Snow sitting on your roof provides insulation value and is not going to avalanche on your kids or vehicle in the driveway.
Metal is fine on a steep pitch roof where the snow slides frequently into a predefined space i.e. not your walkway. On a low angle metal roof the snow collects and slides only during large avalanche cycles. These large slides can damage property or seriously hurt somebody.
Metal and shingles cost about the same. The correct choice depends on your roof angle, roof strength, path of potential slides, insulation, and ventilation.
A good material choice as well as other factors is something that a building contractor can help you with. Define what your requirements are and then work with the roofer(s) that the contractor recommends. This policy should keep you safe from using a roofer that is inferior or does not honour their work.
