In the article “The Concrete Advantage” from Green Rooftop website, Green Rooftops claims that hydrophobic technology removes hazardous factors for users while assuring monetary returns. Concrete green roofs are sturdy and do not degrade over time. The article states that the use of waterproof concrete has helped to defeat the greatest disadvantage of green roofs by removing the element found most speculative by handlers. Builder's job is made easier since there is no use of membranes, eliminating the detriments in the build-up. The task can be accomplished quicker as there is no concrete-cure waiting time before inclusion of the membrane, resulting in cost-effectiveness for the user. Root barriers are unnecessary as growth of roots are eradicated with the use of waterproof concrete. The article also mentions that in the case where maintenance is needed on the green roof, a simple inoculation of polyurethane grout can be induced at the bottom, minimizing any harm towards the ecosystem.
Base on the points elaborated by the author, I support the use of concrete green roofs as they are more reliable compared to the traditional roofing system. Usage of concrete green roofs not only allows the user to overcome the disadvantages of a traditional system, but it also helps in the preservation of the ecosystem.
