Ice Dams Can Cause More Damage Than You Think!

The SERVPRO of Matteson-Homewood service area has been hit with snow this week.  The question we get is can snow storms be a possible hazard to my home? The answer is yes, it can!

Typically, we don’t get enough snow that hangs around long enough top worry much about this in our area. Folks in the north are a little more concerned about this than we are because of the greater amount of snowfall and generally colder sustained temperatures. But with snow covering roofs in our area and record low temperatures forecasted the conditions are right for a problem commonly referred to as ice damming.

An ice dam forms when ice builds up on the eaves of the roof and any water behind it has nowhere to go and may end up in your home. This happens because heat gathers in your attic and slightly warms the roof above. The eaves however do not warm like the rest of the roof because they do not have the warm air of your attic under them, they have the cold outside air underneath. As the snow melts from the warmer portion of the roof and runs down it can freeze over the eaves forming an ice dam. As thawing continues above the water running down is trapped behind the dam.

Water will always follow the path of least resistance. In this case it can back up under shingles. Once under the shingle it will makes its way down under the roof inside your attic. From there it can settle on the ceiling or make its way down wall cavities. If snow melts makes its way into your home don’t panic. Stay calm and call SERVPRO.
