1. A roof shingle comprising:
a polymer blend, the polymer blend comprising ethylene-propylene-diene terpolymer (“EPDM”) and a thermoplastic polymer, the polymer blend comprising an outward-facing surface and a substrate-facing surface, the outward-facing surface comprising a reveal and a conceal, the reveal being visible when the roof shingle is installed and the conceal being covered by an upslope adjacent roof shingle when the roof shingle is installed;
a reinforcement core, the reinforcement core embedded within the polymer blend;
an adhesive sealant, the adhesive sealant applied to the substrate-facing surface for binding the roof shingle to a downslope adjacent roof shingle or a substrate; and
a plurality of polymer blend granules, the plurality of polymer blend granules being located on at least a portion of a surface of the reveal;
wherein:
the polymer blend being injection-molded above and below the reinforcement core; and
the plurality of polymer blend granules being injection-molded to form at least a portion of the surface of the reveal;
wherein the polymer blend comprises a thermoplastic vulcanizate (“TPV”).
