The energy crisis of the 1970’s drove the roofing industry to create new products to meet revised efficiency guidelines. It was this period of innovation that saw the invention of modified bitumen roofing alternatives. We are seeing a similar trend now. Roofing manufacturers, power companies, government agencies, and environmental organizations are collaborating on new ways to conserve energy.
Perhaps the most creative of these are vegetative roofing and photovoltaic technologies. However, without government intervention by way of incentives, these are not likely to see a large market share for at least a decade. We are seeing some municipalities pushing for vegetative systems since they are energy efficient as well as reduce water runoff to sewer systems. For the most part, these will still remain “on the edge” technologies. Far more likely to see rapid adoption are cool roofing technologies.
