Abstract
At least some embodiments of the present disclosure provide a roofing accessory that includes a radiofrequency radiation shielding non-woven fiber composite material. The radiofrequency shielding non-woven fiber composite material includes a first fiber type that includes a conductive material, where the radiofrequency shielding non-woven fiber composite material has a sufficient amount of the first fiber type so as to result, when the radiofrequency shielding non-woven fiber composite material is positioned on a roof structure, in the radiofrequency shielding non-woven fiber composite material allowing for shielding a predetermined percentage of electromagnetic radiation passing through the roof structure. The radiofrequency shielding non-woven fiber composite material includes a second fiber type that includes a non-conductive material. The first fiber type and the second fiber type are randomly dispersed within the radiofrequency shielding non-woven fiber composite.
