What Are Ice Dams and Why Should a Homeowner Be Concerned If Ice Dams Develop?

Share This Post

Winter is fast-coming, and with it comes the potential for ice dams to form on the edges of your roof. While they may seem harmless, ice dams can cause serious damage to your home and put you at risk of costly repairs. That is why as a homeowner, you should always be on the lookout for ice dams and take necessary actions for your home’s safety.

What Are Ice Dams?

An ice dam is a buildup of ice on the edge of your roof, typically caused by melting snow that re-freezes as it flows down the roof. As the ice accumulates, it can block the flow of water, causing it to back up under the shingles and into your home. This can lead to leaks, water damage, and even structural damage. Ice dams are common winter problems.

How Do Ice Dams Form?

Ice dams form when there is a difference in temperature between the upper and lower portions of a roof. This difference can be caused by a variety of factors, including poor insulation, ventilation, and lack of maintenance.

Heat loss from the living space can lead to warming of the roofing surface, which causes snow to melt, typically near the peak of the roof. As the melted snow runs down to the colder eaves, it refreezes, creating the ice dam. The dam can grow as more snow melts and refreezes, resulting in a large ridge of ice along the eaves.

Why Should a Homeowner Be Concerned?

Ice dams are a significant concern for homeowners for several reasons. First and foremost, they can cause extensive damage to your home. Water that leaks into your home can damage walls, ceilings, insulation, and electrical systems. In extreme cases, ice dams can even cause structural damage to your home.

Ice dams can also put you at risk of costly repairs. If water damage is not addressed promptly, it can lead to mold growth and other serious problems. Even if the damage is repaired, the cost can be substantial. Plus, if you have a warranty on your home, damage caused by ice dams may not be covered.

Another reason ice dams are a concern for homeowners is that they can be difficult to prevent. Once an ice dam forms, it can be difficult to remove it without causing additional damage to your home. And once the damage is done, it can be expensive to repair.

How to Prevent Ice Dams

Fortunately, there are steps you can take to prevent ice dams from forming on your roof. The key is to keep the roof cold, so that snow melts gradually, and the water can flow off the roof instead of freezing at the edge. Here are a few things you can do to prevent ice dams:

Insulate Your Attic

Insulating your attic will help keep the temperature in your attic consistent and prevent heat from escaping into the attic. 

Ventilate Your Attic

Properly venting your attic allows the heat to escape, which will help keep the roof cold. Ensure your house has enough ventilation to allow fresh air to flow in and out freely.

Seal Air Leaks

Seal any air leaks between your living space and attic, this will prevent warm air from rising into the attic and melting snow on the roof.

Keep Gutters Clear

Make sure your gutters are clear of debris. Clogged gutters can prevent water from flowing off the roof, which can cause ice dams to form.

Regularly Remove Snow on the Roof

By regularly removing snow, you can prevent it from building up and causing ice dams.

It is important to note that if you already have an ice dam, it’s best to leave it alone and call a professional. Attempting to remove it yourself can cause more damage, and even can be dangerous.

Potential Damage

When an ice dam forms, the water that is unable to flow off the roof can seep under shingles and into the attic or the walls of the home. This can lead to a number of problems, such as:

  • Water stains on ceilings and walls
  • Mold and mildew growth
  • Rotting of framing, insulation, and other structural elements
  • Damage to electrical wiring and other components in the attic or walls

Bottom Line

Ice dams are a serious concern for homeowners, as they can cause extensive damage and put you at risk of costly repairs. But by taking steps to prevent them, you can protect your home from winter’s worst enemy. 

By insulating your attic, ventilating your attic, sealing air leaks, keeping your gutters clear, and regularly removing snow from the roof, you can help prevent ice dams from forming. Remember, if you suspect you have an ice dam, it’s best to call a professional from Pinnacle Roofing for help rather than trying to remove it yourself.
