Building a heated storage from a carport with a shed roof at a 15-degree slope. I've designed it so that the air gap under the outer panel communicates both on the ridge side and the eave side. I'm not sure how else to solve the ventilation for the roof's air gap, as I don't want any vents or similar in the ridge because there's no roof overhang and it's a quite exposed direction, with wind speeding over the neighbor's hedge there as well.
So right now, the construction's air gap is a continuous gap from the bottom edge of the outer walls and up into the roof's air gap and over to the other side. Any objections to that? I'm wondering if moisture will warm up and rise into the roof, increasing moisture load in the roof compared to if the outer walls didn't communicate with the roof. At the same time, I believe it will be quite dry behind the panel.
