Not impossible, but based on their studio photos and Insta, it looks like whatever hangs they were doing were very minimal. Handful of softlights, the occasional truss-supported
bounce fabric. Primary roof loads look like they were air handling equipment and snow/rain ice load. Whenever something like this happens, the first question I have is whether the roof drains were clogged or blocked. If they were iced over and rain was falling on top of an existing snow load, that could stack up a lot of weight really quickly. Certainly looks like the weight of whatever studio equipment they typically had in the air was far dwarfed by what you'd get from a snow/ice/slush load.
