Ice dams can be a major headache for homeowners during winter months. Over time, snow accumulates on the roof and then melts and refreezes. This process can cause damage to the roof, gutters, and walls and even lead to water damage inside the home. That is why it is essential to take preventative measures to avoid ice dams. Preventing ice dams on your roof is like putting a cozy winter hat on your home.
In 2023, the winter weather is expected to be wetter. The wetness turns into ice with fluctuating temperatures and back into water more frequently than ever.
Here is a list of ice dam prevention products, their purpose, and knowing when you need professional services.

The first line of defense against ice dams is proper roofing materials. Here are some materials that can help prevent ice dams:
Proper Insulation and Ventilation
Good insulation and ventilation in the attic can help regulate the roof’s temperature and prevent the snow from melting in the first place. Inadequate insulation can cause warm air to escape from the house and heat the roof, melting the snow and leading to ice dams. Ventilation is also essential because it helps remove warm, moist air from the attic, reducing the likelihood of melting snow.
Ice and Water Shield Underlayment
An ice and water shield is a membrane installed underneath the shingles on the roof. It creates a watertight barrier that can prevent water from penetrating the roof in the event of an ice dam or other water infiltration.
Our Favorite Underlayment:
We tested Grace Ice & Water Shield HT, a roofing underlayment made for high temperature environments. It impressed us with its performance and durability. It has a rubberized asphalt adhesive that adheres firmly to the roof deck and a polymeric film that resists UV damage. It also has a Ripcord feature that makes it easy to apply in tricky areas. We think this is a great product for anyone who needs a reliable and long-lasting roofing underlayment.
Metal roofing is a good option for preventing ice dams because it is less likely to accumulate snow than other roofing materials. Snow slides off the smooth surface of the metal roof more quickly than it does on a shingled roof.
Gutter and Downspout Products
Gutters and downspouts are other areas where ice dams can form. The following products can help prevent ice dams in these areas:
Heated Gutter Cables
Heated gutter cables are a popular way to prevent ice dams in gutters. They are installed on the roof and gutters and heat up to melt any ice forming. You can turn these on and off, saving energy and money.
Our Favorite Gutter Cables:
We tested the Frost King roof and gutter cables, a product that prevents ice from damaging roofs and gutters. The kit contained everything we needed to install the cables, including spacers, clips, and instructions.
We found the installation process to be straightforward. The cables prevented ice from building up in the gutters and forming ice dams under the shingles. They also helped to melt the snow faster and prevent leaks. We recommend this product to anyone who lives in a cold climate and wants to protect their roof and gutters from ice damage. It’s a smart investment that can save you a lot of trouble and money in the long run.
Gutter guards are screens or other types of coverings installed over gutters. They prevent leaves and debris from getting into the gutters, which can lead to clogs and ice dams. Also, some gutter guards help melt ice and snow.
Our Favorite Gutter Guards:
We recommend Raptor Gutter Guard for its durability, efficiency and eco-friendliness. It is made from aluminum and stainless steel that resist rust and damage. It fits any gutter and roof type and is easy to install. It filters out debris and contaminants from rainwater using V-Bend, trough and extrusion technologies. It is ideal for rainwater harvesting and self-cleaning. It comes with a 25-year warranty and a 100% satisfaction guarantee. Raptor Gutter Guard is a quality product that protects your home and your water.
Downspout extensions are an easy and inexpensive way to prevent ice dams. They extend the downspouts’ length so that the gutter directs the water away from the house. The downspout prevents water from pooling and freezing at the house’s base, which can cause ice dams.
As mentioned earlier, proper insulation and ventilation in the attic can prevent ice dams. Here are some other attic products that can help prevent ice dams:
Attic insulation can help regulate the roof’s temperature and prevent the snow from melting. It is essential to have enough insulation in the attic to prevent warm air from escaping from the house and heating the roof.
Attic ventilation is essential because it helps remove warm, moist air from the attic, reducing the likelihood of melting snow. It can also prevent condensation from forming in the attic, which can cause mold and other moisture problems.
Attic Door Cover
An attic door cover is a simple product that can prevent heat loss and keep warm air in the house. A cover is installed over the attic door, creating an air seal and preventing warm air from escaping.
In addition to the roofing materials, gutter and downspout products, and attic products discussed earlier, several miscellaneous products can help prevent ice dams.
A roof rake is a long-handled tool to remove snow from the roof. It is handy for preventing ice dams because it allows you to remove snow before it can melt and refreeze. Using a roof rake, you can keep the roof surface clear of snow and prevent the formation of ice dams.
Our Favorite Roof Rake:
We highly recommend the SnowPeeler for efficient and effective snow removal from rooftops. With its sturdy design, the SnowPeeler is ideal for homeowners who prioritize safety, as it allows for snow removal from the ground with stable footing, reducing the risk of accidents. Its unique design and reliable performance set it apart from other rakes in the market.
Calcium Chloride Ice Melt
Calcium chloride ice melt is a chemical product designed to melt ice and snow. You or someone else can spread it on the roof and gutters to melt any ice forming. This product is beneficial for preventing ice dams in areas where heated gutter cables are not practical.
Snow and Ice Melting Systems
Snow and ice melting systems prevent ice dams from melting any snow or ice forming on the roof or gutters. Professionals can install these systems underneath the roofing material or in the gutters and downspouts. They work by heating the surface and melting any snow or ice forming.
If you’re not comfortable tackling ice dam prevention on your own, several professional services can help:
Roof and Gutter Inspections
Roof and gutter inspections are an excellent way to identify potential problem areas before they become full-blown ice dams. A professional inspector can identify areas where insulation, ventilation, or other materials needs replacement to prevent ice dams.
Ice Dam Removal Services
If you already have an ice dam, removing it as soon as possible is essential to prevent further damage. Ice dam removal services use specialized equipment and techniques to remove ice dams from the roof and gutters safely.
Ice dams can cause significant damage to your home if left unchecked. The ultimate list of ice dam prevention products includes various materials and services to help prevent ice dams from forming.
Proper roofing materials, gutter and downspout products, attic products, and miscellaneous products like a roof rake or calcium chloride ice melt can help prevent ice dams from forming.
Suppose you need to be more comfortable tackling ice dam prevention. In that case, professional services like roof and gutter inspections and ice dam removal services can help. It’s essential to take action to prevent ice dams and protect your home from the damage they can cause.
What can I put on the roof to prevent ice dams?
To prevent ice dams on a roof, you can install proper insulation and ventilation in the attic to keep heat from escaping and melting snow on the roof. You can also apply a high-quality ice and water barrier to the roof deck before installing shingles to prevent water from penetrating through the roof. Another choice is to install heating cables on the roof to melt snow and ice before they can form dams. However, this is generally not a preferred option.
How do you prevent ice dams in an old house?
To prevent ice dams in an old house, you can improve insulation and ventilation in the attic to keep heat from escaping and melting snow on the roof. To reduce heat loss, seal air leaks in the attic, including around vents and chimneys. The other option is to install heat tape or a similar system on the roof to melt ice and snow before they can form into dams. However, this is generally not the preferred solution as it can be expensive to run and may cause further damage to the roof.
Does insurance cover ice dams?
Whether insurance covers ice dams depends on your policy and the specific circumstances of the damage. In general, damage caused by an ice dam may be covered by homeowners’ insurance if it results in water damage to the home’s interior. However, coverage may be limited or excluded if the damage results from poor maintenance or neglect. It’s best to check with your insurance provider to understand the specific terms of your policy.
Does spray foam prevent ice dams?
Spray foam insulation can help prevent ice dams by reducing the heat that escapes from the living space into the attic, which can cause snow on the roof to melt and refreeze. However, spray foam alone may not be enough to prevent ice dams. Proper ventilation and air sealing are also important factors. It’s best to consult a professional to assess your home’s insulation and ventilation needs.
Is ice damming the roofer’s fault?
Ice damming is not necessarily the roofer’s fault, as several factors, including poor insulation and ventilation in the attic, air leaks, and weather conditions can cause it. However, suppose the roofer did not correctly install the roofing materials or address any pre-existing issues with the roof. In that case, they may be partially responsible for any resulting ice dams. The specific circumstances would need to be evaluated to figure out liability.
