Each Tillsonburg commercial building and industrial facility has unique flat roofing needs. That’s why our skilled roof installers assess each property carefully before installing, retrofitting, or replacing commercial flat roofs. Here are the top commercial flat roofing services we provide:
Installing a commercial flat roof requires careful planning and skilled workmanship. After all, your property’s roof must protect your commercial building, have an efficient drainage system, and withstand changing weather conditions. At Watertite Roofing, we assess the building type and identify the most suitable roofing system for long-term performance.
Our team follows an effective installation process that ensures the PVC membrane is securely in place to prevent future problems such as water pooling or seam failure. We utilize high-quality materials from trusted manufacturers, such as Duro-Last and the Canada-made Goliath roof system. This way, we guarantee the best flat roof installation services in Tillsonburg, Ontario.
Commercial flat roofs in Tillsonburg are exposed to constant pressure from weather, foot traffic, and mechanical equipment (installed on the rooftop). Even a minor issue, such as a loose seam or a punctured membrane, can allow water and excess moisture to infiltrate the underlying roof structure, causing damage. Over time, this may lead to rot, mold, and rising utility costs (due to insulation damage).
At Watertite Roofing, we offer timely flat roof repairs to prevent seemingly minor issues, such as a loose seam, from causing extensive leaks. Our process begins with a complete roof inspection to identify the cause of the problem. We carefully inspect drainage areas, rooftop equipment, and nearby structural components.
Once we identify the roof issue, we perform targeted repairs to fix the damage and restore the roof’s function without unnecessary disruption to your operations. We also offer emergency repair services for sudden leaks or storm-related damage.
Additionally, we offer regular maintenance services, which include routine roof inspections, cleaning, and prompt repairs. We understand that freeze-thaw cycles, debris buildup, and severe snow-loads can strain your roofing membrane, which creates weak points. Our maintenance services help prevent early roof deterioration, reduce long-term costs, and maintain consistent roof efficiency.
When a commercial flat roof begins showing signs of wear, a full roof replacement isn’t always required. In many cases, the existing insulation and roof deck remain completely sound—especially on commercial and industrial buildings in Ontario. During a detailed roof inspection and assessment, our skilled professionals at Watertite Roofing evaluate the condition of the roof deck, insulation layers, and overall assembly. If the insulation is dry and undamaged, and the deck is structurally sound, we can install a retrofit or overlay system directly over the old roof. This approach works exceptionally well with high-quality materials such as the Duro-Last single-ply PVC system and the Canada-made Goliath Roofing System, both of which are engineered for durability, longevity, and excellent performance on flat roofs.
Choosing a retrofit installation allows businesses to protect their property while avoiding the cost and disruption of a full tear-off. This method preserves valuable insulation, reduces labour costs, minimizes waste, and shortens the installation process—all while providing a durable, energy-efficient roofing solution. With proper installation by our experienced team and licensed contractors, retrofit systems using Duro-Last or Goliath membranes can achieve manufacturer-supported system guarantees of 15 or 20 years. For businesses in Tillsonburg Ontario, St. Thomas, London, and surrounding regions, a professionally installed overlay offers a reliable, cost-effective way to enhance protection, extend the lifespan of the roof, and maintain long-term performance with confidence.
PVC flat roofing membranes are a proven choice for commercial and industrial buildings, offering exceptional durability, energy efficiency, and long-term protection. At Watertite Roofing – Specialists in Flat Roofing Since 1976, we recommend high-quality systems such as Duro-Last and the Canada-made Goliath Roofing System for their superior resistance to leaks, UV exposure, and harsh Ontario weather. These membranes are lightweight yet strong, making them ideal for flat roofs where longevity and minimal maintenance are priorities. Both Duro-Last and Goliath systems can be installed as new roofs or retrofit overlays, providing businesses with reliable, long-lasting roofing solutions backed by manufacturer-supported warranties, helping protect your investment and ensure peace of mind for decades.
Bright-colored PVC membranes, such as Duro-Last and the Canada-made Goliath Roofing System, are designed to reflect a significant portion of sunlight, reducing heat absorption during warm months. This reflective quality helps lower the strain on indoor cooling systems and decreases energy consumption for many commercial and industrial buildings across Ontario.
Both Duro-Last and Goliath roofing systems offer excellent energy efficiency, with Duro-Last holding one of the highest retained reflectivity ratings under the EPA’s ENERGY STAR® Roof Products Program. For property owners, these high-performance membranes provide long-term energy savings, improved indoor comfort, and durable, low-maintenance protection for flat roofs.
PVC flat roofing membranes such as Duro-Last and the Canada-made Goliath Roofing System are engineered with strong, high-performance materials that resist a wide range of damage. These membranes can withstand fire, chemicals, grease, sharp objects, and high-strength winds, making them ideal for commercial and industrial buildings across Ontario.
Both systems are constructed with a specialized PVC formulation reinforced with a scrim layer, providing long-lasting durability and reliable protection for flat roofs. For businesses and property owners seeking a sturdy, low-maintenance roofing solution, Duro-Last and Goliath membranes offer superior performance, energy efficiency, and peace of mind for years to come.
PVC flat roofing membranes such as Duro-Last and the Canada-made Goliath Roofing System are available in a variety of colours, including white, terra cotta, tan, gray, and dark gray. These options allow commercial and industrial building owners to select a roof that not only delivers superior performance and durability but also complements the style of their property or meets specific design requirements. With this range of colour choices, businesses can enjoy a flat roofing system that provides long-lasting protection, energy efficiency, and an aesthetic that enhances the overall appearance of their building.

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.
