How to Prevent an Ice Dam From Developing on Your Roof

One of the most common reasons why homeowners schedule professional roofing services in the winter and early spring months relates to ice dams. An ice dam is a technical term that describes water pooling behind a wall of ice and flowing backward into the space between the shingles. Keep in mind that roofs are designed to have water flowing downward rather than upward. The wall of ice typically develops when the roof has uneven temperatures. Ice on one area of the roof may melt, and that water may run downward until it reaches a cooler area of the roof and re-freezes. Over time, a wall of ice is created, and this creates the damaging pool of water. Because this can result in roof leaks and water damage inside the home, homeowners may be interested to learn how they can reduce their risk from this type of damage.


Improve Insulation in the Home
A smart idea is to contact a roofers Toronto for professional advice regarding your roof. Through roofing services, you may be able to create seals in some areas that are currently allowing outdoor air to seep into the attic. In addition, you can add more insulation to the attic. Insulation can settle, deteriorate or even be eaten by rodents over time, so adding more insulation can be beneficial. This promotes an even temperature throughout the attic, and it influences the temperature of the roof.

Carefully Seal the Attic
There are many areas of an attic that may not be properly sealed. For example, areas around eaves, ridges and even the chimney and external exhaust areas may not be properly sealed. Even when the attic is properly insulated, these gaps or crevices can allow cold air to penetrate into the attic and can cause uneven roof heating. If you can see even a small amount of sunlight in your attic, you are allowing outdoor air into this space.

Trim Your Trees
Another common cause of ice dams relates to trees hanging over the roof. In an ideal situation, sunlight would hit all areas of the roof evenly. Tree branches, however, can block sunlight and cause temperature differential on the roof. Trimming trees away from the roof can be beneficial. In addition, tree branches can also scrape against shingles during a wind storm. Therefore, trimming back trees can benefit your roof in more ways than one.

No homeowner wants to call for roofing services to repair a leak caused by an ice dam. Ice dams can be difficult to identify from the ground level, but they are relatively common. While it may be impossible to prevent all ice dams from developing, following these helpful tips can minimize your risk.
