A method of applying a laminate composition containing a whitening pigment during manufacture of modified bitumen roll roofing membranes, is provided. The laminate composition is heat activated providing greater adherence to surfaces that it applied to, and greater reflective properties. The laminate has an initial energy efficiency rating greater than or equal to 0.65 for a low-sloped roof, or an initial energy efficiency greater than or equal to 0.25 for a steep-sloped roof. |
