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.
