You wrote, "Foil-faced roof sheathing would only be successful at reflecting heat developing from the home, not at trying to keep warmth from the roof masking from entering the attic due to the fact there is no air Area in between the shingles/plywood as well as the foil."

To get productive, the reflective surface will have to face an air space. Dust accumulation around the reflective area will decrease its reflective functionality. The radiant barrier needs to be set up within a way to minimize dust accumulation to the reflective area.
