This study presents a multi-criteria methodology for evaluating the energy and environmental performance of cool, green, and traditional roofs. The increasing adoption of energy-efficient building materials has highlighted the need to compare different roofing systems for their effectiveness in reducing energy consumption, mitigating urban heat island effects, and improving environmental sustainability. The proposed methodology integrates key performance indicators such as thermal performance, energy savings, stormwater management, air quality improvement, and biodiversity enhancement. By applying this approach, the study analyzes the life cycle impact of each roof type, providing a comprehensive comparison.

The results indicate that while cool roofs excel in thermal management, green roofs contribute significantly to ecosystem services. Traditional roofs, though still widely used, offer limited benefits in comparison. This methodology serves as a tool for urban planners and architects to select appropriate roofing systems based on specific environmental goals and energy demands.
