Rake the snow off the roof edges using a plastic roof rake, going back a few feet. Rake the snow down to the ground. The roof rake has a long handle that allows you to rake the roof snow from the ground.
Adjust the roof rake handle so that it is shorter than needed to reach the roof but long enough to reach the gutters.
Stand away from the house so you are not directly underneath the gutters. Hold the roof rake handle and tap the icicles along the gutters with the rake, breaking off the icicles.
