Why Do All Commercial Buildings Have Flat Roofs?

If you’re fond of taking long walks through the city or often walk through downtown, you might have noticed that most commercial buildings are shaped differently than residential ones. For starters, they are wide, and secondly, commercial buildings have a flat roof on top rather than typical shingles. But what exactly is the purpose behind flat commercial roofs? Are they really that better than traditional roofing options? To find the answers to your questions and more, make sure to keep on reading.

What Are Flat Commercial Roofs?

A flat commercial roof is a special roof level that is often built into commercial buildings. This means that rather than the slope appearance, these roofs have a straight surface with little to no pitch.

It is important to note that sloped roofs serve the purpose of redirecting rainwater out of your home. However, with commercial buildings, that isn’t a big concern. This is because flat roofs have their own system of gutters and drainage where the water never gathers but instead finds a way to flow out itself.

Why Do Commercial Buildings Have Flat Roofs?

Most commercial buildings stick to a simple, clean look with flat roofs to support the uniform structure. This helps save additional costs and cuts down on maintenance time. However, there are also other reasons for a flat roof, some of which are mentioned below.

1. HVAC Unit Storage: Commercial buildings house a lot of different departments inside, which have their own HVAC systems. Flat roofs are perfect for storing the big HVAC units, so it doesn’t take up extra space inside the building and can be safe from acts of vandalism.

2.Long-Lasting: Flat roofs are typically made of asphalt, which is not only an affordable material but also long-lasting and durable. Asphalt flat roofs can last for as long as 50 years without the need for constant maintenance and care.

3. Low Maintenance Cost: Given its simple surface, flat roofs are far from expensive when it comes to roof maintenance. They are incredibly easy to care for, especially because you have open access to the roof. Moreover, due to the flat surface, you can walk on it and quickly fix any issue there may be.

4. No Gutter Installation: Rather than traditional gutter lines that run along the length of the roof, commercial buildings have their own intricate system. This means that there is no need for a gutter installation or regular gutter cleanings.

5. Cost-Effective: Since there are no shingles or additional components needed to enhance the roof’s appearance, commercial building owners save a lot of money on its construction.

6. Energy Efficient: Flat roofs, paired with damage-resistant flooring, can help fight against harmful UV rays. This keeps the interior of the building cool and protected while canceling out energy costs.

7. Easy Installation: Due to their formation, flat commercial roofs do not take as much time or planning during installation. They are uncomplicated to build, which makes them great for building owners looking to maintain the time during construction.
