Icicles are nothing to be proud of. Yes, they look pretty; all winter meets gingerbread storybook. But they are the housing equivalent of going out in public with your slip showing. They demonstrate something is awry. They mean we don’t have enough insulation. Some of our heat is escaping from the main living areas of our home into the attic spaces. That heat is rising up and warming the roof so that the snow melts, drips, refreezes and slowly but surely forms icicles. That melted snow can also build up at the edge of the roof and form ice dams which can damage said roof.
The winter home equivalent of a gal who looks as if she just stepped out of a band box would be a house with a thick, even blanket of snow across the whole roof - no lumpy ice dams, no stalactite-like icicles, no strips or patches of melted snow revealing the slip, er, the shingles beneath.
That said, here are two photos of the icicles on our home. I shall miss them when our insulation is complete, but not their cause.
