Successful flat roof installation requires careful planning, high-quality materials, and skilled labour. That’s why you need a team of trained, certified, and highly experienced flat roof professionals to handle every phase of your flat roofing project.
Every piece of waterproofing membrane, seams, and flashing plays a key role in the performance and longevity of your flat roof. At Watertite Roofing, we pay attention to the structural integrity of the underlying structure to ensure your roof is properly installed. We also install reflective roofing systems that do not absorb the sun’s heat, providing greater roof system longevity and building energy savings.
Regular inspections and timely repairs are key to ensuring your flat roof lasts decades. In addition to removing debris and shrubs from your roof’s surface, each type of flat roofing membrane has maintenance requirements.
We often recommend Goliath PVC roofing due to its durability, fire-resistance, and ability to withstand constant exposure to strong winds, hailstorms, and other harsh weather elements. It also requires less maintenance and is simple to assess and maintain, as it does not require a stone or gravel covering.
Routine inspections help identify leaks, ponding water, and other signs of improper drainage. We also pay attention to cracking, blistering, membrane shrinkage, and flashing issues. With our inspections and flat roof repair services, you can quickly address such problems before they cause extensive water damage to your building.
Failing to address various flat and low-slope roof issues early enough may necessitate costly repairs and shorten your roof’s lifespan.
Like pitched roofs, a flat roof has a specific lifespan. While this roofing option is durable, general wear and tear, weather elements, and water damage can weaken your roof. With proper maintenance, your roof may last decades. However, you’ll need to replace it at some point.
Here are the signs your building’s flat roof needs to be replaced.
The key to determining whether flat roof repair or replacement is required is to get an honest assessment completed by one of our trusted flat roofing professionals. We’ll assess the extent of leaks, cracks, and other types of damage and provide unbiased advice and a free report containing photos from your roof and explanations.
We’ll help you compare the cost of repairs and the benefits of an entire flat roof replacement. This will make it easier for you to make informed decisions related to your business property’s roof.
At Watertite, we understand that if you plan to install a flat roof on a new construction project, you require different services from those of a property owner who needs routine roof inspections and maintenance. That’s why we follow a well-thought-out process that ensures each client gets customized services that match their roofing needs. Here’s what to expect when you choose our roofing services for commercial properties.
The journey to install, repair or replace a high-performance flat roof begins with a free consultation. Our industry-leading roofing experts will listen to your roofing needs, respond to your concerns, and schedule an on-site roof assessment.
During the roof inspection process, our experts will pay attention to the current condition of your roof, identify any underlying issues, and determine the suitability of repairs or replacement. The information gathered during this assessment guides the roofing solution we recommend and implement.
Our team of roofing professionals, supported by architects and engineers, will work closely with you to design a detailed flat roof installation, repair or replacement plan. We often recommend the Canadian-made Goliath PVC single-ply roofing system by Canadian General Tower, and we’ll help source the materials from Ontario’s top brands.
In addition, we’ll assess and upgrade your property’s drainage system to ensure compliance with industry standards and local building codes. The planning phase lays the foundation for your entire project and the long-term success of your roof.
Goliath PVC single-ply roofing is versatile and allows for different installation options. The retrofit or overlay installation method is ideal for buildings where the roof substrate is structurally strong and dry. Our installers secure the Goliath membrane over the existing roof. Retrofitting saves significant financial resources in terms of labour and material costs. We complete such installations within a short period to minimize disruptions to your business operations.
Suppose your property’s roof substrate is saturated with water or has suffered extensive damage. In that case, we recommend complete roof replacement. This involves removing the existing insulation and roofing material before we install the Goliath roofing option. Remember, installing PVC roofing membrane on a damaged area will only lead to further deterioration of your roof and structural damage to your property.
Our team will complete each task, from the initial site preparation to insulation, flashing, edge detail, and waterproof membrane installation. At Watertite Roofing, we often recommend polyvinyl chloride (PVC) single-ply membranes from Canadian General Tower’s Goliath Roofing Systems. Other materials used in flat roof construction include EPDM (ethylene propylene diene monomer), modified bitumen, built-up roofing systems (BUR), and TPO (thermoplastic polyolefin).
Once our team completes the installation, repair, or replacement of a flat roof, we’ll inspect the entire roof to ensure every task is completed to the highest safety and quality standards. We’ll check for efficient drainage, flashing, and secure seams. Remember, we provide a comprehensive warranty for each new flat roof we install, repair or replace.
As mentioned earlier, we specialize in installing Canadian-made Goliath PVC roofs. The cost of installing a Goliath PVC membrane to cover an existing flat roof ranges between $7 and $12 per square foot on average. Metal roof retrofitting (installing a single-ply membrane on an existing metal roof) costs between $8 and $14 per square foot on average. The cost of an entire flat roof replacement will depend on the scope of your project and other factors.
Here is the cost breakdown for other flat roof repair services for business properties in Niagara Falls.
| Flat roofing material | Average Replacement cost per square foot |
| EPDM (Ethylene propylene diene monomer) | $4 to $12 |
| TPO (Thermoplastic polyolefin) | $5 to $14 |
| PVC (Polyvinyl chloride) | $6 to $13 |
| Modified bitumen | $8 to $14 |
| Asphalt & gravel built-up-roofing (BUR) | $10 to $20 |

Flat roofs are the most preferred option in many commercial properties in Niagara Falls. Here are the benefits of installing a flat roof.
Flat roofs provide valuable exterior space that pitched roofs simply can’t offer. Commercial property owners can transform this extra space in different ways. For instance, they can install solar panels, HVAC systems, or even create rooftop gardens and lounges.
Our team will build your roof with these possibilities in mind. This added functionality enhances the usability of your property and can increase its market value.
Flat roofs are easy and safe to access. Our team can reach the surface quickly for routine inspections, cleaning, and repairs. This ease of access allows us to perform work more efficiently and with minimal disruption to your business operations.
Compared to steep-sloped or pitched roofs, flat roofs are safer to navigate. Our roofing professionals benefit from better footing and maneuverability, which reduces safety risks and helps complete projects faster. This allows property owners to manage emergency or routine roof maintenance with less hassle and lower safety concerns.
At Watertite Roofing, we aim to help commercial property owners enhance their buildings’ energy efficiency, functionality, and longevity through cost-effective flat roof repairs, installations, and maintenance.
