    Comprehensive Commercial Roofing Solutions

    Whether you need a roofing company to retrofit your existing metal roof, repair a commercial flat roof, or perform routine inspections and maintenance, the Watertite Roofing team has got you covered. You can count on us for the following commercial and industrial flat roofing services.

    Metal Roof Retrofit Services

    Metal roofs are durable and easy to install. However, they are more susceptible to corrosion, rust, and damage associated with exposure to extreme weather. At Watertite Roofing, we help Mississauga commercial property owners upgrade their old metal roof into watertight commercial and industrial roofing systems.

    Our team prioritizes retrofit installs where possible instead of a complete roof removal and replacement. Thus, we level off an old corrugated metal roof assembly with insulation panels and then encapsulate the roof with a high-quality PVC flat roofing system. This eliminates the cost of removing and replacing the the roof structure and metal roofing panels.

    Before retrofitting your commercial flat roof, we perform a thorough inspection to assess the structural integrity of your roof structure. If the structure is sound, has efficient drainage, and matches the current industry standards, we can simply overlay a low-slope or flat roofing PVC membrane. This is a more cost-effective roofing solution compared to a complete roof replacement.

    Commercial Flat Roof Repairs

    Over time, exposure to freeze-thaw cycles, summer heat, and other harsh weather conditions weakens the flat roof’s seams, flashing, and membranes. Improper flat roof installation, poor maintenance, substandard roofing materials, and aging roofing membranes can cause drainage issues and other forms of commercial flat roof damage.

    Unlike residential roofs, commercial flat roofs cover extensive surface areas. That means a localized roofing issue, like a puncture or seam separation, can spread quickly if ignored. Even seemingly minor roof leaks can cause significant damage to your stock and disrupt your day-to-day operations. That’s why it’s recommended to schedule timely flat roof repairs.

    Contact us if you notice any of the following signs of weather damage to your commercial flat roof in Mississauga.

    • Ponding water or the formation of water pools on the roof.
    • Damp spots, water stains, mold growth, and other signs of flat roof leaks.
    • Bubbling or blistering of your commercial flat roof membrane.
    • Membrane tears, cracks, and other signs of physical deterioration.
    • Damage to the flashing.
    • An unexplained increase in your heating and cooling costs could signal improper roof insulation.
    • Loose fasteners and other signs of physical deterioration to the roofing materials.

    The Watertite Roofing team is available around the clock to address flat roofing issues on time and prevent further damage. Whether you are dealing with a minor leak or structural concerns, our team has extensive experience in flat roof inspections and efficient repairs with minimal disruption to your day-to-day business activities.

    Why are Commercial Flat Roofs common in the Mississauga Area?

    Many commercial buildings and industrial facilities in Mississauga have flat roofs, and there is a reason for this architectural choice. For the five decades we have been in business, we have serviced and installed flat roofing systems for commercial and industrial properties which enjoyed the following benefits:

    Cost-Efficiency and Durability

    Unlike pitched roofs, flat roofs have simpler designs that reduce the overall construction or installation costs. They are easier to maintain, which makes them a cost-effective choice for commercial roofing in Mississauga and across Ontario.

    Utilization of Available Space

    Flat roofs create extra space that can be used in different ways. For instance, you can install HVAC equipment or solar panels on your building’s flat roof. Some property owners and managers choose to repurpose the extra space into a recreational area or a rooftop garden.

    Easy Maintenance and Repairs

    Cleaning and repairing flat roofs is easier than pitched roofs. A roof maintenance contractor can quickly and safely access a flat roof for routine inspections and maintenance tasks. This can save you money and time. Easy maintenance also means minimal disruptions to your operations within the building.

    Versatile Designs

    Flat roofs, especially in commercial roofing, offer versatility in terms of architectural designs. Designers and architects have the freedom to create sleek and modern roofs that are aesthetically pleasing. This level of flexibility in design is a significant feature for business property managers and owners who intend to make a bold statement with their premises’ architecture.

    It’s crucial to note that an improperly designed commercial flat roof can lead to drainage issues, leaks, and eventual structural damage. Let the Watertite Roofing team inspect your current metal roof and retrofit it carefully. We also provide repairs and maintenance services for existing industrial and commercial roofing systems.

    Every Commercial Roofing Project in Mississauga Is Unique

    No two commercial flat roofing projects in Mississauga are exactly alike. Each commercial flat roof presents its own set of conditions, challenges, and opportunities, which is why a thorough, on-site assessment is a critical first step in delivering reliable and cost-effective roofing solutions. Our professional roofing services begin with a detailed site visit conducted by our experienced staff to ensure every aspect of the roofing project is fully understood before recommendations or pricing are provided.

    During our site visit, we evaluate key factors that directly influence the scope, system selection, and overall cost of flat roofing services. These include the size and layout of the roof, the condition of existing roofing materials, insulation levels, drainage performance, and any signs of ponding water, weather damage, or underlying structural concerns. We also assess access points, safety requirements, and how work can be completed with minimal disruption to ongoing business operations for Mississauga businesses.

    Additional considerations such as the need for roof repair versus full roof installation, compatibility with existing roofing systems, requirements for energy efficient upgrades, efficient drainage, or future additions like solar panels can all impact pricing. The complexity of the building, the type of commercial property or industrial property, and compliance with current industry standards are also carefully reviewed. These variables help determine whether a cost effective repair, restoration, or replacement approach will deliver the best long term performance and reliable performance.

    By conducting comprehensive inspections and clearly explaining our findings, we provide property owners with transparent recommendations and competitive pricing they can trust. This site-specific approach ensures each commercial flat roofing Mississauga project receives a customized solution designed to protect valuable assets, avoid costly repairs, and deliver a well maintained roof supported by dependable service and ongoing maintenance programs.

    If you are planning your next roofing project in the Mississauga area, our team is ready to assess your roofing needs and provide a detailed, no-obligation free quote following a professional on-site evaluation.

    FAQ

    The lifespan of most commercial flat roofs depends on the quality of the roofing membrane, professional installation, proper maintenance, and other factors. With proper installation and regular maintenance, the lifespan of a commercial flat roof can be significantly extended.
    Flat roofing systems are more cost-effective for large properties than pitched roofs. They are easier to install on warehouses and industrial facilities and allow for more efficient use of space and maintenance.
    It is recommended to schedule a professional inspection for your low-slope or flat roof system in the spring or fall. Buildings in Mississauga are exposed to harsh weather conditions, so regular inspections help identify issues early and extend the roof’s lifespan.
    The duration of commercial flat roof repairs depends on the condition of the roof. Minor repairs may take a few hours or a single day, while more complex repairs can take several days to complete.

      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.
