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.

What materials can be used on low slope roof?

Why use a low slope roof?

The Advantages of Low-Slope Roofing Systems

Installing a low-slope or low-pitched roof improves heating and cooling in comparison to a steep-slope roof due to the fact that there is less attic space to fill up with excess air. This extra air decreases the efficiency of heating and cooling systems.
