With winter fast approaching, home and business owners alike are checking the conditions of their roofs and taking steps to prepare for the impending snow and ice storms. Clearing gutters and checking the condition of shingles and flashing every fall is crucial for proper roof maintenance.

While some property owners install ice guards to prevent large slabs of ice from falling and injuring pedestrians or damaging vehicles, many opt for a more comprehensive approach when it comes to safety – and roof maintenance. 

Roofs are typically designed to withstand significant weight loads, so the volume of snow on a roof is usually not an issue. (Roofs are typically designed to withstand a snow load of 30 pounds per square foot, depending on your location and elevation). Radiant roof heating systems aren’t typically used to keep entire roofs free of snow; rather, the de-icing systems are designed to enhance safety and prolong the lifespan of a roof by keeping specific areas free of snow and ice. In general, de-icing systems are installed to prevent problems by facilitating steady runoff and eliminating any troublesome areas where ice often accumulates.

Keeping roof edges clear of snow and ice helps to ensure safety for pedestrian traffic, but perhaps the single most important function of a roof heating system is to prevent ice dams from forming. In this regard, a roof de-icing system can be a real money saver.

Ice dams are the most prominent culprits when it comes to roof damage and expensive water damage inside the home. If an attic isn’t properly insulated, warm air can escape from the home into the attic. There, the warm air rises and slowly warms the roof. The underlying layer of snow on the roof then begins to melt. It trickles down to the roof eave, but because the overhanging eaves aren’t heated by the attic air, the water tends to re-freeze. As this process repeats, eventually a ridge of ice forms on the eave. That ridge grows and gets to a point where water begins to pool behind the ridge. This is where the real trouble starts.

As water pools behind the ice dam, the water can seep into every tiny nook and crevice in the roof. When the water refreezes at night, it expands, and over time, those tiny cracks in the shingles and roofing grow. It’s a slow process, but eventually those cracks can turn into large cracks that allow water to seep into the home.

Perhaps the most affordable way to prevent ice dams from forming is to install self-regulating heat trace cable. ProLine’s cable is an industry leader, and can be easily installed along roof eaves, valleys, and in roof gutters. Using cable clips, the heat cable is installed in a repeating V pattern along the eave, which provides channels for the runoff to reach the gutter. This system is easy to customize, and is the most popular de-icing solution.

Entire roof eaves can also be heated. ProLine’s low-voltage STEP^® roof heating system is often used to keep roof valleys, eaves, and other areas completely free of snow and ice. The system features thin, self-regulating heating panels that are installed neatly under shingles or metal roofs. Transformers are used to step down the high voltage to low voltage (60 V or less) while controlling specific sections of the roof de-icing system.

The flexible heating element is polypropylene fused during fabrication to achieve water proofing and protection from alkaline or salt damage. This versatile system can be used to heat just about any type of roofing material. The heating element is available in widths of 3, 6, 9 or 12 inches. The low-voltage element is easy to install and can be cut to size on the job site. It can be nailed or stapled through, making installation quicker and easier than other traditional roof heating systems. Because the heating element is self-regulating, when the ambient temperature rises, the electrical resistance increases and the consumption of electricity decreases. This prevents the element from overheating and ensures energy-efficient operation.

What are the Best Roof De-icing Options?

When it comes to protecting roofs (and pedestrians), there are several roof de-icing options available from ProLine. Customers can heat entire roofs, roof eaves, or simply keep roof valleys and gutters free from snow and ice.

ProLine roof heating systems can be fully automated, and they’re not difficult to install. The systems range from individual lengths of self-regulating heat cable to heated aluminum panels and thin, low-voltage heating panels that can be installed discreetly under the roof shingles.

Typical automated roof heating systems utilize a main snow/ice sensor that activates the de-icing system when moisture is detected and the temperature is below the adjustable setpoint. This results in a very cost-effective solution for heating large areas of the roof. ProLine’s master control unit is the industry’s premier control unit, and is ideally suited for virtually all types of residential and commercial applications.

Outdoor temperature sensors can be used on roofs and in roof gutters. Moisture sensors and wire sensors are normally fitted inside gutters where the melted runoff collects. The number and placement of these sensors depends on the size and nature of each individual roof de-icing system.

The Most Popular Options

The two most common roof de-icing options are ProLine’s low-voltage heating panels, and self-regulating heat cables. Both systems have proven extremely reliable and effective. The ideal system for your customers’ installation depends on their specific needs.

ProLine’s low-voltage roof de-icing system is extremely popular among professional roofers. This system features thin (only 3/64-inch thick), flexible polymer heating panels that are polypropylene fused during fabrication for added protection from alkaline, UV rays and salt. The panels are designed to be installed under the shingles or roofing material. (This system is also safe to heat metal roofs.)

Another advantage of the low-voltage panels is that they are self-regulating, so the heating element efficiently increases the heat output as the outside temperature falls and decreases the heat output as the temperature rises. The heating element can also be nailed or stapled through, and cut on site. (However, take care to avoid nailing through the bus braids at the edges of the heating element.) Low-voltage panels are available in widths of 3, 9, and 12-inches.

The low-voltage system includes an activation device (snow sensor) and a step-down transformer. Each transformer is responsible for a specific section of the de-icing system, and can step down from high voltage to low voltage (60V or less). It is the source for monitoring the power and output to the system heating element to ensure safe, accurate performance. ProLine’s low-voltage system is one of the most advanced and efficient roof heating systems on the market today.

ProLine self-regulating heat cable is the most affordable option for home and business owners who are looking to eliminate ice dams and trouble spots on their roof. Self-regulating roof and gutter heating cable features advanced technology that results in highly effective, energy efficient operation. The irradiated conductive core increases its heat output as the temperature falls, and decreases its output when the temperature rises. The heat cable’s self-regulating core ensures that the cable will also not overheat or burnout if the cable is overlapped or touching. The durable heat cable can be easily installed along roof edges and in gutters and downspouts to facilitate runoff.

By zigzagging the heat cable along the roof eaves, channels are provided for runoff so that no ice dams form. The cable is also commonly installed in roof valleys as well as specific areas that are typically problem spots during the winter. Self-regulating heat cable can be easily installed to heat specific areas, and the systems are very affordable.

A great advantage of working with ProLine is that customers not only receive radiant heat solutions at wholesale prices, but that the systems are backed by preeminent customer support services. ProLine includes free installation training, professional system design, and technical support for installers.

These services have established ProLine as an industry leader, and are responsible for a great deal of repeat business from contractors and professional builders. Contractors know that when they install ProLine radiant heat solutions, they’ll receive dedicated, personal support throughout the installation process.
