An asphalt-based roofing material includes a substrate coated with an asphalt coating, a protective coating adhered to the upper surface of the asphalt coating, a layer of granules adhered to the protective coating, and a web bonded to the lower region of the asphalt coating. A method of manufacturing a roofing material includes coating a substrate with an asphalt coating, applying a protective coating to the upper surface of the asphalt coating, applying a layer of granules to the protective coating, and applying a web to the lower region of the asphalt coating.

A method of applying blend drop granules to an asphalt coated sheet includes moving an asphalt coated sheet in a machine direction, and depositing blend drops of granules on a blend drop conveyor that is positioned above the asphalt coated sheet. The blend drop conveyor has an upper flight moving in a direction opposite the machine direction and a lower flight moving in the machine direction. The blend drops are moved from the upper flight to the lower flight of the blend drop conveyor while retaining the blend drops in contact with the blend drop conveyor by magnetic force. Finally. The blend drops are released from the blend drop conveyor for contact with the asphalt coated sheet.
