Green Roof Reno

Oh . . . the Possibilities!
When we dream . . . we dream green. Lately it as though we wake up and imagine weekend mornings with [iced] coffee and the Times on the roof deck surrounded by greenery and the city and the sky. We definitely want to be eco-conscious in this project but we also want it to be affordable and comfortable . . .Hopefully, these ideas go hand in hand.
We realize, of course, that green roofs have been done before. In fact, Europe and especially Germany can be considered leaders in the field with 35 to 40 years of tested green roof installations. Projects in the States can be found burgeoning in every major city. We hope to be one small piece of the puzzle; contributing our part to the greater ecological challenge we face as a country.
Approaching the Co-Op
Right now, we are in the process of putting together a package to present to our co-op board. We’re definitely anxious about getting over this hurdle as things seem to always be tricky when dealing with co-op boards. . .
We’ll present this project for what it is; a private space for us, but also a benefit to the long term health of the building. Green roofs have lots of benefits, from savings on heating and cooling costs to increasing the life of your current roofing system by two to three times. Other positives of installing green roof systems include the city-wide effects of stormwater retention and the mitigation of the urban heat island effect. The new New York City PlaNYC [www.nyc.gov/2030] from Bloomberg proposes a 35 percent tax benefits for green roof construction costs. We hope to figure out how to take advantage of this!
To clarify, we own the roof rights to the space directly above our apartment (essentially half the roof space). We will pay for the installation of the roof deck and green roof on the portion of the roof we own. As part of our package for the Co-op we might include options like offering to green our neighbors’ roof space at the same time per their expense or the co-op’s . . . That would of course be an ideal situation because it would unify the design of the project while providing a maximum benefit for our investment. We will also present a proposal for a structural analysis that will determine whether an extensive green roof and deck is even possible. With steel or without, we are confident we will be able to create something beautiful.
Green Roof Images
These images inspire us – we’re thinking architectural, sleek, with defined edges . . . plantings in masses that change in color throughout the seasons.

Green Roof Plants
You can get green roof plants from a ton of places and we’re going to explore a bunch of them, ordering samples and giving reviews. The plant options for a green roof are literally through the roof – there are zillions of choices and the hard part is choosing the right plant for the right climate and site. The manner in which they are delivered is also varied; being offered by companies as mats, blocks, carpets, tiles, grids, modules, and paks. We’ll have a lot of choices to make to make in the next few months . . .

Looking forward to seeing your progress. Seems like a great idea for all the reasons you've mentioned in addition to the added enjoyment.
One question - is the other half of the room a common space for the rest of the coop members?

well, if you're looking to building a space for you to have a table, shelter on HALF than that is going to be pretty much all deck with some landscaping. so it seems to be the "green roof" is going on the common area. and yeah, I'm not sure if I'd sign off on that if I were on the board.

Well, don't expect small building coop boards to see what is in their best interest. Mine preferred to spend way more on heating oil every year than to fix things to make our heating more efficient. They also couldn't care less about things related to conservation - self-interest ruled.
And, as to prolonging the roof's life, depending on the condition of the roof right now, it might actually shorten it (weight + use could, on an old unstable roof.) You might need to offer to redo the roof first - easy if it's just a rubber roof coating, but way expensive (probably prohibitively so) if it involves what's underneath the many layers of roof you may already have on there. See what the structural analysis says - I'd have started with that.

Check this out:
That's ours. Pretty home-made, but it might give you some ideas.

Best of luck!

Oh, also check out Gaia soil for green roofs. It's made of recycled styrofoam peanuts mixed with compost. One of the few media made of recycled materials. Doubly green! I plan to go with that when I add more modules to my green roof this Spring.
