Why Do Commercial Buildings Have Flat Roofs?

If you visit a commercial district and look around, chances are you’ll notice a sea of flat roofs. If you wonder why most commercial buildings have flat roofs, read on—we explain what makes flat roofs such a popular choice for businesses.

What are Flat Roofs?

Before we get into the benefits of flat roofs, it’s important to clarify what a flat roof is. A common misconception is that flat roofs are 100% flat, but this isn’t the case. “Flat” roofs look flat at first glance, but they actually have a 2 percent slope that permits water to drain toward the middle or off the sides of the roof.

Why Flat Roofs?

So, why do commercial buildings have flat roofs? There are several reasons commercial buildings utilize these low-slope systems. Here are just a few:

Low Cost

Flat roofs are cost-effective because they have less surface area and are easier to install since contractors can safely walk across them. Most owners of large commercial buildings worry less about curb appeal and more about their bottom line, which makes this cost-friendly roof type popular.

Easily Host HVAC Units

Because these roofs have a low slope, you can house HVAC units on top of them. This saves space on ground level and protects these units from vandalism.

Reduce Energy Costs

Flat roofs are also remarkably eco-friendly. You can coat them with white, reflective material to reflect UV-rays and keep the building cool, which reduces the need for A/C. Additionally, you plant greenery on top of flat roofs, turning them into sustainable gardens that protect the roof by absorbing water and sun.

No Gutters

Gutters are the bane of home and business owners globally, as cleaning them is time-consuming and unsafe. Flat roofs don’t have gutters because they don’t need them; they use roll-off systems to keep water and debris off.
