Have you looked at EcoFastens Eco-65 plate? We used them on a roof similar to what you've got and went right into the 2x6 so we didn't have to go into the structural members. They've got a flashing that will work with asphalt roofs.
Just make sure you get the right length fasteners so it doesn't go through the finished ceiling inside.

The construction is as follows: 2"x6" tongue and groove exposed inside, with 4 inches of foam (blue board) and on top of that 3/4" plywood with asphalt shingles on top of that. I'd like to make a template to ensure that my pilot bit doesn't wander when I'm going through the blue board. If I miss the beams inside, the hole or the lag would be exposed. Anybody run across this? Ideas? I thought of maybe using a qucikmount flashing, with a short section of EMT attached to help guide the bit.... Thanks! Jesse
