A method of producing an asphalt roofing composition as well as a novel roofing composition product is disclosed wherein the usual felt base is eliminated. Layers of flowable, viscous asphalt are applied over a moving belt surface and a fiber glass material is introduced between the two layers. In a preferred form, a release agent is placed between the first layer of asphalt applied onto the moving belt surface so as to afford easy removal of the laminated asphalt composition from the belt. The feltless, laminated roofing composition has the advantage of eliminating the use of the usual saturators associated with felt backing type shingles and at the same time affording the reuse of any scrap material.
