A roofing membrane includes a plurality of resins present in an amount of 30 wt. % to 100 wt. % based on a total weight of the roofing membrane. The plurality of resins include a first resin and a second resin. The first resin includes a resin present in an amount of 20 wt. % to 80 wt. % based on a total weight of the plurality of resins in the roofing membrane; that is not moisture curable; and that is cured. The second resin includes a resin present in an amount of 20 wt. % to 80 wt. % based on the total weight of the plurality of resins in the roofing membrane; that is moisture curable; that is uncured; and includes silicon. The roofing membrane is flexible. The roofing membrane, when exposed to moisture, exhibits a tear strength that meets ASTM D6878.
