摘要： A roofing shingle comprising a base mat having a tab portion covered with granules and a headlap portion covered with a mask or film layer. An asphalt-based coating is applied to at least a top surface of the base mat. The film layer is adhered to the asphalt-based coating applied to the headlap portion and the granules are adhered to the asphalt-based coating applied to the tab portion. The film layer is adapted for preventing granules from adhering to the headlap portion of the base mat and, as such, the headlap portion may be substantially free from any granules adhered thereto. A method for manufacturing a roofing shingle is also provided wherein granules that are not adhered to the tab portion of one shingle may be collected and reapplied the tab portion of another shingle.
