Is magnesium chloride safe for roofs

In cold climes, snow buildup on roofs often leads to ice dams, usually at the gutter. When the snow melts, the dam can route water under roof shingles and cause roof damage. Ice dams are caused by snow buildup, so the best way to prevent them is to clear the snow off your roof after every snowstorm. Which deicer should I use? Safe Step Extreme seems to be one.

Magnesium chloride is a snow and ice salt made up of magnesium and chlorine. In addition, a study of concrete deterioration by deicing salts, including MgCland CaCl at Iowa State University found that “ magnesium chloride was the most destructive salt with severe. CaClis also a common food ingredient and is “Generally Recognized as Safe ” by the US Food and Drug Administration. My problem is that the ice is coming off in huge chunks and it posses a great danger to patrons of our building.

I was wondering if throwing up some rock salt on the building over the weekend would rust . It certainly would not be a good idea to do this on a regular basis. It is not as likely to stain or cause corrosion as sodium chloride , but it can damage wooden gutters. It melts ice faster than sodium chloride does, works at lower temperatures than sodium chloride and also melts larger volumes of ice. It works at lower temperatures than either magnesium or potassium chloride. Calcium chloride or magnesium chloride should not stain a normal asphalt shingle roof , though there may be a white residue which will, over time, rinse off with normal rain or you can hose it down in the spring.

As far as aluminum siding goes, rock salt is much more corrosive to metals than calcium chloride, but then again . As my neighbor apparently knows, you remove snow from the roof because otherwise, the interior ceiling heat melts the bottom layer of snow. Brookmyer, the chief executive of Bare Groun said the product is largely magnesium chloride but also has a corn-based component, which enables it to work .

The gutters clog up with ice, then water runoff from the roof gets trapped by the dam and eventually backs up the roof , travels under the shingles, and leaks into the house. The calcium chloride will eventually melt through the snow and ice and create a channel for water to flow down into the gutters or off the roof.

The success with the Ice Dam Blaster is by placing it parallel to the gutter to have the small flow of roof water come in contact with the safe chemical in the Ice Dam Blaster. Roof Safe Ice Stuff - all these products are 1 safe , will not corrode metal, fasteners or damage concret or vegetation.
