Choosing the right roofing system for your commercial building is critical. Not only does it protect your property from the elements, but it also enhances your building’s aesthetic appeal and can even reduce energy costs. In this blog post, we will explore six popular roofing options for commercial buildings, providing insights into their benefits, drawbacks, and ideal applications. Whether you’re a business owner, property manager, or architect, you’ll find valuable information to help you make an informed decision.
Built-Up Roofing (BUR)
Built-Up Roofing, commonly known as BUR, is one of the oldest and most reliable commercial roofing systems. This type of roof is created by layering multiple plies of roofing felt and asphalt, which are then topped with a layer of gravel or mineral granules. This construction technique provides excellent durability and resistance to heavy foot traffic.
One of the primary advantages of BUR is its proven track record. With over a century of use, BUR systems have consistently demonstrated their ability to withstand harsh weather conditions and last up to 20 years or more. Additionally, the multiple layers make BUR highly resistant to leaks, ensuring your building remains dry and secure.
However, there are some downsides to consider. BUR roofs are heavy and may require additional structural support, which can add to the overall cost. Installation can also be labor-intensive and time-consuming, making it less suitable for projects with tight deadlines. Despite these challenges, BUR remains a popular choice for commercial buildings due to its durability and reliability.
Modified Bitumen
Modified Bitumen roofing systems are an evolution of the traditional BUR, designed to offer enhanced flexibility and ease of installation. These roofs consist of layers of asphalt combined with polymerized rubber or plastic, which are then reinforced with fiberglass or polyester. The result is a durable, flexible, and weather-resistant roofing material.
One of the key benefits of Modified Bitumen is its ability to expand and contract with temperature changes, reducing the risk of cracks and leaks. This makes it an excellent choice for buildings in areas with extreme temperature fluctuations. Additionally, Modified Bitumen is relatively easy to install, often requiring only a torch or cold adhesive.
Despite its advantages, Modified Bitumen does have some limitations. It can be susceptible to damage from foot traffic and sharp objects, so it may not be the best choice for roofs that require frequent maintenance access. Additionally, while it is more flexible than traditional BUR, it may not offer the same level of long-term durability. Nonetheless, Modified Bitumen remains a popular choice for many commercial applications due to its flexibility and ease of installation.
Metal Roofing
Metal roofing systems are increasingly popular for commercial buildings due to their durability, energy efficiency, and low maintenance requirements. These roofs are typically made from steel, aluminum, or copper, and can be coated with various finishes to enhance their appearance and performance.
One of the most significant advantages of metal roofing is its longevity. With proper installation and maintenance, metal roofs can last 40 to 70 years or more, making them a cost-effective long-term solution. One popular choice among property owners is TAMKO’s line of metal shingles, known for their aesthetic appeal and robust performance.

Additionally, metal roofs are highly resistant to fire, wind, and impact damage, providing excellent protection against extreme weather conditions.
Energy efficiency is another key benefit of metal roofing. Reflective coatings can help reduce heat absorption, lowering cooling costs during hot summer months. However, metal roofs can be noisy during heavy rain or hail, and they may require additional insulation to mitigate this issue. Despite these minor drawbacks, metal roofing remains an attractive option for many commercial building owners due to its durability and energy-saving potential.
Thermoplastic Olefin (TPO)
Thermoplastic Olefin (TPO) roofing systems are a popular choice for commercial buildings due to their energy efficiency, durability, and ease of installation. TPO membranes are made from a blend of polypropylene and ethylene-propylene rubber, which are reinforced with polyester or fiberglass.
One of the primary benefits of TPO roofing is its energy efficiency. The white reflective surface of TPO membranes helps reduce heat absorption, lowering cooling costs and extending the life of HVAC systems. Additionally, TPO is highly resistant to UV radiation, chemicals, and punctures, making it a durable and low-maintenance option.
TPO roofing is also relatively easy to install, with options for both fully adhered and mechanically attached systems. However, it’s essential to ensure proper installation and quality materials, as some TPO products have been known to experience issues with seam integrity and membrane shrinkage. Despite these concerns, TPO remains a popular choice for commercial buildings due to its energy efficiency and overall performance.
Ethylene Propylene Diene Monomer (EPDM)
Ethylene Propylene Diene Monomer (EPDM) is a synthetic rubber roofing membrane that has been widely used in commercial applications for over 50 years. Known for its durability, flexibility, and resistance to extreme weather conditions, EPDM is an excellent choice for many commercial buildings.
One of the main advantages of EPDM roofing is its ability to withstand temperature extremes, making it ideal for buildings in regions with harsh climates. The membrane is also highly resistant to UV radiation, ozone, and chemical exposure, ensuring long-lasting performance with minimal maintenance. Additionally, EPDM is available in large sheets, reducing the number of seams and potential leak points.
While EPDM offers many benefits, there are some drawbacks to consider. The black color of the membrane can absorb heat, leading to higher cooling costs in warmer climates. However, white EPDM options are available to address this issue. Installation can also be labor-intensive, requiring specialized equipment and expertise. Despite these challenges, EPDM remains a popular choice for commercial roofing due to its durability and versatility.
Green Roofing
Green roofing systems, also known as living roofs, are an innovative and environmentally friendly option for commercial buildings. These roofs consist of a multi-layered system that includes a waterproof membrane, drainage layer, growing medium, and vegetation. Green roofs offer numerous benefits, including improved energy efficiency, stormwater management, and enhanced aesthetics.
One of the most significant advantages of green roofing is its ability to reduce energy consumption. The vegetation layer helps insulate the building, keeping it cooler in the summer and warmer in the winter. This can lead to substantial savings on heating and cooling costs. Additionally, green roofs help manage stormwater runoff by absorbing and filtering rainwater, reducing the strain on municipal drainage systems.
Green roofs also provide numerous environmental benefits, such as improving air quality, supporting biodiversity, and reducing the urban heat island effect. However, green roofing systems can be more expensive to install and maintain compared to traditional roofing options. They require specialized expertise and ongoing care to ensure the health of the vegetation. Despite these challenges, green roofs are an attractive option for commercial building owners looking to promote sustainability and create a visually appealing rooftop space.
Selecting the right roofing system for your commercial building is crucial for ensuring long-term durability, energy efficiency, and overall performance. Each of the six options discussed in this blog post—Built-Up Roofing, Modified Bitumen, Metal Roofing, Thermoplastic Olefin, Ethylene Propylene Diene Monomer, and Green Roofing—offers unique benefits and considerations. By understanding the strengths and weaknesses of each option, you can make an informed decision that best meets the needs of your building and organization.
