What is the minimum roof pitch I should use to ensure that heavy (150 psi), wet snow slides off a simple gable roof without shovelling?

This is really very unpredictable and there are so many variabilities such as weather conditions, attic insulation, shading on the roof, etc. Probably a 12:12 or higher pitch would best accomplish what you wnat though.
