Understanding Ice Dams

Here is an informational video on how the Raychem Roof Ice Melt System efficiently and effectively prevents icicles and ice dams from building up on your roof eaves and valleys.

Raychem Roof Ice Melt Systems have successfully prevented ice dam and icicle formation on roofs across the country for over a decade. Unlike other solutions, such as a cold roof system or zigzag heating cable, Raychem’s RIM Systems are successful preventing ice dams and icicles in heavy snow regions as well as moderate snow regions. Raychem’s RIM Systems specifically target the ice dam and icicle prone areas of a roof regardless of the design, complexities, or snow load. Area Classifications, determine which Raychem Roof Ice Melt products are right for the job by identifying heavy, moderate, and light snow load areas.

The success of eliminating ice dam and icicle problems has led architects and contractors to specify the patented RIM system for their projects. In addition, hundreds of property owners have retrofitted their roofs with the RIM system. Over 480,000 feet (90+ miles) of roof eaves and valleys, throughout the United States and Canada, are protected from ice dams and icicles with Raychem’s Roof Ice Melt System

UNDERSTANDING ROOF ICE PROBLEMS

Ice dams and icicles occur as a result of:

  • Snow buildup on the roof
  • Heat loss from the building
    • Through insulation
    • Through chimneys
    • Through roof vents
  • Winter temperature fluctuations – freeze/thaw cycles
  • Solar heating during winter days with below freezing nights

As roof snow accumulation increases, ice dam and icicle formation likewise increase. Subsequent water ponding can lead to roof leaks, internal building damage and possible mold issues. Falling icicles can create lower roof damage, deck damage and people safety issues.

THE WINTER PROCESS
  1. Winter storms build up snow on the roof.
  2. Heat from the building (through insulation, chimneys, and roof vents) and from the sun (solar gain) causes roof snowmelt.
  3. Melted snow runs down roof lines to valleys and eaves.
  4. The melted snow refreezes at the base of the valleys and at the roof eaves.
  5. As day/night time temperatures cycle up and down, the ice dams and icicles continue to grow.
  6. Icicles cause ‘people and property safety’ concerns.
