Roofs in snowy climates should have a slope of at least a 10-degree pitch minimum. A steeper angled roof sheds the snow more quickly. While the angle of the roof helps shed snow, adding too many angles to the roof for a more aesthetic effect could cause structural problems with snow shedding in the wintertime.Jan 6, 2020

Is a 4/12 roof pitch good?
4/12 is quite typical. Anything under 3/12 is a low pitch roof. Anything above 6/12 is a steep roof pitch since it becomes harder to walk on the roof.
Is 3/12 A good roof pitch?
Any roofs up to 3:12 are generally considered “low slope.” In the residential arena, we see lower slope roofs as part of the home's architectural design. ... Then, when you get into roofs of 3:12 or greater pitch, most other metal roofs can be used and that generally is the pitch requirement for asphalt shingles as well.Jul 5, 2017
