Roofs and gutters

Heating cables are ideal to prevent ice and heavy snow in gutters and roof drains. It has an important safety aspect, as it prevents damage that might be caused by snow, ice and icicles falling down.

Warm or cold roof Examine the roof construction: Warm or cold roof? Warm roof is a poorly insulated roof where the heat loss through the roof construction causes a positive temperature on the roof surface under a layer of snow. Water from melting snow will end up in the cold roof drains and freeze. Cold roof is a well-insulated roof where the problem of ice is caused often in the late winter. Sunshine will melt the snow on the roof while the roof drains and gutters may be in the shadow. The melting water will then freeze.
