It doesn't really, but it does keep the colder air from reaching it hence the affect of the melting process. It's okay for thin ice and mostly clear ice, but not if you're trying to break a chunk off your roof. If this is a question for homework, the answer is this: Salt doesn't melt ice. Instead, the properties of salt repel cold air and attract warmer air, seemingly melting the ice. It is efficient for sidewalks and small portions, but not for larger jobs. The ice does melt because the salt makes the freezing rate lower
