We believe in providing our customers with functional and lasting roofing solutions. That’s why we recommend flat roofing materials that come with a comprehensive warranty. Additionally, we offer a workmanship warranty on all our commercial roof installations, retrofits, and full replacements.
When you choose the Watertite Roofing team for your commercial flat roof repairs, installations, routine maintenance, or replacement, you can rest assured of long-lasting protection for your business building.
Watertite Roofing is a full-service, BBB-accredited commercial roofing contractor specializing in roof installations, restoration, and replacements. We aim to ensure your commercial building or industrial facility has an efficient roof that can protect it from water-related damage. The roof should protect the assets, business operations, tenants, or staff within the building.
Regardless of the current condition of your commercial roof, you can contact us for the following roofing services:
Roof damage can disrupt your business operation and lead to costly future repairs. When you notice the earliest signs of flat roofing issues, we recommend taking immediate action. Contact Watertite Roofing right away for timely roof repairs. Here are the warning signs that your commercial building’s roof needs repairs:
Here at Watertite, our team of professional roofers performs thorough flat roof inspections to determine the nature and extent of your flat roof deterioration. Whether you’re dealing with roof leaks, punctured membranes, or a failing roof drainage system, our experienced team is available even for emergency repairs.
Flat roof assemblies and low-slope metal roofs are renowned for their durability, but over time, they can become corroded, start to leak, and become less efficient in terms of energy usage. When it’s time for a roof replacement, a costly project including the removal of your old roof and roofing insulation, and their full replacement, isn’t always necessary. At Watertite Roofing, we provide a thorough inspection of your roof and determine whether a full roof removal and replament is required, or whether we can more cost-effectively encapsulate your existing roof assembly through a roof retrofit or overlay, saving significant dollars in labour and materials.
One benefit of retrofitting instead of replacing the entire roof is that you have the opportunity to install energy-efficient and durable Duro-Last or Canada-made Goliath PVC roofing membranes at an affordable cost.
Retrofitting works only when the underlying roof structure (deck and insulation) is in fair condition. That’s why our expert team will first inspect your roof to determine its current condition. We’ll recommend full replacement if the roof deck is severely damaged or your roof is retaining moisture within the roofing substrates.
Proper maintenance can help keep your flat roof energy-efficient and functional. Ideally, you should get it inspected twice a year (once in Spring and again in Autumn). During the routine maintenance, we’ll clean your roof, inspect it, and identify even the seemingly minor signs of damage.
Any issues noted during the inspection will be addressed and fixed immediately to prevent further damage to your roof. For instance, loose seams or the earliest signs of flashing problems can be fixed before they turn into costly repairs.
In addition to routine roof inspection and maintenance, we offer seasonal roof inspections. When hailstorms, severe freeze/thaw cycles, high winds, and other forms of extreme weather occur, they can cause extensive damage.
Our roofing professionals can inspect your roof, assess the extent of the damage, and make the necessary repairs. At Watertite Roofing, we’re a trusted partner for regular inspections and roof maintenance services.
Duro-Last is North America’s top manufacturer of cutting-edge materials for commercial flat roofing. Their thermoplastic, single-ply roofing membranes are custom-fabricated to meet each specific roofing requirement. This approach to flat and low-slope roofing has revolutionized the modern roofing industry.
Here’s why Duro-Last and Canada-made Goliath PVC roofing membranes are widely chosen:
Duro-Last and Goliath flat roofing membranes are made of high-strength PVC (polyvinyl chloride). They can last 25 years or longer with proper maintenance. Note that the roof surface is designed to withstand punctures and damage associated with exposure to chemicals, UV rays, and fire.
Therefore, Duro-Last and Goliath PVC roofing membranes are suitable for commercial and industrial facilities in harsh climates. Our skilled team will recommend the top-quality materials for your roof and other accessories, such as insulation, skylights, and more.
Duro-Last and Goliath PVC roofing systems are designed with energy efficiency in mind. For instance, the roof surface is highly reflective to minimize heat absorption, which reduces the cost of indoor cooling during the summer.
Here at Watertite Roofing, we recommend roofing systems that match Energy Star requirements. After all, an energy-efficient roof allows Burlington property managers and owners to save on their monthly energy costs.
One aspect that makes Duro-Last an environmentally friendly roofing material is that it can be recycled. When you finally decide to replace your Duro-Last PVC membrane, it can be sent back to Duro-Last for recycling instead of disposing of it in a landfill. Work with the experienced roofers at Watertite Roofing to access the best materials for an eco-friendly roof.
The cost of commercial flat roof installation, repair, and replacement services in Burlington depends on many factors. These include the extent of the damage, the size of your roof, the cost of labour, and the overall complexity of your project. Therefore, it’s recommended to request a free quotation to get a reliable cost estimate and project timeline after the initial project assessment.
For example, the cost of patching small cracks or fixing minor leaks is significantly lower than the cost of repairing extensive damage to the roofing membrane or flashing. Similarly, the cost of retrofitting an existing flat or low-slope roof may be considerably lower than that of replacing an entire roof structure. Here are the factors that affect the total cost of flat roofing services:
The roof repair or installation process for a large industrial facility is complex and requires more labour hours than a project involving a small business building. Depending on the current condition of your roof, you may need repairs, partial replacement, or complete replacement.
The cost of labour majorly depends on your preferred roofing contractor and the prevailing labour prices. That means labour-intensive projects may cost more than minor roof repairs. Here are the estimated costs of labour for different flat roofing systems.
Pricing for flat roofing systems can vary significantly depending on the material, installation complexity, and long-term performance expectations. Single-ply systems like Duro-Last PVC roofing typically come at a premium because they are custom-fabricated, highly durable, and offer strong warranties with minimal disruption during installation. Goliath PVC roofing systems are also priced higher than basic membrane options due to their reinforced construction, superior chemical resistance, and longevity, making them a strong choice for commercial and industrial buildings. More economical systems—such as modified bitumen or basic EPDM—may offer lower upfront costs, but they often lack the lifespan, energy efficiency, and reliability of high-performance PVC roofing solutions.
