You can trust that the flat roof on your Welland commercial property will be treated with the full extent of our knowledge, expertise, and care.

Roof installation is an essential factor in commercial property construction. A stronger roof extends the lifespan of a commercial building. That’s why we recommend working with a reputable flat roofing contractor with an impressive record of successful projects. Let our trained, certified, and experienced roofers help handle your project, from initial planning and design to the final step.
At Watertite Roofing, we understand that there are different flat roofing materials. Our team will help you compare roofing material types and choose an option that best fits your commercial property for lasting protection. We often recommend the PVC (polyvinyl chloride) single-ply roof systems, such as the Canadian-made Goliath Roofing System by Canadian General Tower, due to their high quality, environmental friendliness, financial benefits, and long-lasting waterproofing ability.
Our team follows a well-thought-out, engineered, and customized process for new roof installation. We understand that improper installation of new flat roofs poses serious risks and liabilities, inconveniences associated with frequent repair, and potential penalties for building code violations. Our team will ensure your roof is properly installed to strengthen the structural integrity of your commercial building and protect your most valuable asset.
Proper flat roof maintenance is essential for efficient functioning and longevity. Your flat roof endures constant exposure to harsh weather elements such as heavy rainfall, snow, hail, high winds and UV rays, which can cause wear and tear over time. At Watertite Roofing, we provide preventive maintenance services to help identify and fix roofing issues before they escalate to extensive damage. This way, we help prevent costly repairs and business operations downtimes in the future.
In addition, we provide timely and effective flat roof repair services. Whether your flat roof is made of TPO (thermoplastic polyolefin), modified bitumen, built-up roofing, EPDM (ethylene propylene diene monomer), or PVC (polyvinyl chloride), you can count on us for reliable repairs and ongoing maintenance services. Here are some of the issues we help fix.
Contact us the moment you notice any signs of roof damage. Our team offers reliable emergency roof repairs and insights to prevent future commercial roofing issues. For instance, regular inspections and cleaning can help identify minor problems that, when addressed, can prevent roof damage and extend its lifespan.
Flat roofs are efficient and durable. Like their pitched or sloped counterparts, they have a certain lifespan. Over time, structural movements, weather elements, and general wear can cause roof deterioration. Regular professional inspections can extend the lifespan of your roof and ensure reliable performance. However, replacing your commercial or industrial roofing system may be beneficial under the following circumstances.
Flat roof repairs offer a more affordable and immediate solution to roof issues. However, there are circumstances when roof replacements are cost-effective. Let our team assess the signs of your flat roof damage and determine whether repairs will be efficient or if you need to replace the entire roof.

A high-performing flat roof starts with high-quality materials.

Our team also uses modern technology and proven installation techniques to maximize durability and efficiency.

Watertite Roofing specializes in flat roofing systems for commercial and residential properties. We often recommend the Canadian-made Goliath PVC single-ply roofing system. This is an advanced flat roofing system designed to ensure long-term protection for commercial buildings. Here are our PVC flat roofing installation, maintenance, and replacement services.
When we install the Goliath PVC single-ply system through an overlay or retrofit method, we eliminate the need to completely tear off the existing roof. This means fewer materials are needed, less waste is created, and significantly reduced labour costs.
Our flat roof installers are trained in overlay installation techniques and can work efficiently to complete your flat roof repair or replacement within budget and timeline. This approach is especially beneficial for large-scale commercial buildings where cost-efficiency is critical.
Our flat roofing solutions, especially the Goliath PVC roof systems, are designed to last decades while ensuring superior performance. When installed by professionals, these roofing options extend the roof’s durability and reduce the frequency of roof maintenance and replacements. Remember, Goliath roofing systems are known for their exceptional durability and resistance to general wear and tear.
With the installation of the Goliath PVC roofing system, we install a solar-reflective surface that provides energy savings and extends the life cycle of your building’s heating and cooling equipment. This translates into cooler interior spaces and lower cooling costs. The result? Lower monthly energy bills. We’ll carefully assess your building’s overall energy efficiency and recommend the best roof installation approach to improve it.
Some companies offer a recycling program, allowing commercial property owners to responsibly dispose of their old roofing materials. Instead of sending old PVC membranes to landfills, such programs offer you the chance to get those roofing materials recycled. This can reduce your roof’s impact on the environment.
Goliath PVC roofs are designed and engineered to withstand harsh weather conditions. They offer unmatched resilience and durability compared to most flat roofing materials. They have heat-welded seams and a watertight design to protect your business property from frequent leaks and give you the peace of mind you deserve.
Flat roofs offer extra space that you can repurpose to add value to your commercial building. Unlike pitched roofs, the extra rooftop space can serve as storage space for a heavy HVAC system. You can also install solar panels or turn it into a rooftop garden. There are many ways to transform the extra usable space to increase the value of your property.
The total cost of installing or replacing a flat roofing system varies widely depending on the scope of your project, application method (adhered or mechanical attachment), materials used, and the current labour costs. Here are the different factors we consider to determine the cost of installation.
| Roofing Material | Average Replacement cost per square foot |
| Modified bitumen | $8 to $14 |
| TPO (Thermoplastic polyolefin) | $7 to $12 |
| Asphalt & gravel built-up-roofing (BUR) | $10 to $20 |
| PVC (Polyvinyl Chloride) | $7 to $12 |
| EPDM (Ethylene propylene diene monomer) | $4 to $12 |
The total cost of installing, repairing, or replacing a flat roof depends on the type and condition of the existing roof deck, the number of rooftop units or penetrations, and whether the old roof needs to be removed. Other variables include the height of parapet walls, the thickness of the current and new insulation (if necessary), and how easy it is to access the roof.
Other factors that influence the cost of installing a flat roof include the time of year, weather conditions, and specific local permit or code requirements. Because no two roofs are the same, a site visit and professional assessment are essential. That’s why we recommend requesting a free estimate and scheduling a site visit.

Learn moreWhen 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.
