When considering a “green roof,” or a roof that is environmentally friendly, you ought to take two main things into consideration: the specific material, and the color.
Since your roofing material is the final layer of protection from the outdoor elements and from indoor heat loss, it’s arguably the most important structure in all of your home. When asking the question “is it green? Consider:
When looking at various materials, you aren’t going to come across one specific substance that out performs all the other substances in these categories. Some other better than others, in different regards. For instance, clay has a vary natural manufacturing process, but maintenance is difficult, where as some metals tend to be made through a process that harms the environemt, but they tend to be extremely durable.
It’s a simple fact of science that light colors reflect heat, while darker colors absorb it. With that said, the color roof you choose, will really all depend on the climate in which you live. We’re not asking you to completely reject style though – choose a color that will be energy efficient, yet still blend will the the design of the rest of your home.
