What is Flat Roofing?

Flat roofs are a term used to describe a roof with a flat or nearly flat pitch – typically anywhere from a 1/2″ to 1/4″ per square foot. This low slope still allows water to drain to one side of the roof and into a gutter system, but the relative flatness provides businesses and commercial properties with benefits that range from improved energy efficiency to industry-specific accommodations like additional rooftop-mounted equipment, walkways for maintenance personnel, and more. Flat roofs are standard for commercial roofing in the United States, and the various types and styles of flat roof systems enable property owners to choose a purpose-built design for their unique business needs.  

Tailored Roofing Systems Typically Found on Commercial Buildings

One of the primary reasons that flat roofing is the preferred style of roofing for commercial buildings is the variety of systems and designs that are available. Nearly every aspect of a flat roof, from the materials used to roof deck construction and more, can be adjusted and tailored for the needs of a specific business or property! Whether you need a rooftop green space for improved environmental efficiency, or a roof purposely built to handle the weight of heavy-duty specialized equipment, flat roofing systems allow you to design and build the best roofs for your particular needs. 

What are Some Common Materials for Flat Roofs?

One of the most important choices you can make when it comes to flat roofing is the type of material to build your roof from. There are a few primary types of roofing materials used for commercial properties, and each comes with their own set of advantages and disadvantages. If you’re torn between which flat roofing style to invest in for your business, take the time to understand these pros and cons so you can make an informed decision. 

Built-Up Roofing (BUR)

Built-up roofing systems were first designed and used in the 1800s, but they saw their true rise in popularity during the 1970s. Since then, BUR has become one of the dominant roofing systems in commercial America, and for good reason.

Built-up roofing is comprised of several interlocking layers of bitumen (which can include cold tar, asphalt, or another adhesive) and hot asphalt or fiberglass. These layers are then covered with a surface aggregate for improved durability and aesthetic enhancements.

This layered system produces a roof that is incredibly durable, resistant to water, and heavy winds, and energy efficient. On the downside, these roofing systems have more seams, which creates more opportunity for leaks. And their life expectancy varies from 10 to 20 years, depending on the installation method.

Rubber Roofing Membranes (EPDM, TPO, PVC)

The term “rubber roofing” encompasses several varieties of flat roof designs. Also known as “single-ply membranes,” the most common types of rubber roofing are: 

• EPDM (Ethylene Propylene Diene Monomer) Roofing 

• TPO (Thermoplastic Polyolefin) Roofing 

• PVC (Polyvinyl Chloride) Roofing 

All of these rubber roofing materials are durable, water resistant, and offer more energy efficiency than BUR roofing; each also has its own unique advantages and disadvantages. 


• EPDM roofing is highly durable and is great for Maryland weather, making it a long-lasting roofing option.

• EPDM roofs are cost-effective, offering a lower installation and maintenance cost compared to other roofing materials.


• TPO roofing is highly UV resistant, which can improve its lifespan and keep environmental costs low. 

• TPO is among the most popular roofing systems because of its life span of 20 to 30 years. It’s easily maintained, offers outstanding durability, and is the go-to roofing system for both residential and commercial flat roofs.


• PVC roofing is recyclable, resistant to fire and extreme winds, and can last for more than twenty years with regular maintenance.  

• PVC roofing is highly durable, with a lifespan of 20–30 years or more, making it a long-term roofing solution. They also require minimal maintenance and are easy to clean, saving time and money on upkeep..

Metal Roofing

Metal roofing offers best-in-class durability and longevity compared to other commercial roofing styles. Some metal roofs have been known to last more than seventy years, and other perks include increased impact resistance, rust resistance, and durability against extreme weather. Metal roofs are also often made from recycled material and can be recycled themselves at the end of their lifespan; combined with their ability to reflect UV rays and lower environmental costs, metal roofing is incredibly environmentally friendly and a sustainable investment for eco-conscious businesses.
