Rocks gravel are for ballast weight to hold the roofing material on and to reflect heat and sunlight to prolong the life of the roof.

That s all there is to it. The gravel prevents sun hail errant baseballs etc from damaging the membrane the all important moisture seal created by the tar paper and tar. They hold down the tar roof by their weight they prevent uv damage and erosion of the tar and asphalt paper and limit debris that can stick to it. Some buildings have have rocks on the roof of it.
