What Is The Best Flat Roof Material?

Although not as common as traditional roofs in Calgary, homeowners can experience a wealth of flexible materials and advantages for homeowners when investing in flat roofing in Calgary

 

Yet, many homeowners are confused about which material they should opt for when installing their flat roofs. 

 

In today’s blog post, we’ll focus on the best materials for your flat roof. But we get to that, let us tell you about the benefits of getting a flat roof in the first place. 

 

Benefits of a Flat Roof 

 

Although it is often considered more for commercial properties, flat roofs are an excellent choice for many homeowners due to their array of benefits. 

 

If installed correctly by a professional Calgary roofing company, you can experience the following advantages: 

  • Low-level maintenance 
  • Unique and straightforward design
  • Improves curb and aesthetic appeal
  • Long-lasting endurance and durability
  • Watertight and protective system 

 

However, flat roofs can’t be applied to all homes. You will need a slope of 2:12 or less to get it installed unless you wish to start from scratch. 

 

If you are convinced about the benefits of a flat roof or realize that your roof’s slope is at 2:12 or less, it’s time to invest in a flat roof. 

 

While there are plenty of materials available, it can be difficult to narrow down the best choices for your home. So, we did the hard work for you.

The Best Materials For Your Flat Roof  

 

Built-Up Roof Membrane (also known as BUR) 

The classic hot-tar-and-gravel flat roofing approach. The application includes three or more piles of waterproof membrane that are alternated with hot tar before a layer of smooth stone to ensure it is secure and tight. Fibreglass membranes can also be used during the construction. 

 

Perks of Built-Up Roof Membrane in Calgary: 

  • An excellent fire-resistant material
  • Durable and strong layer
  • Aesthetically appealing and attractive for homeowners
  • Enhances curb appeal
  • Economical friendly option 

 

Modified Bitumen Roof 

Another popular option for homeowners, modified bitumen roofs are similar to BUR roofs in which there are multiple piles. 

Waterproofing flat roof with bitumen sealing membranes

The only difference is the materials used: they are composed of polymer modified bitumen material, either atactic polypropylene (APP) or styrene butadiene styrene (SBS). It can be installed in various application methods, including cold and hot-applied, torch (heat) applied, self-adhered or mechanically fastened. 

 

Perks of a Modified Bitumen Roof in Calgary: 

  • It can be installed by homeowners (but we don’t suggest it) 
  • Seamless connections making installation easier 
  • Leak and tear resistance 
  • UV and heat resistance, and environmentally friendly
  • Various style options 

 

Rubber Membrane Roof (also known as EPDM) 

Part of the single-ply family (including Neoprene, PVC, and Polymer-modified bitumens), EPDM (short for ethylene propylene diene monomer) is a true rubber material and the most popular choice for residential properties. Its membrane material is durable, and its single-ply system makes the installation simple and effective, as it can be applied with fasteners, ballasted or glue.

 

Perks of a Rubber Membrane Roof in Calgary: 

  • Simple and effective installation 
  • Longest lifespan; approximately up to 25-30 years
  • Lightweight and flexible, yet durable, material 
  • Resistance to wind, hail, UV and extreme temperatures
