Ice dams on the roofs of houses or other buildings can be a huge problem for people living in cold areas. When ice dams occur, water backs up behind them. As it backs up, it can work its way through cracks and under shingles. You can see it running out of soffets or through ceilings and/or walls. Additionally, it flows over the dam, forming icicles. Water can drip onto sidewalk areas and refreeze when it hits the cold surface.
There is a couple of ways to prevent ice dams from forming and causing thousands of dollars in damage. One way is to install electrical heating coils on the roof. This is a very expensive ordeal. We have found an inexpensive and environmentally safe way to prevent ice dams. There is a new product on the market called the Ice Dam Blaster. Pete, the inventor is a chemist by trade.
Ice dams do their damage when there is running water (melted snow) on the roof. This same running water is needed to activate the de-icer to form a brine and work through the ice dam.
How it works: When the de-icers dissolve in the running water, they lower the freezing point of the water. Every de-icer acts differently. The key is to use the correct material to match the intended performance. There are some products out there that can remove and prevent ice dams, however they use harmful chemical ingredients and salts that damage and corrode your roof, and kill the vegetation underneath. Roof de-icers must be non-damaging to the roofing system and the vegetation below (where it runs off). It should not stain the roof and must be easy to put in place. That is EXACTLY what the Ice Dam Blaster does. You should check these out if you have ice dams. They are very inexpensive at around $12, and very effective.
