What our customers are saying

  • Zak at Watertite was fantastic! Called him up to get a quote and was very happy with the responsiveness. The work was completed as promised and in a very professional. Would definitely recommend them for any roofing needs.

  • Always a pleasure working with Waterside Roofing from Dunnville, Ontario. Watertite is very professional at their workmanship and I will continue to have them complete multiple jobs in the future.
    Rodney Hipwell
  • Well, we started by looking for an award-winning roofing material that could withstand the harsh Canadian weather. Then we discover Dura-Last – the most advanced vinyl roofing material ever developed. In so doing we also discovered an award winning flat roofing installer, even recommended by Dura-Last themselves. Turns out Watertite Roofing is the best flat roofing installer in Canada, serving right here in Southern Ontario. Went to their office, and I couldn't believe the number of awards that they have received. Hall walls full of awards. Nobody gets that many awards unless you're real good. So we not only get an Award winning product to protect our commercial investment, but we get the award-winning installers to boot. Don't gamble with your commercial properties - Watertite Roofing; the flat roofing specialists.

  • Watertite did an amazing job with our rooftop terrace installation, very professional and built to last many years. I would recommend them to anyone looking for a solution that is long lasting and low maintenance. Amazing job!
    Glenn Edwards
  • Zac and his team have been incredible from our first contact. They were the most reasonably priced of 4 quotes, got the job done quickly when they said they would, have promptly responded to any queries and have came back to support installation of ventwork during renovations. The new roof, trim and eaves troughs look great and we're very happy with the service.
    Amanda Harry
  • 5 Stars for commercial flat roofing in Haldimand and Niagara
    Myron Myslowka
  • We did our due diligence on roofers when we needed a complete new 15,000 square foot flat roof. All signs were positive for Watertite and they did not disappoint us, they did a great job. Zack was our main contact and he kept us informed throughout the project and always returned our calls in a timely fashion. Well done Watertite team! Larry Fontaine, president of Fontaine Transport Inc.
    Barb Fontaine
  • Watertite Roofing is very professional. The quality of their work is outstanding. I would not hesitate to use the them again.
    Greg Olsen
  • Great experience - everything about their roof system was well explained, price was very competitive and the work was done on schedule with a great crew - what more could you ask for?
    M. B.
  • After doing a lot of research on possible solutions for renewing an existing 35yr old low pitch corrugated metal roof on a pre-eng industrial building; a membrane overlay system was chosen as the most effective from a performance, cost and warranty standpoint. After engaging 3 local firms for proposals, it quickly became apparent that Watertite was by far the best solution to meet our needs. Their rep (Zak) was very easy to work with, maintained great communications, and was very professional/responsive to any questions or communications I had. Through the whole process (survey, quotation, project coordination/execution, and wrap-up), Watertite and their personnel were top notch with little inconvenience to the tenant. Definitely would not hesitate to highly recommend Watertite and the Duro-last membrane system.
    Dave Allan
  • The company is a family business, however they have plenty of other people to take care of your needs. Their estimate is done by Google earth and their representatives are very professional and helpful. The system they represent has an excellent 20 year warranty and provides a beautiful looking end result. Using this product is definitely a money saver when doing a flat tar and gravel roof replacement. I highly recommend them.
    Ulrich
  • Great responsiveness, good value and no hidden costs. Would not hesitate to recommend this company to anyone needing roof work. Chris Elgar of C Elgar Holdings Limited.

  • Thank you Ibrahim, We really appreciate your Google rating us five stars. Can you share a few words about your experience please as it would be helpful for fellow Googlers. Thank you kindly from Management and Staff
    Ibrahim Jame Mosque
  • The Optimist Club of Dunnville has worked with Watertite over the years. Recently, we contracted them to install a Duro-Last overlay roof system on the flat roof over our kitchen and back storage area. We were very pleased with the job. They noted a minor concern on a roof on which they were not working and repaired it at no extra charge. The team from - the quote, to the installation, to the office payment was friendly and professional. Installation of this durable, well-warrantied roofing allows us to focus our time and energy on our mission with the youth rather than worrying about leaking roof. Kudos to the Watertite team!
