The present invention involves the recycling of asphalt based roofing materials by comminuting the roofing material and subsequently separating a rock component from an asphalt component of the roofing material. The asphaltic component is separated into a feed stream having a mesh size of less than about 50 mesh while the rock component is separated into a feed stream having rocks in the size of 10 mesh or larger. A portion of the comminuted material may be recycled back for additional comminuting. The separated asphaltic component is placed in contact with the solvent to dissolve the asphalt in the asphaltic component providing a mixture of filler, fiber and dissolved asphalt. The liquid may then be applied to a surface of a wall to form a substantially continuous solidified film on the wall to provide waterproofing and an air barrier.
