Self-regulating heat cable is the optimum solution for heating roof gutters and drainpipes. The heat cable can also be installed along the roof's edge to help eliminate ice dams - the number one reason behind roof damage, and water damage inside homes.

This product should only be installed in accordance with local and national codes, ordinances, trade practices and manufacturer's instructions.

NOTE: In all locations, route and secure cable to avoid possible mechanical damage from equipment such as ladders, shovels, etc.

Self-regulating heat cable is one of the most affordable and recommended roof de-icing solutions available. The heating cable is easily installed in gutters, downspouts, and along roof eaves to help prevent ice dams and dangerous icicles from forming.

Self-regulating heat trace cable is effective and energy efficient. All Warmzone heat trace cable meets strict safety and performance standards. Warmzone’s self-regulating heat cable features a rugged, durable outer construction to cope with harsh winter weather. The self-regulating properties allow the cable’s irradiated conductive core to increase the heat output as the outside temperature falls and decrease the heat output if the temperature rises. This unique construction makes the heat cable durable, safe, and very energy efficient. Self-regulating heat trace cable is also used with other systems, such as Warmzone's roof de-icing panels.

Pre-Installation Notes

How to Install a Self-regulating Roof Heating and Gutter Trace System
Illustrations showing self-regulating roof de-icing installation tips

In-line splices and tee splices should be avoided when possible.


Heating cable in downspouts can be double-traced (ex. 20 feet of heat cable per 10 feet of downspout) and should be extend below the frost line if tied into a drainage system.


Field-assembled end terminations should not be located in an area where they could become immersed in water. End terminations should not be located at the lowest point of downspouts.


The circuit length for a given over-current protection device shall not exceed the maximum length specified by the manufacturer.


For dome drains on roof, trace the roof around the dome drain in a 5-pointed star pattern about 18 inches out from the center of the dome, then enter the drain about 2 feet and come back out of the drain.


For roof drains leading into a heated area, a loop of heating cable is installed to a typical depth of 2 feet. Trace entire overflow drains.


If the outside jacket of the cable becomes compromised in any way, it must be sealed using heat shrink as soon as possible.


Sharp stones, nails and debris can damage the insulation of the heating cable. Ensure that the area where you are installing the cable is clean of debris to ensure optimum effectiveness and avoid any potential harm to the heat cable.

Self-regulating heat cable is also used with Warmzone’s roof heating panel system. The powder-coated aluminum panels feature pre-engineered channels for the heating cable. The heat cable is installed in the channels and heat is efficiently transferred across the panel, resulting in a highly effective roof de-icing system. The panels are installed along the roof edges (available in a variety of sizes) to prevent ice dams and dangerous icicles from forming. The panels are available in a wide variety of colors to complement the aesthetics of your home or business. The panels can be used on shingle or standing seam (metal) roofs.
