DOUBLE BOARD ROOFS The older of the two, it is just what the name implies, two layers of boards with the joints staggered . . .
Often with some kind of "waterproof" layer, such as tarpaper, between the layers. This usage goes back at least as far as 1880. Dennis is right about the grooving to direct water flow, which was often retained even with a "waterproof" layer.

INSIDE METAL ROOFS The inside metal roof, which consisted of light gauge metal panels fitted between the carlines, and a T&G board covering . . .
As these were thin-gauge steel sheet, they were often applied between two board layers. That was certainly the widespread arrangement by 1900 for "inside" roofs. Otherwise the sheet metal had to be attached to the bottom of the board roof.
