I ran across this today and I’m scratching my head. It was terribly hot and humid and the attic was miserable. I didn’t stay up there for long but I put my hand between the roof decking and the ridge vent and there was no gap at all. On the roof side, there is corrugated plastic material under the ridge shingles but I don’t see how the air can exit the attic without any gaps.
Now there were gaps present between the siding and soffit leaving the OSB sheathing exposed to the elements.
What is it that I’m missing? The home was built in 2001.
