If there’s one thing a homeowner is likely to shudder at the thought of, when the sub-zero temperatures of winter arrive, it would be ice dams. As a new homeowner, or a family who is new to an area where snow and ice are a seasonal certainty, you may not yet know about the potential dangers of this phenomenon, and why it’s important to reduce the risk of them forming. Here are three ways ice dams can pose a risk, when they develop on your home:
When ice dams develop, the can put a large amount of structural stress on your eaves, which aren’t meant to be filled with solid ice, and/or have ice hanging over their edges. The weight can eventually drive the eavestroughs to separate from the house potentially causing costly damage, not to mention the possibility of hurting someone in the process.
As ice builds up on your roof, the heat coming from your home can melt it , and ice dams can leave it with nowhere to drain. With only one place left to go, this water often ends up leaking into the attic, and possibly even further into your home. This can create all kinds of potential problems, ranging from unsightly water stains on walls and ceilings to damaged electrical work.
Mold and Mildew Growth
Any time there is prolonged dampness in a closed environment, the possibility of mildew or mold developing increases. Whether you have traditional insulation that has become wet, or drywall that is consistently getting wet from water leaking into your home, mold spores are a serious threat to your family’s health.
How to Reduce the Risk of Ice Dams Forming
The most effective way to reduce the risk of ice dams forming is to replace your home’s traditional insulation with spray foam insulation, such as Icynene. Icynene spray foam insulation creates an effective air barrier wherever it is applied, helping to limit the conditioned air that’s inside your home from escaping. This is because Icynene insulation expands to 100 times its original size, helping to fill the tiny cracks and hard-to-reach areas that traditional insulation can’t reach. In addition to this, making sure your attic is vented, or insulating your attic with spray foam insulation like Icynene, can help to keep the warm and cold air on the right side of your roof.
