Systems and methods are described herein for manufacturing and using roofing membranes that are faster and easier to install than conventional adhesive-only membrane materials. In some embodiments, membrane materials are surface treated using a plasma flow, e.g., a blown-arc plasma flow, atmospheric plasma, corona plasma, or from portable plasma units, generated by passing a compressed plasma-generating gas through an electrical current to form the plasma-treated roofing membrane. The plasma treatments described herein may be applied as part of the manufacturing process, or in-situ at the site of roof installation. In some embodiments, membrane materials have surface chemistries, roughnesses and other surface characteristics that yield desired adhesion properties.
