[RE-wrenches] Mounting to SIPs, revisited

[Luke Christy]

Esteemed Wrenches,

We have a PV job in the works that will require mounting racking to  
several roofs that consist of asphalt shingles laid over SIP panels.  
The panels are standard 10" nominal thickness, with 9-1/4" of foam  
sandwiched by 1/2 OSB on each side. The rub is that the underside of  
the panels will be the finished ceiling (with 5/8" of wood over the  
OSB).

I found a couple of threads in the archives discussing mounting to  
SIPs, but most comments suggest  through-bolting, and that is not an  
attractive option in this case due to the finished ceiling directly  
beneath.

The roofs in question are triangular in plan, and are fairly small (~  
15' x 15' x 21')

Does anyone have experience with mounting directly to the outer skin  
of a SIP panel?
Suggestions on the best way to approach this problem would be  
appreciated.

Thanks in advance.
