How Much Does It Cost to Install Roof Heating Cable or Heat Tape?

Heat Tape Cost

De-icing cables cost anywhere from $1 to $6 per linear foot. Self-regulating heat trace costs more than basic, manual options. The biggest factor in determining the price of your heat cable is the size of your roof. The larger your roof, the longer the cable required and the higher the price.

“It’s important to make sure you hire a professional when installing these cables to make sure that you not only get the best use from your investment but also that these cables are installed in a safe manner that will preserve your property for years to come,” says Eric Gonzalez, Expert Review Board Member and president of Regions Commercial Roofing, with locations in five states.

Self-Regulating vs. Manual Cable

There are two types of heat tapes—self-regulating and manual.

Self-regulating heat tape: This type adjusts its own heat output based on the outdoor temperature. 

Manual cable: Also known as a constant wattage cable, this type emits the same amount of heat no matter the external temperature. A heat cable is a simple device and there’s not much difference between brands. Some heat cables run on a thermostat; this type will cost more than a manually controlled system.

Heat Tape Installation Cost

Heat wire costs between $12 and $20 per linear foot to install. This cost varies depending on the difficulty of the project. Steep roofs or difficult-to-access areas can bump up the price of installation. The cost to install a thermostat-controlled system is higher than a manually controlled system. Most roofing installers can complete a job within a day or two.

Heated Gutters Cost

A heated gutter system can cost anywhere from $475 to $4,000, depending on your home. That wide range is due to many factors, including whether you need to install a brand new gutter system.

New Gutter Installation

Gutter installation costs an average of $1,100 for 200 linear feet for simple vinyl gutters, but that price can go up substantially if you opt for aluminum, steel, or copper. With new gutters, you will also pay for installing downspouts, which are located every 35 feet or so and cost between $5 and $8 per linear foot for vinyl or aluminum. 

Retrofitting Gutters

Installing heated cable in existing gutters can cost as low as $475 for 200 linear feet, making it far less expensive than building brand new gutters with heating capabilities.

When to Install Heat Tape

De-icing tape warms up snowy, icy roofs to melt accumulation. This process prevents ice dams but it has some pitfalls, such as:

• Heat tape may increase your energy bill by $40 to $70 per month.

• You must remember to turn it on and off as needed.

• It can be a fire hazard if installed incorrectly.

• Lifespan varies by product.

A pro can add insulation to your roof or improve ventilation to prevent ice buildup; the cost to install insulation runs between $1,400 and $6,300. But when traditional methods fail, heat tape is an option. A local home energy auditor or local roofer can help tell you the best ice removal or prevention option for your home.
