Would this work or would it detune the antenna?

Hi Rod,

It would be simpler to just do it and see what happens. The worst
that comes of it is that the metal roof needs the sections
electrically bonded together. Not so much as a "ground plane" as to
reduce corroded connections (by bridging and shorting them) that act
as semiconductors and thus give rise to spurious emissions.

Any elevation removes your antenna from the deadly embrace of lossy
ground.
