DUAL APPLICATION OF ROOFING GRANULES TO BITUMINOUS ROOFING MATERIAL
A method of manufacturing a bituminous roofing membrane may include saturating a nonwoven material with a bituminous material to form a bituminous membrane. The method may include applying a first granular material to a top surface of the bituminous membrane. The method may include removing at least some of the first granular material that has not adhered to the bituminous membrane. The method may include heating the bituminous membrane. The method may include applying a second granular material to the bituminous membrane while the bituminous membrane is in a generally planar configuration.
