Where is This Water Coming From?

Where is the water coming from? Given when and under what conditions Metzger’s building has shown water leakage, my best assessment is that his well-insulated and air-sealed unvented roof has about R-24 or more on TOP of his roof cladding when it has 2-plus feet of snow up there for an extended period of time. There is enough heat loss trapped by the snow cover to result in melting over the portion of the roof above conditioned space Insulated, air-sealed part of a building that is actively heated and/or cooled for occupant comfort. but then it runs down and hits the 3-foot overhang that is quite cold and an ice dam develops. At a 3.5:12 pitch, the ice dam easily builds up enough water to overwhelm the 1-inch standing seam.
