How Many Types of Commercial Roofing, and Which One is Best?

November 1, 2022

Does your commercial roof need repair, or are you considering getting a new one? Each commercial roof type has its own set of advantages, and making a decision is tricky due to the variety of options available. When selecting a roof, one needs to take into account several factors. These include the roof’s lifespan, typical weather variations, and energy efficiency.

Durability, energy efficiency, and cost are three factors to consider when purchasing a new commercial roof. Commercial roofing systems can last anywhere from a decade to over 50 years if properly installed and maintained. These estimates may vary greatly depending on climate and roof conditions. Read further to learn more about the types of commercial roofing materials.

Types of Commercial Roofing

There are many types of commercial roofing which have their advantages. 

  • Green Roofing
  • Thermoset Roof Membrane
  • Metal Roofing
  • Thermoplastic Roof Membrane
  • Modified Bitumen Roofing
  • Built-Up Roofing Membrane

Green Roofing

As a genuinely sustainable roof option, green roofs are the most versatile kind of commercial roof available today. They have not only become more popular in recent years, but they are also very versatile. This sustainable masterpiece consists of a tough waterproof membrane covered by green plants. These sustainable masterpieces improve air quality and often add a green oasis for employees to relax and unwind.

Thermoset Roof Membrane

Thermoset roof systems are incredibly durable and versatile. Roofs for commercial buildings are constructed with Ethylene Propylene Diene Terpolymer (EPDM) membranes. EPDM roofing offers high resistance to ultraviolet light and ozone. It is made of single-ply rubber material, making it an excellent choice for reducing energy costs. 

Metal Roofing

Metal roofing is a very popular type of commercial roof due to the variety of metal materials available. These are some of the most common metal roofing materials used for commercial roofing:

  • Aluminum
  • Corrugated Galvanized Steel
  • Aluminum, Zinc, and Tin
  • Coated or Stainless Steel
  • Copper
  • Tile sheets

Metal roofing has many benefits, including its attractive appearance, fire resistance ratings, and strength and sustainability.

Thermoplastic Roof Membrane 

Commercial roofs of thermoplastic Polyolefin (TPO) and Polyvinyl Chloride (PVC) are lightweight, highly reflective, and weather-resistant. As well as being UV-resistant and tear-resistant, they are resistant to bacterial growth and most chemicals, including oil and animal fats. 

Modified Bitumen Roofing

Using modified bitumen on your commercial building roof may be a good idea if you expect a lot of activity. In a similar manner to Built-Up Roofing membranes, reinforced roof fabrics serve as carriers for bitumen, which is then cut and installed in layers. These commercial roofs are generally fastened to roof decks for maximum stability and protection as two-ply systems.

Built-Up Roofing Membrane

The Built-Up Roof, or “BUR,” is made by alternating layers of gravel and tar and has a lifespan of 20 years or more. The number of layers determines the durability and (ultimately) cost. An inexpensive and easy-to-repair roof, it’s one of the oldest and most flexible roof types. Although seamless roofing holds up well to foot traffic, it relies on its stable understructure to handle weight and vibrations. Moreover, it can be coated to reflect heat and is UV-resistant.


Consider your options if you need a new roof for your commercial property or are considering various commercial roofing materials for new construction. Do you have a visible roof, one you walk on, one that gets grease, acid, or chemicals on it, one that gets a lot of sunlight, a lot of wind, or one that gets extremely cold?

Your choices SHOULD be influenced by the climate and the type of building. Take into account the roof’s lifespan and maintenance cost. Do not forget to consider the energy costs of different types and colours of roofing. Dark roofs may reduce heating bills in cold weather, while white roofs may reduce air conditioning costs in warm weather.
