Roof Replacement Questions

[khantroll]

Hi all! I am about to rip off my roof and replace it starting one week from today, and I have some questions for the group mind before I start. I had wanted to go with a metal roof, but my finances won't allow it at the moment. So, wood it is.

Questions:

1.) What is the correct size of plywood, 1/4 or 1/2? I've seen both stated on the forums.
2.) What is the best way to remove the old roof?'
3.) Should I put EPDM on top of the roof? I know some have gone with kool seal over wood, but others have done EPDM.
4.) If I do, should it go on top of the kool seal? Or should I leave off the kool seal in that case?

This is on a 1972 Winnebago Chieftain D24-CL.

Thanks!

EPDM and it goes directly on the wood with adhesive made for it. It is a contact adhesive so you will probably want help with the job. I would go with 1/4" exterior plywood but I am no expert. I would think 1/2" is too much weight up high. Do a Google search fo RV roof replacement and you will get several good videos and threads on rubber roof replacements.

Cover alone the roof with EPDM foil is as it were "suicide" W% I did it for two and that was very difficult . If I had to do it again, I would make it four.

I'll let you know how it goes; I'll be using a liquid EPDM coating, as cost comes into play with ordering a white EPDM sheet. The only thing I can find local are pond liners.

Have you tried to Contact Any Commercial Roofing Company's in your area?, as they might have remnants, or a large roll that they would consider selling you the length that you need.  (nothing Ventured, nothing Gained)

I think you will be sorry with the liquid! It is not made to be the primary roof. And once it is on there you will have to start completely over to go to rubber later. Spend it now or spend more later. It's your roof.

Hi Rick! I'm not saying you're wrong, but I just can't afford it right now. I am on a tighter budget then I'd like, and a pretty tight timeline that can't really be moved. This thing has to be water tight and mechanically dependable by the new year. Really, with Arkansas winters, it needs to be water tight by September. The roof is really, really bad, and needs to be done before I can move on to other parts of the rig.


I'm okay with doing it again next year if necessary. It just needs to hold for one year.

Hi Piraterik, no, that didn't occur to me. Do they use the same sort of linings?
