ABSTRACT:
Disclosed is a shingle having an enhanced relief effect which thereby simulates roofing slate or roofing tile. The enhanced relief effect is provided by covering at least a portion of the underside of the shingle with a layer of expanded particulated material such as spheres of expanded polystyrene. The shingle further includes a stiffening layer over the layer of expanded particulated material which tends to reduce the elasticity of the shingle.
