Advantages of installing roof de-icing cables Roof snow removal is still important when there is a thick layer of snow, even if the roof is equipped with de-icing cables. The channels allow meltwater to flow off the roof instead of freezing into ice dams or seeping into the roof.ĭe-icing cables cannot melt all of the snow on the roof or completely prevent ice dams. Roof de-icing cables use electrical resistance to generate heat, melting pathways through the snow and ice on the roof. How can roof de-icing cables help prevent ice dams?

Ideally, the roof’s temperature should be the same as the ambient temperature outside, so that the snow covering the roof will melt at the same rate as the snow outside the thermal bridge. What causes ice dams?Īfter a heavy snowfall with temperatures below freezing, roofs can be covered with a thick layer of snow. One of the most popular strategies isĪrticle, find out how ice dams form and how roof de-icing cables can helpĬounteract the process.
