How Long Does Your Type of Commercial Building Roof Typically Last?

Aug 28, 2019

The lifespan of your commercial flat roof in Toronto can vary drastically and depend on several factors. For starters, the type of roofing system installed and the quality of workmanship will largely impact the durability of your flat roof and how long it will last. In addition, there are other factors to consider when knowing how long your commercial or industrial flat roof will last. Not only will the type of roof you install matter, but the care you take in preserving its lifespan will too.

When it comes to commercial flat roofs in Toronto, there are some things you should know. A flat roof, for example, will not offer as much drainage as traditional pitched roofs. This means that water can become trapped in any holes or seams in the roofing membrane and decrease its lifespan if not taken care of. So, if you’re not adamant on commercial roof maintenance, the materials used to make your commercial roof were of low quality, or if the original contractor did not properly seal all parts of the roof, then its overall lifespan will become negatively affected.

Types of Commercial Roofing Systems in Toronto 

There are several types of flat roofs that a commercial or industrial building might have. Each one has a slightly different lifespan, installation process, materials, and cost. So, which is best for your property?

Let’s take a look at these different commercial roofing system types and how long they typically last. 

  1. Built Up Roofing Systems 

Built Up Roofs (BUR) are hot asphalt-based, multi-ply systems that are ideal for both sectional and complete flat roof replacements and repairs. BUR is made up of alternating layers of asphalt and other reinforcing materials. The result is a highly durable waterproof membrane to provide longevity and effectiveness for your commercial building.

How long does Built Up Roofing typically last? 

Built Up Roofing is a reliable, handcrafted method that has proven its effectiveness in Toronto’s tough and rather unpredictable weather. Durable and water-resistant, BUR roofing has been sealing and protecting flat roofs for almost 200 years. This type of commercial roofing system typically lasts anywhere from 20 to 30 years when installed and maintained properly.

  1. EPDM Roofing Systems

Ethylene Propylene Diene Monomer (EPDM) is comprised of synthetic industrial grade rubber that comes from a combination of ethylene propylene and diene. EPDM roofs are known to provide a longer-than-normal lifespan thanks to its highly flexible, yet durable membrane.

How long does EPDM roofing typically last?

EPDM rubber roofing can last anywhere from 20 to 30 years. This type of roofing can be applied in three thicknesses: 45 Mil (thousandths of inch), 60 Mil and 90 Mil. In fact, EPDM is so effective that even the 45 Mil membrane is sufficient for most small- to medium-size commercial or industrial flat roofs.

  1. PVC Roofing Systems

Polyvinyl Chloride Roofing (PVC) is a type of single-ply roofing membrane that is generally seen on flat or low-sloped building structures. PVC is highly reflective and contains life-extending components such as cool roof pigments, UV stabilizers, and other materials to increase durability. This type of roofing system is also very cost-effective, making it suitable for flat roof repairs.

How long does PVC roofing typically last?

PVC roofing membrane is the third-most widely produced synthetic plastic polymer in the world. You can be confident when choosing PVC roofing for your commercial property; it will typically last anywhere from 25-30 years when properly installed and maintained.

  1. TPO Roofing Systems

Thermoplastic Polyolefin (TPO) is a single-ply reflective roofing membrane made from a mixture of polypropylene and ethylene-propylene rubber. TPO roofing systems are most commonly seen on malls, shopping centers, warehouses and expansive office complexes.

How long does TPO Roofing typically last?

While not as flexible as traditional PVC, TPO is less expensive and can generally last anywhere between 15 to 20 years. TPO is a great a cost-effective, yet very dependable alternative for most commercial or industrial flat roofs in Toronto.
