1. A roofing system comprising:
a roofing membrane,
wherein the roofing membrane has at least one untreated surface, wherein the at least one untreated surface has a surface energy of 40 mN/m or less;
a roofing substrate,
wherein the roofing substrate is selected from the group consisting of at least one of a plywood substrate, an underlayment, a roof deck, or any combination thereof; and
an adhesive,
wherein the adhesive is located between the roofing membrane and the roofing substrate,
wherein the adhesive directly contacts the at least one untreated surface of the roofing membrane and the roofing substrate;
wherein the adhesive adheres the roofing membrane to the roofing substrate;
wherein the adhesive, when applied at a thickness of 27 mils to 33 mils and when located between the roofing membrane and the roofing substrate, exhibits a peel strength of at least 5 lbf./ft., as measured by lifting the roofing membrane from the roofing substrate at 180° and at 77° F.
