A roofing material may include a substrate and a coating on the substrate. The coating may include a polymer blend and at least one filler. The polymer blend may include at least one hydrocarbon oil, at least one resin, at least one polymer, or any combination thereof. The at least one hydrocarbon oil, the at least one resin, the at least one polymer, or any combination thereof may be present in an amount or in amounts sufficient to result in the polymer blend or the coating having a select softening point, a select viscosity, or any combination thereof.

A system includes a roof deck having a slope of 0.25 inch to 3 inches per foot and a roofing membrane is composed of a first material, and at least one photovoltaic module installed on the roof deck. The photovoltaic module includes at least one solar cell, an encapsulant, a frontsheet, and a backsheet. The backsheet includes a head flap located at a first end of the backsheet, and a bottom flap located at a second end of the backsheet. The backsheet is composed of the first material. At least a first portion of the head flap is attached to the roofing membrane, and at least a second portion of the bottom flap is attached to the roofing membrane.

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.
