Sleet and freezing rain melt once they are exposed to the heat from the attic. That melted water runs into gutters and downspouts where it refreezes when the temperature drops again. The result is ice dams, which block the flow of water from melted snow. Water left on the roof leads to damaging leaks inside the home. Consulting a professional can help homeowners find the proper way to deal with freezing rain and sleet on their rooftop.
