What our customers are saying

  • 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.

  • 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.

  • 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.

  • 5 Stars for commercial flat roofing in Haldimand and Niagara

  • 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

  • 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
  • Our church (Port Colborne BIC Church Port Colborne Ontario) contracted Watertite Roofing to install new roofing on our flatroof here at the church. We are so very pleased with the job... well done...professional...tidy...exceptional workmanship...thorough...and wonderful to work with from beginning to completion. Five stars for a job well done.

  • 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.

  • Watertite Roofing is very professional. The quality of their work is outstanding. I would not hesitate to use the them again.
    Greg Olsen
  • I have full confidence in recommending this company to anyone. I have used Watertite on three occasions (three different buildings). They were professional, clean and their pricing was better than the competitors. Completely satisfied with the service and finished product.
    Stephane Marchand
  • 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!
    Brenda Zynomirski
  • 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.
  • We have used Watertite Roofing on several occasions and have been extremely happy with their service. They have come to our rescue many, many times always swiftly and professionally. It's incredibly hard finding a great roofing company. I'm pleased to say that we've found them and look forward to doing business with them for many years to come.

  • We purchased a building requiring a new flatroof. Didn't take to long to figure out who I was going to work with. Thru multiple business owners in the area and talking with some friends in real estate, the same name kept coming up. I gave Zach, owner, a call and booked a time to take a peak. He arrived ontime, prepared and presentable. He knew his product well and came up onto the roof to explain the process. After measurement and finalizing the details we decided to proceed with a roof replacement. A quotation was sent back within 2 days with pictures of the existing roof, new roof design and the payment schedule from start to completion. His crew that did the roof were very respectable of my property. There was no garbage left behind and the end product turned out great. Clearly, I'd be happy to do business with Watertite again. I could have done the contract on a handshake. Zacks words were few but what got promised happened and his communication was clear. I would have zero reservations in passing their name forward. Thanks for helping me out. Great company.
