I have an educated guess on this thing, but it was raining hard at the inspection and Client was concerned about the wind-driven rain getting in those little louvers there. I explained to him what I thought it was based on the layout of the house and where the downstairs bathroom exhaust fan was venting, which appears to be here. I think the solid piece in the middle protects the vent termination, and the louvers on the side are far enough away so that the exhaust fan can vent. There is a small space between this covering and the concrete shingles underneath so that any rain goes through the louvers, hits the shingles, and simply flows down the roof. The deisgn underneath is such that the vent termination is slightly raised above the shingles themselves so that any wind-driven rain can't get above the lip of the vent termination.
That's my guess.
If anyone has a diagram of the underworkings of this, that would be pretty neat.
