about us

Dorval Roofing is a small roofing company situated in Dorval, Québec. We service the West-Island, Châteauguay, L’Île-Perrot and its surroundings. We differ from other roofing companies in that we work closely with our customers. We offer a more personalized service and we install one job at a time. We will supply you with full colour brochures and samples to help you determine the best shingle style and colour to match your home, not necessarily your neighbourhood.

Every home should have its own identity. With Dorval Roofing, we will explain to you honestly the primary components of your roof and what work will need to be done. In today’s world, we are all so very busy, so sometimes meeting up to discuss an estimate is hard. We can go by your residence throughout the work day, measure your roof and look for key points and critical areas and prepare you with a well detailed proposal based on our expertise. Everything may be discussed over the phone as we have already seen and taken the measurements of your project!

With Dorval Roofing, you will see an experienced roofer, not a salesman! Our expertise speaks for itself and our referred customers are our sales force. We are your trusted West Island Roofers! Contact us now!

For Quality Shingled Roofs in the Dorval Area

As experienced professionals in the roofing business, we at Dorval Roofing know that the most critical aspects of your roof system involve:

  • A Solid Roof Deck
  • Ventilation
  • Proper Underlayment in Crucial Areas of the Roof
  • Shingles

These critical aspects should be selected according to the slope of your roof. Let us help you choose the roofing that has to last for the next two decades or more.

No sub-contracting

Unlike larger companies who subcontract work, we have our own trained team to carry out all the work from start to finish. We pay close attention to the crucial areas of the roof and the details. If during the course of your project, it becomes apparent that additional work is required outside our trade, we will take care of hiring the required specialists in their trade to take on the task for a worry-free project.


We hold a bond and are licensed with the Régie du bâtiment du Québec (#8307-9525-55). We carry full liability insurance and are registered with the CSST (workmans compensation board). We are also Platinum level BP Certified Roofers.


We issue a written 10 year labour transferable warranty on all our new roofs installed. Shingle manufacturer warranties vary between 25 to 40 years on a prorated scale after the initial up-front protection.
