We live in Minnesota, We Get Ice Dams
Ice dams not only pose a threat to the structural integrity of your roof but can also lead to water damage inside your home. Fortunately, there are effective strategies that roofing professionals employ to both remove existing ice dams and prevent their recurrence.
A common question we get from homeowners: “is there anything you can do to my roof to help us with ice dams?” The short answer is ice dams are not caused as a direct result from problems with your roof. That’s just where they reside!
Ways to help….
1. Insulation and Ventilation:
Don't overlook the importance of proper insulation and ventilation in preventing ice dams. This is the most important factor to prevent ice dams. A well-insulated attic coupled with adequate ventilation helps maintain a uniform roof temperature, reducing the conditions conducive to ice dam formation.
2. The Power of Hot Water:
One method for swiftly eliminating ice dams is the use of hot water. By gently running hot water over the ice dam, it can be melted, allowing water to drain through the gutters. However, it's crucial to exercise caution to avoid causing damage to the roof or exacerbating the problem.
3. Harnessing Heat Cables:
Heat cables offer a proactive solution to ice dams. Installing these cables on the roof during the warmer months ensures that they are ready to melt ice dams when cold weather arrives. Roofers may recommend using heat cables temporarily or installing them permanently, especially on roof planes that receive little sunlight and are prone to ice dam formation.

4. Strategic Snow Removal:
If warmer weather is in the forecast, removing the remaining snow on the roof can prevent the formation of new ice dams. Professional roofers, equipped with the necessary expertise, should handle snow removal to avoid damage to shingles. It's advisable to leave a thin layer of snow, as suggested by the National Roofing Contractors Association (NRCA), to protect the roof from direct contact with shovels or rakes.
5. Roof Raking:
For a more hands-on approach, using a roof rake to remove snow from the lower portion of the roof, especially near the eaves, can prevent ice dams from forming. This method is a proactive way to manage snow accumulation and mitigate the risk of subsequent ice dams.
Conclusion:
Dealing with ice dams requires a combination of proactive measures and timely interventions. From proactive measures like insulation and ventilation, to remediation methods like hot water applications, heat cables and strategic snow removal, homeowners have several tools at their disposal. However, it's crucial to approach these solutions with care and, when in doubt, seek the expertise of a qualified roofing professional to safeguard both your roof and your home.
