Let’s lead with the advantages of a flat roof. For many commercial architects, these pros are a given, but for all you homeowners out there curious about the style, perhaps taking note of the advantages can help you make a more informed decision.


Architects tend to love a flat roof. The clean, horizontal line emphasizes and contrasts the vertical space around the home or building – the trees, neighouring houses, skyline, etc. – leaving a lasting impression. The roofing style is also closely associated with minimalism: an aesthetic that emphasizes the functional features of a home, rather than its flashier design elements.
In the GTA, you’ll see a lot more new houses built with flat roofing, sometimes even between very old, pitched roof houses. The effect, we think, looks pretty cool. We love seeing a diversity of houses in and around the city.

Outdoor Space

Of course, there’s more to a flat roof than its looks. It can also be functional. A popular use for flat roofs is as an outdoor space. With a few seats up on the roof, you’ve got an al fresco view of your surroundings that you simply can’t get with a pitched roof. It essentially adds another, fresh-air floor to your home!

Cost to Build

Because the surface area is smaller, the cost of materials for a flat roof is less than that of its pitched counterpart. The catch here is that you want experienced, trustworthy professionals building your flat roof; a poorly constructed flat roof can lead to further maintenance and repairs in the future, potentially offsetting the construction savings.
