Systems and methods of forming roofing shingles having selected patterns of an adhesive material applied thereto include a conveying system along which a roofing substrate material is conveyed past an adhesive applicator having a nozzle configured to apply a fiberized adhesive to a surface of the roofing substrate material, the fiberized adhesive adapted to attach a layer of the roofing substrate material to an additional layer for forming the roofing shingles. A drive system is coupled to the nozzle and is configured to move the nozzle across the roofing substrate material as the roofing substrate material is moved along a processing path for selectively applying a pattern of the fiberized adhesive across the roofing substrate material.
