PROBLEM TO BE SOLVED: To provide a device for glazing a roofing tile, which is capable of forming a shade, mottled pattern or other design pattern on a roofing tile. SOLUTION: This device is composed of: four spray guns 1a, 1b, 1c and 1d, each of which has a different nozzle direction from those of the others; a tank 2 containing a glaze; an air source 3 consisting of a compressor for supplying air to each of the spray guns 1a, 1b, 1c and 1d and tank 2; solenoid valves 7a, 7b, 7c and 7d for performing or stopping the supply of air from the air source 3 to the spray guns 1a, 1b, 1c and 1d, respectively; and a controller 8 for controlling the solenoid valves 7a, 7b, 7c and 7d. The method comprises controlling each of the spray guns 1a, 1b, 1c and 1d by using a built-in program within the controller 8, to select optional one or plural spray guns from the spray guns 1a, 1b, 1c and 1d and to spray a roofing tile with the glaze.
