Snow Load on RTU?
Snow Load on RTU?
(OP)
Should I be adding snow load to the top of a roof top unit? If so, do I add the minimum roof live load (30psf) or the flat roof snow load (~20psf)? My RTU is covering 460 sf of the roof, at 30psf, that's an extra 14 kips I need to account for.
Engineers I know seem to have different views on this, what do you think?

Additionally, if the RTU has any parapets, which I doubt, don't forget to consider drifting of the snow which could locally exceed the 30 psf live load value.
