Roofs serve as the first line of defense against environmental hazards, be it extreme weather conditions, UV rays, or other external factors. While residential roofs are designed with a focus on aesthetics and durability, commercial roofing systems have different requirements and considerations. They need to be robust, long-lasting, and must cater to the unique needs of commercial buildings. This article will delve deep into the intricacies of commercial roofing, its types, and essential factors to consider.

Roofs serve as the first line of defense against environmental hazards, be it extreme weather conditions, UV rays, or other external factors. While residential roofs are designed with a focus on aesthetics and durability, commercial roofing systems have different requirements and considerations. They need to be robust, long-lasting, and must cater to the unique needs of commercial buildings. This article will delve deep into the intricacies of commercial roofing, its types, and essential factors to consider.
1. What Constitutes a Commercial Roofing System?
Unlike their residential counterparts, commercial roofs are typically flat or have a low slope. This design choice often relates to the building’s size – it’s more feasible and cost-effective to have flat roofs for large commercial buildings. However, this also means commercial roofs need specialized materials and systems to ensure water drainage and durability.
2. Types of Commercial Roofing Systems
Several types of commercial roofing systems cater to different needs and budgets:
Built-Up Roofing (BUR): This is the traditional tar-and-gravel roof and consists of multiple layers for added protection. BUR is known for its durability and waterproofing capabilities.
Metal Roofing: While more common in residential settings, metal roofs are also an option for commercial buildings. They’re durable, resistant to extreme weather conditions, and come in various styles and finishes.
Modified Bitumen Roofing: This is an evolution of BUR but uses reinforced roof fabrics that act as “carriers” for bitumen, which is then applied to the roofing surface. It offers better flexibility and weather resistance.
