Will this product reduce the ice dams on my roof during the winter?

A radiant barrier will usually reduce the possibility of ice damming. Ice damming is caused when the top of the roof warms above the freezing point and the lower part of the roof is below freezing. To prevent ice damming, you want a COLD roof. The roof gets warm due to warm air leakage into the attic from the house AND from the home emitting radiant heat.

 

A radiant barrier installed in the attic will help keep the radiant heat emitting from the home from hitting the roof. The result is a cooler roof deck, which will reduce ice damming. Many customers have seen a significant reduction in ice damming after installing AtticFoil™ radiant barrier. We also also suggest checking to make sure you have good attic ventilation, since cold air entering the attic will also help keep the roof cold.
