Abstract
This paper discusses how granules from various roofing samples were studied for their size grading and densities. Geometric arrangements were analyzed, using specific sizes of spheres that would provide total coverage of a theoretical plane surface. The effect of removing spheres of successively smaller sizes from the theoretical surface was compared with that of removing granules from an actual roofing membrane.
