Ice dam & snow removal in Calgary

“Ice dams” are common under heavy snow loads like Calgary has experienced this year. The city saw a record-breaking snowfall in the first few days of March. Our roofing crews have been very busy as of late with roof ice dam removal and roof top snow removal in Calgary, and various other locations over the last few weeks due to recent storms. This winter has been extreme and difficult for many roofs in Western Canada. Please contact us if you currently experiencing any water infiltrations OR if you simply want to prevent any leaks/damages to your home by removing the snow off the roof.

What is an ice dam?

An ice dam is a ridge of ice that forms at the edge of a roof and prevents melting snow (water) from draining off the roof. The water that backs up behind the dam can leak into a home and cause damage to walls, ceilings, insulation, and other areas. Figure 1 shows a cross section of a home with an ice dam.

What causes ice dams?

There is a complex interaction among the amount of heat loss from a house, snow cover, and outside temperatures that leads to ice dam formation. For ice dams to form there must be snow on the roof, and, at the same time, higher portions of the roof's outside surface must be above 0°C while lower surfaces are below 0°C. For a portion of the roof to be below 0°C, outside temperatures must also be below 0°C. When we say temperatures above or below 0°C, we are talking about average temperature over sustained periods of time.The snow on a roof surface that is above 0°C will melt. As water flows down the roof it reaches the portion of the roof that is below 0°C and freezes. Voila! - an ice dam.The dam grows as it is fed by the melting snow above it, but it will limit itself to the portions of the roof that are on the average below 0°C. So the water above backs up behind the ice dam and remains a liquid. This water finds cracks and openings in the exterior roof covering and flows into the attic space. From the attic it could flow into exterior walls or through the ceiling insulation and stain the ceiling finish.Nonuniform roof surface temperatures lead to ice dams.  

Preventing and dealing with ice dams

In all Calgary communities it is possible to find homes that do not have ice dams. Ice dams can be prevented by controlling the heat loss from the home. 

Immediate action:

  • Remove snow from the roof. This eliminates one of the ingredients necessary for the formation of an ice dam. A "roof rake" and push broom can be used to remove snow, but may damage the roofing materials.
  • In an emergency situation where water is flowing into the house structure, making channels through the ice dam allows the water behind the dam to drain off the roof. Hosing with tap water on a warm day will do this job. Work upward from the lower edge of the dam. The channel will become ineffective within days and is only a temporary solution to ice dam damage.

Long-term action:

  • First, make the ceiling air tight so no warm, moist air can flow from the house into the attic space.
  • After sealing air leakage paths between the house and attic space, consider increasing the ceiling/roof insulation to cut down on heat loss by conduction.
Both of these actions will increase the snow load that your roof has to carry because it will no longer melt. Can your roof carry the additional load? If it is built to current codes, there should not be a structural problem. Roofs, like the rest of the home, should have been designed to withstand expected snow loads. In Minnesota, plans showing design details to meet expected snow loads are usually required to receive a building permit. The plans for your home may be on file at your local building inspection office. To help you understand the plans, or if you cannot find plans for your home, you may want to contact an architectural engineering firm. A professional engineer should be able to evaluate the structure of your home and answer your questions about the strength of your roof.
  • Natural roof ventilation can help maintain uniform roof temperatures, but if the long-term actions described here are done effectively, then only small amounts of roof ventilation are needed to maintain uniform roof surface temperatures. If heat transfer has been reduced substantially, then snow will build up on the roof and cover natural roof ventilation systems, reducing attic ventilation rates. Natural attic ventilation systems are needed to dry the attic space and remove heat buildup during the summer.
