    What Does Our Soffit Replacement Service Include?

    Soffit replacement is not just swapping panels. It means removing the old system correctly, inspecting the roof framing underneath, and installing new aluminum soffit with the right balance of vented and solid panels for your attic ventilation requirements.

    Full Soffit Removal and Inspection

    We remove all existing soffit panels and backing material from the full roofline perimeter. Before any new panels go on, we inspect the rafter tails, sub-fascia, and any existing wood backing for rot, moisture damage, and pest entry points. Proper ventilation reduces heat buildup, prevents ice dams, and extends roof life.

    Vented Aluminum Soffit Installation

    Vented soffit panels have perforations that allow outside air to flow into the attic, working with ridge and gable vents to regulate attic temperature. Proper attic ventilation reduces heat buildup in summer, prevents ice dams in winter, and extends the life of your roof shingles. Typically vented soffit is installed along the entire roofline.

    Solid Aluminum Soffit Installation

    Solid panels are used in areas where continuous ventilation is not required or where existing roof venting is already sufficient. We install solid aluminum where the roof design calls for it and coordinate the panel placement with your vented sections for a consistent finished appearance. Porch ceilings are typically finished with solid, non-vented soffit.

    Soffit Replacement Coordinated with Fascia and Eavestrough

    Soffit replacement done in isolation can create integration issues at the fascia and J-channel joints. We plan soffit replacement as part of your full roofline system. We coordinate soffit replacement with fascia and eavestrough to ensure proper fit and reduce total labor.

    Why Choose Century Aluminum for Soffit Replacement?

    We assess attic ventilation requirements before specifying panel types, so the new soffit works as part of your roof system, not just as a cosmetic finish. Vented and solid panels are placed where they are needed, not distributed arbitrarily.

    Signs Your Soffit Needs Replacing

    • Sagging, cracked, or missing soffit panels: Sections pulling away from the fascia or showing visible deterioration that repair cannot address
    • Pest entry at the roofline: Gaps or holes in deteriorated soffit giving birds, squirrels, and insects access to the attic cavity
    • Ice dams forming repeatedly along the roofline: Often a symptom of inadequate attic ventilation caused by blocked or insufficient soffit venting
    • High attic temperatures in summer: Inadequate soffit ventilation traps heat in the attic, increasing cooling costs and stressing roof shingles
    • Water staining on interior ceilings near the eaves: Moisture in the attic caused by poor ventilation or damaged soffit panels allowing water infiltration

    Gary was recommended by a friend, and he did a great job putting new siding on our house. Very professional, reasonable price, and easy to work with. He provided lots of options, answered all of my questions, and paid attention to the finer details, which shows he takes pride in his work. He even took some of the scrap that I had sitting around after some demolition I had done in preparation for Gary and team. I would absolutely recommend Gary to anyone who needs siding or aluminum work.

    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.

    Frequently Asked Questions About Soffit Replacement in Toronto

    How do I know if my soffit needs replacing or just repairing?

    Repair is right for localized damage to a few panels with sound backing behind them. Replacement makes more sense when damage is widespread, the system is wood or aged aluminum past its service life, or ventilation is inadequate across the full roofline.

    Vented soffit has perforations that allow outside air into the attic. Solid soffit has none. Most GTA homes need a mix of both, with vented panels along the roofline to maintain proper attic airflow.
    Yes, when vented panels are correctly specified. Proper soffit ventilation reduces summer heat buildup, prevents winter ice dams, and extends shingle life. Older homes with solid wood soffit typically see a meaningful ventilation improvement after replacement.

    In some cases, yes. Soffit can be replaced independently. Combining it with fascia or eavestrough work on the same visit reduces labour cost and ensures all components integrate cleanly at the joins.

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