When it comes to constructing or renovating a commercial property, choosing the right type of roof is crucial. The roof not only protects the building from external elements but also plays a significant role in energy efficiency and aesthetics. With a myriad of options available, it can be overwhelming to determine which type of roof is best suited for your specific needs.
In this article, a leading commercial roofing company in Atlanta explores various types of commercial building roofs, discussing their advantages, disadvantages, and ideal applications. Whether you’re looking for durability, cost-effectiveness, or environmental sustainability, we’ve got you covered. Let’s dive in and find the perfect roof for your commercial property!

Flat roofs are a popular choice for commercial buildings due to their cost-effectiveness and versatility. These roofs are characterized by their low slope, making them ideal for accommodating HVAC systems, solar panels, and other equipment. Flat roofs are commonly constructed with materials such as built-up roofing (BUR), modified bitumen, or single-ply membranes like EPDM (ethylene propylene diene monomer) or TPO (thermoplastic olefin). They offer easy access for maintenance and repairs, and their simplicity makes installation relatively quick. However, flat roofs require regular inspections and maintenance to prevent water pooling, which can lead to leaks and other problems.
Metal roofs have gained popularity in commercial construction due to their durability, longevity, and aesthetic appeal. Typically made from steel, aluminum, or copper, these roofs offer excellent resistance to fire, high winds, and impact, making them suitable for buildings located in areas prone to severe weather conditions. Metal roofs are lightweight, reducing the structural load on the building, and they can be installed quickly. Additionally, they are energy-efficient and can be coated with reflective finishes to enhance their thermal performance. However, metal roofs can be more expensive upfront, and without proper insulation, they may generate more noise during heavy rain or hailstorms.
Green roofs, also known as living roofs or rooftop gardens, have become increasingly popular in commercial building design due to their environmental benefits and aesthetic appeal. These roofs are covered with a layer of vegetation, providing insulation, reducing stormwater runoff, and improving air quality. Green roofs can reduce energy consumption by insulating the building and mitigating the urban heat island effect. They also provide additional outdoor space for employees or visitors to relax and enjoy nature. However, green roofs require specialized design and installation, as well as ongoing maintenance to ensure proper drainage, irrigation, and plant care. They may also require structural modifications to support the additional weight of the vegetation.
Built-Up Roofs (BUR)
Built-up roofs (BUR), also referred to as tar and gravel roofs, have been a popular choice for commercial buildings for many years. BUR roofs consist of multiple layers of bitumen and reinforcing fabrics, creating a durable and waterproof membrane. They are resistant to UV rays and provide excellent protection against water infiltration. BUR roofs offer good fire resistance and can withstand foot traffic. However, they can be heavy and require regular maintenance to prevent damage and extend their lifespan. BUR roofs may also have higher installation costs compared to other roofing systems.
Single-Ply Membrane Roofs
Single-ply membrane roofs are a versatile and cost-effective option for commercial buildings. These roofs consist of a single layer of synthetic materials, such as EPDM, TPO, or PVC (polyvinyl chloride). Single-ply membranes offer excellent resistance to UV radiation, chemicals, and punctures. They are lightweight and can be installed quickly, reducing labor costs. These roofs require minimal maintenance and are often energy-efficient, allowing for potential energy savings. However, single-ply membranes may be more prone to damage from foot traffic or sharp objects, and they may have a shorter lifespan compared to some other roofing materials.
When choosing the best type of roof for your commercial building, it is essential to consider the specific needs of your project. Factors such as climate, building design, budget, and long-term maintenance should all be taken into account. Consulting with a professional roofing contractor or architect can help you make an informed decision and ensure that your commercial building is equipped with the most suitable roof for its requirements.
There are several types of roofs available for commercial buildings, each with its advantages and considerations. Flat roofs offer versatility and accessibility, metal roofs provide durability and energy efficiency, green roofs offer environmental benefits and aesthetic appeal, built-up roofs provide excellent protection against water infiltration, and single-ply membranes offer cost-effectiveness and easy installation.
By carefully evaluating your needs and consulting experts in the field, you can make an informed decision and select the roof type that best suits your commercial building. Remember that investing in a high-quality roof is essential for the long-term protection, energy efficiency, and functionality of your commercial property.
