Is Magnesium Chloride Safe For Roofs

If you re not careful however magnesium chloride.

Is magnesium chloride safe for roofs.

In our experience magnesium chloride is the safest and all around best easy to find ice melt you can use in an absolute emergency. Rock salt is sodium chloride cheap and poor. Although magnesium chloride still has risks associated it in my opinion it s the lesser of all evils. 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.

Calcium chloride is the most aggressive ice melter working down to well below zero and magnesium chloride is very good. Compared to less soluble forms of magnesium magnesium chloride is absorbed almost completely in the gut increasing its bioavailability in the bloodstream. Magnesium salts like magnesium chloride are better able to correct magnesium deficiencies because they can be dissolved in water. It s environmentally friendly and safe around plants if it s not over applied and it works well sub zero temperatures.

Salt will leave a white residue and is very corrosive to unprotected ferrous metals so you might turn your black roof edge into a chalky mess with salt.
