What our customers are saying

  • I had the opportunity to work with Watertite in 2008, they educated me on their product along with the installation process. The job was completed in a diligent and timely manner and the material is a superior technologically advanced product. Most recently, I had an ice issue this past December where Watertite came out to my building to tackle an ice issue. Upon completion, I was shocked to hear from Zak that there was NO charge for the time spent. There are a very few out there that exercise honest ethical business practice... THANK YOU

  • 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!

  • 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.

  • During a heavy rain event, the roof leaked and one of the tenant was concerned about the leak. I called Watertite Roofing and they were on the roof to patch the leak by end of the same day. In the meantime, they did an assessment of the roof and provided a quotation within days for the replacement of the roof. Once the quotation was approved, Watertite Roofing promptly began to replace the roof the following day. The foreman on site for Watertite Roofing was considerate of intrusion to the businesses and their clients. The site foreman was approachable and made changes requested by the landlord. The work was completed in four days and before the next rainfall. Communication with the head office was always pleasant and frequent updates were provided every several days of work progress by the Operations Manager/Estimator. I was pleased with the quick response and the professional manner in which the work was completed ahead of time.
