What our customers are saying

  • There’s a reason the Watertite team consistently receives glowing reviews & is a highly rated Better Business Bureau member - such standing can only be earned - by consistently delivering a high-quality service & customer experience. To start, Zak prepared a detailed quote that included photos & clearly outlined what needed to be done & why. Thereafter, Zak dispatched a highly skilled, professional team to make the much-needed repairs. Thank you Zak & team - you are a credit to your profession! In an industry fraught with unscrupulous characters, it’s a comfort knowing the Watertite team’s business model subscribes to such old-fashioned values as honesty, integrity, quality, & doing what they committed to do. Better Business Bureau membership is a key differentiator in an industry that lacks governance, oversight & consumer protection enforcement.

  • 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
  • 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.

  • 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!

  • As a custom home builder and renovator we work on many unique projects that require unique products and solutions. We only work with contractors that can provide the level of professionalism, service, and product quality that we demand of ourselves for our clientele. Watertite Roofing is one of those contractors who sets the bar higher for others. Their response time, organization of operations, and delivery on service is rarely paralleled. And they install a durable, well warrantied product that takes a load off our minds. We wouldn't use anyone else.

  • 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.

  • In 2018 the team at Watertite installed a new flat roof on our building. Being that it was fairly new product and procedures to us we were a bit apprehensive at first. However, Zak and the team were great to deal with in terms of explaining the new product and installation procedures and it really eased our mind during the decision making process. During installation the team couldn't have been better. Quick, clean and efficient, very knowledgeable and upon completion they took the time to explain the do's and don'ts as well as general maintenance tips for us to follow. This past week during the excessive snow storms we've had in our area we had some water dripping into our office and showroom. Zak had a team member over the next business day to have a look, at no charge. He did the best he could to clear the water and ice from a frozen eavestrough and downspout that was causing water to travel behind siding and under the membrane. We are very grateful for them to have come out so quickly and not even charge us even though the leak wasn't even from their roof installation! We have another project in the works for the spring time and we will definitely be going with the team at Watertite again!

  • 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.

  • 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.

  • 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.

  • As the VP on the board of directors for our co-op apartment building in Hamilton for only the last 8 years, I was not involved in the initial decision to purchase a replacement solution for our, now, 60 year old building and therefore cannot comment on time lines involved. However, a few years ago, we felt the need to make sure it was working as it should and had a Watertite manager come to do an appropriate inspection, which resulted in his assurance that all was as it should be, which also gave me the opportunity to get a deeper understanding and appreciation of the Duro-Last product installed by Watertite. Though it is ill advised to walk around the roof in spiked track shoes, there is a fair amount of traffic as a result of regular, seasonal maintenance of our 4 roof drains by service personnel and yet the roof still continues to show no sign of aging. There is an apartment across the street of similar size and vintage that seems to almost annually require people to come and re-apply tar paper and heated tar. By contrast our roof has needed absolutely no maintenance in the 10 years since its installation and we still have another five years on our warranty. I understand this material has a number of installations in excess of 30 years. My understanding of the initial advantages of our purchase decision relate to: - the comparative speed and efficiency of installation due to its pre-engineering and construction in the consistency of a factory environment, -the fact the membrane could be installed over top of existing infrastructure without expensive replacement of valuable materials that continued to serve the building, -that it is safely installed without the use of open flame tools and finally, -as opposed to (sun) heat-absorbing tar paper based installations, the Duro-Last is made of a reflective material which contributes directly to the diminished need for air conditioning compensation. I have zero problems recommending the Watertite's Duro-Last roof replacement or for new building installation.

  • We hired Watertite Roofing to repair a leaking flat overhang on the front of our house that had been poorly done by another roofing company about 10 years earlier. Rot had set in and owner Zak Keyes had the solution for a permanent fix. Lead hand Jon took over from there and skillfully directed his crew to undo all the damage, working tirelessly in cold weather to give us a house that looks great and the knowledge that the problems are fixed for good. We highly recommend Watertite Roofing for flat roof construction and repair. Leanne and Pierre – Hamilton Ontario

  • 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!
