The Science Behind Green RoofsPosted by Etta Brookover on Sep 30, 2015 in Science | Comments Off on The Science Behind Green Roofs
Well, most of you can probably already figure out that Green Roofs are some sort on environment friendly roofs. Well, that’s right, but you’d never guess what’s the science behind it. There are many companies out there that deal with this, and the people of the Columbus Roofing in Ohio, a company that deal with reviving roofs, decided to tell us all about these types of roof and how they work.
Well, these green roofs are a type of a vegetated rooftop that is especially designed to help the people avoid the problems that usually occur in urban areas; problems such as elevated air temperatures, air and water pollution, and flooding. These roofs can intercept storm water, that usually goes right into the gutters, and reduce the flooding in urban areas. These roofs have some kind of plants inside them, and these plants are responsible in capturing the carbon and cleaning the air. Also, these roofs are great because they help to reduce the usage of energy, and help out with the maintaining of the urban heat islands. These green roofs are also great because they can provided a habitat for some wild animals and birds, and it can even be used to produce food!
Even though this technology is still in development, people believe that eventually it will be extremely popular, because of the fact that there are so many positive sides to it, and so little negative ones.
There are several basic types of green roofs. The first ones are called “extensive”, and they do not require much maintenance, and have shallow soils that are perfect for plants that are low-growing, such as Sedum. Then, there are “intensive roofs”, which are green roofs that practically include a whole garden on your house. They can maintain a wide range of plants that could be planted there, but they need a lot more maintenance than the first ones. People say that you can even plant trees in them!
Then, there are “modular” and “monolithic” ones. The “Monolithic” green roofs are the types of roofs where you have several layers of soil, and in which the roots can grow anywhere they please. On the other hand, the “monolithic” ones are made out of several containers, so the roots of one plant cannot intermingle with another.
It should be noted that the soil used in these types of roofs is not your usual everyday soil. It is a special kind of soil full of minerals. Also, they are quite different because they are extremely low in organic matter, and this type of soil was proven to be the best by laboratories in Europe. Now, this is nothing new, since this thing was pioneered way back in the ’70s, but the people are only now starting to realize its potential.
