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

Depending on the roof angle, asphalt shingle roofs may not handle snow load, ice dams, and icicles build-up well, which can result in costly damage. These types of roofs typically require a properly designed heating cable deicing system to help mitigate the worst effects of winter.

When ice and snow accumulates on a roof, inside of gutters, or on/in a roof's valleys, it can cause costly water damage to your home or business.

A WarmlyYours Ice Shield Roof & Gutter Deicing System provides a reliable solution for ice damming that occurs on asphalt shingle roofs, especially in the problematic areas like valleys, dormers or simply where the pitch is not steep enough to allow melted snow and ice to flow away safely.

What is the Best Deicing Cable for Heated Asphalt Shingle Roofs?

Self-Regulating vs. Constant Wattage Heating Cables

There are two different kinds of heating cables for roof and gutter deicing systems: self-regulating and constant wattage. Both can serve the same purpose, although the application will typically determine the best solution for the job.

Self-regulating heat cable has a special conductive core between the 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 pipes in the winter from freezing or for keeping gutters clear of ice formations. 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.

Constant wattage heat cable is a heating cable that has the same wattage per linear foot (power output), throughout its entire length. Since this cable is generally not affected by varying ambient or pipe content temperatures, it provides a constant heat output.

Constant wattage heating cable is preferred for homeowners who want to ensure that environmental conditions will not affect their heating output.


How to Measure Your Asphalt 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 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.

How to Install Asphalt Shingle Roof Deicing Cables

The first step is to ensure that you have the proper length of cable for your heated asphalt shingle 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. Add clips before and after each downspout.

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.
