Why do most commercial buildings have flat roofs?

Although the vast majority of residential roofs are sloped, you rarely see sloped roofs on businesses. The slope on a roof helps to prevent leaks, because it prevents water from just sitting on the roof and eventually soaking into it. But if flat roofs are so prone to leaks, why do you find them on almost all commercial buildings? There are actually a number of benefits associated with flat roofs for businesses. Here is a list of just a few of them from our commercial roofing experts in Hilton Head:

#1. Flat roofs are more affordable.

When compared to sloped roofs, flat roofs take less skill and time to install, which also means that they are much more cost effective to install than sloped roofs. In areas with little to no snow, like here in Hilton Head, the need for a slope is much less than in areas that get lots of heavy snow that can weigh down roofs. Many homeowners still have sloped roofs in these little-to-no-snow areas, but this is because sloped roofs are more aesthetically pleasing. But businesses have to save every penny they can, and many are far more interested in function than they are in form.

#2. Flat roofs allow for more storage.

Businesses need every square foot they can get around their property for parking, signage, etc., and they don’t have a lot of room to store equipment and machinery, like air conditioning units, around their building. Flat roofs help to add more usable square footage to commercial properties, and they make ideal areas to store air conditioning units, vents, heating units and other equipment. Flat roofs are also easier to access than sloped roofs, which is another reason why storage is ideal on flat roofs. Additionally, all of that machinery can be noisy, and putting it on the roof helps to minimize the noise that customers and clients are exposed to.

#3. Flat roofs are ideal for larger buildings.

It’s fair to assume that most commercial buildings are larger than most residential homes, particularly the ones that are likely to utilize flat roofs, and when it comes to roof pitch, the size of the building can make a huge difference. A sloped roof on a large, commercial building would have to feature either several valleys and peaks or an extremely tall peak, neither of which is ideal, or cheap. Additionally, commercial buildings have to follow municipal height restrictions that make sloped roofs an impossibility for larger buildings.

As you can see, flat roofs can be beneficial for businesses in a variety of ways. And although they are called “flat” roofs, it doesn’t necessarily mean that all flat roofs are completely flat. The roofs may look like they’re completely flat, particularly from the ground, but most have a slight slope, which is typically about two percent. This helps to minimize water accumulation and prevent leaks.
