Ok, great picture. First of all you should be talking to a person that specializes in commecial flat roofs.
I would not build a curb against the wall. I would vent that roof as a commercial application. Even if you did build a curb to vent against the wall you would have to divide it because of the windows, which leaves you with an uncontiguous design, leaving some bays unvented. Before I did that I would place the vents in the wall between the window placements and make sure the open bays under the roof extended up the wall a couple feet to the vents.
Talk to a commercial expert (which I am not) and seek his advice on ventilation. I would also strongly consider a EPDM fully adhered application in lieu of torch down. Also note that neither Torch application or EPDM will carry a manufacture’s warranty on residential work. I went to a Firestone seminar last fall and they were talking about possibly offering a residential warranty in the future but I haven’t heard of that happening yet.
Also those windows look pretty low to the deck. That’s always cause for concern and you’ll want your roofer there before the windows are in.
