Yup. My house too. More this year than others. I was worried because I just put the gutters on the house myself (trying to save a few $$$) and thought that perhaps I didn't put enough slope on them. Doesn't seem to be the case though. Snow just melts from the sun or warmer spells and then freezes at night or when the temp drops again. I was considering putting heating elements in the gutters which could be turned on when needed, but if it doesn't happen all the time, I won't bother.
