What is an Ice Dam?
Simply put, ice dams form on slanted roofs when the snow on the roof melts due to the heat from the attic. The cause of the ice dam could also be due to the warm attic, causing the water to trickle down.
Preventing Ice Dams
Since ice dams are caused by the melting ice, prevention involves keeping the roof cold. You can do this by ensuring proper insulation of the roof and ventilation of the attic. Check whether your attic is properly insulated and if any upgrades are needed to prevent ice dams from forming.
When upgrading the insulation, choose insulation materials with a high R-value to reduce loss of heat by condition. On the other hand, attic ventilation allows heated air to escape in a controlled manner. This helps in keeping the roof colder while reducing incidences of melting snow.
Importance of a Healthy Roof
The most effective way of preventing ice dams is having a healthy roof. This means ensuring that the roof is fully functional, and does not have any leaks or weak spots. If ice dams form on your roof, water builds up and starts to seep under shingles into the house. You can notice this if you see a large icicle or several small icicles hanging from the roof. You may also find ice in your downspouts or gutters, which causes the water to back up behind it and enter into the house.
