Key Notes

  • The cost of heat tape varies between approximately $1 to $3 per linear foot for materials and between $5 to $15 per linear foot for professional installation.
  • Heat tape typically consumes between 3 to 5 watts of power per linear foot per hour with monthly running costs ranging between $40 to $200. 
  • There are two main types of heat tape – self-regulating and constant wattage
  • Proper installation is important to maximize efficiency and lifespan.

How Much Does Heat Tape Cost To Run?

According to Home Guide, heat tape typically consumes between 3 to 5 watts per foot, making its operational cost an important consideration in your overall energy consumption. 

As an example, a 30-foot heat tape uses about 90 to 150 watts per hour. Based on average electricity rates, this translates to an operating cost of roughly $1 to $2 per month per 10 feet.

Bear in mind that monthly running costs can range from $40 to $200, depending on local electricity rates and usage patterns.

Heating Cable Installation Costs

The installation costs for roof heating cables range from $5 to $15 per linear foot, with total expenses typically falling between $500 and $2,000. Let’s break these costs down into the main components.

1. Materials

self-regulating cables

The biggest factor in your cost calculations is the type of heat tape you choose and you can expect to pay anything between $1 and $15 per linear foot. The two main categories are self-regulating cables and constant wattage. Let’s break down both of these.

Self-Regulating Heat Tape

These smart roof heating solutions adjust their power output based on ambient temperature, increasing heat output when it’s cold and decreasing when it’s warm. This reduces your long-term operating costs, resulting in significant savings on your electricity bills, especially in varying climates.  

For this reason, self-regulating heat tape is a popular choice for energy-conscious households wanting to cut down on energy wastage. 

Here are some other advantages of self-regulated heat tape:

  • Safety: Self-regulating heat tape reduces the risk of overheating and fire hazards because it automatically decreases its power output as temperatures rise. This makes it safer for long-term use compared to constant-wattage cables.
  • Ease of Installation: These cables can be cut to length during installation, simplifying the process and potentially reducing labor costs. They are also easier to install on complex roof structures.
  • Durability: Self-regulating cables tend to have a longer lifespan due to their ability to prevent overheating. This durability translates into fewer replacements and lower long-term maintenance expenses.

Constant Wattage Heat Tape

As its name suggests, constant wattage heat tape provides a consistent level of heat, regardless of the weather and ambient temperature. 

Although cheaper these non-regulating products can cost you in the long run as they tend to be less energy efficient and can lead to higher electricity bills.

2. Labor

If you’re using a professional installer you can expect to pay between $50 to $200 per hour for fitting. For an average-sized roof between 150 and 300 linear feet, installation can take between 4 and 8 hours.

Bear in mind that this price can change according to the complexity and length of your installation and that labor prices fluctuate seasonally and increase when demand is high.

Accessibility is another aspect to consider. If your roof is steep, you have multiple stories or lack internal access, your labor quotation may be higher.

Labor costs for professional heat tape installation are usually cheaper in summer when demand is low.

3. Roof Type and Size

The complexity and size of your roof will have a significant effect on your installation costs. Larger roofs with multiple angles or those with dormers, valleys, and longer eaves need more cable, making them more expensive than simple roofs. 

Also consider the placement of your cables, as most heat cables are attached in a zig-zag pattern. This melts more snow but also increases your material needs.

4. Additional Components

Some homeowners choose to automate their heat tape systems with temperature sensors and other control mechanisms. While more convenient, it adds to your overall cost. 

For instance, an automatic cable control thermostat sets you back between $40 to $120, however it can save electricity when added to a manual roof heat cable.

Additional ComponentsCost
Automatic Cable Control Thermosta$40 - $120
Clips, Fasteners, Electric Tape$10 - $50
Outdoor-Rated Extension Cord$20 - $100
Ladders$50 - $300

5. Peripherals and Extras

Besides heat tape, you’ll need a few extra components before you’re ready for installation, especially if it’s a DIY job. Here are the main points to consider. 

  • Equipment and consumables – such as an automatic thermostat or a manual controller
  • Clips, fasteners and electric tape – to securely install your heat tape
  • Outdoor-rated extension cord – to provide electricity to power tools
  • Ladders – for easy access to your roof
