Andrew:
For years we used the tap test to get close (hammer gently on the roof, listening for solid sound. Move up and down a course or two if needed.) After the tap test, we drill a 1/8 hole and inserted a bent landscape flag wire and rotate it, feeling for contact with the side of the rafter. Then someone improved on the idea and invented the tool linked below. https://wizarddistribution.com/index.cfm?fuseaction=product.display&product_id=4168&ProReview_ID=663 This has proven to be a great tool. I highly recommend it. It still requires the tap test to get in the general vicinity. BTW, everyone on the crew has their own color of lumber crayon used to circle every pilot hole to indicate they own it. This really encourages being responsible to ensure the pilot hole is under the flashing and gets sealed. If a pilot hole is drilled that will not be covered by the flashing, we take a cut off upper shingle tab and slip it under the course with the pilot hole and squirt some caulk through the hole. 35 years in the industry and only one roof leak.

And it still wouldn't get you closer than a hammer. Also, most attics are ventilated so they would be close to the outside temp anyway. Usually the insulation is on the ceiling not under the roof. On a cold night with a vaulted ceiling is the only time it "might" work.
