Your commercial property’s roof has two primary functions. First, it protects the entire building from water infiltration and damage. Secondly, it keeps all your assets safe, including business operations, staff, and tenants. Watertite Roofing is a full-service flat roofing contractor that can help you achieve the following:
A flat roof has distinct design features compared to a pitched roof. For instance, flat roofs are generally true to their name, and their topography is often dead-flat. This creates unique waterproofing challenges compared to pitched roofs that naturally shed water. A flat roof must be 100% sealed and waterproof, as it often collects water and drains much more slowly than a pitched roof.
At Watertite Roofing, we have provided flat roof installation services in St. Catharines and the Niagara Region for many decades. We have installed flat roofs on private properties, industrial facilities, and institutional properties. Therefore, you can rely on our expertise to ensure the following aspects of your new flat roof are handled carefully and professionally.
In addition, we use Canadian General Tower’s Goliath PVC single-ply roofing membranes. These roofing materials have more insulation and waterproofing benefits than other flat roof options, such as built-up roofing, modified bitumen, synthetic rubber, and thermoplastic polyolefin. With professional installation, regular inspections, and timely repairs, your PVC single-ply membrane roof can last decades while ensuring lasting protection for your commercial building.
Identifying and addressing flat roof damage early is crucial to preventing extensive damage and expensive repairs. Our team will inspect your commercial building’s flat roof for signs of pooling water or dampness, especially after heavy rainfall. Remember, standing water on a flat or low-sloped roof can lead to leaks and blistering if not addressed early enough.
Our skilled roofers will carefully assess certain areas where the roof surface intersects with flashing, which are vulnerable to leaks. If your roof has small cracks or minor leaks, we can patch them. However, we recommend a thorough inspection to identify and fix the underlying issue causing the leaks. Here are signs your commercial roof needs repairs.
Don’t hesitate to contact us when you notice punctures or splits on your roof. Don’t try to fix any cracks or repair leaks on your own. Our experienced roofers can help assess the extent of the damage and fix it before it causes further roof deterioration. If there’s significant damage, we often recommend replacing the damaged section to maintain the structural integrity of your roof.
Routine inspections and timely repairs are key to preventing costly repairs and extending your roof’s lifespan. During routine flat roof inspections, our team pays attention to every aspect of your roof. This allows us to identify any potential issues and recommend cost-effective repairs. We also clean your roof to prevent leaves and debris from clogging your roof drainage system.
In addition, we recommend seasonal roof maintenance. During spring, we’ll inspect your roof for damage caused by winter. We’ll also clear debris that may have accumulated during the winter and autumn. Remember, these inspections and maintenance processes are thorough, and we’ll locate any possible damage to your roof, no matter how minor.
During autumn, we will clear any blockages and debris accumulation due to heavy rainfall. We will prepare your commercial property’s roof for winter by ensuring your roof insulation and waterproofing are intact. Remember, a well-maintained roof protects your building from structural damage and improves energy efficiency.
When it comes to flat roof replacement, you can rely on our team to use the best quality roofing materials and advanced techniques to ensure durability and superior performance. Our recommended choice for flat roof replacements is the Canadian-made Goliath PVC single-ply roof system from Canadian General Tower. This roofing option is versatile, durable, and easy to manage.
Flat roofs are among the most preferred roofing systems for commercial properties in St. Catharines and across Ontario for many reasons, with cost-effectiveness topping that list. Flat roofs are affordable to acquire, install, and maintain. Here are other benefits associated with flat roofs for commercial properties.
Unlike pitched roofs, commercial flat or low-sloped roofs provide additional space that property owners can repurpose to add value to their building. For instance, you can turn your flat roof into a platform to install an HVAC system or solar panels.
You can also turn your rooftop space into a stunning garden. There are endless possibilities to transform the extra space to improve your property’s aesthetic appearance and value.
Another reason flat roofs are widely preferred in St. Catharine is the ease of access. Every commercial roof requires routine inspections and maintenance. Activities such as cleaning or solar panel installation can be quickly completed on a flat roof rather than a pitched shingle roof.
The slow-slope design of commercial flat roofs makes them safer to work on. Furthermore, the flatness of the roof makes it easier to complete inspections and repairs. Thus, routine maintenance for commercial flat roofs takes a shorter period than a pitched roof. That means short or no disruptions to your business operations during repairs, and much less liability.
You can use your flat rooftop in many ways. For instance, you can create a recreation area where the building occupants can take breaks. Let our team help you figure out cost-effective ways to transform your flat roof space to ensure functionality and improve the market value of your commercial property.

Flat roofing projects vary in scope, preferred materials, and required labour hours. That’s why we recommend requesting a free quote. We’ll provide detailed and customized cost information to help you make informed decisions and plan your budget more accurately. Here are the estimated costs (average) of various roofing materials.
| Type of flat roof | Average Replacement cost per square foot |
| Ethylene propylene diene monomer (EPDM) | $4 to $12 |
| Polyvinyl chloride (PVC) | $7 to $12 |
| TPO (thermoplastic polyolefin) | $7 to $12 |
| Modified bitumen | $8 to $14 |
| Asphalt & gravel built-up-roofing (BUR) | $10 to $20 |
The exact cost of your flat roofing project will depend on the following factors.
Larger commercial roofs require more materials, labour, and time, which directly affects the overall cost. Complex layouts or multiple roof sections can also increase project duration and difficulty. Each square foot adds to material use and installation effort. That’s why we first assess your roof before issuing a quote.
The condition of your current roof plays a significant role in pricing. If the roof is in good shape, a retrofit may be possible, whereby the existing roofing materials can remain in place and simply be encapsulated in the new roof system, providing significant savings on flat roofing materials and labour. However, roofs with excessive water damage or structural issues often need complete removal, which involves more labour, disposal fees, and preparation work, leading to higher project costs.
Not all roofing systems are priced the same. Premium materials like Goliath Roofing Systems offer long-term savings and superior performance but may have a slightly higher upfront cost. Your choice of insulation, membrane type, and installation method can impact the final price. However, various installation methods can be chosen from, providing cost-effective and competitive solutions.
Access to the roof can influence installation costs. Urban buildings with limited space or high-rise access may need specialized equipment or added labour. Active commercial spaces may also require scheduling around business hours to minimize disruptions. This can potentially increase time on site and overall labour charges for the project.

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.
