1. A process for preparing solar reflective roofing granules, the process comprising:
- (a) providing a binder, inert mineral particles, and solar reflective particles;
(b) dispersing the inert mineral particles and the solar reflective particles in the binder to form a mixture;
(c) forming the mixture into uncured granules; and
(d) curing the binder to form cured roofing granules.

Abstract
Solar reflective roofing granules include a binder and inert mineral particles, with solar reflective particles dispersed in the binder. An agglomeration process preferentially disposes the solar reflective particles at a desired depth within or beneath the surface of the granules.
