Since they're likely to be stuck with HOA rules about exterior
appearance, solar panels on the roof are probably out, but they were
wondering about simply running water pipes through the roof space.

Does this have possibilities?

You're better off with point of use electric demand water heaters. They
are only$150 and only run when you actually use the hot water. One under
the kitchen sink and one under the bathroom sink and shower. Will work
fine in the shower if you are not a water hog and use super saver shower
head with reduction valve. Not recommended for tub or spa bathers or
other water wasting devices. As far as preheating you can put a large
cold water holding tank in your furnace room or in a closet in the
living area. That will keep your water at room temperature.
