Green Roof for Coop and Cement Board

[cukooformarans]

I am about to build a coop and really love the idea of a green roof. In the interest of using what we have on hand, I was wondering if concrete board would make an acceptable base. (We have a little left over from a tiling project.) Y'all be gentle if this is a dumb question- I know nothing about construction and can't find anything that specifically addresses this question on this site or online.

I'm unsure of what a concrete board is. Do you have a picture?
I would think that would add a lot of weight to the roof.
On a green roof do you add soil for the plants? That would add weight too. You wouldn't want it to collapse onto your birds...

This is a link to the product. It is heavy, so we would definitely have to support it well. But I thought it may hold up to moisture and the weight of the bed better than plywood. Of course, we would also have to install a moisture barrier. From what I understand, people typically use a mixture of soil and lighter weight materials for the growing medium, but it is still heavy.

just reading the Q/A on the linked page doesn't sound too promising.

Hmmm. I didn't think to look at the questions, I don't know why because I looked everywhere else. I think you are probably right. Thanks.

There is a wide range information online for making a green roof. I just googled green shed roof

Thank you! Yes, I have found a lot of information but not the answer to that specific question. (Until Krugerrand pointed it out.)

No reason to be sorry! Thank you for your input!
