    Top Commercial Flat Roofing Solutions in the Burlington Area

    Watertite Roofing is a full-service, BBB-accredited commercial roofing contractor specializing in roof installations, restoration, and replacements. We aim to ensure your commercial building or industrial facility has an efficient roof that can protect it from water-related damage. The roof should protect the assets, business operations, tenants, or staff within the building.

    Regardless of the current condition of your commercial roof, you can contact us for the following roofing services:

    Commercial Flat Roof Repairs

    Roof damage can disrupt your business operation and lead to costly future repairs. When you notice the earliest signs of flat roofing issues, we recommend taking immediate action. Contact Watertite Roofing right away for timely roof repairs. Here are the warning signs that your commercial building’s roof needs repairs:

    • Damp spots or water stains on walls and ceilings indicate roof leaks
    • Visible blisters or bubbles on the roofing membrane suggest poor insulation or trapped moisture
    • Bent, cracked, or missing flashing around the vents, roof edges, and skylights
    • An explained and sudden increase in energy bills may suggest a decrease in your roof’s energy efficiency
    • Water pooling on the roof long after rainfall may indicate drainage problems

    Here at Watertite, our team of professional roofers performs thorough flat roof inspections to determine the nature and extent of your flat roof deterioration. Whether you’re dealing with roof leaks, punctured membranes, or a failing roof drainage system, our experienced team is available even for emergency repairs.

    Commercial Flat Roof Retrofit

    Flat roof assemblies and low-slope metal roofs are renowned for their durability, but over time, they can become corroded, start to leak, and become less efficient in terms of energy usage. When it’s time for a roof replacement, a costly project including the removal of your old roof and roofing insulation, and their full replacement, isn’t always necessary. At Watertite Roofing, we provide a thorough inspection of your roof and determine whether a full roof removal and replament is required, or whether we can more cost-effectively encapsulate your existing roof assembly through a roof retrofit or overlay, saving significant dollars in labour and materials.

    One benefit of retrofitting instead of replacing the entire roof is that you have the opportunity to install energy-efficient and durable Duro-Last or Canada-made Goliath PVC roofing membranes at an affordable cost.

    Retrofitting works only when the underlying roof structure (deck and insulation) is in fair condition. That’s why our expert team will first inspect your roof to determine its current condition. We’ll recommend full replacement if the roof deck is severely damaged or your roof is retaining moisture within the roofing substrates.

    Commercial Flat Roof Maintenance

    Proper maintenance can help keep your flat roof energy-efficient and functional. Ideally, you should get it inspected twice a year (once in Spring and again in Autumn). During the routine maintenance, we’ll clean your roof, inspect it, and identify even the seemingly minor signs of damage.

    Any issues noted during the inspection will be addressed and fixed immediately to prevent further damage to your roof. For instance, loose seams or the earliest signs of flashing problems can be fixed before they turn into costly repairs.

    In addition to routine roof inspection and maintenance, we offer seasonal roof inspections. When hailstorms, severe freeze/thaw cycles, high winds, and other forms of extreme weather occur, they can cause extensive damage.

    Our roofing professionals can inspect your roof, assess the extent of the damage, and make the necessary repairs. At Watertite Roofing, we’re a trusted partner for regular inspections and roof maintenance services.

    Why Choose Duro-Last or Goliath PVC Roofing Systems?

    Duro-Last is North America’s top manufacturer of cutting-edge materials for commercial flat roofing. Their thermoplastic, single-ply roofing membranes are custom-fabricated to meet each specific roofing requirement. This approach to flat and low-slope roofing has revolutionized the modern roofing industry.

    Here’s why Duro-Last and Canada-made Goliath PVC roofing membranes are widely chosen:

    Exceptional Roof Durability

    Duro-Last and Goliath flat roofing membranes are made of high-strength PVC (polyvinyl chloride). They can last 25 years or longer with proper maintenance. Note that the roof surface is designed to withstand punctures and damage associated with exposure to chemicals, UV rays, and fire.

    Therefore, Duro-Last and Goliath PVC roofing membranes are suitable for commercial and industrial facilities in harsh climates. Our skilled team will recommend the top-quality materials for your roof and other accessories, such as insulation, skylights, and more.

    Energy-Efficient Roofing Membrane

    Duro-Last and Goliath PVC roofing systems are designed with energy efficiency in mind. For instance, the roof surface is highly reflective to minimize heat absorption, which reduces the cost of indoor cooling during the summer.

    Here at Watertite Roofing, we recommend roofing systems that match Energy Star requirements. After all, an energy-efficient roof allows Burlington property managers and owners to save on their monthly energy costs.

    Environmentally Friendly Roofing Solution

    One aspect that makes Duro-Last an environmentally friendly roofing material is that it can be recycled. When you finally decide to replace your Duro-Last PVC membrane, it can be sent back to Duro-Last for recycling instead of disposing of it in a landfill. Work with the experienced roofers at Watertite Roofing to access the best materials for an eco-friendly roof.

    What’s the Cost of Commercial Flat Roofing in Burlington?

    The cost of commercial flat roof installation, repair, and replacement services in Burlington depends on many factors. These include the extent of the damage, the size of your roof, the cost of labour, and the overall complexity of your project. Therefore, it’s recommended to request a free quotation to get a reliable cost estimate and project timeline after the initial project assessment.

    For example, the cost of patching small cracks or fixing minor leaks is significantly lower than the cost of repairing extensive damage to the roofing membrane or flashing. Similarly, the cost of retrofitting an existing flat or low-slope roof may be considerably lower than that of replacing an entire roof structure. Here are the factors that affect the total cost of flat roofing services:

    Size of the Roof

    The roof repair or installation process for a large industrial facility is complex and requires more labour hours than a project involving a small business building. Depending on the current condition of your roof, you may need repairs, partial replacement, or complete replacement.

    Labour Cost

    The cost of labour majorly depends on your preferred roofing contractor and the prevailing labour prices. That means labour-intensive projects may cost more than minor roof repairs. Here are the estimated costs of labour for different flat roofing systems.

    Roof Type

    Pricing for flat roofing systems can vary significantly depending on the material, installation complexity, and long-term performance expectations. Single-ply systems like Duro-Last PVC roofing typically come at a premium because they are custom-fabricated, highly durable, and offer strong warranties with minimal disruption during installation. Goliath PVC roofing systems are also priced higher than basic membrane options due to their reinforced construction, superior chemical resistance, and longevity, making them a strong choice for commercial and industrial buildings. More economical systems—such as modified bitumen or basic EPDM—may offer lower upfront costs, but they often lack the lifespan, energy efficiency, and reliability of high-performance PVC roofing solutions.

      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.
