Roof replacement- what would you do?

[1moproject]

I just bought a 94 Prowler 24' TT to use in my business (restoring old houses) and need some advice. The TT is in good shape with one major exception- the roof! The P.O. removed what I suppose was an EPDM rubber roof and the unit was reposessed before he could replace it! So I'm left with nothing but bare osb up there, currently covered by a tarp. I need to get this thing back into service asap, and am wondering how best to proceed. There is one corner of osb that is soft and will be replaced. The a/c unit and all of the caps, vents, etc are off of the unit. (I do have them.) Should I purchase a new roof "kit" and just roll new roofing on, since half the work has been done, or can I purchase something like a "liguid roof" product and use that? I don't care how it looks, or about resale, but I don't want leaks. Any advise you can provide, including reputable suppliers would really be appreciated.

This depends entirely on how much more money you wish to invest in this trailer. Coating a flat wood roof so it is waterproof is difficult. If you are going to do the work yourself, which I assume you are; the cost to install a EPDM membrane will be around $700, I think. Then there is having the wood covered by "rhino-liner" or similar bed coating. I would assume covering the roof with aluminum would be costly today, as scrap aluminum is just over $2 a pound. That would make new sheet aluminum costly too.
I know nothing about this DOW Sprayed RV Roof compared to EPDM Roof Coatings. but it sounds good.

Thanks for the reply. The answer is not much, and yes I will be doing the work myself. Has anyone tried the rhino-liner approach? If that can be applied directly to the wood sheathing, that sounds like the way to go.

Since your in the construction business talk to some local commercial roofers, I got a scrap piece of EPDM 12x45 for free! Well case of beer anyway. It was leftover from a drive thru portico job. Looks like I'll end up spending a couple hundred more in supplies.
