Roofing question
Looking at an opportunity that I think will need a new roof within the next 5-10 years. The seller added new HVAC units for each apartment and they were installed on the roof - on top of wooden frames secured to a pitched roof of a 2-story building. I’ve never run into this before - my hunch is not a good set up (r&amp;m done by crane), roof might have bad penetrations, replacing the roof will be more work than typical).

Anyone have experience with this?
