Ice dams on the roof can be avoided by cleaning the gutters, ensuring proper insulation, adding soffit vents, raking your roof, and installing heated cables. If you need to solve an existing ice dam, use a de-icer or a snow rake, hose water, use warm water, break dams, and hire a pro.
It is never too early to worry and prevent the headaches of the cold seasons. In this guide, you will learn exactly what an ice dam is, how to avoid it from happening, and how to get rid of it once it has formed. Start reading and discover all about ice dams on the roof!
What Is An Ice Dam On A Roof?
An ice dam is an ice ridge that forms at the edge of a roof, which stops melting snow from draining off the roof. As the snow melts due to heat escaping from the home, the water flows down the roof but gets trapped behind the ice dam; that is why roof snow removal is essential.
The trapped water can seep under the roof shingles, leading to leaks, water damage, and other problems inside the home. Ice dams are common in regions with heavy snowfall and fluctuating temperatures. They are often caused by poor attic insulation or ventilation, which allows warm air to escape and melt the snow unevenly.
How To Prevent Ice Dams On Roof?
Preventing ice damming on the roof is the key to avoiding the severe problems it can cause. Try to clean the gutters, ensure proper attic insulation, add soffit vents, rake the roof, and install heated cables. Read more about the strategies to avoid ice dams on roofs in the list below.
Clean The Gutters
Start by keeping gutters clean, especially before the winter season. Clogged gutters can cause water to back up and freeze, leading to ice dams. Removing leaves, debris, and other blockages ensures that water flows freely off the roof and into the downspouts, reducing the risk of ice formation.
Ensure Proper Attic Insulation
Insulation is vital to preventing ice dams. Make sure your attic is well-insulated to keep warm air from escaping into the roof. Insulation maintains a consistent temperature across the roof, preventing the snow from melting and refreezing at the eaves, a common cause of ice dams.
Add Soffit Vents
Proper ventilation is essential to keeping the roof cold. Install soffit vents to allow cold air to enter the attic in order to push out warm air through ridge or roof vents. This balance of airflow keeps the roof cool, reducing the chances of snow melting unevenly and refreezing at the edges.
Rake Your Roof
After heavy snowfall, get a roof rake to remove snow from the roof edges. This simple step prevents snow from accumulating and melting at the eaves, which can cause ice dams. Be sure to use a rake specifically designed for roofs to avoid damaging shingles.
Install Heated Cables
Heated cables can be installed along the roof's edge to prevent ice dams from forming. These cables heat the area where ice dams are likely to develop, ensuring that any snow that melts can flow off the roof without refreezing.
How To Stop Ice Dams On Roof?
Start getting rid of ice dams on the roof by spreading de-icers, using snow rakes, hosing with water, using warm water, breaking the dams, and hiring a professional roofer. Read the details of each step in the list below and be ice dam-free this year and the next.
Spread De-Icer
If you notice an ice dam forming, one effective solution is to apply a chemical de-icer. These products, typically made of calcium chloride, can be spread directly on the ice to melt it. It helps to create channels in the ice dam, allowing water to flow off the roof.
Use Snow Rake
To prevent or reduce the formation of ice dams, remove snow from the roof's edge using a snow rake. With a long handle, this tool allows you to safely pull snow off the roof while standing on the ground.
Hose With Tap Water
If the weather is warm enough, you can use a hose with tap water to break up an ice dam. The water should be applied carefully, aiming to melt channels through the ice to allow trapped water to drain off the roof.
Use Warm Water
Similar to using a hose, applying warm water directly to the ice dam can help melt it. This method is handy if you need an immediate solution. Pour warm (not boiling) water over the ice dam to create channels for the water to escape.
Break Dams
In some cases, physically breaking the ice dam may be necessary. Use a blunt tool, such as a mallet or a wooden implement, to carefully chip away at the ice. Be cautious with this method to avoid damaging the shingles or other parts of the roof. Breaking the ice allows trapped water to flow off the roof, alleviating the pressure on the structure.
Hire A Pro
If ice dams are severe or you are unsure how to handle them safely, it is best to hire a professional. Roofing experts can safely remove ice dams using specialized tools and techniques, minimizing the risk of damage to your roof.
