The present disclosure relates more particularly to roofing granules, such as solar-reflective roofing granules, and to methods for making and using them in roofing products. Provided are, for example, a collection of solar-reflective roofing granules having a solar reflectivity of at least 70%, (e.g., at least 80 wt % or even at least 90 wt %) of the solar-reflective roofing granules of the collection having a major aspect ratio of at least 4 and a minor aspect ratio of at least 3. Also provided is a roofing product that includes a substrate; a bituminous material coated on the substrate, the bituminous material having a top surface; and a collection of solar-reflective roofing granules as described herein disposed on the top surface of the bituminous material, thereby substantially coating the bituminous material in a region thereof.
