Raychem Roof Ice Melt(RIM) Systems are the original, concealed roof de-icing solution since 1993. The RIM systems mechanically protect the self-regulating cable, provide high power output along the entire roof edge and result in an aesthetically pleasing and safe roof de-icing solution. RIM Systems are the world leading solution in successfully preventing ice dam and icicle formations in various commercial and residential facilities. RIM Systems specifically target the ice dam and icicle prone areas of a roof regardless of the roof design, complexities, or snow load.
The success of eliminating ice dam and icicle
problems has led architects and contractors to specify the
RIM system for their projects. In addition, thousands of property
owners have retrofitted their roofs with the RIM system. Over
1,000,000 feet (190+ miles) of roof eaves and valleys, throughout
the world, 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 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. Click here to learn more about roof designs for snow and ice.
THE ICE DAM/ICICLE FORMATION PROCESS
Winter storms build up snow on the roof.
Heat from the building (through insulation, chimneys, and
roof vents) and from the sun (solar gain) causes roof
Melted snow runs down roof lines to valleys and eaves.
melted snow refreezes at the base of the valleys and
at the roof eaves.
As day/night time temperatures cycle up and down, the ice
dams and icicles continue to grow.
Icicles cause 'people and property safety' concerns.
