Roof & Gutter De-icingHome Depot Gutter

Many roof leaks are the direct result of snow and ice build-up in the gutter or along the roof edge. These ice dams create excessive pressure on the roofing material. The result is lifting and damaging the seal. When the ice melts, the water has no path to the gutter and/or down-spout and infiltrates into the structure.

During winter the temperature is often around zero degrees. At these temperatures large collections of ice and snow are often found on roofs and in gutters. This ice and snow can easily create hazardous safety concerns, especially when ice is falling from above. Installing Nexans heating cables on roofs and in gutters reduces the risk of falling snow and ice and ensures proper roof and gutter drainage preventing roof leaks and structural damage.

Evaluate the Roof Construction: Warm Roof or Cold Roof?Mount St. Louis Moonstone, Ontario

Warm roof: A poorly insulated roof where heat loss through the roof causes a positive temperature on the roof surface under a layer of snow. Water from melting snow will collect in the cold roof drains and freeze.

Cold roof: A well insulated roof where icing occurs, often in the late winter. Sunshine will melt snow on the roof while the roof drains and gutters may be in the shadow. The melting water will then freeze. Repeated occurrences will harm the roof and split gutters and downspouts.


Add together the total length of roof drains and gutters. The loop in the drain must go to point of discharge above or below grade. Multiply this length by 2 to determine the cable length.
