About typical — the typical roofer in Quebec sits at 2.9%. A higher share is a reason to read the critical reviews below, not a verdict.

The critical reviews

The one and two-star reviews, first. These are what a star average hides, and they are the reason this page exists.

The only one or two-star review we hold for Groupe DBL.

    The roof, installed in 2020, has leaked regularly every year since, causing damage to the building. DBL has never properly fixed the problem. If I had to do it again, I would hire a more reliable company that can install a roof correctly so that it doesn't leak inside.

    Reply from the business

    Hello, I would like to remind you that the contract signed in 2020 still has an outstanding balance of $6,845.25. Despite our efforts with Alliance Credit in 2021, the bailiff has never been able to locate you. Unfortunately, the application of the labor warranty is conditional upon full payment for the work. Therefore, we propose the following steps: Full payment of the outstanding balance; Inspection of the roof by our team; Analysis of the situation to determine if the problem is covered by the warranty. If the issue is covered by the warranty, the necessary repairs will be carried out. Otherwise, an estimate for the work will be provided. We remain available to plan the next steps upon receipt of payment. Sincerely,

    Groupe DBL Inc. has a competent, meticulous, and friendly team. The workers are dedicated to their work. My house's roof was covered with a very high-quality Soprema membrane.

    Hello Ms. Filion, thank you so much for your feedback. It was a pleasure working with you on your project. Thank you.

  • 5 out of 5Penelope Daignaulta year ago

    I wholeheartedly recommend this company, with whom I've been working for two years on interior renovations in my home (bathrooms, room reconfiguration). The team led by Maxim is incredibly professional, offers excellent advice, is super friendly (Rémi and Paul-Émilie are my favorites), and trustworthy. The work is always completed on schedule—even when deadlines are extremely tight! (Thank you!)—and at the very competitive price agreed upon. I've referred DBL to friends and will continue to do so. They are my number one choice for construction contractors! Thank you, DBL Group! :)

Where this page comes from

Every figure above is Google’s, captured on 24 September 2026. The star average and the 121 ratings behind it are counted by Google across all of its reviews. The review text on this page is a sample — we hold 121, of which 93 have any text — and it is not everything Google shows.

Roof Warden does not verify licenses, bonds, insurance or workers’ compensation cover, and nothing on this page should be read as though we had. Confirm those directly with the contractor and with your state or provincial licensing body before you hire anyone.
