Calgary AB’s Top Types of Commercial Roofing Materials

Single-Ply Membranes

Single-ply membranes are one of the famous types of commercial roofing flat roof types for corporate and industrial properties in Calgary AB. Because they are extremely cost-efficient, durable, and require less maintenance, single-ply membranes are a staple of the commercial real-estate industry.

Unfortunately, they have very little aesthetic appeal. In contrast, they can withstand adequate roof traffic and will withstand multiple harsh storms before they will need major repairs or a complete replacement.


Ethylene propylene diene monomer (EPDM) or rubber roofs as most call them are a primary recommendation of most contractors.  They are quick and easy to install. In fact, contractors can spend an entire week installing an EPDM roof from start to finish.

Manufacturers make them with reinforced slate and sawdust and recycled rubber they source from discarded yet roadworthy tires and durable boots. They have made the list of top types of commercial roofing materials because of their cost-efficiency. They only cost about $0.4 per square foot and last for 20-30 years.


Thermoplastic polyolefin (TPO) is the improved version of EPDM roofs. One of the primary selections for best types of commercial roofing materials, they have better aesthetic appeal than the black and blank look of EPDM roofs.

The white-colored membrane can reflect UV rays better than EPDM roofs and last for 20-30 years. In addition, they withstand heavy foot traffic and can carry some equipment such as a handful of split-type air-conditioning unit exhausts.

However, TPO roofs carry a heftier price tag if you compare them with EPDM roofs. They cost about $6-8 per square foot.

Thermoplastic polyolefin has a white or light-colored surface that can repel UV rays better than EPDM or rubber roofs.


Polyvinyl chloride (PVC) is the same material plastic piping manufacturers use for plumbing needs. However, they are one of the primary choices for best types of commercial roofing materials because of their exceptional durability and capability.

PVC roofs have a carrying capacity of 300 pounds per inch (PPI). Therefore, they can carry numerous numbers of split-type air conditioning sets. In addition, they come in various colors and can last for 50-60 years on average.

Modified Bitumen

Gone are the days when commercial building roof structure installation requires a work time-out because of smelly chemicals emitting from freshly-installed tar and gravel roofs.

Modified bitumen is one of the best types of commercial roofing materials because it is quick and easy to install.

Contractors will unroll the modified bitumen seams. Then, they will iron them out and create overlaps with each square. Lastly, they will install them using a heat-welder or a torch.

In doing so, modified bitumen roofs will melt all over the flat roof structure and create a watertight seal all over the roof. While they last only 20-30 years, they are quick and easy to replace too.


Corrugated and standing seam metal roofs work great for sloped commercial properties. However, we object heavily to their use with flat roof systems for commercial buildings because they are prone to denting. In light of this, the roof material can tear apart and become inefficient because of foot traffic.

Metal roofs have a lifespan of over 70 years. In fact, they require the least maintenance of all commercial roofing materials. The repainting of the roof with acrylic or elastomeric paint and fastener or screw checkups and adjustments is all it needs to live beyond 70 years.

However, they can be quite expensive. Metal roofs cost about $10-$15 per square foot. Therefore, consider it a long-term property-protective investment.

Commercial metal roofs only work with sloped roofs. They are excellent investments because of their 70 year lifespan (which can stretch even more in some cases).


Commercial property owners find concrete tiles or slabs as a primary roofing solution. In fact, most corporate property owners find them the most efficient roofing material possible because of their lifespan.

Concrete tiles can last for 60-70 years with effective maintenance. On the other hand, concrete slabs, which are practically naked concrete tile roofs, have the same average lifespan and require no maintenance.

However, they are quite expensive in terms of materials, equipment, and labor. It might take a few months for any roofing contractor to finish a concrete tile or slab roof.

Green Roofs

Green roofing undergoes the same process and length of time as concrete slab roofs. The only difference is the material contractors will use.

A green roof requires numerous waterproof membranes that will allow it to hold soil and guide moisture towards pipes that go through the downspout. Property owners can choose different types of plants and vegetation to grow on top of their roofs.

Green roofs offer plenty of advantages including local tax exemptions and reduced utility costs. However, they are laborious and take time to construct. Additionally, it has great advantages for residential properties too!

Will Commercial Roofing Materials Work Well For My Home?

What is commercial roofing? It’s a process involving commercial and industrial structures. However, the materials it uses is quite similar to residential roofing.

The requirements for excellent residential roofing are the same as commercial roofing. However, there is one difference: most commercial properties have flat roofs.

Therefore, a residential property with a flat roof can use these top choices for commercial roof materials. Sloped properties may find using concrete slabs or tiles, single-ply membranes, or modified bitumen, to introduce little to no aesthetic appeal at all, and curb appeal is definitely important for residential properties.
