My friend and I have a cargo load that fits on the top of the roof, but it's about 500lb. There are roof racks, but we would be putting the cargo between the two racks (not on top of them). We would be placing it on the plastic supports going right over the metal of the roof--the bars that, when pushed down on, touch the roof. Not sure how else to explain it.
We'd be driving on the highway with this cargo for about four hours. We know the danger of rollovers, with so much weight on the top of the vehicle. I'm more afraid of the cargo being so heavy that if we went over a bump the windows might crack or something.
What are the dangers of putting this much weight on the top of a car of this size and build, or would the car be able to handle it no problem?

it's pretty hefty.
Also, essentially, this load will be resting across these plastic bars and on the frame of the car itself. It's about as wide as the car. So I guess a better question might be how much weight the frame of the car could support if we put something on top of it?
We know the max payload capacity is about 800lb.
