Alan,
Thanks for the correction, I did in fact use the blue 'roof grip screws' with neopreme washers provided by DP&W for use in OSB. I better go chug more Ginko.

Just a note of caution here: "Tech" screws are "Tek" screws, which are essentially a sheet metal thread following a pilot drill point, on a hardened shank. They are intended for mounting only into metal, not wood; the drill point isn't designed to self-pilot into wood, and the drill section is too large in diameter for wood.

Luke,
Direct Power and Water has an optional mounting foot with five holes in it for what I think Jeff Randall there referred to as 'Tech' screws to use in the field between rafters. They are referred to as 'easy feet'. It is designed to only attach into the roof decking, which I'm pretty sure only required 1/2" OSB. He claims the same or better pullout values as one lag per regular foot...there may also be tighter spacing involved for the feet. The choices are 1 1/2" or 3" long, has a self tapping point so no pre-drill. Add some of the peel and stick mastic and it's a fast install.

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.
