    The Best Commercial Roofing Services in Grimsby

    Here are the commercial flat roofing services that we provide in Gimsby, throughout the Niagara Peninsula, and across Ontario.

    Metal Roof Retrofit Services

    The Watertite Roofing team specializes in offering cost-effective retrofitting services to ensure your business building has a protective cover. We understand that the Grimsby climate presents a unique challenge, from freeze-thaw cycles in the winter to intense heat in the summer, high humidity levels, and storms. That is why your commercial building needs a strong roof.

    The cost of metallic flat roof installation is low, and these roofs last for decades. However, that does not compensate for the roof’s susceptibility to corrosion and rust after prolonged exposure to the elements. If you have a low-slope metal roof assembly and you need a more energy-efficient option, you don’t need a complete flat roof replacement. A retrofit is a cost-effective option if the existing roof deck is structurally sound.

    The Watertite Roofing team can install high-quality PVC roofing membranes over existing roof structures. With our roof retrofit services, you will get a new flat roof without incurring the high cost of an entire roof removal & replacement in Grimsby. Let our professional roofers inspect your existing roof to determine if a retrofit is possible.

    Commercial Flat Roof Repairs

    Our team of flat roofing experts is knowledgeable and skilled in all aspects of commercial and industrial flat roofs. Whether you are dealing with emergency leaks or you have scheduled a professional roof inspection, you can expect professional services from our trained and certified roofing experts. We have been in the roofing industry for five decades. That’s how you know you can rely on our team.

    Flat roofing issues can happen at any time of the day. Whether it’s a roof leak or storm damage, the Watertite Roofing team offers emergency repairs and other services around the clock. Even when you identify minor signs of damage, let our experienced roofing experts inspect your roof, determine the extent of the damage, and fix it. Contact us if you notice the following signs that your roof needs repairs.

    • Formation of water pools on your roof due to improper drainage.
    • Roofing membrane forming bubbles or blisters.
    • Membrane tears or cracking on various parts of your roof.
    • Damage to the roof’s flashing.
    • Damaged top coat due to strong winds and other harsh elements.
    • Unexplained sudden increase in your building’s heating and cooling costs.

    Some signs of flat roof issues, like minor blistering, are easy to ignore. However, they can escalate and cause extensive damage, requiring costly repairs. That’s why you should contact our team for leak repairs to prevent interior damage and extend the lifespan of your commercial flat roof. From the moment you make first contact, you can expect top-notch services in a timely manner.

    Regular Maintenance for Commercial Flat Roofs

    Watertite Roofing has been the commercial flat roofing contractor for roof maintenance services in Grimsby for over five decades. After all these decades as experts in flat roofing, we know what your business building’s roof needs to withstand exposure to harsh climate elements and last for decades. If we notice any issues that require repairs, we will work with you to get your roof fixed.

    Routine inspections or regular maintenance protect your commercial flat roof from the damage that occurs before you start seeing water dripping from your ceiling. During roof inspections, our team of skilled roofers pays attention to the following:

    • The rain collars on heat stacks and cones.
    • Roof drain pipes and scuppers.
    • Curb flashing, perimeter flashing, and the entire roofing membrane.
    • Seals and terminations to roofing curbs for roof protrusions such as skylights or HVAC equipment.

    After the inspection, we will provide a detailed report outlining the work completed, any roof damage identified, and repair recommendations. At Watertite Roofing, we recommend combining our thorough flat roof inspections with routine maintenance. This can help identify any issues deep in the insulation and the underlying roof structure.

    Retrofit Roofing Vs. Roof Removal & Replacement

    When it comes to roofing, industrial and commercial building owners in Grimsby face unique challenges. From the need for a cost-effective roofing option to the region’s harsh weather conditions, choosing the right roofing option is crucial. At Watertite Roofing, we recommend retrofitting flat & low-slope roofs rather than removing the old roofing substrates and starting from scratch.

    With a retrofit, we install a new PVC membrane system over your existing roof. If your building has a flat or low-slope roof, our team of roofing professionals can apply a PVC membrane overlay directly over the existing surface. This way, we avoid major roof tear-off work, reduce landfill waste, and keep your operations running with minimal downtime.

    Our clients also benefit from improved waterproofing, better thermal performance, and long-term resistance to UV and chemical exposure, as well as significantly reduced labour costs for the project. On the other hand, Roof removal & replacement involves removing the entire roofing system. It is more time-consuming and more expensive. We only recommend this option when both the roofing membrane and the underlying structure are extensively damaged or no longer safe to support a new roofing membrane.

    Our Proven Flat Roofing Assessment Process in Grimsby

    Every flat roofing project in Grimsby, ON comes with its own set of conditions that must be evaluated before any work begins. From commercial buildings and mixed-use properties to industrial facilities, each commercial flat roof is unique. For this reason, our professional roofing services always start with a comprehensive on-site assessment conducted by our experienced staff to ensure the most effective and cost effective roofing solutions are identified for your specific property.

    During our site visit, we assess a wide range of factors that influence system selection, project scope, and overall pricing. These include the size and configuration of the roof, the condition of existing roofing materials, insulation performance, and drainage efficiency. We carefully look for signs of ponding water, weather damage, leaks, and potential structural concerns that could impact the durability and reliable performance of the roofing system over time.

    Additional considerations such as roof access, safety requirements, and the ability to complete work with minimal disruption to day-to-day operations are also reviewed. Pricing can vary depending on whether the project involves targeted roof repair or a full roof installation, the complexity of the building, and how existing roofing systems align with modern energy efficient upgrades. Opportunities to improve efficient drainage, reduce cooling costs, and plan for future enhancements such as solar panels are also identified during the assessment process.

    By conducting thorough inspections and clearly explaining our findings, we provide property owners in Grimsby with transparent recommendations and competitive pricing they can trust. This site-specific approach ensures each roofing project meets current industry standards, protects valuable assets, and delivers dependable service supported by long-term performance and proactive maintenance programs.

    If you are planning your next roofing project in Grimsby, our team is ready to assess your roofing needs and provide a professional on-site evaluation along with a no-obligation free quote.

    FAQs

    Generally, commercial flat roof maintenance should be handled by professionals. Commercial roofs cover large surface areas and require specialized tools and expertise. Tasks such as detailed inspections, crack repairs, and flashing resealing must be performed by an experienced commercial roofing contractor to avoid costly damage.
    When a flat or low-slope roof begins to fail, the two main options are retrofit or full removal and replacement. In most cases, retrofitting is recommended because it offers strong performance, lower material costs, and minimal disruption to business operations. Full replacement is only advised when the roofing system and underlying structure are severely damaged.
    It is recommended to schedule commercial roof inspections and maintenance in the spring and fall. During these inspections, the roofing team conducts a thorough assessment of the roof system and addresses any identified issues, ensuring the roof can withstand Grimsby’s harsh climate conditions.
    Most high-quality commercial flat roofing materials are designed for durability, but poor installation and lack of maintenance can shorten their lifespan. With professional installation and routine maintenance, most commercial and industrial flat roofing membranes can last 25 years or longer.

      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.
