    Our Comprehensive Commercial Flat Roof Services

    The Watertite Roofing team has been serving business and industrial property owners in Ontario for close to five decades. From Hamilton and Toronto to Burlington, Mississauga, and the entire Niagara region, we provide quality commercial and industrial roofing services tailored to the unique roofing needs of business buildings.

    Low-Slope & Flat Roofing System Retrofit Services

    The Watertite Roofing team recommends repairing your commercial flat roof if you are dealing with limited damage. Patching up minor leaks and cracks can prevent future costly repairs and extend the lifespan of your roof without the high cost of full roof replacement.

    However, low-slope and flat roof repairs are not enough to fix roof damage if your existing roof is deteriorating due to age and extensive water or moisture infiltration. Before we recommend a complete flat roof replacement, we inspect the existing roof membrane and the structural integrity of the roof deck.

    If the roof deck is significantly damaged, or the roofing insulation is saturated with water, we may recommend replacing the entire roof. However, if the roof deck and insulation is still in good condition, we recommend retrofitting a quality PVC roof membrane. That means you will get a new flat roof without incurring the cost associated with a complete flat roof removal & replacement. Before you schedule flat roof construction, talk to our team to find out if a retrofit is possible.

    Commercial Roof Repair Services

    Flat roofing systems on industrial, commercial, and institutional buildings across Port Colborne are usually exposed to intense summer heat, UV radiation, freeze-thaw cycles, strong winds, and other harsh weather conditions. Over time, your once trusted flat roof system may begin to blister, crack, or show other signs of physical deterioration.

    Seemingly minor roofing issues like leaks can disrupt business operations and cause damage to items or equipment in your building. Other forms of damage, such as extensive cracking and membrane damage, can affect your roof’s ability to protect your building. At Watertite Roofing, we recommend getting your roof inspected and repaired by a professional once you notice any of the following signs of flat roof damage.

    • Damp spots, mold growth, and water stains on ceilings and walls.
    • Bubbling and blistering on the flat roof membrane.
    • Noticeable tears and cracks on the surface of your flat roof.
    • Flashing is separated from the roof’s corners and edges.
    • Presence of moss, algae or lichen on your roof.
    • Deteriorated topcoat due to exposure to high winds and UV rays.
    • Sudden and unexplained increase in your energy bills.
    • Loosened fasteners and other signs of visible roof material damage.

    At Watertite Roofing, we inspect commercial and industrial flat roofs, identify any possible damage, and fix it. Our experienced roofing professionals specialize in inspecting and repairing flat roofs to ensure proper drainage. Therefore, Port Colborne commercial and industrial property owners can have peace of mind knowing that professional help is a single phone call away.

    Commercial Flat Roof Maintenance Services

    After five decades as professional flat and low-slope roofing, we understand the unique maintenance requirements of flat roofing systems for commercial and industrial properties in Port Colborne. We recommend scheduling your flat roof maintenance at least twice a year (in the fall and in the spring). Note that regular maintenance can extend the lifespan of your roofing membrane and delay the need for a new roof.

    Our team will perform the necessary maintenance to ensure your building’s roof is in perfect condition. During the roof maintenance process, if we notice any form of damage, we will do repairs that work within your budget and unique project timeline.

    At Watertite Roofing, we recommend scheduling professional roof inspections and maintenance at the same time. During maintenance, we clean your flat roof and address any surface-level issues related to the flashing, roofing membrane, and anchors. We ensure that your flat roof is clean and strong enough to withstand exposure to harsh weather.

    Professional roof inspections, on the other hand, go a step further. Our experienced roofers provide a thorough assessment of every part of your roof. For instance, we assess the roofing membrane, the roof’s drainage system, insulation, the underlying roof structure, and more. This detailed approach allows us to make reliable recommendations related to repairs or new roof installations.

    What are the Benefits of Metal Roof Retrofits?

    If you have an existing low-slope metal roof, our team can overlay a high-quality and durable PVC membrane over the existing roof structure. This innovative approach eliminates the need for removing your old metal roof and exposing the building to the elements. At Watertite Roofing, we recommend retrofitting due to the following benefits.

    Cost-Effective Roofing Solution

    During retrofitting, our team uses top-quality PVC membranes from brands like Duro-Last and overlays them on the existing roof structure. Thus, our roof retrofit process reduces the necessary materials and labour and lowers the cost of disposing of the old roofing materials. For Business building owners and managers, retrofitting is more cost-effective than a complete flat roof removal & replacement.

    Limited Disruptions to Your Operations

    A complete flat roof replacement (tearing it down and rebuilding from scratch) can be disruptive and time-consuming for businesses. Retrofitting reduces downtime because it takes less time than a complete roof replacement, and your business can remain operational throughout the retrofit. That means you will get a new roof with minimal downtime. Furthermore, this approach does not require your building be opened up to the elements during construction of your commercial roofing system.

    Higher Energy Efficiency

    Energy savings are a priority for many business property owners in Port Colborne, and that is what our retrofit roofing services deliver. A carefully retrofitted PVC roofing system improves insulation and regulates indoor temperature. Depending on the reflectivity of the newly installed roofing system, it can reduce cooling costs during Port Colborne’s hot summers.

    Every Flat Roofing Project in Port Colborne Is Unique

    Every flat roofing project in Port Colborne, ON presents its own set of variables, which is why a detailed on-site evaluation is essential before any work begins. From commercial buildings to industrial properties, no two commercial flat roofs are the same. Our professional roofing services start with a thorough site visit conducted by our experienced staff to fully assess the condition, layout, and requirements of each roofing project.

    During our inspection, we review factors that directly influence system selection, scope of work, and pricing. These include the overall size and configuration of the roof, existing roofing materials, insulation performance, and drainage efficiency. We also look for signs of ponding water, weather damage, leaks, and potential structural concerns that could impact the longevity and reliable performance of the roofing system. Access limitations, safety requirements, and scheduling considerations are evaluated to ensure the work can be completed in a timely fashion with minimal disruption to daily operations.

    Pricing for flat roofing services in Port Colborne can also be affected by whether the project involves roof repair or full roof installation, the complexity of the building, and the condition of existing roofing systems. Additional considerations such as energy efficient upgrades, improved efficient drainage, compatibility with future installations like solar panels, and long-term maintenance programs are reviewed to help prevent costly repairs and extend the life of the roof.

    By completing detailed inspections and providing clear recommendations, we deliver cost effective, customized roofing solutions backed by dependable service and competitive pricing. Our site-specific approach ensures property owners in Port Colborne receive solutions designed to protect their valuable assets, meet industry standards, and support long-term performance.

    If you are planning your next roofing project in Port Colborne, our team is ready to assess your roofing needs and provide a professional site visit and free quote to get started.

      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

      In February this year, we had a serious flooding problem at our house coming from an outside flat roof deck and probable freezing / ice damage. As part of researching our options, we learned that identifying and fixing flat roof issues can be very complicated, expensive and problematic for insurance coverage. While WaterTite Roofing was not involved in the original installation of our flat deck, Zachary came to our house the day after we contacted him and provided us with a detailed assessment of the problem, a solution and the cost. While we ended up using a different roofing company, mostly due to insurance complications, we could not have been more pleased or impressed by the professionalism of Zachary and we make no hesitation in suggesting you consult WaterTite / Zachary if you have an issue with a flat roof.

      Don Davidson

      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

      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

      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.

      Chris Elgar

      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.

      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

      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

      Zappa Zappa

      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

      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.

      D. B.

      The crew from Watertite Roofing did and amazing job. They were professional and friendly and worked hard to get the job done. Quality of work was fantastic. It even cost less than originally quoted and appreciated the honesty. Highly recommend this company.

      J. W.

      this team was excellent! they repaired our roof (a former elementary school) and did the work on time and within budget. The crew were friendly, professional and cleaned up all during the project work. We have asked them to quote us a second building and look forward to having this repaired. They are the experts in flat roofs. Great work Watertight!

      Joanna Mataya

      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.

      David Tucker

      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!

      Steve Yendt

      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!

      Protecting a Local McDonald’s: A Flat Roofing Success Story

      When it comes to flat roofing, many people think it’s just about the surface. However, a well-installed flat roof requires a more comprehensive approach – one that considers the entire roof envelope. This includes all the interconnected components that work together to protect the building from the elements, such as weather, moisture, and temperature fluctuations. Recently, we had the opportunity to apply this expertise to a well-known local business – a McDonald’s restaurant.
