Low-Voltage Roof Deicing Systems
ProLine Radiant offers one of the most advanced and efficient roof deicing systems
available. The low-voltage roof deicing system features flexible polymer heating elements
that can be installed discreetly under roof shingles and are polypropylene fused during fabrication for
protection from alkaline and salt damage. The thin polymer heating element can be nailed and
stapled through and cut on site to facilitate quick, easy installation. (However, do not
nail through the bus braids at the sides of the heating element.)
The roof heating elements are also self-regulating, meaning that when the ambient
temperature rises, the electrical resistance increases and the consumption of electricity
decreases. This prevents the element from overheating and ensures energy-efficient operation.
The automated system features an activation device/snow sensor that detects weather
conditions to automatically trigger the control unit when conditions warrant. The sensor
most commonly used for ProLine Radiant roof heating systems is the durable aerial-mount
When the temperature is below a set point (usually 39°F) and precipitation
is present, the snow sensor signals the controller which then sends power to the heating
element, activating the radiant snowmelt system to heat the roof.
The low-voltage system also utilizes transformers that “step down” high voltage to
low voltage (60 V or less) while controlling a specific section of the roof heating system.
A favorite feature of the transformers is that they operate quietly - unlike other types of
low-voltage roof deicing systems. A controller monitors the power and output to the heating
element to ensure safe, accurate, and efficient performance.
Versatile, Efficient and Reliable
The low-voltage roof deicing system is ideal for a variety of roof heating solutions.
The systems can be easily installed to heat entire roofs, roof valleys and roof edges to
eliminate ice dams from forming.
ProLine roof heating systems have proven to be reliable, easy to install and energy efficient.
The thin, flexible heating element is polypropylene fused during fabrication to ensure
that the panel is protected against UV rays and other potential physical damages. This ensures
effective, reliable roof heating to help protect your roof from the costly effects of heavy
snow and ice damage.
