Not quite what the OP asked but...
My low pitched corrugated asbestos garage roof drips condensation from
the underside in cold damp conditions.
What pitch does the roof need to be to cause the condensation to run down
rather
than drip off?


Now there is a curious question.

With MANY variables, like teh surface tension ofteh water, and teh
stickiniess of the roof interiors, its roughness and so on.

In short, it depends on too many variables to give any answer other than
a really rough one.
