Ice Damming Issues

Snowguards Needed on RoofIf you live in a cold area, you can understand the affect of a cold climate on roofs when they are subjected to freeze and thaw cycles. According to roofing tips by our resident roofing expert, Tim Gentry, your roofing material must be robust enough to survive heavy loads of ice and snow. And, ideally, it should be equipped with snowguards. This will help keep the risky roof avalanches at bay. In addition, another common issue with roofs in winter is the ice damming problem.

What is ice damming? It happens when snow under the roof area starts melting due to heat loss. This results in running water on the roof which later re-freezes at the roof edge where there is less heat. As a result, this ice dam does not allow water to be drained into the gutters which can lead to roof leakage as the water collects up on the roof. Structures with poor insulation or poorly ventilated areas are more prone to ice dams in cold climates.

In order to prevent your roof from falling victim to ice damming, try to minimize the heat transfer across the roof. This is possible only if the outside atmospheric temperature and the inside attic temperature are the same. Making sure your attic is well insulated can help fulfill this purpose. By using stick and peel membrane on the bottom of the roof, the attic area can be easily made more watertight.
