  • Method of making a thick shingle
    Patent number: 5232530

The shingle incorporates an upper layer (12) of conventional asphaltic composite roofing material and a lower layer (14) of a polymer foam having a thickness between 1/16 inches and one inch. The foam effectively thickens the shingle to give a layered appearance to a roof using the shingle.
