    Whether you need new roof installation, repairs, or replacement, you can count on our team for a custom, energy-efficient, and durable flat roof. At every phase of your project, we bring the insight and flexibility needed to deliver a high-performance roof for your building.

That’s why our certified installers are at the center of our company’s success. These skilled flat roofing professionals are chosen for their decades of experience and specialized flat roofing knowledge that ensures each project is done right the first time.

    Whether you need a new flat roof for a complex industrial facility or a high-performance membrane for a custom-built home, our roofers have the training and foresight to build lasting roofs.

We also invest in modern tools and technologies that allow our team of flat roofing professionals to complete each commercial or residential roof installation successfully.

    Full-Service Commercial Flat Roofing Company

    When you choose Watertite Roofing for flat roofing services in Niagara Falls, you’re partnering with a team of the industry’s leading experts who prioritize quality, affordability, and outstanding craftsmanship. What sets us apart from other roofing contractors is our commitment to customer satisfaction. You can count on us for the following services.

    New Flat Roof Installation

    Successful flat roof installation requires careful planning, high-quality materials, and skilled labour. That’s why you need a team of trained, certified, and highly experienced flat roof professionals to handle every phase of your flat roofing project.

    Every piece of waterproofing membrane, seams, and flashing plays a key role in the performance and longevity of your flat roof. At Watertite Roofing, we pay attention to the structural integrity of the underlying structure to ensure your roof is properly installed. We also install reflective roofing systems that do not absorb the sun’s heat, providing greater roof system longevity and building energy savings.

    Flat Roof Maintenance

    Regular inspections and timely repairs are key to ensuring your flat roof lasts decades. In addition to removing debris and shrubs from your roof’s surface, each type of flat roofing membrane has maintenance requirements.

    We often recommend Goliath PVC roofing due to its durability, fire-resistance, and ability to withstand constant exposure to strong winds, hailstorms, and other harsh weather elements. It also requires less maintenance and is simple to assess and maintain, as it does not require a stone or gravel covering.

    Routine inspections help identify leaks, ponding water, and other signs of improper drainage. We also pay attention to cracking, blistering, membrane shrinkage, and flashing issues. With our inspections and flat roof repair services, you can quickly address such problems before they cause extensive water damage to your building.

    Failing to address various flat and low-slope roof issues early enough may necessitate costly repairs and shorten your roof’s lifespan.

    Flat Roof Replacement Services

    Like pitched roofs, a flat roof has a specific lifespan. While this roofing option is durable, general wear and tear, weather elements, and water damage can weaken your roof. With proper maintenance, your roof may last decades. However, you’ll need to replace it at some point.

    Here are the signs your building’s flat roof needs to be replaced.

    • You’re constantly patching up leaks.
    • Significant splits, cracks, blistering, and other visible signs of damage.
    • Water stains, especially in your property’s ceiling, may be an indication that pooling water is seeping beyond the second layer of your roof.
    • An unexplained increase in energy bills could mean that conditioned indoor air is escaping through weak spots or cracks on your roof.
    • Your roof was installed more than 20 years ago.

    The key to determining whether flat roof repair or replacement is required is to get an honest assessment completed by one of our trusted flat roofing professionals. We’ll assess the extent of leaks, cracks, and other types of damage and provide unbiased advice and a free report containing photos from your roof and explanations.

    We’ll help you compare the cost of repairs and the benefits of an entire flat roof replacement. This will make it easier for you to make informed decisions related to your business property’s roof.

    We Excel in Flat Roof Installations, Repairs, and Replacements

    At Watertite, we understand that if you plan to install a flat roof on a new construction project, you require different services from those of a property owner who needs routine roof inspections and maintenance. That’s why we follow a well-thought-out process that ensures each client gets customized services that match their roofing needs. Here’s what to expect when you choose our roofing services for commercial properties.

    Step 1: Initial Consultation and Building Assessment

    The journey to install, repair or replace a high-performance flat roof begins with a free consultation. Our industry-leading roofing experts will listen to your roofing needs, respond to your concerns, and schedule an on-site roof assessment.

    During the roof inspection process, our experts will pay attention to the current condition of your roof, identify any underlying issues, and determine the suitability of repairs or replacement. The information gathered during this assessment guides the roofing solution we recommend and implement.

    Step 2: Roof Design and Planning

    Our team of roofing professionals, supported by architects and engineers, will work closely with you to design a detailed flat roof installation, repair or replacement plan. We often recommend the Canadian-made Goliath PVC single-ply roofing system by Canadian General Tower, and we’ll help source the materials from Ontario’s top brands.

    In addition, we’ll assess and upgrade your property’s drainage system to ensure compliance with industry standards and local building codes. The planning phase lays the foundation for your entire project and the long-term success of your roof.

    Step 3: Implementation & Installation

    Goliath PVC single-ply roofing is versatile and allows for different installation options. The retrofit or overlay installation method is ideal for buildings where the roof substrate is structurally strong and dry. Our installers secure the Goliath membrane over the existing roof. Retrofitting saves significant financial resources in terms of labour and material costs. We complete such installations within a short period to minimize disruptions to your business operations.

    Suppose your property’s roof substrate is saturated with water or has suffered extensive damage. In that case, we recommend complete roof replacement. This involves removing the existing insulation and roofing material before we install the Goliath roofing option. Remember, installing PVC roofing membrane on a damaged area will only lead to further deterioration of your roof and structural damage to your property.

    Our team will complete each task, from the initial site preparation to insulation, flashing, edge detail, and waterproof membrane installation. At Watertite Roofing, we often recommend polyvinyl chloride (PVC) single-ply membranes from Canadian General Tower’s Goliath Roofing Systems. Other materials used in flat roof construction include EPDM (ethylene propylene diene monomer), modified bitumen, built-up roofing systems (BUR), and TPO (thermoplastic polyolefin).

    Step 4: Final Inspection

    Once our team completes the installation, repair, or replacement of a flat roof, we’ll inspect the entire roof to ensure every task is completed to the highest safety and quality standards. We’ll check for efficient drainage, flashing, and secure seams. Remember, we provide a comprehensive warranty for each new flat roof we install, repair or replace.

    What’s the Cost of Commercial Flat Roof Services in Niagara Falls?

    As mentioned earlier, we specialize in installing Canadian-made Goliath PVC roofs. The cost of installing a Goliath PVC membrane to cover an existing flat roof ranges between $7 and $12 per square foot on average. Metal roof retrofitting (installing a single-ply membrane on an existing metal roof) costs between $8 and $14 per square foot on average. The cost of an entire flat roof replacement will depend on the scope of your project and other factors.

    Average Cost of Flat Roof Replacement

    Here is the cost breakdown for other flat roof repair services for business properties in Niagara Falls.

    Flat roofing material Average Replacement cost per square foot
    EPDM (Ethylene propylene diene monomer) $4 to $12
    TPO (Thermoplastic polyolefin) $5 to $14
    PVC (Polyvinyl chloride) $6 to $13
    Modified bitumen $8 to $14
    Asphalt & gravel built-up-roofing (BUR) $10 to $20

    For commercial and industrial property owners, we recommend requesting a free estimate. We’ll conduct an on-site roof assessment to determine the scope of your project, required roofing materials, and labour hours. The quote will provide detailed information about the estimated cost and project timeline. It will empower you to make an informed choice to ensure lasting protection for your building.

    Benefits of a Commercial Flat Roof

    Flat roofs are the most preferred option in many commercial properties in Niagara Falls. Here are the benefits of installing a flat roof.

    Extra Usable Space

    Flat roofs provide valuable exterior space that pitched roofs simply can’t offer. Commercial property owners can transform this extra space in different ways. For instance, they can install solar panels, HVAC systems, or even create rooftop gardens and lounges.

    Our team will build your roof with these possibilities in mind. This added functionality enhances the usability of your property and can increase its market value.

    Flat Roofs are Easy to Access

    Flat roofs are easy and safe to access. Our team can reach the surface quickly for routine inspections, cleaning, and repairs. This ease of access allows us to perform work more efficiently and with minimal disruption to your business operations.

    Flat Roofs are Safer to Work on

    Compared to steep-sloped or pitched roofs, flat roofs are safer to navigate. Our roofing professionals benefit from better footing and maneuverability, which reduces safety risks and helps complete projects faster. This allows property owners to manage emergency or routine roof maintenance with less hassle and lower safety concerns.

    Install, Repair, and Replace Flat Roof System

    At Watertite Roofing, we aim to help commercial property owners enhance their buildings’ energy efficiency, functionality, and longevity through cost-effective flat roof repairs, installations, and maintenance.

    Whether you need our help to keep your roof clean or replace a failing roof system, you can rely on our expertise and commitment to customer satisfaction. Request a free quote today.

      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.
