dont you have codes out there? how do ya put a fence around that since its within 10 ft of the edge of the roof? Could this just fall if the wind blew? Old grocery stores used to build steel platforms for the equipment to sit on really close to the edge of the roof but that thing is balanced on a knee wall
Now that is a funny picture. The inspector in that town must be a good friend.
Seriously I think you should tell the person whom it belongs to exactly how dangerous that install is. What could happen if it fell on someone.
