Commercial Flat Roofing: TPO, EPDM, and PVC

For commercial property owners in the Midwest, your roof is one of the most critical components of the building. It protects employees, customers, and valuable assets while also helping control energy costs.

Unlike residential homes, many commercial properties use flat or low-slope roofing systems that require specialized materials. At JB West, we install high-performing TPO, EPDM, and PVC roofing systems designed to meet the demands of commercial buildings.

Why Flat Roofing Matters for Commercial Buildings

Commercial roofs face unique challenges compared to residential systems. They often cover larger surface areas, support HVAC units, and must handle standing water or drainage differently.

Choosing the right roofing system can make the difference between decades of reliable performance and costly repairs down the road. That’s why many businesses turn to TPO, EPDM, and PVC — three of the most trusted flat roofing materials in the industry.

TPO Roofing

Thermoplastic Polyolefin (TPO) is one of the most popular commercial roofing materials today. TPO membranes are white, reflective, and energy-efficient, making them ideal for businesses that want to reduce cooling costs during hot Midwest summers.

Key Benefits of TPO Roofing:

• Energy Savings – Reflects sunlight, lowering building temperatures.
• Durability – Resists punctures, tears, and UV damage.
• Low Maintenance – Requires minimal upkeep compared to older flat roofing systems.
• Cost-Effective – Provides excellent performance at an affordable price point.

For retail stores, office buildings, and warehouses, TPO delivers both efficiency and long-term value.

EPDM Roofing

Ethylene Propylene Diene Monomer (EPDM) is a synthetic rubber roofing material known for its flexibility and resilience. Often referred to as a “rubber roof,” EPDM has been used in commercial roofing for decades.

Key Benefits of EPDM Roofing:

• Proven Longevity – Can last 30 years or more with proper maintenance.
• Weather Resistance – Performs well in both hot and cold climates, handling Indiana’s seasonal swings.
• Flexibility – Expands and contracts without cracking, ideal for fluctuating temperatures.
• Ease of Repair – Damage can often be patched without replacing large sections.

EPDM is a great option for warehouses, manufacturing facilities, and other large flat-roof buildings.

PVC Roofing

Polyvinyl Chloride (PVC) is a durable, single-ply roofing membrane often used on restaurants, factories, and buildings where chemical resistance is important. Its heat-welded seams provide excellent waterproofing.

Key Benefits of PVC Roofing:

• Chemical Resistance – Withstands exposure to grease, oils, and industrial byproducts.
• Strong Seams – Heat-welded seams create a watertight bond, reducing leaks.
• Durability – Resists fire, wind, and water intrusion.
• Energy Efficiency – Reflective surfaces help control cooling costs.

PVC is a trusted choice for businesses that need both durability and specialized performance.

Comparing TPO, EPDM, and PVC

Each roofing system has its strengths. TPO is known for energy savings, EPDM for flexibility and long life, and PVC for its strength and chemical resistance. At JB West, our experts help commercial property owners determine the best option based on budget, building type, and environmental demands.

Installing a commercial flat roof requires expertise and precision. JB West follows a proven process to ensure every system is installed for maximum performance:
