I think I remember somewhere that said the factory roof rails were rated 165#. I built my own rack and am guessing I've had 425#+ up there (spare tire, sea kayak, h2o, gas, gear, myself, etc) - no indication whatsoever it can't handle it - and I was jumping up and down trying to get it to break, bend, etc (hey, break it while it's under warranty!).

I would say it's more design of the racks than roof carrying capacity - the rails on the H3 are well designed and seem to be pretty much indestructable.
