The only other alternative for me was to attach a piece of plywood to a long 2x 4 and i rake the snow off the last foot or two.
i wouldn't worry about it. the fact you have the heaters up there means its been addressed in the past.
i think the newer codes require a sheet of asphalt impregnated cloth for the first 3 to 4 feet so even if the melting and freezing occurs , the water won't climb up past it to get in.

i only have coils on the front of my house as well. i'm going to use a snow rake and keep the snow off the first 4 feet of the roof this winter. and look into a new roof in the spring. it is more than 1/2 it's life anyway.
