Flat roofs are the most common type of roofing used on commercial buildings. It can be made from different materials and has a lot of benefits for commercial properties. It is crucial to know about flat roofs if you intend to install one on your building. 

Why Do Commercial Buildings Have Flat Roofs?

Flat roofs offer a few advantages for businesses over traditional sloped roofs often seen in residential construction.

  • Cost

The major reason flat roofs are installed on industrial buildings is the cost. Flat roofs are often less expensive to install compared to sloping roofs because of their less surface area, allowing businesses to keep construction costs down.

  • HVAC Considerations

The positioning of air conditioning units is another reason why many business buildings have flat roofs. When a roof has a low slope, company owners can keep air conditioning units on the roof rather than on the ground. This structure protects HVAC devices from damage and vandalism and eliminates the need to send cold air upwards, which may consume a lot of energy.

  • Flat Is a Misnomer

Although commercial building roofs seem level from the ground, they actually have a little slope, often around 2%, just enough for water to flow either to the center into a drain hole or the edge. Related: Best Flat Roof Benefits in Orange County

Most Common Commercial Building Flat Roof Types

The most common commercial building flat roof types are

  • Built-Up Roofing Systems (BURs)

This roofing material is reasonably priced and is a fantastic choice for industrial buildings. It uses many layers of industrial-grade cloth, felt, or paper coated with hot asphalt or coal tar for waterproofing.

  • Modified Built-Up Roofing

This roofing comprises many layers of asphalt and polymers and is an excellent alternative for constructing a weathertight design for your business structure.

  • Single-Ply Roofing

This alternative is likewise low-cost and long-lasting. It often employs waterproof membranes composed of EPDM, PVC, or TPO. Since they can reflect up to 85 percent of the sun's rays, they may also help keep energy bills low. Also read: Common Problems With Flat Roofs and Tips for Fixing Them

Advantages of Commercial Flat Roof

      • The biggest advantage of a flat roof is the low cost. They are relatively cheaper than other roofs.
      • The second advantage is that a flat roof’s surface area can be used for other purposes. Air conditioning units can be put on the roof instead of on the ground.
      • Flat roofs are typically more accessible than sloped roofs. They are easier and safer to climb upon to inspect as they are substantially more stable than slanted roofs.
