My south roof is cleaned out after I roof raked. North roof is an ice dam. I raked it and there are open spots but time for the nylons filled with rock salt. I do have ice snow protection layers under the new roof.
I remember that storm. Lots of ice in Westerly RI where I lived. Was supposed to be a foot of snow. Of course a week later I was buried in 18 hours with 22 inches of pure powder with 60 mph winds
