How to Get Rid of Ice Dams: A Comprehensive Guide for Homeowners

December 2, 2023
5 Ways to Stop Ice Dams with Attic Insulation (2023)

Ice damming on roof is a common issue that many homeowners face during the winter months. They occur when snow on the roof melts and refreezes at the edges, forming an ice dam on roof. This ice dam roof phenomenon prevents melting snow from properly draining off the roof, leading to potential water damage. Understanding how ice dams form is crucial to prevent such issues.


Ice dams on roof can cause a range of problems for homeowners. The weight of the ice can put excessive strain on the roof, leading to roof damage. As the water from the melting snow backs up behind the dam, it can seep into the roof, causing leaks and water damage to the interior of the house. Additionally, the constant freeze-thaw cycle of the ice dam can cause gutter problems and damage other roofing materials.

The dangers of ice dams and the potential damage they can cause

Ice dam roofs pose significant risks to both the structural integrity of your home and the safety of its occupants. The weight of the ice dam can put undue stress on the roof, leading to sagging or even collapse in extreme cases. This can be especially dangerous if the ice dams roofs form over an area where people frequently walk, such as a porch or entrance. The falling ice and snow from an ice dam can also pose a hazard to people below.


In terms of potential damage, roof ice dam can cause significant water infiltration into your home. The water that backs up behind the dam can seep into the roof, leading to rotting of the underlying structure and damage to insulation. This ice damming roof issue can result in mold growth and reduced energy efficiency. If left unaddressed, the water damage caused by causes of ice dams can lead to costly repairs and restoration work.

Signs that you have an ice dam on your roof

It's important to be able to identify the signs of an ice dam on your roof so that you can take action promptly. Some common signs include:

  1. Icicles: Large icicles hanging from the eaves of your roof are often a clear indication of an ice dam. They form as the melting snow refreezes at the edge of the roof.
  2. Water stains on walls or ceilings: If you notice water stains or discoloration on your walls or ceilings, especially near the edges of your roof, it could be a sign that water is seeping in through the ice dam.
  3. Dripping or water damage: If you experience water dripping or see evidence of water damage in your attic or upper floors, it could be a result of an ice dam allowing water to penetrate your roof.
  4. Icy patches on the roof: If you can see patches of ice on your roof, particularly near the edges or in valleys, it is likely that an ice dam has formed.

If you observe any of these signs, it's crucial to take immediate action to get rid of ice dams and prevent further damage to your home.

How to get rid of ice dams safely and effectively

How to get rid of ice dams safely and effectively

Removing ice dams on roof should be done safely to avoid injury and minimize the risk of causing damage to your roof. Here are some general contractor expert tips on how to remove ice dams, including how to remove ice dam from specific areas and how to remove ice dams from roof without causing further damage:

  1. Avoid excessive force: Never use sharp objects, hammers, or chisels to chip away at the ice dam. This can damage your roof and gutters. Instead, focus on melting the ice.
  2. Use a roof rake: Start by removing the snow from the roof using a roof rake with a long telescoping handle. This will help prevent further snowmelt and reduce the size of the ice dam.
  3. Create channels: Once the snow is cleared, create channels in the ice dam to allow the trapped water to drain off the roof. This can be done by filling pantyhose with calcium chloride ice melt and placing them vertically across the ice dam. This will create channels for the water to flow through.
  4. Apply heat: Using a warm, gentle heat source, such as a heat gun or a hairdryer, carefully melt the ice dam. Be cautious not to use excessive heat or open flame, as this can damage the roof and increase the risk of fire.
  5. Remove debris: As the ice melts, remove any debris or leaves that may be trapped in the ice dam. This will ensure proper drainage and prevent future ice dams from forming.

Remember to prioritize safety when you remove ice dams. If you are uncomfortable or unsure about performing these tasks yourself, it is best to consult a professional roofing contractor.

Preventing ice dams

Preventing ice dams: Tips for winter roof maintenance

Preventing ice dams is the best approach to avoid potential damage to your roof and home. Here are some tips from a general contractor for winter roof maintenance that can help with ice dam prevention and how to prevent ice dams from forming:

  1. Keep your gutters clean: Regularly clean your gutters and downspouts to ensure proper water flow. Clogged gutters can contribute to ice dam formation.
  2. Insulate your attic: Proper attic insulation is key to preventing ice dams. Insulate the attic floor to minimize heat transfer from the living spaces below. This will help keep the roof surface cold and prevent melting snow from forming ice dams.
  3. Ventilate your attic: Ensure adequate ventilation in your attic to maintain a consistent temperature and prevent the buildup of moisture. Proper attic ventilation will help keep the roof surface cold and reduce the likelihood of ice dam formation.
  4. Seal air leaks: Identify and seal any air leaks in your attic, such as gaps around chimneys, vents, or light fixtures. This will help maintain a consistent temperature and reduce the risk of heat loss that can contribute to ice dam formation.
  5. Remove snow: Use a roof rake to remove snow from your roof after each significant snowfall. This will help prevent the accumulation of snow and reduce the likelihood of ice dam formation.

Insulating your attic: A key step in preventing ice dams

Proper attic insulation and roof ventilation are critical steps in preventing ice dams. Insulation and air sealing help to maintain a consistent temperature in your attic, keeping the roof surface cold and preventing the snow from melting and refreezing at the edges. Soffit vents can also play a crucial role in this process. Here are some tips for insulating your attic:

  1. Assess the current insulation: Start by checking the existing insulation in your attic. Ensure that it is in good condition and adequately covers the entire attic floor.
  2. Add insulation if necessary: If your current insulation is insufficient or damaged, consider adding more insulation to achieve the recommended R-value for your climate. Consult a professional for guidance on the appropriate insulation type and thickness.
  3. Seal air leaks: Insulation alone is not enough to prevent ice dams. Identify and seal any air leaks in your attic, such as gaps around vents, chimneys, or light fixtures. Use caulk or expanding foam to seal these leaks effectively.
  4. Insulate attic access points: Pay attention to attic access points, such as doors or hatches. Insulate them properly to prevent heat loss and maintain a consistent temperature in the attic.
  5. Consider professional assistance: If you are unsure about the insulation process or need assistance, it is advisable to consult a professional insulation contractor. They can assess your attic and recommend the best insulation solutions for your home.

Using heat cables to prevent ice dams

Heated cables, also known as heat tapes or roof de-icing cables, can be an effective solution for preventing ice dams. These cables are designed to melt the snow and ice on your roof, allowing proper drainage. Here are some tips for using heated cables effectively:


  1. Install heat cables properly: If you decide to use heat cables, it is crucial to install them correctly. Follow the manufacturer's instructions and ensure that the cables are installed along the roof edges, gutters, and downspouts, where ice dams typically form.
  2. Use a thermostat or timer: Connect the heat cables to a thermostat or timer to regulate their operation. This will ensure that the cables are only activated when necessary, reducing energy consumption and preventing overheating.
  3. Inspect and maintain regularly: Regularly inspect the heat cables to ensure they are functioning correctly. Check for any damage or signs of wear and tear. Replace any damaged cables promptly.
  4. Consult a professional or general contractor: If you are unsure about the installation or operation of heat cables, it is advisable to consult a professional roofing contractor. They can assess your specific needs and provide expert guidance on the most suitable heat cable system for your roof.
