GENERAL INFORMATION
PURPOSE OF THIS PRODUCT
This de-icing cable is designed to prevent ice buildups, known as ice dams, from forming
on roofs and in gutters and downspouts. When properly installed and operated, this
product creates a path for melted snow or ice (melt water) to drain from the roof to the
ground. Do not install this product to remove ice dams that have already formed or clear
the roof of ice and snow.
Do not use this de-icing cable for any other purposes, such as to melt snow on sidewalks
or protect pipes from freezing. °STELPRO offers other products designed for these
purposes. See your local dealer or contact °STELPRO.
Improved ventilation (cooling) of the space underneath the roof surface, if possible, can
also reduce the likelihood of ice dam formation. To avoid ice dams, the entire roof surface
should be kept at the same temperature as the outside air. Consult a professional roofer
for expert advice on roof venting. Refer to the
Appendix on page 25
.
WHO SHOULD INSTALL THE CABLE
Although the installation of the cable does not require special skills, you may wish to hire
a professional for a variety of reasons. For example, if you are uncertain about any of the
Electrical requirements on page 6
,
or if you are not comfortable working on a ladder or
roof, consider hiring a professional, such as a licensed electrician.

WHEN TO INSTALL THE CABLE
The de-icing cable should be installed when:
1. There is no ice or snow on the roof.
Do not use this cable to melt snow and ice that has already formed on your roof or
in your gutters or downspouts, as you would not be able to attach the cable pro-
perly with the clips. Additionally, this cable was not designed to melt snow; rather, it
simply provides a path for snow or ice that has already melted (melt water) to flow to
the ground.
To solve ice dam problems when snow and ice are on the roof, contact a professional
roofer for expert advice.
To prevent future ice dams, you can install the de-icing cable once the ice and snow
have melted and before the next winter season.
2. The temperature makes it possible to lift the shingle tabs.
In general, the temperature should be between 0°C and 27°C (32°F and 80°F). Below
0°C (32°F), shingles are brittle and may break off when lifted to install the cable
clips. Above 27°C (80°F), shingles may be warm and tear when lifted to install the
cable clips.
