Yes, white TPO (Thermoplastic Polyolefin) roofs are significantly more energy efficient than traditional dark-surfaced roofing systems like torch-on (modified bitumen).

According to the provided content, TPO roofs offer high energy efficiency due to several factors:

• High Reflectivity: The white membrane is designed to reflect sunlight rather than absorbing it. This reflective top layer helps reduce heat absorption on sun-exposed roofs.
• Reduced Cooling Costs: By reflecting solar radiation, TPO systems can effectively cut summer cooling costs for commercial buildings, providing a practical financial benefit for property managers in the Lower Mainland.
• Environmental Impact: Because TPO is energy-saving and fully recyclable, it helps reduce a building’s overall carbon footprint.

In contrast, torch-on roofing typically has low energy efficiency because its dark surfaces absorb heat, though they can sometimes be modified with specific coatings to improve performance.
