Why Flat Roofs Dominate the Commercial Building Landscape


The Economics of Flat Roofs

When it comes to commercial buildings, flat roofs are often the go-to choice for architects and builders alike. One of the primary reasons is cost-effectiveness. Flat roofs require less material and labor compared to their A-frame counterparts, making them a financially savvy option. This is especially crucial for businesses looking to maximize their investment in building infrastructure.

Maximizing Utility Space

Flat roofs offer unparalleled utility space for various mechanical equipment, including HVAC systems. This is a significant advantage for commercial buildings, where large, integrated HVAC units are commonly placed on the roof. The flat surface also facilitates the installation of other systems like plumbing vents and cooking hoods, making it a versatile choice for diverse commercial needs.

Maintenance: A Double-Edged Sword

While flat roofs offer easier and safer access for maintenance, they also come with their own set of challenges. For instance, water ponding can become a serious issue if regular inspections are not conducted. However, with a professional approach to maintenance, these challenges can be easily managed. This is where companies like Equity Roofing come into play, offering specialized Central PA roofing services to ensure your flat roof stays in optimal condition.

Types of Flat Commercial Roofs

Modified Bitumen

Modified Bitumen roofs, although less common today, were once a staple in commercial roofing. Comprising asphalt and polymerized rubber, these roofs were known for their weather resistance but have largely fallen out of favor.


EPDM (Ethylene Propylene Diene Monomer) is a synthetic rubber material known for its longevity and high-temperature resistance. However, it is less resistant to chemicals and UV radiation, making it a less popular choice in recent times.


TPO (Thermoplastic Olefin) roofs are lauded for their high reflectivity, which aids in reducing cooling costs. They are also durable and resistant to punctures, making them a preferred choice among Central Pennsylvania roofing contractors.


PVC (Polyvinyl Chloride) is considered the highest quality material for flat commercial roofs. Known for its durability, flexibility, and extreme weather resistance, PVC is often recommended by roofing companies in Central PA for those who can afford it.
