Looking into Flat Roof Decking in Calgary

Understanding Flat Roof Decking

Have you ever been to areas around the city where their rooftops are turned into a certain space? For example, restaurants with patios at the top of their roof. If so, that’s a result of the flat roof decking. 

Flat roof decking isn’t limited to public spaces’ rooftops – some homes can have them too!

You see flat roof decking commonly at penthouses since they’re typically connected to the rooftop. However, houses can have them as well if they have a flat roof. From flat roof decking, it constructs an outdoor space into whatever the person wishes it to be.

Naturally, when flat roof decking is done, it’s finished off with fencing for safety reasons.

The Benefits of Flat Roof Decking

Flat roof decking comes with various benefits. Namely, one of the biggest is how you can transform the rooftop to suit you. 

Do you like entertaining and socialising with friends but don’t have patio space down below? Instead, turn your rooftop into a patio! Many friends and family will love the novelty of its location. Plus, you can bet that it can provide you and everyone with outstanding views. And with summertime celebrations, you can bet you will get a clear view of fireworks that erupt into the sky!

If you happen to have more of a green thumb, you can easily turn your rooftop into a garden paradise. There is enough room that you can grow various plants and vegetables without worrying if they’re getting enough sun or not. It gives them all the sun exposure they need to thrive. 

Beyond turning the rooftop space to your liking, there are other benefits such as:

  • Fire resistance with high-quality thermal performance. 
  • Provides your roofing system sound & structural support.
  • Creates a slope for improved wind-uplift performance & a slope for drainage.
  • Increase the value of your home by giving personality.

Therefore, when it comes time to replace your flat roofing in Calgary, it makes sense that you would want the best materials available. But is there a true standout when it comes to flat roofing materials? Let’s explore your options below.

The Pros and Cons of Flat Roofing Materials

Built-Up Roof (BUR)

This is your traditional hot-tar-and-gravel roofing option. With three, if not more, layers of waterproof membrane alternating with hot tar, you’re sure to have a reliable, leak-proof roof. 

This type of flat roofing is attractive, fire-retardant, and relatively inexpensive. The main drawback to this style is the installation process: it’s smelly, heavy, and requires a true pro to ensure a proper finish.

Modified Bitumen Roof

This single-ply roofing material is infused with a mineral-based wear surface. It comes in a roll, and as you unroll it, a torch is used to heat and adhere the material to the surface of the roof. That said, there are peel-and-stick options available now, which can be safer to install.

This type of flat roofing can be perfect for those looking to save money in the long run, as its light-coloured mineral surface is able to reflect heat and cut down those energy bills. However, the installation process does present a fire risk, and it’s not as scuff-resistant as other options.

Rubber Membrane Roof

This material may resemble an inner tube, but its durability and resistance to damage and sunlight prove it’s here to stay! Rubber roofs can be anchored with fasteners, glue, or ballasted with stone.

This material is fairly light, yet can still hold up against scuffs and tears. Additionally, if leaks ever form, they are relatively simple to patch. The main downside to this option is the cost; the standard black material absorbs heat, thus increasing your energy bill, while the lighter-coloured options generally cost more, thus impacting the price of your roof replacement.

Final Verdict

Ultimately, there is no one material that can be described as being the best. Take your time to research your options and connect with a contractor to determine which flat roofing material would make the most sense for your property.

When you begin to notice unexplained cases of mould, water stains, condensation, or even leaks, you know it’s time to replace your flat roof. While the varying types of flat roofs may be similar in appearance, they each have their own pros and cons.

Let’s take a look at some of the types of flat roofs available to you and how they can work to protect your property.

3 Types of Flat Roofs

  1. Built-up Roof (BUR)

This is the traditional hot tar and gravel roof that is comprised of three (sometimes more) plies of waterproof material, which alternate with hot tar. While they once used tar paper, it’s more common to find roofing companies using more advanced materials, such as fibreglass membranes.

The most attractive fact about this particular flat roof is that it is generally the least expensive option. Gravel is also fire-resistant, which is an added bonus.

On the other hand, this is a rather heavy material that is smelly and messy to install. Therefore, it’s recommended a professional is hired to install the roof and that the building not be occupied during the installation.

  1. Modified Bitumen Roof

This is a single-ply roof that has a mineral-based surface. During installation, modified bitumen roofing is rolled out and then heated with a torch to ensure proper adhesion. However, there are peel-and-stick options coming out as well, which can be safer to work with.

This type of roof is moderately priced, but more expensive than BUR. However, the mineral surface creates a lighter colour, thus reflecting the sun and reducing energy bills. Therefore, you may find yourself making back some of that initial investment through savings.

  1. Rubber Membrane Roof 

This is another single-ply material that tends to resemble the feel of an inner tube. Rubber membrane roofing can be anchored with either fasteners, glue, or stone.

This type of roofing is easy enough to install that property owners could do it themselves if they so wished. The material is highly resistant to scuffs and tears, and any leaks that may appear in this roofing are easy to patch. 

It is, however, the most expensive option and more susceptible to punctures.

If you’re considering flat roofing in Calgary but are unsure of where to start, don’t hesitate to reach out to a professional roofing company. With their years of experience, they’ll be able to advise you on which flat roof makes the most sense for your property.
