First make sure your structure is strong enough to SUPPORT a green roof. They can weigh upwards of several times as much as a conventional shingled roof, and need MUCH more in the way of posts/beams/rafters.

They have a demonstrated track record in reducing temperatures of buildings in hot climates, but do *not* tend to do much to keep buildings warm in cold winters (alas for me :p)

Also unless you plant entirely with hen-and-chicks and selected sedums, it will not be green for most of the year, it will be more along the lines of a brown roof ;)

If you want to build one, definitely read some books on the subject. There are a lot of construction considerations, and it sounds like little changes in design can really make the difference between a basically-successful roof and one that leaks or collapses or slumps off the edge.

Good luck, have fun,

Pat

Thanks Pat. :)

It will be a very small green roof, probably about 3 1/2 x 3 1/2, because my existing coop has a very small foot print ;) .

Our weather is mild year round.

At our county fair the Master Gardeners always put in a show garden. They include a green roof along with instructions. This is particularly geared to our area and the Master Gardeners are there to answer questions. I have found it to be very interesting.

I have bought several drought and or heat tolerant plants from them for our front yard. Often these are the same plants they put on the green roof. They also had a rainbarrel set up with it for the runoff that would still occur in our rainy winter months.

the Ford Plant in Detroit has a green roof- we were able to see it when we went on a trip to the Henry Ford Museum and Greenfield Village.

It was planted in sedum. I thought it was fascinating and it seemed to do a good job for them. they also had special perforated parking lot materials and some other interesting projects. That was several years ago- I was so hoping they were going to position themselves as a progressive green company, but doesn't seem to be so much.

Maybe I missed it, but is your coop high enough that the chickens won't be able to get up on it? I hope your project works- I wonder if there would be anything edible that could be planted on it? Maybe some drought resistant herb?

Yeah, no I didn't say how high up my coop is. The roof would be about 6 feet high when it is finished. They couldn't get up there.

I would love to plant different things during different times of year. I thought kale, spinach and lettuce would work in the spring and fall. I haven't thought about summer yet. Herbs? The roof would be small and low enough to "garden" by standing on a step stool.
