One of my competitors has a web site where they promise to inspect common elements (including the the roof, HVAC and plumbing) as part of their standard condo inspection on their home page, next to a pic of a large high-rise building. I know 'cause I took a look when I started getting calls from people surprised I don't promise the same.

I assume that their contact likely disclaims such items (I could not find it on their site). But if there is ever a problem, and someone has that home page cached, I would think they would be in a tough spot, and could be on the hook for the special assessment on the inspected unit.
