Title: Sock disappointment
Review: I thought I had the solution to ice damming when I put the sock in the roof valley where I normally get ice build up. It was Dec 14 so I figured we would soon have snow in upstate NY and I would be ready. The sock was full with about 20 pounds of calcium chloride pellets. The next morning the sock was empty. It had rained a little, and all the pellets had dissolved and washed away. Maybe it would be better to wait until the ice dam is forming to put the sock out, or maybe just throw some ice melt on to the roof area from the upstairs bathroom window.
Is the review positive or negative?
