Product Usage Instructions:
Installation Process:
1. Measure and cut the polymer heating element according to the
roof’s dimensions.
2. Securely attach the heating element under the shingles using
nails or fasteners.
3. Connect the heating element to the step-down transformer.
Activating the System:
1. Ensure the aerial-mount snow switch or temperature sensor is
properly installed.
2. The activation device will automatically trigger the system
based on weather conditions.
Maintenance:
Regularly inspect the system for any damages or obstructions
that may affect its performance.
Keep the system clean and free from debris to ensure optimal
functionality.
FAQ:
Q: Can the heating element be cut on-site?
A: Yes, the thin polymer heating element can be cut on-site to
fit the specific dimensions of the roof.
Q: How does the system save energy costs?
A: The PTC nano-technology allows the elements to heat
efficiently in cold environments, reducing power consumption and
potentially lowering de-icing costs by 30 to 60% compared to
traditional systems.

Roof De-icing
Low-Voltage Roof De-icing System
Warmzone’s innovative low-voltage roof de-icing systems feature a unique,
self-regulating, semiconductive polymer heating element that is very thin and
can be cut on site and discreetly nailed or stapled under shingles for quick,
easy installation. The advanced heating element is polypropylene fused during
fabrication to achieve water proofing.

Low-voltage Roof De-icing System
Automated Roof De-icing System
How it Works
Warmzone’s roof de-icing systems involve three main components: the polymer
heating element, a step-down transformer, and an activation device (i.e., an
aerial-mount snow switch and/or temperature sensor) that automatically
triggers the system when weather conditions warrant.
The transformer is responsible for a specific section of the de-icing system,
and can step down from high voltage to low voltage (60 V or less). It is the
source for monitoring the power and output to the system’s heating element to
ensure safe, accurate performance of the roof de-icing system.
The activation device/snow sensor (typically mounted at the roof’s edge)
signals the control panel when weather conditions warrant. The sensor detects
moisture and temperature, so when snow begins to fall and the temperature is
below the set point (usually 39°F), the sensor signals the controller, which
then sends power to the heating element to warm the roof.
Features and Benefits
· Extremely Thin Profile The flexible heating element is just 3/64-inch,
allowing for simple, discreet installation under roofing.
· Self Regulating When the ambient temperature rises, the electrical
resistance increases and the consumption of electricity decreases, preventing
the element from overheating and ensuring energyefficient operation.
· Maintenance Free – The system has no moving parts and is maintenance free.
· Easy Installation Roll out the flexible heating element and cut to size
while on the job site for a perfect fit.
Unlike many other roof heating systems, the lowvoltage polymer heating element
can be nailed or stapled through, simplifying the installation process.
· Versatile – Warmzone’s low-voltage system can be safely installed under most
roofing materials, including metal.
· Power Options – The system operates on 24 volts (AC/DC) and can also be
connected to a wind or solar power supply.
· Protective Polypropylene Fabrication The product is polypropylene fused
during fabrication to achieve water proofing.
· Energy Efficient – The roof heating system requires minimal power
consumption. For even greater energy savings when heating metal roofs, use a
heat retention mat.

RoofHeat STEP Roof De-icing System Specs
Roof De-icing
The thin RoofHeat STEP polymer heating element comes in widths of 3, 9 and
12-inches and can be nailed or attached with fasteners or screws under a a
variety of roofing materials, including shingles and metal.
The fully automated maintenance-free roof de-icing system is one of the most
advanced and efficient roof de-icing systems available. The PTC nano-
technology allows the elements to heat with maximum power in cold environments
and use less electricity as they warm up. This minimizes power consumption and
can reduce roof de-icing costs by 30 to 60 percent compared to conventional
cable systems.
