[450] Ice dam busters

[John Foege]

Going to look something like this once I'm finished. You fill panty hoe
legs with calcium chloride flakes, tie off the ends, and place them
perpendicular to the ice dam with the ends hanging over the eave. They melt
troughs through the dam and allow the pooled water behind it to drain.

This is the quick fix. The long term fix is to ensure you have a ridge
vent, soffet vents, good insulation of the attic floors (dual layers in the
NE even), and that you find and squash any sources of heat leakage into the
attic.

Essentially if you can assure the temperature of the air in attic is the
same as the outside ambient air temperature, you will never have ice
damming and the costly repairs of the subsequent water damage they bring!
