Popular Commercial Roofing Types
TPO Roofing
Thermoplastic Olefin (TPO) is a single-ply roofing membrane that has gained popularity due to its energy efficiency and cost-effectiveness. TPO roofs are known for their reflective properties, which can significantly reduce cooling costs by reflecting UV rays. This can be particularly beneficial in Southern California, where summer temperatures often soar.
In terms of cost, TPO roofing generally ranges from $5.50 to $9.50 per square foot, including installation. This makes it a more affordable option compared to other commercial roofing types. Additionally, TPO membranes offer excellent resistance to ozone, algae, and chemical exposure, making them ideal for various commercial applications.
One of the notable advantages of TPO is its durability, which can span over 20 years with proper maintenance. Regular inspections and timely repairs can extend this lifespan even further. For insights on maintaining your roof, consider reading our seasonal roof maintenance checklist.
EPDM Roofing
Ethylene Propylene Diene Monomer (EPDM) is a durable rubber roofing membrane widely used in commercial settings. Known for its long-lasting properties and flexibility, EPDM can withstand extreme weather conditions, making it a reliable choice for businesses in the San Gabriel Valley.
EPDM roofing costs typically range from $6.50 to $11.00 per square foot. Although slightly more expensive than TPO, its resilience and versatility justify the investment, especially in regions prone to varying weather patterns. EPDM is also environmentally friendly, as it can be recycled and repurposed at the end of its life cycle.
One of the key benefits of EPDM roofing is its simple installation process, which can help reduce labor costs. However, it’s essential to work with experienced professionals to avoid common pitfalls. Learn more about the cost factors associated with roof repair and installation.
Modified Bitumen Roofing
Modified bitumen roofing is an asphalt-based system suitable for commercial buildings requiring a robust and weather-resistant solution. It consists of multiple layers that enhance strength and durability, making it an excellent choice for flat and low-slope roofs.
The cost of installing modified bitumen roofing typically ranges from $4.00 to $8.00 per square foot. Its multilayer design offers superior protection against harsh weather conditions, including heavy rain and strong winds, common in Southern California’s climate.
Maintenance is crucial for preserving the integrity of modified bitumen roofs. Regular inspections and timely repairs can prevent minor issues from escalating into significant problems. For affordable repair services, explore our guide on what to expect from roof repair services.

Factors to Consider When Choosing a Commercial Roof
Climate Considerations
When selecting a commercial roofing type, it’s important to consider your local climate. Southern California’s climate, characterized by hot summers and mild winters, requires roofing materials that can withstand intense heat and provide energy efficiency. Reflective options like TPO and cool roofing systems can help reduce energy costs by minimizing heat absorption.
During the rainy season, it’s crucial to have a roof that prevents leaks and withstands moisture. Modified bitumen and EPDM are excellent choices due to their waterproof properties. For more information on roofing materials that prevent leaks, check out our detailed guide.
Additionally, consider wind resistance when selecting a roofing system. Some materials, like metal and modified bitumen, offer superior resistance to strong winds, ensuring your business remains secure even during adverse weather conditions.
Budget and Cost Factors
Understanding the cost implications of different commercial roofing types is essential for making an informed decision. Budget constraints often dictate the choice of materials and installation methods. Below is a table comparing the average costs of popular commercial roofing systems:
| Roofing Type | Cost Range (per sq. ft.) | Average Lifespan |
|---|---|---|
| TPO | $5.50 – $9.50 | 20+ years |
| EPDM | $6.50 – $11.00 | 25 – 30 years |
| Modified Bitumen | $4.00 – $8.00 | 15 – 20 years |
It’s also important to factor in long-term maintenance costs. While some materials may have a higher upfront cost, their durability and low maintenance requirements can lead to cost savings over time. For a detailed breakdown of roof repair costs, visit our comprehensive guide.
