Expert Soffit Installation & Upgrades in Southern Ontario

Q: What does a soffit actually do?

Honestly, a lot of behind‑the‑scenes work. They help your attic breathe by pulling in fresh air at the roofline, which keeps moisture and heat from building up. They also protect the underside of your roof from pests, rain, and snow.

Q: Can I get soffit in different colours?

Definitely. We offer soffit in a variety of colours from Canadian aluminum brands like Gentek, Royal Building Solutions, and Kaycan. We'll work with you to find a colour that blends in with your siding (and eavestroughs) or stands out with a clean trim look.

Q: What’s a "soffit" when it comes to ceilings?

Inside the home, “soffit” usually refers to a boxed‑in section of ceiling. But on the exterior, soffits are the panels underneath your roof’s overhang—the panels we install and upgrade.

Q: How much does it cost to replace soffits?

The cost depends on the size of your home and whether there’s any underlying damage. During your estimate, we’ll assess everything and provide a clear, detailed quote with no surprises.

Q: How long do soffits last?

If they’re installed properly, aluminum soffits can last 30 years or more. Still, it’s wise to monitor for moisture, peeling, or poor airflow.

Q: Do soffits help prevent ice dams in winter?

Yes, they play a big part. Vented soffits bring cool air into your attic, which helps keep the roof temperature stable—reducing the risk of ice dams at the edge.

It's Crucial: Soffit Matters More Than You Realize

Protect your roofline. Keep your attic breathing. Install soffits that last with expert workmanship and Canadian aluminum. Soffit doesn't just finish the edge of your roof... it's a critical part of your home’s roof ventilation system. Soffit allows air to flow into your attic, reduce moisture buildup, and help prevent ice dams and mold. That's key for longevity and home value.

Looking for high-quality soffit installation?

So... Do I Need Soffit?

It Matters. A lot.

Your home will (literally) fall apart without proper soffit installation. Soffit is the exterior underside of your home’s eaves (the area between the eavestroughs (roof edge) and the siding). It typically includes vented panels that allow cool air into the attic, keeping your roofline ventilated and dry.

Without proper soffits, you risk moisture damage, wood rot, reduced energy efficiency, and a roof at risk of serious structural integrity.

What Our Clients Say

We recently had work done from a recommendation by our neighbors. Great experience from the initial visit when Wendle came out to give us a quote, to the amazing job that Jasmin and his team did for us. We are so happy that we went with this company..

I'm writing this review because they were so important to us when trying to find a company to replace all of our soffit, facia, eaves and downspouts.. It was apparent that this company was providing a well regarded product and people were very happy with the service. They did not disappoint.

I was impressed with the asbestos replacement at my house which was completed on schedule. The work scope and budget were provided early enough and executed without any delay. All materials used were of high quality and up to date..

At all levels, from the estimate to dealing with scheduling, to the job crew, this group was efficient and personable. Communications were fast and friendly, and the job was completed as estimated, and beautifully done..

I couldn't be happier with the results. They took the time to assess my home needs, provided a fair and clear quote. From start to finish, their team was professional, punctual and highly skilled. They completed the job with impeccable attention to detail..

The owner, was reliable, easy to communicate with. He provided honest advice without any pressure or upselling, which we really appreciated. We are glad we decided to work with The Eavestrough Company and we highly recommend them to others..

Company and their owner Wendell where professional, friendly, honest (which is rare in the construction industry) and very helpful. They helped me out big time, pushed my project ahead of time as well. Very well executed, friendly & professional.

Very professional in every aspect! Honest price as well, definitely recommend The Eavestrough Company!

Communication was excellent, and they were able to fit us in before the winter season was in full swing, saving us from another winter of excessive salting in the areas where we had melting/leaking/pooling/freezing..

Excellent experience from start to finish. Wendell, the owner, explained my options and estimated the work and cost. The crew arrived early as scheduled and were professional and courteous, and made sure everything was cleaned up before leaving. Tracy in the office was a pleasure to deal with throughout. Highly recommended!

They were great from start to finish! My house visually looks so much cleaner now and shortly after they left we had a major downpour and it was so nice to no longer see "Niagara falls" pouring out the side of our home!

I needed to install new eavestroughs for my garage.. I am pleased with the work he did. He also showed me how to install and uninstall the extra downspout for the rain barrel, which I needed to put away for the cold weather..

Fascia and Soffit: What’s the Difference?

We often install fascia and soffit together, but they serve different roles:

Fascia is the vertical board that runs along the edge of your roof and holds your eavestroughs in place.

Soffit is the horizontal panel under your roof overhang. It allows air into your attic and protects the underside of your gutters.

Together, they protect your roof structure, seal out pests and weather, and create a clean, finished look along your home’s exterior. Need fascia info? Visit our Fascia Services page →

FAQs: Soffits, Ventilation & Your Home

1. What does a soffit actually do?

Honestly, a lot of behind-the-scenes work. Quality soffit installation helps your attic breathe by pulling in fresh air at the roofline, which keeps moisture and heat from building up. They also protect the underside of your roof from pests, rain, and snow.

2. Can I get soffit in different colours?

Definitely. We do soffit installation in a variety of colours from Canadian aluminum brands like Gentek, Royal Building Solutions, and Kaycan. We’ll work with you to find a colour that blends in with your siding (and eavestroughs) or stands out with a clean trim look. We can even bring samples and help you find the perfect match.

3. What’s the difference between fascia and soffit?

The soffit is the panel underneath the overhang of your roof (all about airflow and protection). The fascia is the board that runs along the edge of your roof (and supports your gutters). Together, they seal off and protect the edge of your roof from the elements.

4. What’s a "soffit" when it comes to ceilings?

Good question. Inside the home, “soffit” usually refers to a boxed-in section of ceiling (like the space above kitchen cabinets). But on the exterior, soffits are the panels underneath your roof’s overhang. That’s what we install and upgrade.

5. Is soffit replacement a DIY job?

It can be, but it’s easy to mess up. You’re working at heights, dealing with aluminum panels, and you need to make sure airflow isn’t blocked. That will require you to have multiple people to help or many hours (or days) on your own. And if it’s not done right, you could end up with bigger problems down the road.

We recommend leaving it to us. We will custom-fit soffit, fascia, siding, and eavestroughs to your home and get it done right the first time.

6. How much does it cost to replace soffits?

The cost of soffit replacement depends on the size of your home and whether there’s any damage to the structure underneath. We’ll assess everything during your estimate and provide a clear, detailed quote with no surprises and no pressure. Just honest pricing for quality work with Canadian aluminum products.

7. How long do soffits last?

If they’re installed properly, aluminum soffits can last 30 years or more. Still, it’s a good idea to keep an eye out for signs of moisture, peeling, or poor airflow (especially after heavy storms or long winters).

8. Do soffits help prevent ice dams in winter?

Yes, they play a big part. Vented soffits bring cool air into your attic, which helps keep the roof temperature stable. That means less snowmelt refreezing at the edge and fewer ice dams forming.

Roof Ventilation That Works All Year

Good airflow is critical to a healthy home. If you walk under a roof line (with our soffit installed) and look up, you’ll notice little vents spread out at certain intervals. Those are vents for your roof.

We install vented soffit systems that allow air to enter at the roofline, working with ridge or roof vents to exhaust warm, moist air. This helps prevent mold, rot, and ice damming.

Ask us to inspect your attic ventilation during your estimate and we’ll make sure it’s working the way it should.
