Roof windows are often covered by snow in the winter. When the temperature rises, the snow starts to melt because of heat leakage through the window. The melted snow runs off the window to the colder roof surface further down. The melt water freezes into ice, because the snow below the window prevents further run off. A pool of dammed-up water collects under the ice. This can cause water to begin ...

The material costs are similar. However, electric systems are easier to install, with fewer components and significantly lower maintenance costs. Electric systems will run for a shorter period of time to give the same level of performance but with much higher energy efficiency (typically 95%-98% efficient). Controls and sensors required for the two types of systems are very similar. Electric syste...

Always confirm the power requirements with the electrician. Large snow melting systems usually require a new electrical panel or electrical service. Contact us for a quotation, indicating the actual power capacity available, and to obtain recommendations for reducing the power consumption. For example, opting for tire track coverage rather than installing the snow melting system over the entire dr...
