Why are There So Many Types of Commercial Roofing?

All commercial buildings serve a different purpose. The functionality of the building will largely impact the type of commercial roofing material you have installed. 

For instance, some buildings have flat roofs:

  • Warehouses
  • Strip malls
  • Storage facilities
  • Schools 
  • Office buildings
  • Even some more modern homes and condos

Alternatively, other commercial buildings have sloped roofs, such as:

  • Apartment buildings and condos (typically not older highrise models)
  • Townhouse and duplex complexes
  • Churches
  • Historical buildings

Depending on the functionality of the building, a specific roofing material is needed. But first, let’s take a look at some other factors to consider.

What to Look for in a Commercial Roof?

There are three main things you should consider when shopping around for a new commercial roof, whether you’re looking to replace your current one or to install it on a new development.

1. What is your budget?

Similar to residential roofing, commercial roofing materials have varying costs, depending on the quality, thermal insulating capabilities, and other factors. Before choosing your roof, it’s important to have a budget in mind. This will not only help you narrow down your search, but it’ll also help you have a firm number in mind while you’re receiving estimates.

2. Is the roofing material energy efficient?

Here’s an area where many property owners struggle: is it better to have a higher upfront cost, but save more over the long run on energy bills or vice versa? Our advice is to typically take the energy savings. Not only will this save you more money in the long run, but it can also help improve the resale value of your property if you ever choose to sell in the future.

3. Durability and Weathering

There’s no denying it: Edmonton has seen its fair share of weather extremes. From blizzards, to ice, to rain, to sunshine, we see it all. That’s why it’s important to choose a roof that can weather any storm. You’ll want to pay close attention to: tear & puncture resistance, fire resistance, and wind resistance.

Types of Commercial Flat Roofing

There are a few different types of flat roofing material available. They range in cost, benefits, and more. Let’s take a closer look!

1. Built-Up Roofing Membrane (BUR)

BUR is your standard flat roofing composition, comprised of several layers, includings:

  • Decking
  • Insulation 
  • Asphalt
  • Venting base
  • Ply sheet
  • Gravel and asphalt mixture

This is a more flexible roofing option, since the number of required layers can vary based on climate and functionality. It’s also one of the older roofing systems. 

BUR roofs typically last around 20 – 30 years and cost anywhere from $5.50 – $8 per square foot. 

2. Thermoset Roof Membrane (EPDM)

EPDM is a more innovative option. This roll-based system is extremely durable, easy to maintain, and is resistant to UV light. Due to this resistance, it can also help decrease energy bills while preventing fading. 

Typically, EPDM comes in either black or white rolls, lending you a bit of versatility when it comes to style options. It’s also made of synthetic rubber, making it resistant to pollution. 
EPDM roofing installation costs anywhere between $4 – $8 per square foot. Similar to BUR systems, it lasts between 20 – 30 years with proper maintenance.

3. Thermoplastic Roof (TPO & PVC)

This lightweight option is a popular choice for restaurants, since it’s resistant to chemicals and fats. It’s also UV resistant and prevents tears or punctures. Other benefits include: high wind tolerance, excellent weatherproofing, and holds up well in high temperatures. 

TPO & PVC commercial roofing typically costs between $3.50 – $7 per square foot. These roofing systems last about 20 years.

Types of Commercial Sloped Roofing

Not all commercial roofs are flat. There’s a wide-range of sloped commercial roofs, especially as multi-resident housing becomes more and more popular.

Let’s look at a couple different types of commercial sloped roofs:

1. Asphalt

Asphalt is by far the most popular choice for sloped commercial roofs in Edmonton. They come in a wide-range of colors, making it a versatile choice. Depending on the type of asphalt shingle you have installed, the cost and longevity range.

For instance, our asphalt shingles are designed to withstand the extremes of our Albertan climate. They come with a 20 year warranty (please replace with accurate warranty), and will offer long-lasting protection against rain, snow, UV light, and hail.

2. Metal

Metal roofing in Edmonton is becoming more and more popular, mainly because of its durability and long lifespan. While it’s not as popular in commercial sloped projects, it’s still a great option if you’re looking for a longer lasting roof with little maintenance requirements.

3. Composite

Composite roofs are typically made of rubber, plastic, or other synthetic materials, including polymers. Some even consist of recycled components. They are designed to mimic the look of asphalt, slate, or tile roofing, and although they are more expensive than asphalt, they last longer (up to 50 years). 

It’s important to note that while high-quality composite roofing is a great option for a sloped commercial roof, there are low-grade options that can cause a range of issues, including reduced insulation and freezing and cracking in the winter. If you do opt for this roofing type, make sure you only hire a reputable, trusted roofing company with a warranty to back up their product.
