Eco Brooklyn installs different kinds of green roofs but the basic technology is always the same: to replicate a normal soil environment in a very shallow depth and a harsh environment.
The basic components are plants, growing medium and then an assortment of water retention, drainage, root barrier and soil retention. This can be one layer or a bunch of layers.
We love doing slanted roofs and usually build our own soil retention structures but the general idea is like the image below.
Here are the basic steps:
Installing a green roof is really cool and pretty simple. The problem is that you are high up in the air on the main barrier between the building and rain. So lots of things can also go wrong. As a green roof installer we have learned a lot and thankfully haven’t screwed up too badly. Despite the fact that we are constantly pushing the barrier. Our latest installation involved a river on a roof. Pretty cool.
