1. An article comprising:
a roofing membrane configured to be positioned on a roof structure;
wherein the roofing membrane consists of:
a single layer, wherein the single layer comprises:
a binder;
a first non-woven fiber type dispersed in the binder;
wherein the first non-woven fiber type comprises a conductive material;
wherein the roofing membrane has a sufficient amount of the first non-woven fiber type so as to result, when the roofing membrane is positioned on the roof structure, in the roofing membrane allowing for shielding a predetermined percentage of electromagnetic radiation passing through the roof structure; and
a second non-woven fiber type dispersed in the binder;
wherein the second non-woven fiber type comprises a non-conductive material; and
wherein the second non-woven fiber type is configured to provide structural reinforcement;
wherein the first non-woven fiber type and the second non-woven fiber type are mixed so as to be randomly dispersed within the binder of the single layer.
