When it comes to protecting your commercial building, the roofing system you choose is one of the most important investments. Low-slope roofs — common in warehouses, retail spaces, and office complexes — require materials that can stand up to weather, foot traffic, and long-term performance.
Below, we break down some of the most common options, with a focus on the newer, high-performing membranes that are reshaping the industry.
Traditional Roofing Options
Built-Up Roofing (BUR)
• What it is: Layers of asphalt and reinforcing fabric, finished with gravel or cap sheets.
• Pros: Time-tested, durable, excellent UV protection.
• Cons: Heavy, labor-intensive installation, can be difficult to repair.
EPDM (Ethylene Propylene Diene Monomer)
What it is: A synthetic rubber membrane, typically black, used widely on commercial roofs.
Pros:
• Proven track record with decades of use.
• Flexible and durable in a variety of climates.
• Cost-effective, especially for large roofs.
Cons
• Black surface absorbs heat (higher cooling costs).
• Seams are glued/taped, not heat-welded → weaker than TPO/PVC seams.
Newer Single-Ply Membrane Options
TPO (Thermoplastic Polyolefin)
What it is: A single-ply, white reflective membrane.
Pros:
• Highly reflective → reduces cooling costs.
• Heat-welded seams → strong and watertight.
• Lightweight and easy to install.
Cons:
• Performance varies by manufacturer (quality matters).
• Not as long of a track record as older materials.
Best for: Businesses looking for energy efficiency and a balance of performance and cost.
PVC (Polyvinyl Chloride)
What it is: A flexible single-ply membrane with plasticizers for added durability.
Pros
• Superior chemical and grease resistance (great for restaurants or industrial buildings).
• Strong, heat-welded seams.
• Long proven track record.
Cons
• Slightly higher upfront cost than TPO.
• Can shrink over time if not properly installed.
Best for: Facilities that need chemical resistance or proven long-term performance.
TPO vs. PVC — Quick Comparison
TPO
- Energy Efficiency: Excellent
- Seams: Heat Welded
- Chemical Resistance: Moderate
- Cost: Very cost efficient
- Track Record: ~30 years
PVC
- Energy Efficiency: Excellent
- Seams: Heat Welded
- Chemical Resistance: High (great for oils/grease)
- Cost: Cost efficient, but higher upfront comparatively to TPO
- Track Record: ~50 years
Our Take
At Executive Roofing, we recommend TPO for most clients who want a cost-effective, energy-saving solution. For restaurants, factories, or facilities exposed to chemicals, PVC remains the gold standard.
No matter the choice, our team ensures expert installation — because even the best material is only as good as the crew that installs it.
