last winter i shingled a roof with a buddy, ur basic gable two slope roof. I had the easy side, no vents or stacks or chimneys which he had. We had my compressor and 2 coil nail guns. I beat him to the peak but he was only 2 rows behind, and he was using a hammer lol. I asked him why he didnt use the gun and he said he wanted to go old school and handbomb it and get a nice 8 hour workout.
