Switches, Sensors, and Timers- Activation Options for Snow Melting and Roof Deicing Systems

When installing Snow Melting or Roof Deicing systems, there are a number of options for activation available. Do you need an automated sensor or will a manual timer work? Do you want the system activated when it snows or just when it is cold? Should you use a pavement mounted or an aerial sensor? With all the options available, let’s take a look at which options Warmquest recommends for various solutions.

Manual Timers
Timers and other manual switches are recommended with most of our systems. These options are great for pairing with an automated sensor to provide the option to manually activate the system if needed.

A manual switch may be sufficient on its own for activating a system in a less critical area. If you would be alright with waking up in the morning to a snow covered driveway or arriving at the office and finding snow built up from an unexpected storm then a manual timer will likely suffice. It is important to note that it accumulated snow acts as an insulator and is harder to melt than falling snow.

Temperature Sensors
Temperature sensors are most commonly used in conjunction with our roof deicing systems. Particularly for commercial and other critical areas, a temperature sensor will operate the system whenever the temperature is below a configurable temperature point. This is useful for roof deicing as ice dams are frequently caused by snow melting and refreezing on the cold roof.

Some sensor models also have a temperature floor which turns the system off when it is below a set point, or too cold for melt to occur. This allows our systems to be more efficient.

Snow Sensors
Combination temperature and moisture sensors are our recommendation for most snow melting applications. These sensors activate a system when the temperature falls below a set point and moisture is detected on the sensor head. This ensures the snow melting system will run during a storm and for a configurable amount of time after.

When selecting a snow sensor, you have several options. The most common distinction is whether the sensor is aerial mounted or embedded in the pavement. Our pavement mounted sensors offer the most flexibility, with the controls for configuring the sensor mounted separately from the sensor head. This allows the controls to be configured from indoors.

Aerial mounted snow sensors typically mount along the roof eave, in a clear area where they will catch falling snow. This means to avoid trees, overhangs, and any other obstacle that could prevent the sensor from activating.

We advise you discuss your project goals and needs with a Warmquest expert to decide on the best activation option for your system. With more options available all the time, including wi-fi and other smart home technologies, Warmquest can provide a solution tailored to your project.

Roof Drainage Solutions

Drainage is important for any roof, but becomes particularly critical on flat roofs. In cold climates, snow and ice accumulation can quickly snarl drains and downspouts, preventing snow and water from leaving the roof. This can lead to many hazards, from snow load concerns to slippery surfaces in maintenance areas.

Managing snow and ice on commercial roofs is difficult. If drainage is not maintained, not only can snow load issues arise, but even on the best engineered roofs ice damming can become an issue. As ice builds up in and around drains, water is unable to escape the roof and often finds its way inside.

Warmquest frequently works with architects, engineers, facility managers and others to provide roof and drain deicing solutions. Our under roof heating options provide a permanent, long lasting fix to drains freezing and backing up. These unique low voltage systems can be installed beneath membrane, shingle, metal and other roofing materials. 

For a flat roof with drains, the ideal solution would be to install an under roof deicing system in the areas around the drains. This keeps the area clear and free of snow and ice buildup. Then, loop self regulating cable like our GutterMelt product down into the drains. This cable should extend to conditioned space, daylight, or below the freeze line. The GutterMelt will keep water flowing in the drain itself.

Rather than attempting to shovel the roof, let Warmquest help you heat it. With our Invizimelt and ZMesh under roof deicing systems, you can melt around drains, along walls, and any other trouble spots. These systems are installed beneath the roofing material and heat entire sections of roof.

How do Self-Regulating Cables Work?

Warmquest’s GutterMelt SR is an industrial grade, self-regulating, heat trace cable for deicing gutters, downspouts, roofs and pipes. Self-Regulating cable functions differently than the other constant wattage systems we carry. Self-Regulating cables like GutterMelt vary the heat output in accordance with the ambient air temperature. This can sound like voodoo or witchcraft, so let’s take a closer look at the mechanics of Self-Regulating technology.

Now Available at Warmquest: Pedestal Paver Snow Melt System

Warmquest is thrilled to introduce the Pedestal Paver Snow Melt System, the latest in our line of roof deicing and snow melting products.

Pedestal paver systems are a popular choice in rooftop living spaces, hardscapes, green roofs, and many other applications. Typically, large pavers are elevated on pedestals to accommodate drainage below.

The Pedestal Paver Snow Melt System allows our mineral insulated Hott-Wire cables to be easily installed directly beneath the pavers. The panels provide an effective heatsink, spreading the heat from the cables across the entire surface of the paver above. The panels are insulated from below to drive heat upward to the pavers.

The panels are laid out over the pedestals, without compromising drainage or interfering with the paver installation. The end result is effective snow melting and a space that can be used all winter long.

The Warmquest team can provide a customized heating system for your pedestal paver solution. Give us a call at 877-877-4724.
