Whether you will get good results with your loop under the shingles depends on the amount of metal flashing on the edges of your roof. Also, on the amount of metal enclosed by it in your attic. we tried one on a Red Cross building that had perimeter flashing and even on standoff insulators, the loop was a poor performer. The insulators were 5 inches away from the flashing. Perhaps the flashing was the shorted turn syndrome.
A dipole NVIS antenna has worked much better above this particular commercial flat roof. Under the roof were red iron bar joists, which also are grounded.
