Understanding the Different Types of Commercial Flat Roofing Systems

Did you know that the global flat roofing systems market is expected to reach $66.23 billion by 2027?

Flat roofs are a common feature in commercial buildings. They offer a cost-effective and space-efficient solution for large structures.

However, not all flat roofs are created equal. There are several types of commercial flat roofs. Each with its unique features and benefits.

In this article, we will explore the different types of commercial flat roofing systems. Read on to help you understand which one is best suited for your building.

Built-Up Roofing (BUR)

Built-up roofing, also known as tar and gravel roofing, has been in use for over a century. It consists of multiple layers of bitumen and fabric reinforcement. It’s topped with a layer of gravel or mineral aggregate.

They bond the layers together with hot asphalt and typically have a lifespan of 20-30 years. BUR is durable and can withstand heavy foot traffic.

However, it is prone to leaks and requires regular maintenance. It also tends to be heavier than other roofing options. This may require additional structural support for the building.

Modified Bitumen Roofing (MBR)

Modified bitumen roofing is a modern version of BUR. It’s made from asphalt and rubber modifiers. This makes it more flexible and resistant to extreme temperatures.

The installation process involves torching or hot-mopping the sheets together. MBR can last up to 20 years and has a higher resistance to leaks compared to BUR.

It also comes in various colors and finishes. This provides more design options for commercial buildings.

Ethylene Propylene Diene Terpolymer (EPDM) Roofing

EPDM roofing is a popular choice for commercial buildings. It’s a synthetic rubber material that is cost-effective and easy to install.

EPDM is lightweight, making it suitable for any building structure. It also has excellent resistance to UV rays, punctures, and tears.

This roofing system can last up to 25 years and requires minimal maintenance. Its black surface also helps with energy efficiency. It can absorb heat during the winter months.

Thermoplastic Polyolefin (TPO) Roofing

TPO roofing is a newer type of flat roofing system that has gained popularity in recent years. It’s made from a combination of ethylene-propylene rubber and polypropylene.

TPO is highly reflective, making it energy-efficient. It can help reduce cooling costs. It’s also resistant to UV rays, tears, and punctures.

This roofing system is lightweight, easy to install, and requires minimal maintenance. It has a lifespan of 20-30 years. Roofing experts recommend TPO for buildings in areas with high temperatures and UV exposure.

Green Roofing Systems

Green roofs are becoming increasingly popular in commercial buildings. This is due to their sustainable benefits. They consist of a layer of vegetation and soil on top of a waterproof membrane.

Green roofs help reduce the urban heat island effect. It also improves air quality and provides insulation for the building. They also have a longer lifespan compared to other flat roofing systems.

However, green roofs require more maintenance. They may not be suitable for all buildings due to the added weight.

Polyvinyl Chloride (PVC) Roofing

PVC roofing is another popular choice for commercial flat roofs. This type of roofing system is made from a durable, synthetic plastic polymer. It provides excellent resistance to chemicals, fire, and punctures.

PVC roofing is also known for its energy efficiency due to its high solar reflectivity. This can help reduce cooling costs.

Additionally, it offers a long lifespan of 20-30 years and requires minimal maintenance. The flexibility of PVC makes it easy to install, even on roofs with complex designs.

Spray Polyurethane Foam (SPF) Roofing

Spray Polyurethane Foam roofing is a unique and versatile roofing system. It involves spraying a liquid foam onto the roof. This then expands and hardens into a solid layer.

SPF roofing provides excellent insulation, reducing energy costs for heating and cooling. It is also lightweight and can be applied over existing roof systems. This eliminates the need for a full roof replacement.

The seamless nature of SPF roofing reduces the likelihood of leaks and requires minimal maintenance. With proper care, this roofing system can last up to 30 years.

Metal Roofing Systems

Metal roofing has been used on commercial buildings for decades. It offers a durable and long-lasting solution. Metal roofs can be made from various materials such as steel, aluminum, and copper.

They have excellent resistance to harsh weather conditions and require minimal maintenance. However, they can be noisy during heavy rain or hailstorms.

Metal roofing systems also come in different styles, allowing for versatility in design options. They can last up to 50 years with proper maintenance.

Self-Adhered Roofing Systems

Self-adhered roofing systems have gained traction in the commercial sector. This is due to their ease of installation and reliability.

These systems typically feature a peel-and-stick membrane. They can be applied directly onto the roof substrate. This minimizes the need for special tools or adhesives.

They are often made from rubberized asphalt or a mixture of polymers. They provide excellent water resistance and flexibility.

Silicone Roofing

Silicone roofing systems are gaining traction due to their superior waterproofing and UV resistance. These systems involve applying a silicone coating to the existing roof surface. This creates a seamless, durable barrier against water and environmental elements.

Silicone roofs are known for their ability to withstand ponding water. This makes them ideal for flat or low-slope roofs. The reflective properties of silicone also contribute to energy efficiency by reducing heat buildup.
