Good plans. And yes, the weight of snow is more evenly distributed on a roof that has a centered ridgeline and a "gabled" look. The pitch of the roof will matter as well and someone at the building place should have the specs of the requirements for the weight of snow higher than that accumulation on the roof, known as snow load. The roof must be rated higher than the snow load.
