Why are flat roofs preferred for some commercial buildings?
Flat roofs have a number of advantages that are particularly well suited to commercial concerns. These advantages include:
- Lower costs. Low slope and flat roofs tend to use fewer raw materials than their higher pitched cousins. Installation of these roofing solutions is also relatively straightforward, which reduces labour costs.
- Added space. Space is at a premium in commercial buildings – the more space you have, the better. Flat roofing systems create space on your roof. You can install your HVAC system on a flat roof. You can store products on a flat roof. You can even design your flat roof to accommodate foot traffic and even vehicle traffic – flat roofs can provide extra parking spaces. Gardens, dining spaces, swimming pools – the sky’s the limit with a flat roof.
- Easy to maintain. It’s a lot easier to stand and walk on a flat roof than it is on a very sloped roof – and a lot less dangerous. Cleaning and repairing flat roofs is also a lot easier – that means labour costs are lowered, too.
- Durability. Flat roofing systems have been tried and tested in commercial applications for decades. Many flat roofing systems can last for 20 years or more. They’re also built to resist the snow, hail, and wind that come with Calgary’s severe weather.
What is the average lifespan of a flat roof?
The lifespan of a flat roof depends on the material used in its construction. Single-ply PVC and TPO roofs may last for 15-25 years, while modified bitumen roofs tend to last from 10 to 15 years. Conversely, a metal flat roof might last 40+ years, and built-up roofs (BUR) can last 15-30 years. Elastomeric bitumen roofing can often last 30+ years as well.

Types of flat roofs we install
Built-up roofs
Built-up roofing (BUR) is one of the most commonly used commercial roofing systems. Why? It’s relatively long-lasting, affordable, and it’s easy to maintain. It’s durable, so it can withstand the inclement weather we get so frequently here in Calgary, and it’s even fire resistant.
BUR is created by layering asphalt and ply sheets over top of your roof insulation and deck. This creates a water-resistant, stable roof – able to hold heavy equipment, like HVAC systems, even when the roof is covered in snow.
Modified bitumen roof
Modified bitumen roofing (MBR) is another popular asphalt-based commercial flat roofing system. It’s a two-part system made up of a base layer and cap layer, and it can be made using either Styrene-Butadiene-Styrene (SBS) or Atactic Polypropylene (APP) – the “rubber” and “plastic” asphalts, respectively.
MBR comes in a wide variety of different styles, it’s easy to install, and it’s cost effective. Like BUR, MBR is weather resistant and fire resistant. MBR is also UV resistant, and parts of the roofing system are recyclable.
PVC roof
PVC roofing is a single-ply, plastic roofing solution. It’s an incredibly strong and durable commercial roofing solution. It can hold a lot of weight, and it’s resistant to heat, inclement weather, and even harsh chemicals.
This roofing system is also recyclable, adding an environmental benefit.
