Roof patio ona row home - good patio coating materials and techniquies.

I own a rowhome in Baltimore city on which I am tearing up a rotted low pitch asphault shingle roof (to low pitch for asphault shingles).  To get something out of this mess I am looking to make a roof patio on the 38x13 foot second floor space, framing out a 1/4 inch per foot slope new roof.  not this deck is over an indoor living space.   I am looking for the mest roof patio materials to use... Duradek, deck king, epoxy paints, epdm, etc....   the one material I seem to keep coming back to is Sani-tred.  Has anyone here ever used this?   AMES research labs seems to have something similar but not quite as good.  I like that pathing in the future is easy (if ever required) , seemless, and that the sani-tred actually absorbs into and bonds to plywood (or many other building materials).   I dont know, for some reason this seems much better to me than vinyl or pvc glued down sheeting with seams.

I am just a DIYer, but maybe this stuff will hep some of you guys in a search for alternative materials. 

I would love to get feedkback or experiences with thsi stuff... If you have any comments on this stuff either post here or let me know at brentlfuller@yahoo.com

If I end up using this stuff maybe Ill try to photo/ video document it and post somewhere.

also, kn the case of sanitred, I am trying to think of the best way to tie to a drip edge or flashing on the side the water will fall off.

Thanks!
