I finished my very simple green roof design. I went very low-budget on it since it is a goat barn, and I am curious if we can get away with it.
First I sliced some 2-inch tubing open and clamped it on the side of the roof, for the plastic and fabric to go over and under. I had to cut it into short segments, as it wasn’t very flexible. The round shape of the tube will prevent the water from crawling back up to the bottom of the roof. Or at least, that’s the theory.
Next, I covered the milled pine boards with cardboard (part recycled, part purchased), in order to protect the plastic, and then covered the cardboard with plastic that is used for greenhouses. Once the plastic was on I took off my shoes and covered the plastic with thin fabric (as I said, I went low budget). I also added 3 logs over the fabric, secured from the side with metal wiring. These are supposed to keep the soil in place while the roof gets established, since I imagine they will rot over time. Next I added gravel along the logs, and a thin layer of soil over the entire roof. I covered the soil with moss collected from our land, and I intend to add some wildflower seeds as well. I still need to install the skylight and finish covering that part of the roof.
The cobbing has also progressed quite a lot. We are pushing to finish the barn before Tal’s sister comes in April, so that she can warm up the space for the goats.
We have added the windows (old refrigerator shelves, so it’s safety glass), and threw in a few bottles as well. This way we can get some pratice with burying glass in cob and creating arched windows, and make more informed decisions for our future house.
