I know a city in California with the heat exchangers on the roof. Do you have any idea why? (The properties were large enough the footprint wouldn’t be an issue.)
Where I am in the USA Midwest the heat exchangers are all on the ground as they are easier to install and maintain.
A lot of newer homes being built (at least in California) are putting them in the attic or on the roof.

Looks and maybe energy efficiency (if done correctly) would be the biggest reasons I can think of.
