I live in the northeastern US, and the temperatures this month have been around 10 degrees or colder most of the time.
My house is the only one on the street with icicles. I know that means I've got some sort of issues with my roof.
We have a crawlspace attic. In 1996, we had a new roof put on (second layer of shingles on one side; brand new plywood and a single layer of shingles on the other). As part of the roofing, we had a ridge vent put on, and the roofers said that they made sure the soffet vents in the attic were clear. But we get icicles every year, and our house is always the first one to have no snow on its roof.
What's wrong, and what are some simple (and cheap!) ways to remedy this?
