Estimate the Cable Length You Need
An accurate estimate of the cable length you need is important
because you cannot change the cable length by cutting,
splicing or altering it in any way. Doing so may result in fire,
electrocution, or ice dam formation. Cable should be
installed on roof areas where ice dams form. This can be the
entire roof edge or specific areas such as beneath skylights,
in valleys or around dormers. Cable should also be installed
in any nearby gutters, downspouts and/or valleys.
• If you need to apply the cable on a roof with gutter,
downspouts, valleys, and/or dormers,
follow “A. For Typical
Roof Applications” below.
• If you only need to install the cable in the gutters only, follow
“B.
• If you need to install the cable on a roof with special roof
areas such as a roof with skylights, follow “C. For Roofs with
Special R
oof Area Applications”
A. For a Typical Roof Application
Step 1.
For each area listed in Table B-1, measure the
required dimensions (see Figures 4 and 5 and calculate
the length of cable needed. Add each “area” calculation to
determine the total cable length needed.
