Looking at some on-line alignment info, it looks as though for the
Freesat satellite the dish needs to point almost exactly parallel to
surface of the wall, which might attenuate the signal pretty badly
depending on things like possible refraction.

Shouldn't do so. Many buildings have satellite dishes in this
position on the walls.

The point of this idea is to keep the dish off the roof and out of the
way of roof repairers, aerial installers, and the like.

Satellite dishes should not be mounted on a roof. The signal has
come a long way already, a few extra metres make no difference. They
also have a higher wind loading than a TV aerial and are more likely
to damage a roof.
