5 Best Roofing Contractors in Toronto (2026)

Independently ranked by our review of ratings, reviews and reputation · How we chose

By Brad Smith, Home Services Expert · ✓ Data verified August 2026 · 8 min read

A roof problem in Toronto rarely waits for convenient weather. Between the roofing contractors on this page, customers have logged nearly 900 reviews, with Alpine Roofing alone carrying 600 of them and running since 1974, so the field splits between one long-established name and several newer crews building fast, spotless track records.

Short answer: Alpine Roofing is the safe default, rated 4.5 stars across 600 reviews and operating in Toronto since 1974 with a no-deposit policy that reviewers repeatedly praise. For flat roofs specifically, Advanced Flat Roof Systems (5.0, 52 reviews) and its 10-year warranty stand out. Three Bro Squirrels Roofing (4.9, 144 reviews) is the pick for skylights and emergency leak repair.

Watch: 5 Best Roofing Contractors in Toronto (2026)

How we score

Rating is the live Google average for each contractor. Review volume measures how many customers have actually left a review, ranked against the others on this page. Confidence blends rating with volume, so a perfect score built on 50 reviews counts for less than a strong score built on 600. Recency checks how many reviews are still coming in. No business can pay to change these numbers.

How much does a roof cost in Toronto? (2026)

None of these contractors publish flat pricing online, and cost depends heavily on roof size, material (shingle, flat membrane, cedar or metal), and whether it’s a full tear-off or repair, so get a written, itemized quote before committing.

Serving all of Toronto

These contractors cover downtown Toronto, East York, North York, Etobicoke and reach into Mississauga and Hamilton, so if you’re searching for a roofing contractor near me in Toronto, most of these crews already work in your neighborhood.

What to ask before you hire a roofing contractor

Is a deposit required, or is payment only due on completion?
What warranty comes with the materials and the labor?
Are you licensed and insured, and can you provide proof?
How long will the job take, and what happens if weather delays it?
Will you provide before-and-after photos of the completed work?

Frequently asked questions

Are these rankings paid?

No. Rankings come from public Google data. A business can pay to be a Featured Partner (badge + top placement), but that never changes another business’s score or position.

How did you choose these roofing contractors?

We compared real Google ratings and review counts for roofing contractors across Toronto, weighing consistency of feedback over time.

How often is this updated?

This page was last verified in August 2026 and is refreshed periodically as ratings and reviews change.

Do any of these contractors specialize in flat roofs?

Yes, Advanced Flat Roof Systems focuses exclusively on flat roofing and backs its work with a 10-year warranty.

What should I do about an emergency roof leak in Toronto?

Several contractors here, including Three Bro Squirrels Roofing, responded to urgent leak calls the same day, so start with a phone call describing the situation.

The bottom line

Alpine Roofing is the safest default given its decades of history and no-deposit policy, but for a flat roof specifically, get a quote from Advanced Flat Roof Systems before you decide.
