EyeofRa,
I saw a video of a person lifting a few water bottles with his drone.
Perhaps you can convince another drone pilot to help retrieve your drone by connecting a hook and line to their drone ... and grab your drone off that roof? A Mavic will weigh a lot less than a few 500 ml bottles of water.
check it out on YouTube... There's this insane oriental guy who does all kinds of extreme things to his Phantom and Mavic Pro drones.
