If you live in an area with heavy snowfall, you are no stranger to ice dams. An ice dam is a formation of ice that forms along the edge of a roof, which will prevent the melting snow from draining off the roof. Ice dams are a major problem that can cause significant damage to homes and buildings. Preventing an ice dam is a major factor in protecting your home during winter.

Causes of Ice Dams

Ice dams form in a relatively simple process; it happens when snow melts on the roof and stays in the overhang, which then freezes. There are several factors that contribute to ice dams, like nonuniform roof surface temperatures. Furthermore, the temperature outdoors greatly contributes to the ice buildup. 

Effects of Ice Dams

Ice dam damage can be devastating for a home or building, particularly if left untreated for the entire winter season. First of all, after the dam thaws, the water can leak into the home and damage the walls, ceilings, insulation, and other areas of the house. Furthermore, the moisture that enters the home from the ice dam could lead to mold and mildew, both of which are factors in respiratory problems. 

Ice Dam Prevention

There are many steps that you could use to protect your home or building from damage due to ice dams and prevent ice dams from occurring. 

  • Keep Heavy Snow Off Your Roof, which could be done using a snow rake or going through a professional company.
  • Ventilate And Insulate Well – with proper insulation, you can minimize heat loss through the roof, which is one of the leading causes of an ice dam. 
  • Block Air Leaks – This goes along with ventilation; minimizing air leaks will help prevent warm air from escaping. 
  • Seal Ducts – Sealing any leaks in ducts is important to prevent heat loss.
  • Install Heat Cables or A Metal Roof – heat cables are rather expensive, but they could help minimize ice dams. 

Mitigation of Damage

If you have an ice dam formed, there are a few steps you can take to limit the damage. The first step is to get rid of the water source to prevent the damage from getting worse. Once the water source is removed, you may then go on with the ice dam removal. Furthermore, you need to clean the home environment and maintain its air quality. Finally, removing the snow from the roof with a roof rake after an ice dam has formed will prevent the dam from growing bigger.
