10 Best Roofing Companies in Montreal, QC (Updated 2026)

TenBestFind ranks 10 roofing companies in Montreal, QC. Each company was checked against the criteria set out under How we chose. Each entry below says why the company was picked and what to weigh before hiring. Marcus Reed last reviewed the list on October 15, 2026.

Toiture Unix, René Perron Couvreurs and Toiture Expert lead our October 2026 list of the 10 best roofing companies in Montreal, all rated 4.5 or higher on Google with at least 50 reviews. Most of the city's duplexes and triplexes have flat roofs, so six of the ten are flat-roof specialists and six publish an RBQ licence on their sites, while Eco Marco and Toitures METALAVIE cover steel roofs.

The Ranking

Our top 10 roofing companies in Montreal

Montreal roofs take a beating. Freeze and thaw cycles run from November to April, snow loads sit for weeks, and ice dams form along the eaves of older plexes in Plateau, Rosemont, Villeray and Verdun. Much of the housing stock is flat or low-slope, which is why membrane systems (elastomeric bitumen, TPO, EPDM, multilayer asphalt and gravel) show up so often in this list, and why a leak in a triplex usually involves the owner, a tenant and an insurer at once. In Quebec, a roofing contractor must hold a licence from the Régie du bâtiment du Québec (RBQ). Before you sign anything, look up the licence number on the RBQ licence search at rbq.gouv.qc.ca and confirm the company name and the subcategory match the work. Ask for the number in writing, ask who carries the workmanship warranty, and get the scope and the roofing system named on the quote. Where a company in this list publishes its RBQ number we show it on the profile, and where it does not we say so. Every company here operates from a street address inside the city of Montreal, including boroughs such as Saint-Laurent, Saint-Léonard, Rivière-des-Prairies, Lachine and NDG. Many serve Laval, the South Shore and the West Island too, but we only list firms based within the city limits.

Methodology

How we chose the best roofing companies in Montreal

We searched Google Maps for roofing contractors in Montreal on October 15, 2026 using several English and French searches, then kept companies that were operational, rated 4.5 or higher, had 50 or more Google reviews, ran a real company website and had a street address inside the city. We removed referral and lead-generation sites, renovation brokers, franchise lead funnels, general contractors, suppliers and service-area businesses with no address. The remaining companies are listed in the order they appeared in Google Maps across those searches. We read each company's website for licences, warranties and services, and used the Google rating and review count as of October 15, 2026. No company paid for a place on this list.

Hiring

How to choose a roofing company in Montreal

  1. Verify insurance and credentials

    Ask for a current certificate of insurance and confirm registration or licensing with the authority that issues it, not with the company.

  2. Ask for a written estimate

    Scope, materials, removal, disposal and who pulls the permit should all be named on the page rather than agreed on the doorstep.

  3. Compare multiple quotes

    Two or three bids on the same scope. A number far below the others usually means something has been left out of it.

  4. Understand the warranty

    Separate the manufacturer's warranty on materials from the company's own warranty on the work, and get both in writing.

  5. Ask who performs the work

    Find out whether the crew are employees or subcontractors, and who supervises them on the day.

  6. Check recent local projects

    Ask for addresses or photographs of comparable jobs finished nearby in the last year or two.

  7. Avoid high-pressure sales

    A discount that expires today, or a knock on the door after a storm, is a reason to slow down rather than sign.

  8. Get everything in writing

    Change orders, timeline and payment schedule included, before the first payment changes hands.

Questions to ask before hiring

0 of 10 asked

Red flags

  • No verifiable local business address or registration
  • Pressure to sign on the first visit
  • A demand for full payment up front
  • An offer to cover or waive your insurance deductible
  • Refusal to put warranty terms in writing
  • A quote that will not itemize scope

FAQ

Roofing companies in Montreal FAQs

How do I check a roofer's licence in Montreal?

Look the company up on the Régie du bâtiment du Québec (RBQ) licence search at rbq.gouv.qc.ca. Enter the licence number or company name and confirm that the business, its status and the work subcategory match your job. Ask the roofer for the number in writing before you sign.

How long does a flat roof last in Montreal?

It depends on the system, but companies in this list quote written warranties from 10 to 15 years on labour and longer on materials such as TPO or steel. Winter freeze and thaw is the main stress, so ask for a yearly inspection and clear drains and snow around parapets after heavy storms.

Do Montreal roofers work on duplexes and triplexes?

Yes. Flat and low-slope plex roofs are the core of the work for most companies on this list, including Toiture Unix, Toiture Expert and Clinique de la Toiture FCA. Ask which membrane system they propose, who handles tenant access and whether the quote covers drains and flashing.
