What is Roof and Gutter Deicing and Why Do You Need a Heated Metal Roof?

While metal roofs are usually better at handling snow load, ice dams, and icicles build-up, they are still not an alternative to a proper heating cable deicing system.

Ice and snow accumulating on the roof, inside your gutters, or in the metal roof valleys can cause costly water damage to your home or business.

WarmlyYours Ice Shield Roof & Gutter Deicing Cable System provides a reliable solution for ice damming that occurs on metal roofs, especially in the problematic areas like valleys, dormers or simply when the pitch is not steep enough.

What is the Best Deicing Cable for Heated Metal Roofs?

What is the Best Deicing Cable for Heated Metal Roofs?

There are two different kinds of heating cables for roof and gutter deicing systems: self-regulating and constant wattage. However, only self-regulating cable can be used for heated metal roofs because constant wattage cables are not approved for that kind of application.

So what is self-regulating heating cable? It’s a unique and energy efficient type of heating cable that has a special conductive core between two bus wires. This core becomes more conductive during cold ambient conditions; therefore the heating cable will increase its wattage per linear foot in response to the cold.

This feature makes it ideal to help protect the perimeter of your roof from ice dams and for keeping gutters clear of ice formations in the winter. This type of cable will also decrease its power output (watts per linear foot), in warmer conditions, when the higher temperature will make the special core less conductive, which helps limit wasted energy.


How to Measure Your Metal Roof for Deicing Cables

For the best installation, be sure to have accurate measurements of the roof and gutter areas that you want to heat.

Additional details like metal roof seam spacing, overhang width, downspout & valley length would be helpful for a detailed and efficient cable layout design.

Marking the most problematic areas where ice formation is most damaging is also very helpful to ensure that the design of the heating system will have extra coverage in those areas.

Your WarmlyYours account manager will provide you with the assistance that you need to get the correct measurements. Once your measurements are completed, you will be contacted to discuss your options and to provide you with an accurate, no obligation quote and SmartPlan prepared for you by our engineers.

Self regulating bundle for roof and gutter deicing

These deicing systems are self regulating, meaning the heating cable will increase or decrease its power output (Wattage per linear ft) in response to how cold or warm each section of the cable is.


  • Available in lengths of 50, 100, 250, 500, and 1,000 ft.
  • Energy Efficient
  • 5-10 Watts per linear ft at 120/240 VAC (self regulating)

How to Install Metal Roof Deicing Cables

The first step is to ensure that you have the proper length of cable for your heated metal roof. A WarmlyYours account manager can help you figure this length out. Then, make sure the roof, gutter and downspouts are free from debris, leaves, pine needles or any combustibles. Double-sided tape pads can only be applied to roofing materials at temperatures above 40°F (the minimum installation temperature for the cable is 0°F or -18°C).

When attaching cable in the gutter, use clips every 10 feet. For roof valleys, run the heating cable two-thirds of the way up and down the valley. Add this additional length to the overall cable length.

Cable Roof installation

Add clips before and after each downspout. Because metal roofs may have damaging snow slides, it's recommend to put in a single pass of heating cable up and down the seam to return to the gutter section below.

Install end seals and power connections before turning on power. The heating device should be connected to weather-resistant, non-heating leads.

After installation is complete, turn the circuit breaker on to give power to the cable. Standing water in the gutter should feel warm within one hour. Adding snow guards on the roof to prevent sliding of snow above can minimize other damages to the roof or gutters below.


Accessories and Controls for a Heated Metal Roof Deicing System

WarmlyYours offers a wide range of controls and accessories to help ensure you get the most out of your metal roof deicing cables.

Our controls range from a basic manual control to our premium option that provides the ultimate in convenience and hands-off operation.

In terms of accessories, the combination of an aerial snow sensor and gutter mounted sensor would be the most effective in detecting snow. We also offer a selection of accessories to ensure your installation process goes as smoothly as it can.
