Abstract
A system, including a roofing membrane installed above the roofing substrate, where the roofing membrane includes a polysiloxane layer, where the polysiloxane layer is an uppermost surface of the roofing membrane installed above the roofing substrate, a second layer, where the second layer includes a metal, and a reinforcement layer, where the second layer is between the polysiloxane layer and the reinforcement layer, where the second layer has at least one of the following: a thickness, a type of metal, a percentage of area of the polysiloxane layer covered by the second layer, or any combination thereof, sufficient to reduce by at least 65% a static charge on the polysiloxane layer when compared to a control roofing membrane without the second layer.
