    What Does Our De-Icing Cable Service Include?

    De-icing cables create a heated path along the roof edge, through the eavestrough, and down the downspout so meltwater can drain freely rather than refreeze into an ice dam.

    Roof Edge Cable Installation

    We install de-icing cable in a zigzag pattern along the roof edge where ice dams most commonly form — just above the eave line, over the overhang, and into the gutter below. The system uses low-wattage resistance cable to maintain a clear drainage path during freezing conditions.

    Eavestrough and Downspout Cable Installation

    Ice forming inside the eavestrough and blocking the downspout is as damaging as ice on the roof itself. We run cable through the full length of the gutter channel and thread it down through the downspout to ground level, ensuring the entire drainage path from roof edge to discharge point stays clear.

    Problem Area Targeting

    Some roofs have specific sections that ice dams more severely due to shading, roof pitch, valley configuration, or heat loss patterns from the attic below. We assess your roof before installation and target cable placement at the areas most likely to cause problems, rather than cabling the full perimeter unnecessarily.

    Electrical Connection

    De-icing cables require a properly grounded outdoor electrical outlet. We route and position the system for connection and coordinate with the homeowner or electrician where required.

    De-Icing Cable Services in Toronto, Mississauga & the GTA

    Ice dams form every winter on Toronto homes where heat escapes through the roof and refreezes at the cold eave edge. A properly installed de-icing system prevents the cycle before it starts.

    Why Choose Century Aluminum for De-Icing Cable Installation?

    We install de-icing cables as part of a full roofline assessment – not as a standalone product drop. We identify where your roof is most vulnerable to ice dam formation, run cable along the roof, eavestrough and downspout as a complete drainage path, and connect the system correctly to a grounded supply.

    Cable routed through eavestrough and downspout, not just the roof edge

    Problem areas assessed and targeted before installation begins

    Signs Your Home Needs De-Icing Cables

    • Ice dams forming repeatedly at the same roof sections: A persistent pattern means your roof geometry or insulation creates a consistent freeze point at the eave edge.
    • Icicles hanging from the eavestrough every winter: Large icicle formation indicates water is flowing off the roof, freezing in or above the gutter, and accumulating rather than draining.
    • Water staining on interior ceilings or walls near the eaves: Ice dam backup has pushed water under shingles and into the roof structure.
    • Eavestroughs pulling away or deforming under ice weight: Heavy ice buildup inside the gutter is stressing the brackets and fascia beyond their design load

    We used Gary and his team to replace the original, 30-year-old eavestroughs on our home with a better, modern system. His quote was good, he showed up exactly when promised, and did a great job. We will use Century again if we need more work done. Thanks Gary!

    Gary was great to work with through the entire process. I reached out for a quote and Gary was quick turning that around and was really helpful in answering all my questions. When it came time to do the work, he walked me through the work he would be doing in detail. The new eavestroughs look amazing, they did such a great job! I'd happily hire Gary and team again.

    We were very happy with Gary and his team at Century Aluminum as they replaced our downspouts and eavestroughs complete with leaf guard protection. Gary kept his appointments and his word. The work was completed as promised and the site was kept tidy and thoroughly cleaned up after the work was completed. His team was courteous and professional. We strongly recommend Century Aluminum.

    Gary did an outstanding job repairing my eavestroughs, and I am completely happy with the results. His communication was fast and clear from the start, keeping me informed every step of the way and even fit me in earlier when he had an opening. He took the time to offer different options to fix the issue and helped me choose the best path forward. The quote was transparent with no hidden surprises, and the work itself was finished quickly and effectively. Most importantly, after a recent heavy rain, I can confirm there is no leaking at all. I strongly recommend Gary to anyone needing eavestrough repairs and would hire him again. Five stars.

    We had an excellent experience with Gary from Century Aluminum. A smallish job needed to be done redirecting a downspout. Gary explained options, including cost effectiveness, and booked that job relatively quickly between their larger commitments.

    Very pleased with the professionalism, workmanship, and responsiveness of Gary and his team. They completed the work exactly as requested and quoted, and I would bring them back for another job in a heartbeat. They corrected the pitch of my eavestroughs using new material and strategically repositioned the downspouts to address a longstanding drainage problem. I now feel much more confident that my property is better protected from future water issues.

    I recently had Century Aluminum come out to reinstall a fallen fascia panel and seal the window capping on the sides of my home. From start to finish, the experience was excellent. They were prompt in responding to my inquiry and came in at a fair price. What really stood out was their honesty — they used the existing materials rather than pushing unnecessary replacements, which I genuinely appreciated. It's refreshing to deal with a company that puts the customer's best interests first rather than upselling at every opportunity. The team was friendly and professional throughout, and the work was done well. I'd have no hesitation recommending Century Aluminum to anyone in the Toronto area looking for reliable, customer-focused exterior work.

    Gary was extremely informative and patient when he dropped by for quote and that was one reason I went with them instead of the others we got a quote from. The job was done with precision and patience and Gary and his team were quite polite and helpful. They pointed out and helped resolve some of the other issues that weren't in the other contract either. Good service, good experience.

    Looking for Another Exterior Service for Your Toronto Home?

    Eavestrough Replacement

    A properly installed eavestrough system works with your de-icing cables to drain meltwater away from the foundation.

    Leafguard / Gutter Protection

    Keep debris out of your eavestroughs so your de-icing cables have a clear path to drain through.

    Soffit & Fascia

    Proper attic ventilation from well-installed soffit reduces the heat loss that causes ice dams in the first place.

    Frequently Asked Questions About De-Icing Cables in Toronto

    What are de-icing cables and how do they prevent ice dams?

    De-icing cables are electric resistance heating cables installed along the roof edge, inside the eavestrough, and through the downspout. They generate heat at 5 watts per linear foot to keep a drainage path clear so meltwater flows off the roof rather than refreezing into an ice dam at the eave.

    Operating at 5 watts per linear foot, a typical residential installation runs at very low cost per day. A 30-metre system uses roughly the same electricity as a few light bulbs over a full day of operation.

    No, when installed correctly. Cables are clipped to the shingle surface with manufacturer-specified clips, not fastened through the shingles. Installation should be done at temperatures between 10 and 27 degrees Celsius to avoid working with brittle cold shingles or soft warm shingles. We assess conditions before installing.

    Yes, and they should always be run through the downspout as part of a complete installation. An ice dam that forms in a blocked downspout after the eavestrough has been cleared causes the same backup problem. We route cable from the roof edge through the full eavestrough run and down the downspout to the discharge point.

    Yes. Century Aluminum serves residential and commercial properties throughout the GTA, including Mississauga, Oakville, Brampton, and surrounding communities. Contact us for a free estimate.
