The easiest and most common sense approach is to keep the roof as simple as. Besides being able to support the weight of all that snow a roof needs to be designed to avoid ice dams sliding snow excessive icicle formation and drainage onto high traffic areas. Lower slopes don t handle wind driven rain as well.
