What is the best commercial flat roof system?

Aug 25

We've discussed in many of our blog posts that it is possible for a commercial building to have a roof system that's not ideal for it. Sometimes, builders will install an inappropriate roof on buildings with flat roofs. Inexperienced roofing contractors or novice building owners can install flat roofing systems for commercial buildings that aren't suitable because they don't know all the factors to consider when choosing the suitable roofing material from the many options.


Sometimes, it is more common for the type of business to change throughout a building's history. While the original commercial roof was an excellent fit for the building's initial purpose, it may now be inconsistent or too old to cause leaks.

It doesn't matter what; it is essential to know the basic properties of your flat roofing system to make informed decisions about preventative maintenance and repairs and possible future replacement. This post will give you an overview of the most popular flat roofing materials and how to decide if your roof is the right one for you.


Although residential and commercial roofs serve the same purpose of protecting your home or property from the elements, there are some differences. The roof's slope is the main difference between residential and commercial roofing systems. The building's size determines this. Residences have a steeper slope roof than commercial roofing. 


This is due to their smaller size and use of materials like architectural tile, asphalt shingles, and slate. Commercial roofs are typically flattering or less sloped due to the greater size of commercial buildings. There are many options for commercial roofs. These materials depend on the structure of the building as well as other factors such as climate conditions (e.g., extreme heat or cold) and if the surface must withstand heavy foot traffic.


There are considerations when choosing the right commercial roofing system in Toronto for your business. Because different kinds of businesses have specific needs, you need to consider the type of facility you work with. It will be easier to decide if you are familiar with the different commercial roofing systems.


Once you've identified the roof's slope, you can choose the right type of roofing system to meet your needs. These are the most popular commercial roofing systems.

Single-Ply Roofing

These roofs are made from TPO, PVC, or EPDM. These roofs are highly flexible and robust materials that many building owners prefer. They resist cracking, peeling, and other weathering. They are intended to be used in one layer. The single-ply roofing industry has two main types: thermoplastic and thermoset membranes.

TPO (Thermoplastic polyolefin).

This material is used most often on low-slope roofs. It includes reinforced roof sheets with heat-welded seams that are highly reflective and reinforced roof sheets. TPO is a single-ply membrane polymerized together with polypropylene or ethylene-propylene rubber. TPO belongs to the thermoplastic membrane group and is available in many colors, but the most popular ones are white, gray, and tan. Several ways to install the membrane include adhesive, mechanically attached, and ballasted.

PVC roofing material consists of two layers of PVC and a polyester reinforcement scrim. The membrane is UV-resistant because the top ply has additives. The bottom ply, usually darker in color and has plasticizers to allow for greater flexibility, makes installation much more manageable. A PVC membrane has many other benefits, including durability, fire resistance, and longevity.


PVC can also be weldable, which means it can be welded onto another sheet to make it watertight. You can make PVC sheets look like a standing seam roof system. This is done by welding a prefabricated rib to the surface. It costs much less. PVC membranes can also be recycled and reused in new sheets.

EPDM Roofing (Ethylene Propylene Diene Monomer)

What is EPDM roofing? The letters are for "ethylene propylene monomer," an obscure chemical compound known for its toughness and elasticity. EPDM roofing is a material that can withstand intense ultraviolet light and all of the sun's harmful rays. EPDM rubber roofing, a popular commercial roofing material, is highly sought-after because of its low cost and high resilience. EPDM roofing membranes are made from natural gas and oil. EPDM roofing material can be found in low-slope commercial buildings around the globe.

Modified bitumen roofing systems: This modified bitumen roof is made from asphalt and a unique chemical polymer that provides flexibility and resistance to temperature extremes. It can be installed in multiple layers, including hot-mopped asphalt or torch-applied adhesives. This roof is suitable for installation in all four seasons. To form a secure bond, the seams are melted together. They are resistant to fire, wind, and hail, which makes them immune to damage from a storm.

Built-Up Roofing Systems

Built-up roofing is one of the oldest roofing systems on the market. It has 3-5 layers to enhance protection in extreme climates with high and low temperatures. Built-up roofing, also known as BUR for short, has been around for more than 100 years.

Steel Roofs

Metal roofing is well-known for its beauty, durability, and longevity. Many building owners love the durability and look of metal roofs. They can be used on steep and low-slope roofs. Many homeowners and builders choose metal roofs over traditional shingle roofs because of their longer life span and outstanding durability.
