home and garden indoor environmental qualityWhat can you put on your roof to melt ice?
Using Calcium Chloride
An ice dam can easily be made of hundreds of gallons of water, so melting it all requires a lot of salt. Instead, fill old pantyhose with the calcium chloride and lay it across the dam. This will melt a channel to allow water to safely run off your roof and break up the dam for manual removal.
Simply so, what ice melt is safe for roofs?
Most common high performance ice melters such as magnesium chloride or calcium chloride will certainly melt the ice, but they may also cause staining of the shingles and could also cause corrosion of the gutters, aluminum siding, or fasteners.
Also know, how do you melt ice off your roof?
By pouring calcium chloride into this tube-like form, you can position it vertically over the dam—with the sock's end hanging an inch or two over the roof edge—and melt a tube-like channel through the ice dam, which will allow additional water that melts to run safely off the roof.
Use Roof Melt tablets to reduce snow and ice buildup that occurs on your roof, typically on the eaves and in gutters. The tablets are specially formulated with calcium chloride so they won't harm your exterior like products such as rock salt, which could rust your gutters and damage shingles.
