If the icicles have taken root on your home, you might want to take a closer look at them. A few frozen fangs won't hurt but a hefty crop of stalactites might point to a problem.

It hasn't been warm enough to melt the snow off our roofs and that could mean that heat from the home has helped sculpt the icicles. Roof inspectors say that shouldn't be happening and it could be a sign of damage inside the homes.

Dave Nelson's ceiling is showing water marks and he says, "The stain just gradually moved halfway across the kitchen here. My first thought was to call the roofing company and yell at them."

Then he found out that there was nothing wrong with his new roof. He was experiencing problems because the exhaust vents on his roof were plugged up with snow, trapping heat inside his attic space.

Roof Pros owner Pat Muhs says the temperature in the attic is supposed to be the same as the temperature outside.

Muhs says, "All the heat that is inside the attic is coming up from the attic space and is melting all the snow from the inside out. All that water, as it backs up along the eave lines, is backing up inside the roofs and creating icicles and frost and leaks inside the houses."

To solve Nelson's problem, Roof Pro workers are removing all the snow from his roof.

Art Quast has also been having problems but removing the snow from the roof is too dangerous because of the steep incline. He'll have to wait for all the snow to melt.

Quast says, "We just get to keep emptying buckets. That's all we can do."

It's extremely dangerous to climb onto the roof, so don't do that to clear off the snow.

There is such a thing as a roof rake but the tools are sold out at many stores.
