摘要： Provided are roofing membranes comprising pressure-sensitive adhesives particularly adapted for use at cold temperature, and methods for using same. In one aspect, the disclosure provides a roofing membrane comprising: a bituminous sheet having a lower bituminous surface and an upper bituminous surface; and a non-bituminous cold-temperature pressure-sensitive adhesive disposed on the lower bituminous surface, the upper bituminous surface, or both, wherein the cold-temperature pressure-sensitive adhesive has an average adhesion of at least 10 lbs/ft (146 N/m) at 2° C. as measured by a two hour T-peel test.
