Hi all, new to forum. Picked up a 1968 18'+/- Norris travel trailer with metal roof and my first order of business is to stop the roof leaks. Did a lot of research, probably too much, on this forum and elsewhere, and I think I have settled on Liquid Roof as the way to go. So... I came up with this plan:

1. Replace sagging wood ceiling joists to restore crown in portion of roof
2. Clean, scrape, sand off existing coating that is peeling
3. Eternabond webseal seams in metal roof that run across width of trailer
4. Install 2 new roof vents, frig vent and bath vent with new butyl tape kits
5. Webseal flanges of new vents
6. Apply Liquid Roof EPDM coating to entire roof

Guess I should look at edges too and replace butyl tape as needed under trim. Or can I use an epdm compatible caulk to seal edge trim to roof?

Am I creating a problem for myself down the road by applying webseal & liquid roof over flanges and up to edge trim? Is that overkill? Should I install vents/edges after rubber roof is down and rely on butyl tape?

Not going to keep camper forever, but hoping to do the job once.
If I could figure out how to post a pic, I would.

Any critiques, comments or other recommendations are greatly appreciated.

Howdy and welcome to iRV2! Sounds like a great project; wish I had some input for you.

If you nose around here in the vintage section, you'll find LOTS of roof repairs, and hopefully someone will give you some input soon. Good luck.

Norris, now there's a brand I haven't seen lately! Those were some pretty nice trailers!

If you're going to install new roof rafters, a neat trick I learned is to use 2x4's on their side. You start with the full width near the center (maybe the middle 24"?), but cut a taper on each side, down to the original 2x2 dimension at each end? This leaves you with a sturdy "crowned" roof that can carry a snow load or the weight of an A/C without sagging and forming a pool in the center. FWIW, -Al
