Roof ​Repair for Flat & Low-Slope Roofing

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?

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

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 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.

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.

It's great to see local businesses such as Watertite Roofing - Specialists in Flat Roofing actively participating and helping the local community. Thank-you so much for your support this year at our BMX race track. We all do it for the kids!

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.

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!

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.

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.

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.

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.
