Salt can be very dangerous for your roof and can cause damage that can be very expensive to repair. Salt and chemicals are designed to melt the ice on your roof when it is sprayed onto it. The problem with this type of product is that it will also melt any snow or ice that may be on your roof at the time, which causes potential water damage if not caught immediately. Not only does this make a mess but it can also cause leaks in your home which are very expensive to repair. So, which ice melt should you use on your roof and where does ice melt faster?
