The question is what were the majors of the students on the roof that collapsed. Architecture and Architectural Engineering majors should know better.

BA in basket weaving students
 
40 x 150 = 6000 pounds looks like a 20 x20 garage = 400 sf 600/400= 15

dead load calculated at 15psf, live load, of dancing, jumping students + alcohol factor???

Required design load of the location, probably much less then the 40 psf required in may area of the North east
 
Reskinned garage from the 1940's; no snow load required near the ocean, structure in the prevailing wind zone from the ocean, salt air environment eats nails, 2x4 rafters at 24" oc. = collapse
 
Don't forget what was hanging from the rafters on the inside
