MEASURE

• Horizontal length of each roof section to

be protected, in feet ......................

• Depth of overhang for each roof section,

in inches .................................

1.0 from the multiplier ...................

C. Multiply length of each roof section by

its overhang multiplier ...................

D. Total all the section dormer

measurements ..........................

E. For each downspout with cable running

down and back up, typically all but the
last one on a cable run, multiply length

by 2 and add together ...................

F. Total length of downspouts with cables

running down only, typically the last

one in a cable run........................

G. Multiply the number of valleys by 6 ........

CONTROL YOUR ROOF AND
GUTTER DE-ICING SYSTEM

The Roof Sentry RS2 unit
automatically controls
operation of ADKS
electric roof de-icing

cables. It measures

both temperature and
moisture to turn the
system on or off in
response to changing
weather conditions.

ADKS Series

Electric Roof De-icing Cable

Prevent Roof Damage & Leaking

Keep Gutters & Downspouts Flowing

Pre assembled Ready-To-Install

KEEP GUTTERS AND DOWNSPOUTS FLOWING ALL WINTER LONG

ADKS roof and gutter de-icing cables help end costly ice damage by preventing ice dam formation and promoting the free ow 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 combustible materials. Not suitable for use on metal roofs: contact EasyHeat for appropriate cable solutions.

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 rooine 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 EasyHeat 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 sufcient quantity and

amp rating are required within six (6) foot cord-set

length of the cable/control starting point.

Cable Installation Patterns

One cable may cover both roof and gutter areas, or
separate cables can be used.

MEASURE ROOF OVERHANG

Install cable over unheated portion of roof — normally roof
area above overhang. This helps to ensure that water owing
onto the unheated roof area will be able to ow to the
ground. Installing cable in valleys, gutter and downspouts

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 gure 1)

with corresponding multiplier as follows:

Overhang Multiplier
Roof

Overhang
in (cm)

Less than 12 (30) 4.0 3.0
12 (30) 4.0 3.0
24 (60) 5.3 4.3
36 (90) 6.8 5.8
48 (120) 8.1 7.1
60 (150) 9.6 8.6
72 (180) 11.2 10.2

Note: For overhangs not listed, estimate multiplier. For example, for an
18 in (45.7 cm) overhang with a gutter, multiplier will be about 4.7.

MEASURE LENGTH OF ROOF

Measure horizontal roof length to be covered by cable;

1

multiply by Overhang Multiplier to determine total
cable length for roof area.

Add cable for downspout (A in figure 2). NOTE: if a

2

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).

Add extra cable for valleys (6´ per valley, C in figure 2)

3

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.
