I can't give you better news.

    Do it once. Do it right. Do it now.
