Proper Ice Dam Removal

Proper ice dam removal is a service which is more of an investment rather than a cost.  An ice dam can be described as a build-up ice on building roofs which may have adverse effects on the building and properties as a result of water leakage through the ceiling. This has been building maintenance problems on sloping roofs especially in cold climate in New Hampshire & MA. Ice dams usually form on sloping roofs when accumulated snows melt and flow down the roof until the melt-water reaches below freezing temperature air. Immediately the melt-water rises to the freezing air, there is an accumulation of ice which forms the dam, and the aftermath snow-melt will not be able to drain properly through the dam. As a result of this, ice may leak through the roofing material which may severe damage but limited to ceilings, roof structure, insulation, walls, and may also cause injury or damage lives and properties when the ice dam falls off or when attempting to remove the ice dams. Going by the saying “necessity is the modern of invention”.

Identification of Ice Dam

Considering the harm posed by an ice dam, it is important to promptly identify and remove it to protect the roof and contents in the building from potential casualty during the winter and snowy seasons. The slope, style and design orientation of a building are critical to forming of an ice dam on the building. Ice dam formations are not limited to the edges of the roof but also develop in other locations. Prompt identification of ice dam is the first step which will help in its removal to save the building and properties from damaging. In achieving this, the weather must be monitored for easy forecasting of ice dam formations. The below steps should also be followed for identification of ice dam;

  • Icicles around the exterior of your house: When icicles are discovered to restrain by the gutters and no water is seen trapped behind them, then the formation of ice dam has taken place. This may cause danger if they fall off. Therefore, it needs to be quickly removed from the exterior of the building.
  • Eaves edge: With experience, it was discovered that 80% of the ice dams form at eaves edges of the building. Therefore, attention must always be drawn these sides for possible ice dam formation.
  • Openings through the roof: Other places for small ice dam formations are any openings such as vents and pipes. So, don’t overlook such areas.
  • Valley areas: Ice dams usually form at Valley areas especially dormers area. However, during ice dam removal, care must be taken not to use chisels or hammers close to valleys as cause damage to the roof.
  • The presence of water stains or moisture: Check along the ceiling of exterior walls of the building for water stains or moisture. The presence of water stains may indicate that an ice dam has formed and possible water penetration.
  • Heated areas: Occasionally, ice dams occur over unheated areas in the house such as porches and garages. Others are furnace and chimney. Occasionally check those areas.
  • Skylight: Ice dam above the skylights are the sneakiest to identify as it is hard to see from the ground. Always look out for ice dam because it often occurs both above and below the skylight.
  • Low pitch roofs: Some roofs have low pitches or angles, such roofs are prone to ice dam formations. Ice dam (say 1 or 2”) can cause severe leakage and damage interior part of the building.
  • Interior rooms: Large ice dams are often found in the interior rooms with arched ceilings. The worst is the bathrooms.
