What Roof De-icing Systems are Best for Heating Shingle Roofs?

When it comes to home maintenance, perhaps nothing is as important as the condition of your roof. While roofs are generally very sturdy and built to last, over time extreme weather or accidents can chip away at the integrity of a roof. That’s why professional roofers suggest that you inspect your roof every spring and winter. Performing inspections might alert you to trouble spots, whereby you can take action to prevent possible problems and save yourself from expensive water damage and major repairs in the future.

Ice dams pose the single greatest threat to roofs in cold climate areas, and often it’s difficult for homeowners to recognize that issues may be developing under the ice dam. Unfortunately, many times the problem isn't discovered until serious water damage has occurred. Ice dams develop when warm air escapes into the attic where it provides just enough warmth to melt the bottom layer of snow that’s on the roof. The water trickles down to the eaves, but because of the overhang, no warm air can reach the eaves and the water refreezes. Eventually more runoff reaches the eaves and soon a ridge of ice forms, causing water to pool behind it. The pooled water typically refreezes at night and then melts again in the day. Water can find the tiniest crack or imperfection in the roof, and as it refreezes, it expands, amplifying the existing problem. Over time water may even enter the home, seeping between walls - and in worst case scenarios, cause mold and mildew to develop.

Roof de-icing systems are designed to eliminate ice dams so that runoff reaches the gutter and flows harmlessly away from the home. Warmzone® offers a variety of trusted roof de-icing systems that can eliminate ice dams from roof eaves, as well as keep valleys, gutters and downspouts free of snow and ice buildup.

Roof De-icing System Control Options

Once you’ve selected the heating element for your roof de-icing system, you’ll want to find the optimum controller. Warmzone offers a wide selection of the industry’s most advanced and proven control devices. You have the option of setting up your system with simple manual control, or full automation with Warmzone’s selection of advanced controllers and thermostats. Warmzone carries only the industry's most reputable roof de-icing system controls and components. A variety of accessories is also available. Call a roof heating professional today to learn more.

The low-voltage RoofHeat STEP systems utilize power units (transformers) that control specific sections of the de-icing system. The transformer steps down high voltage to low voltage (60 V or less), and monitors the power and output of the heating element under the roof to ensure safe, optimal performance. The recommended controller for this system is the advanced TOUCH thermostat.

The activation device of choice for automated roof heating systems using self-regulating heat trace cable is the WS-8C activation device (snow sensor). The sensor is housed in a sturdy NEMA 3R enclosure rated for outdoor use and features a remote precipitation sensor with a 10-foot cable. This allows the user to place the sensor in the roof gutter while mounting the unit in a more convenient location.

Manual control options are also available from Warmzone. Call a roof de-icing expert today to learn more about the available controls, and which would be best for your roof heating system. Call us today at 888-488-9276.
