Ice Dam Forms Where You Stopped Raking?

I noticed something odd, and perhaps it's to be expected, but it seems like where I stopped raking, that's where an ice dam formed over the next week or so. When I first raked about 4', an ice dam was there. Then I went another 10' up, and I see another ice dam. Anyone else experience this? Maybe I should have just not raked at all. I bought some scaffolding and have it setup now. I've been up there with chisels and garden hoses trying to get the ice off. In some places it's so thick, probably 8". I hate it.

Yup, it will do that. The answer is, you have to remove it all. If you just leave it, it will be raining inside. There are specific temperatures and snow depths when the snow will insulate the roof, combined with too much heat from below and the bottom layer of snow will melt and feed those darn dams. Once the melt exits the snow layer, it hits that 20 air and ug! you have ice. And as you know, that process just keeps on building upt the ice until there is a pond behind the frozen front.

Getting a thick dam off can be difficult when it is frozen to the shingles. If mother nature will cooperate with some warm sun, the ice will release from the shingles and some tapping on the ice will break it lose, but be careful. I have had the whole roof edge decide to come down at once. There are other tricks, but mother nature is the best. But you need to get ALL of the snow off, front and back.
