Zusammenfassung:Roofing granules comprising agglomerated inorganic material, and building materials, such as shingles, that include such roofing granules. By fabricating roofing granules from agglomerating inorganic material it is possible to tailor the particle size distribution so as to provide optimal shingle surface coverage, thus reducing shingle weight and usage of raw materials. Additionally, the use of agglomeration permits the utilization of by-products from conventional granule production processes.
