When it comes to commercial roofing, single-ply roofing systems are a top choice for their durability, versatility, and cost-effectiveness. Among the most popular options are TPO (Thermoplastic Olefin), EPDM (Ethylene Propylene Diene Monomer), and PVC (Polyvinyl Chloride). Each system has unique strengths and weaknesses, making the “best” choice dependent on your building’s needs, budget, and environmental conditions.

Single-ply Roofing System Comparison
TPO: The Rising Star of Single-Ply Roofing
TPO is a relatively newer single-ply membrane that has quickly gained popularity for its energy efficiency and affordability. Made from a blend of polypropylene and ethylene-propylene rubber, TPO is a flexible, lightweight option for commercial flat roofs.
Key Advantages:
- Energy Efficiency: TPO’s white reflective surface meets ENERGY STAR® standards, reducing cooling costs by deflecting UV rays.
- Cost-Effective: TPO is often less expensive than PVC while offering similar energy benefits.
- Durability: Resistant to punctures, tears, and chemical exposure, TPO performs well in moderate climates.
The First Class Roofing Difference
- 15+ years relevant expertise
- Solid company reputation
- Professional treatment
- Quality workmanship
- Non-prorated warranties
Potential Drawbacks:
- Quality Variability: The rapid growth of TPO roofing has led to inconsistencies in material quality across manufacturers.
- Seam Weakness: TPO seams are heat-welded, which requires skilled installation to ensure long-term performance.
Best For:
Buildings in regions with moderate climates looking for an affordable and energy-efficient option.
EPDM: The Industry Veteran
EPDM is one of the oldest and most trusted single-ply roofing systems. This synthetic rubber membrane is renowned for its flexibility, making it a popular choice for commercial roofs with irregular shapes or frequent temperature fluctuations.
Key Advantages:
- Proven Longevity: With over 50 years of performance history, EPDM roofs can last 20–30 years with proper maintenance.
- Weather Resistance: EPDM excels in extreme temperatures, from freezing cold to scorching heat.
- Ease of Installation: Available in large sheets, EPDM minimizes seams, reducing potential leak points.
Potential Drawbacks:
- Limited Reflectivity: Standard EPDM membranes are black, absorbing heat and raising cooling costs. Reflective coatings can be added, but at an additional expense.
- Chemical Vulnerability: EPDM is less resistant to oils and certain chemicals, which may be a concern for industrial buildings.
Best For:
Buildings in regions with harsh weather or temperature extremes, especially those prioritizing durability over energy efficiency.
PVC: The High-Performance Option
PVC roofing is known for its superior performance in durability and energy efficiency. Made from flexible polyvinyl chloride, PVC membranes are reinforced with polyester or fiberglass for added strength.
Key Advantages:
- Durability: PVC is highly resistant to fire, chemicals, and grease, making it ideal for industrial or restaurant roofs.
- Energy Efficiency: Like TPO, PVC membranes are highly reflective, reducing cooling costs and contributing to sustainability goals.
- Seam Strength: Heat-welded seams create a watertight seal, enhancing the roof’s longevity.
Potential Drawbacks:
- Higher Cost: PVC is generally more expensive than TPO and EPDM, which may be a drawback for budget-conscious projects.
- Environmental Concerns: PVC production has a larger environmental footprint compared to other membranes, which may not align with certain sustainability goals.
Best For:
Buildings requiring exceptional chemical and fire resistance, such as manufacturing facilities and restaurants.
