Basic aerodynamics is, greatest force would be a flat plate=20
perpendicular to the air flow, and round would be less. Other than that=20
it becomes complicated, with ratio of sides, skin friction, and other=20
factors. On a sloped roof, the windward side is inward pressure, and lee=20
side outward, but edges (eaves and ridge) cause turbulence.
