Gravel is placed over tar or asphalt roofs to deflect sunlight to keep the tar or asphalt from getting soft.

Gravel is placed onto built up tar roofs to protect the tar surface from the elements such as ultraviolet light, heat from direct sunlight, snow and ice.. It also helps in evaporation of water from the surface. eg: more surface area which in the summer will help in cooling the building.

It is a protection to the roof. It also helps to fire proof the roof. It makes it possible to walk on the roof too. You can imagine what it would be like in the summer without the rock.
