Commercial roofing systems come in several types, each suited to specific needs and building characteristics. TPO (Thermoplastic Olefin) is a popular choice for flat or low-slope roofs, offering energy efficiency, UV resistance, and ease of installation. EPDM (Ethylene Propylene Diene Monomer) is a durable, rubber-based roofing material known for its long lifespan and resistance to extreme temperatures, making it ideal for commercial buildings in diverse climates. Modified Bitumen combines the flexibility of asphalt with added layers of protection, making it suitable for both low-slope and flat roofs in commercial buildings. Built-Up Roofing (BUR), which layers asphalt or Coal tar pitch and reinforcing materials, is highly durable and commonly used in areas with harsh weather or heavy foot traffic. Each system is selected based on factors like climate, budget, and the building’s functional requirements.
| Feature | TPO | EPDM | PVC | MODIFIED |
|---|---|---|---|---|
| Material | Thermoplastic, polypropylene-based | Synthetic rubber (ethylene propylene) | Plastic-based, vinyl blend | Asphalt-based, modified with polymers |
| Color Options | White, light-colored | Black (mostly), some white White, | light-colored | Multiple |
| Energy Efficiency | High (reflective, reduces cooling costs) | Moderate (absorbs heat, good for colder climates) | Very high (reflective, reduces cooling costs) | Moderate (reflective coatings available) |
| Durability | Good (but can degrade over time) | Very good (20-30 years) | Excellent (30+ years) | Good puncture and tear resistance, but seams can fail |
| Puncture Resistance | Moderate | High | High | High |
| Maintenance | Moderate (vulnerable to damage) | Low (resistant to punctures, UV) | Low (resistant to chemicals, UV) | Moderate (regular inspections needed) |
| Installation Cost | Moderate | Moderate | High Moderate to Low | |
| Chemical Resistance | Moderate | Low | Excellent (high chemical resistance) | Moderate |
| Climate Suitability | Best for warm climates | Suitable for cold climates | Best for industrial and high-chemical environments | Suitable for cold climates |
| Environmental Impact | Generally considered eco-friendly | Low impact | Higher impact (production & disposal concerns) | Poor (asphalt-based, not as recyclable) |
