Roof restorations are more than just replacing damaged shingles or tiles. They also include the implementation of preventative measures to safeguard your roof against future damage. One such preventative measure is the installation of roof heat cables.

Understanding Roof Heat Cables

Roof heat cables, also known as heat tapes or de-icing cables, are designed to prevent the formation of ice dams on your roof. Ice dams occur when snow melts on the warmer parts of the roof and refreezes on the colder parts, particularly the eaves. Over time, this can cause significant damage to your roof, leading to costly repairs.

The Pros and Cons of Installing Roof Heat Cables

While roof heat cables can be an effective solution for preventing ice dams, they come with their own set of advantages and drawbacks.


  • Prevention of Ice Dams: The primary benefit of roof heat cables is their ability to prevent ice dams, protecting your roof from potential damage.
  • Cost-Effective: When compared to the potential cost of repairing damage caused by ice dams, the installation of roof heat cables can be a cost-effective solution.
  • Easy to Install: For most homes, the installation of roof heat cables is a simple process that can be completed within a day.


  • Energy Consumption: Roof heat cables use electricity to generate heat, adding to your energy consumption and potentially increasing your electricity bill.
  • Maintenance Required: Like any electrical system, roof heat cables require regular maintenance to ensure they continue to function effectively.
  • Aesthetics: For some homeowners, the presence of roof heat cables may detract from the aesthetic appeal of their home.

How Roof Heat Cables Contribute to Roof Restorations

When undertaking roof restorations, it’s important to consider not just the current state of your roof, but also potential future issues. By installing roof heat cables, you can prevent the formation of ice dams, thereby extending the lifespan of your roof and reducing the need for future restorations.

Determining Your Roof Heat Cable System Needs

Before installing roof heat cables, you’ll need to assess your roof to determine the amount of cable required. This includes measuring the length and depth of your eaves, the length of each downspout, and any other areas where ice tends to accumulate.

Choosing the Right Type of Roof Heat Cable

There are two main types of roof heat cables: constant wattage and self-regulating. Constant wattage cables generate the same amount of heat regardless of the outside temperature, while self-regulating cables adjust their heat output based on the ambient temperature. For most homes, self-regulating cables are the more effective and energy-efficient option.

The Importance of Roof Clips for Heat Cable Systems

Roof clips are essential for securing your roof heat cables to your roof. They ensure the cables are laid out in an effective pattern and remain securely in place, even in harsh weather conditions.

Tips and Tricks for Heat Cable Installation

  • Check Your Power Source: Make sure you have a suitable power source close to your roof. You may need to hire an electrician to install a grounded outlet if one is not already available.
  • Plan Your Layout: Use chalk to mark out your cable layout on your roof before installation. This will help you work out the best placement for your cables and clips.
  • Don’t Pull Too Tight: When installing your cables, make sure they are taut but not overly tight. Overstretching the cables can put unnecessary stress on the system and lead to damage.

Installing Heat Cables on Metal Roofs

Installing heat cables on metal roofs requires a slightly different approach. For these types of roofs, you’ll need to use special clips that can be securely attached to the metal surface.

Maintaining Your Roof Heat Cables

Like any part of your home, your roof heat cables will require regular maintenance to ensure they continue to function effectively. This includes checking the cables for damage, ensuring the clips are securely attached, and testing the system regularly to ensure it is generating heat as expected.

When to Call a Professional

While the installation of roof heat cables can be a DIY project, it’s always a good idea to call in a professional if you’re unsure about any aspect of the installation. A professional can ensure the cables are installed correctly and safely, and can provide advice on the best types of cables and clips for your specific roof.


Roof heat cables can be an effective part of your roof restoration strategy, helping to prevent ice dams and extend the lifespan of your roof. While they do require an initial investment and ongoing maintenance, the protection they offer against potential roof damage can make them a worthwhile addition to any home.

Roof restorations encompass more than just repairing damaged shingles or tiles; they also involve proactive measures like installing roof heat cables. These cables, also known as heat tapes, play a crucial role in preventing ice dams, which can cause significant damage over time. While they add to energy consumption and require maintenance, roof heat cables are cost-effective compared to potential repairs from ice dams. By extending the lifespan of your roof and enhancing its durability, roof heat cables contribute effectively to a comprehensive roof restoration strategy
