1. A roofing material comprising:
(a) a substrate having a top surface and a back surface, the substrate being uncoated and comprising one of a fiberglass mat, a polyester mat, a scrim, or a combination thereof;
(b) a plurality of self-healing particles embedded into the top surface of the uncoated substrate, such that the plurality of self-healing particles directly contact the top surface of the uncoated substrate, wherein each self-healing particle of the plurality of self-healing particles comprises an external shell and a film-forming material within the external shell, such that one or more self-healing particles of the plurality of self-healing particles is configured to rupture upon impact to the substrate, to thereby dispense the film-forming material to help repair any damage to the roofing material; and
(c) a single coating applied onto the top surface of the substrate having the plurality of self-healing particles embedded therein, to provide a coated substrate, wherein the coating comprises one of an asphaltic coating, a non-asphaltic coating, a polymer-modified asphaltic coating, or a combination thereof,
wherein the top surface of the substrate has an average surface coverage amount of the plurality of self-healing particles of between 70% and 100%.
