摘要：
A roofing product has a substrate having a binder layer and roofing granules on a majority of the binder layer, such that an exposed portion of the binder layer does not have the roofing granules. In addition, particles may be located on the exposed portion of the binder layer. The particles are smaller in size than the roofing granules, and the reflective particles have a solar reflectance of greater than 10%.
