Cool roofs improve roof durability and reduce both building cooling loads & the city heat island effect.

Cool roofs are successful alternative to mass loft insulation under roofs in damp tropical and subtropical climates. Mass insulation can be entirely replaced by roofing systems that together replicate solar radiation and provide release to the sky.

San Antonio Cool roof can be used as a geo-engineering technique to deal with global warming based on the theory of solar radiation management, provided that the materials used not only reflect solar energy, but also produce infra-red radiation to cool the planet.
