Yes, roof heating cables are highly effective in preventing ice dams. They work by warming the roof and gutters, preventing the buildup of ice and snow. Our Roof De-icing Cable Controller helps ensure the system operates only when needed, maintaining roof safety and performance during winter.

The cost of running roof heating cables depends on the cable length, wattage, and electricity rates. For example, a 50-foot roof heating cable with 7 watts per foot and running 12 hours a day:

Northern United States Example
  • Daily Power Usage: 4.2 kWh
  • Electricity Price: $0.15/kWh
  • Monthly Cost: $18.90
  • Seasonal Cost (120 days): $75.60
Densely Populated Areas in Canada Example
  • Daily Power Usage: 4.2 kWh
  • Electricity Price: CAD 0.13/kWh
  • Monthly Cost: CAD 16.38
  • Seasonal Cost (150 days): CAD 81.90

These costs are manageable, but leaving cables on unnecessarily can waste energy. Our Roof De-icing Cable Controller reduces costs by activating only when needed, based on temperature and moisture, ensuring energy-efficient operation.

This controller activates the heating system based on both temperature and moisture levels, ensuring it only runs when snow or ice is present. By avoiding continuous operation, it helps you save energy and reduce overall operating costs without compromising your roof's protection.

Yes, with the "Smart Life" app, you can control the roof de-icing system remotely, whether you're at home or away. This provides added peace of mind and ensures your roof remains protected even if you're not around.

Questions & Answers

  • We have 1-2 feet of snow on roof, ice at eaves. The controller did not turn on. On app in ‘auto’ mode the app says sensor “dry”. Do I have a bad controller or sensor? The sensor is installed as per instructions, approximately 12” above the heat wire loop. The controller will operate if I change mode to ‘manual’, which we are obviously doing at this time. Is there a way to test if its controller issue or sensor?

    Dear Michael,


    Thank you for reaching out to us with the issue you’ve experienced with your roof de-icing controller.


    First, we want to confirm that the controller and sensor are not faulty—this is clearly proven by the fact that the controller works perfectly when you switch it to manual mode. 


    Our roof de-icing controller is engineered with a specific safety and efficiency design principle: The roof control is designed to energize the roof de-icing cables ONLY when roof snow/ice melting conditions exist AND there is a risk of this melt water refreezing at the roof edge to form an ice dam. The RDC (Roof De-icing Controller) temperature sensor detects the ambient temperature, and the sensor wire senses the presence of liquid water. The controller will only supply power to the heating cable when two conditions are met simultaneously: the ambient temperature is below about 3°C (38°F), and the sensor wire is in direct contact with water.


    Even though there is 1-2 feet of snow and ice on your roof and eaves, the sensor is showing "dry" on the app, which means the sensor wire is not making contact with melted liquid water from the snow and ice. This is the reason the automatic mode fails to activate—our system is designed to respond only to liquid water, not snow or ice itself.


    If you have any further questions or need additional guidance on adjusting the sensor, please don’t hesitate to contact us at any time. We’re always here to help.

  • What is the top wattage that it can handle being plugged into it?

    Hi Missy,​

    The top wattage that it can handle is 1800 watts (with a maximum current of 15 amps).
