Hiya, and welcome to BYC!!
We get about the same amount of snow here and opted for an Amish-built shed. We'd do what @DobieLover suggested above, which would be similar.
We have a steel roof that's pitched pretty good but still snow accumulates and hubby pulls it off with a broad metal rake. We also put our old gutters from the house on it that help with the run-off.
I love what you have though!!
