I’m not sure what the initial question or issue was, but my SteppIR Small Vertical is mounted on my roof with about a dozen radials running from the base of the antenna to various points along the edge of the roof. They are “elevated” near the antenna (meaning there is space between the wire and the shingles) but tend to be resting on the surface of the shingles for much of their length. As to the physics of “elevated,” I think they are still elevated above the earth, touching the shingles or not. Based on my experience, I’d say the recommendations outlined on the sheet from SteppIR are probably pretty good (for what my opinion is worth).

It does miss what they were using for risers. I am not sure if metal or insulated are needed.

It makes sense, but I had not heard of this "partial elevation", so looking for the secret sauce.
