Best Flat Roof System for Commercial Use

To find out the best flat roof system for your Toronto ON building, you have to exhaust all possible options before you can narrow down your decisions.

You can look into the list that we’ve prepared so that you would be able to identify both the good and bad sides. Does this even matter? Yes, it does. Fully understanding the capabilities and drawbacks of certain roofing options can help paint the bigger picture. Remember that roofing is a huge investment, therefore it’s imperative to carefully decide on where your money will go. In terms of its performance, will it be worth it and will it align with your priorities? These are very important questions that you need to address in the pre-construction and planning stages.

Let’s begin…

Modified Bitumen

Modifies bitumen has been widely used for different purposes and one of them is for commercial roofing. Homeowners choose modified bitumen because it is proven to be sturdy and weather-resistant. It’s a single-ply roofing material that contains either polymers or fiberglass for durability. Installation-wise, it can get complicated and hazardous. It makes use of a blowtorch to secure the base material in place. This process makes validates the need to hire roofing experts with the right set of skills especially when it comes to the handling of tools and equipment. On the other hand, repairs and maintenance should be fast and easy with the help of professionals.

Mastic Asphalt

One of the pioneers in flat roofing, mastic asphalt has been available for many centuries now. Building owners and contractors alike choose MA because of its tried and tested superior strength.

The only thing to note about asphalt is that it could be difficult to install. Only trained workers can successfully build reinforced joints to support the thick and heavy material during the installation process. While the initial costs are affordable, labor requirements may affect the overall price.

Built Up Roof

A built-up roof or tar and gravel has impeccable durability and longevity. As a matter of fact, they can last for up to 40 years or more given the right attention and, of course, with professional care. Roofing companies warn homeowners who live in areas with extreme sun exposure as it can cause tar to shrink over time. The good news is that it is waterproof so you wouldn’t have to worry about water damages provided that it was installed properly. BUR is also heavy which becomes a major factor during installation. It may be complicated to install but for expertly trained workers, there is a way to ensure the success of a BUR installation project.


Metal isn’t a popular choice years ago but now it is one of the most in-demand flat roofing systems. Why? Here’s what you need to know…

Metal is used for many varying purposes because this type of material can last for a really long time. It’s not only long lasting but also equally durable. If you are also looking for an energy-efficient roofing solution, you can explore metal’s capabilities. It can reflect sunlight to prevent the roof from absorbing heat which could be inconvenient especially in summer. As it blocks off heat, it also helps business owners cut down on excessive energy consumption.

While these qualities are really promising, there’s no perfect roofing system. A metal flat roof can be expensive. If you have the budget for it and if it passes your design requirements, this might be a good option. If you’re worried about rusting, speak to a local roofing contractor to ask about roof coatings to protect it from harmful elements.

EPDM or Rubber

Ethylene propylene diene monomer (EPDM) or simply rubber is not a new concept to us. We see rubber almost everywhere, in your garage, in your car, and many other parts of the house. People like rubber because it’s waterproof but there’s more. Rubber is also eco-friendly as it’s produced from recycled rubber seamed as one. Hence, it doesn’t end up useless in landfills.

Rubber is ideal for commercial flat roofing because it is weather-resistant, flexible, and, of course, durable. The cost wouldn’t be much of an issue, too, as it is way affordable than the high-end options. If you’ll choose EPDM for your home, watch out for leaks as the edges may become prone to water penetration as they deteriorate.


Polyvinyl chloride or PVC is reinforced with fiberglass or polyester making it fire and UV ray resistant. Like most flat roofing options, it is also durable and waterproof but if you are concerned about its composition, you have to know that it’s made from some harmful chemicals. While it doesn’t really be directly hazardous to you as an end user, it can damage the environment in the process.


Thermoplastic polyolefin or TPO is a lesser harmful flat roofing system because it does not have chlorine as compared to PVC. Its characteristics are similar to PVC as it can also retard UV rays. It’s also lightweight and strong. In order to successfully prevent water and moisture penetration, you have to hire an experienced roofer to install this roofing material.
