Is this winters snowfall going to cost you thousands of dollars?
Removing heavy snow from your roof can prevent expensive water damage caused by ice dams. Water from melting snow on your roof can damage your walls roof and ceilings costing you a lot of money as well as being a huge inconvenience to you.
Water leaks from ice and snow are caused by the heat of your home melting the snow on your roof. Water then refreezes and builds at your gutters. Soon you will have an ice dam. This ice dam builds and prevents water from escaping the roof. The water will then take the path of least resistence under shingles or flashing and finally into your home.
Another option for prevention of ice dams is heat cable. This is electrical cable that can be attached to your roof and in your gutter. It can be plugged in when needed and will thaw and melt ice dams away. Ideally you would want to install a product such as this when it was a little warmer (shingles can be real brittle when they are cold). It can’t be installed after the ice dam has already formed either.
If you need to do something to prevent a flood and a little damage to your roof is considered collateral damage then use a roof deicer that is mostly if not all calcium chloride based. In terms of ice melt chemicals calcium chloride does the least amount of harm to your shingles. A good option is to use Roof Melt ice dam melter. It comes in a 14 pound tub with 60 tablets that you can safely throw on the roof from the ground level. Ideally you want to land the pellets a few feet behind the ice dam. Remember ice dams form due to the heat of your home melting the snow on the roof. More than likely spots that form ice dams are forming them due to heat loss occurring through your roof. Make sure that you have proper insulation in the attic of your home and the ice dam issue should go away.
