Warmzone's low-voltage RoofHeat STEP roof deicing system is an excellent roof heating option for discreet roof heating. Unlike most other roof heating systems, the heating element of this system is not a heat cable. The system features a thin polymer heating element that can be nailed and stapled through, and cut on site.

RoofHeat STEP Roof Heating Systems

The thin, semi-conductive polymer heating element can be discreetly secured under the shingles or roofing surface. The flexible low-voltage heating element can be nailed or stapled through, further making installation quick and easy, and is polypropylene fused during fabrication to achieve water proofing and protection from alkaline or salt damage.


Transformer for roof heating system.Each RoofHeat transformer steps down high voltage to low voltage (60 V or less) while controlling a specific section of the roof deicing system. The individual control boxes are the source for monitoring the power and output to the heating element to ensure safe, accurate, and efficient performance.


An activation device/snow sensor detects precipitation and temperature to automatically trigger the control panel when conditions warrant. After receiving the signal, the controller then sends power to the heating element, activating the radiant snowmelt system and heating your roof.

A Closer Look at Radiant Roof Heating Systems

Electric, radiant roof heating and deicing systems contain three main components:

RoofHeat STEP low-voltage heating element. Heating Element - RoofHeat STEP radiant heat systems are used for melting ice and snow under shingle roofs. Our heating elements vary in width and are very effective for roof deicing. The flat heating element is installed underneath the shingles. Our radiant heat specialists can help determine which roof heating element is best for your application. Images of various roof heating elements can be viewed on the Roof Heating Installation page.


The roof heating system is self-regulating, which means that when the ambient temperature rises, the electrical resistance increases and the consumption of electricity decreases, preventing the element from overheating and ensuring energy-efficient operation.

Power Unit - (pictured above) Each individual power unit controls a specific section of the deicing system. The transformer of this low-voltage system steps down high voltage to low voltage (60 V or less), and monitors the power and output of the heating element under the roof to ensure safe, optimal performance. This system heats your roof evenly to melt snow and ice, protecting your roof from ice damage.

STEP Low-voltage roof deicing system Touch thermostat activation device.

RoofHeat STEP Touch Thermostat - This advanced thermostat is the activation device of choice for the RoofHeat STEP low-voltage roof deicing system. The thermostat is beautifully designed for simple two-control functionality for ease of operation and features a 3-digit, auto-dim LED display. The Touch sensor controls are maintenance free and the unit is perfectly suited to work seamlessly with all Warmzone radiant heat systems. The versatile unit works with snow melting, roof deicing, and floor heating systems, and is capable of interfacing with smart home systems. All settings are stored in permanent memory for instant recovery in the event of a power failure (no batteries are needed). For more information and technical specs, please refer to the Installation and Operation Manual on our website.

Activation Device - While the STEP Touch Thermostat is the recommended activation device for the STEP low-voltage system, the roof heating system can also utilize an aerial-mount activation device. A variety of options exist, to please speak with one of our radiant heat experts to determine the best configuration and controls for your system.
