Hi Jay,
not having any experience with these roofs (what a weird way to build a
roof) if you're doing a flat or near flat mount, I'd look at the
currrent issue of Solar professional magazine. lots on flat roof mounts.
Ballasted is probably going to be your best bet.
if a high tilt (hot water system? ) I'd recommend either core drilling
thru the concrete/foam sandwich and bolting a pipe leg to the bar truss
underneath. then have a roofer (roofer of record if you can find them)
or a roofer with experience with that roofing system flash the pipe legs.
I'm mostly hot water, and so deal with higher tilts and wind loads than
most of you lucky PV guys.
