Why would you say that? Seems unlikely to me, if there's no chance of
condensation from moist house air leaking up under the roof.
Because that's how cathedral ceilings are built base on years of
construction experience...
You might say the same about shark repellent in Kansas :-)

And you might say that you're an idiot, giving out advice based on
equations, without knowing anything about the real world, construction,
or how roofs are properly ventilated.
