Do I need to cover my entire roof with heating cable?

No, you do not need to cover your entire roof with heating cable.

It is important to identify the “problem areas” and to create a path down the gutters and spouts for the melting snow and ice. This is especially true for tight valleys or on low-pitched roofs where gravity and northern exposure can prevent natural melting.

Typically, the lower 2ft of the roofline, and the gutters and spouts get heated. For more detailed recommendations, please refer to the installation manual.
