To prevent ice dams on your roof you can install some ice dam prevention heat tape to the edge of the roof.

You can buy the heat tape online.

You should also close up any attic bypasses and seal off air leaks into the attic. make sure you have the proper insulation in the attic and add some roof and soffit vents if you don't have any already.

You can also use a roof rake that is made to remove snow from your roof which will prevent ice dams from forming on your roof.

Metal roofing should be practical, durable, beautifully executed and, of course, safe. In order to fulfill the last requirement, suitable snow holders should be arranged on the roof, which are special structures responsible for the safe descent of snow. They are also necessary to avoid deformation of the roof under a mass of icy snow.
The weight of snow masses can be much greater than the weight of the roof itself, so the loads from precipitation are a serious problem that should be solved even when making foundation calculations.
