    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?

    Damaged or poorly ventilated soffit leads to attic heat buildup, ice dams, and moisture problems. Get a free replacement assessment before it spreads further.

    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

    I've hired Century Aluminum twice, to replace eavestroughs and to install de-icing cables. Gary is great to work with, very thoughtful and professional. I have an unusual roof configuration and he helped me figure out a gutter solution to redirect water from a problem area. The quality of their work is excellent and the pricing is reasonable, too. I would definitely recommend Century Aluminum and I'm sure I'll have them back for future exterior projects.

    Gary and his crew did an excellent job replacing the gutters and downspouts on my house, and everything during the whole process was conducted professionally and honestly. Gary was also very responsive and answered all questions I had before, during, and after the work was completed. Very much appreciated, thank you!

    The team arrived on time, did the repair work quickly and accurately, and gave great advice without trying to upsell services. What I wasn’t happy about was Gary mocking a customer with a disability. If I wasn’t getting work done for elderly family members, I would have kicked the **** out of Gary.

    Gary and his team were very professional and the quality of work is excellent. Everything was seamless from beginning to end. A clear quote was provided detailing scope of work, estimated time for initiation and completion of work. There were some out of scope issues that arose during the installation which Gary fixed without added cost. He even offered to install a new porch light aa ours was broken. Definitely went above and beyond. I’m certain this company will stand behind their product and installation for years to come.

    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.

    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.
