Most commercial roofs are either low slope or flat, which narrows down the available roofing materials. The eight most common options include the following:

It is a popular commercial roof type with several different metal materials available, including the following:

Built-up roofing, commonly known as the BUR roof, is the standard tar-and-gravel roof built with multiple piles or layers. It is a low-slope roof system that is durable and cost-effective. You can choose to add several layers to this flexible commercial roofing system as per your durability requirements and budget.

It is similar to the BUR roofs with reinforced roof fabrics cut and installed in layers. This commercial roofing system is typically fastened to the rooftops as two-ply systems to ensure protection and maximum stability. Modified bitumen roofs require low maintenance, often only needing and annual inspection and cleaning. Mod bit roofs provide improved tensile strength compared to other flat roofs and are an ideal choice if you expect regular foot traffic or anticipate increased activities on the building roof.

A thermoset roof system, also known as EPDM roofing, offers versatility and long-lasting durability. It is simple to install and low maintenance as compared to other commercial roofing systems. The EPDM roof membrane is made from a single-ply rubber material and resistant to acids, solvents, alcohol, and ultraviolet light. It is flexible in colder temperatures and has reflective properties to reduce cooling costs.

Polyvinyl Chloride (PVC) and Thermoplastic Polyolefin (TPO) roofing systems are reflective, lightweight, and offer resistance to UV light, tears and punctures, weathering, chemicals, bacteria, oils, and animal fats. It has improved seam strength, which makes it ideal for second-generation applications as well. This makes TPO roofs a popular choice for restaurants, hotels, and businesses that emit oils from their vents.

Although it is mostly used on residential buildings, shingle roofing is also an excellent option for commercial properties, especially for steep rooflines. Shingles are available in several materials such as ceramic, asphalt, slate, plastic, and more. They are affordable, easy to install, and versatile. However, it is crucial to ensure they are of high quality to ensure durability. If this type of roof requires repair, it is best to hire an experienced contractor who can provide a reliable solution without compromising the integrity of the entire roofing system.

SPF or Spray Polyurethane Foam is a commercial roofing material that expands into foam from a liquid spray and hardens into a solid layer. SPF roofing is long-lasting with correct installation, annual inspections, and upkeep. It can be applied on the existing roof and is an eco-friendly option that has been around since the early 1960s. It adds to the insulation, is waterproof, and can be used in different climates.

Green roofs are environmentally-friendly and the most versatile commercial roofing option. They have become popular recently due to their aesthetically pleasing look and sustainability. They are ideal for businesses and commercial properties. Green roofing systems can protect your building from the elements while improving energy efficiency and managing drainage and water.

If your commercial property needs a new roof, it helps to think about what might be right for you. It is best to consider the durability, energy efficiency and cost of the roof. Correctly installed and maintained commercial roof systems can last over 50 years depending on usage, foot traffic, climate conditions, and other factors. Although cost is a critical aspect, ensure that you do not compromise on the quality by choosing a less expensive roof system.
