How it works:

Heat Tape Pro

The backbone of your roof and gutter de-icing system, HeatTapePRO™ is the only heat cable with a GlowCap, so you know it’s working.

Roof Clips

Roof clips are what hold your cable in position. We offer a wide variety but only GripClips™ are specially-designed for the fastest, simplest installation.

Heat Tape Controller

ThermaCord™ adds greater efficiency to your de-icing system by automatically turning your cable on and off when the weather calls for it.

Cable Guard

Don’t let sharp points and edges ruin your new system! CableGuard™ pinches around your cable, protecting it at the top and bottom of downspouts.

  1. Measure the linear feet of roof eave (A) that you want to protect from ice dams
  2. Measure the depth of the eave (B)
  3. Note any valleys in the roof (C) that exist where the heat cable will be installed
  4. If there are gutters, make note of the number of downspouts

Large Job Options

If your heat cable project requires more than 150 feet, you have two simple options: Use a pair of our plug-in ready HeatTapePRO cables or, hardwire a single 240 volt cable from a spool.

Option 1:

Two Plug-in Cables

Requires Two Outlets on Different Circuits

It’s often possible to use two standard, plug-in ready HeatTapePRO cables to addess larger areas. You will need to plug the cable into separate outlets on different circuits. Remember, all HeatTapePRO cables have a 10-foot length of power cord not included in it’s stated length.

To use two plug-in cables, divide your planned layout into two sections, and calculate the length needed for each.

Option 2:

A Single 240 Volt Cable

Hardwired: Requires a Junction Box

You can install a lot of our 6 watt, 240 volt heat cable on a 240 volt circuit. Although our plug-in cable has a top length of 150-foot, installing spooled cable is identical to pre-assembled cables with the exception of connections and terminations. You must terminate the end of your cable with either our traditional End Seal Kit, or our popular GlowCap End Seal Kit. You will also need to connect your heat cable to a junction box fed by 240 volts using our Hardwire Connection Kit. Connection kits take about 10 minutes to execute.
