My Dad is a different kind of engineer but said in no way, shape or form is a rooftop ever designed to hold that kind of weight. Same with a balcony. How many of the AirBNB / hot tub / deck collapses have you heard about? TONS. I would never, ever, have a hot tub anywhere but on the ground.
Roofs around here are designed to hold a couple feet of wet snow. I'd worry less about that than a bolted on balcony.
