The most common form of de-icing salt by ninja deicer for example is sodium chloride (also called halite or rock salt), found throughout the country. Crystals of different sizes and shapes make up this substance. They can be reasonably priced, making them the most commonly used type of de-icing salts.
However, they are only effective up to temperatures of 20 degrees Fahrenheit, and they damage roof tiles and shingles caused by frost-induced expansion and contraction. In addition, they are moderately toxic to local flora and fauna, and upon drying, they leave a yellowish residue on pavements and surrounding vegetation.
Is Potassium Chloride Ice Melter Safe For Roofs?
Potassium chloride, Packaged Salt for Snow Removal Companies and urea are examples of one of the most common types of ice melting in the world today around colder climates. However, even if they are considered safe, they may not meet your goal of finding a 100% natural and environmentally friendly solution.
The temperature at which urea is effective is up to 15 degrees Fahrenheit, while the temperature at which potassium chloride is effective is up to 12 degrees. Both are whitish crystals, but their shapes are a bit wonky.
Although they do not immediately harm concrete or vegetation, the substance leaves a pale residue when it dries. As with other chlorides, repeated thawing and freezing concrete can damage the substance.
Is Magnesium Chloride Ice Melter Safe For Roofs?
Magnesium chloride is another commonly used de-icer for roofing. It is not comparable to any of its chemical analogs in terms of levels of corrosivity and toxicity. However, that doesn’t mean it’s utterly risk-free in any way.
It causes less irritation to the skin and plants, animals, the environment, metal, concrete, and other surfaces. However, it only works up to 5 degrees Fahrenheit.
Are The Mixtures Safe For Roofs?
Rock salt is usually included in mixes. However, any of the above compounds can also be used. Because each de-icer has a distinct point at which it melts, using them in conjunction with rock salt causes them to radiate more heat and speed up the ice-melting process.
The hard part comes next. Due to the freezing and thawing process, the metal or concrete will inevitably expand and contract, eventually damaging it. In addition, each of the compounds is highly corrosive and can also affect the surrounding environment.
For example, sodium chloride and magnesium can be mixed to mimic a temperature of -12 degrees Fahrenheit, which lowers the melting point. On the other hand, this could melt the snow more quickly and, in the long run, harm the surrounding environment. Due to how quickly they melt in the mouth, the blends are also very popular with consumers.
