Roof De-icing Cable
ADKS roof and gutter de-icing cables help end costly ice
damage by preventing ice dam formation and promoting
the free flow of water through gutters and downspouts to
ground level.
This product is for the sole intended use of preventing ice
dams from forming on inclined roofs with tab shingles, in
gutters and in downspouts. This roof de-icing cable is not
intended for use as a snow-melting system to clear roof of
ice and snow. Never install on a flat roof. Never install on com-
bustible materials. Not suitable for use on metal roofs: contact
Easy Heat for appropriate cable solutions.
Includes: De-icing Cable, Shingle Clips, Cable Spacers,
Installation Instructions and Electrical Panel Labels.
Measure Length of Roof
1 Measure horizontal roof length to be covered by cable;
multiply by Overhang Multiplier to determine total
cable length for roof area.
2 Add cable for downspout (A in figure 2). NOTE: if
a downspout is located anywhere other than at the
end of the cable routing, that downspout will require
double length of cable (B in figure 2).
3 Add extra cable for valleys (6´ per valley, C in figure 2)
and around dormers (D in figure 2).
Example: 24 feet of roof, 24 inches overhang (therefore
using Overhang Multiplier of 5.3), 2 downspouts at 10´, one
at end of cable run, and one at midrun, 1 valley, 1 dormer
with 30´ perimeter.
Cable length = (24 x 5.3) + 10 + 20 + 6 + 30 = 193.2 feet
In this example, select ADKS-1000 (200´), as it is closest to 193.2
feet. Use excess cable in valley or downspout.
Compare your total to standard lengths available from
your retailer. Specify closest product possible to your total
need. De-icing cable cannot be cut or altered; doing so voids
the warranty. Once cut, it cannot be repaired.
DESIGNING A SYSTEM
• Sun exposure, prevailing weather direction and roof
shape may result in different conditions at different
points on a roof. Several controls and shorter cable runs
may be appropriate. If only one control is used, it should
be located to respond to the worst icing conditions.
• The length of roofline alone does not determine cables/
controls needed. Consider: roof design and size; gutter
and downspout location; number of sides of a typical,
peaked roof to be protected.
• Use of a temperature and moisture sensing control,
such as the Easy Heat RS-2 Roof Sentry, is highly
recommended. Using a proper control will ensure the
system is automatically energized only when needed. Use
one RS-2 for each ADKS cable installed.
• Use a ground fault protection device or outlet.
• Weather-proofed outlets of sufficient quantity and amp
rating are required within six (6) foot cord-set length of
the cable/control starting point.

DETERMINE ROOF DE-ICING CABLE NEED
Measure Roof Overhang
Install cable over unheated portion of roof — normally
roof area above overhang. This helps to ensure that water
flowing onto the unheated roof area will be able to flow to
the ground. Installing cable in valleys, gutter and down-
spouts as well creates an ice-free pathway for water to
drain completely from eaves and gutter. For your de-icing
cable requirements, determine the roof overhang (E in
figure 1) with corresponding multiplier as follows:
* Length of cable required per foot of roof length. Note: Multiplier
shown includes 1 foot of gutter cable for each foot of roof edge.
