Green Rooftop

Here is a link to "G-Sky", a green roofing manufacturer and contractor. We may do this on our rear add-on rooftop. The current roof is simple asphalt roll-paper, with some technical issues. The roofing paper itself is new, and under warranty, however according to our home inspector, it is an inappropriate design for the extremely flat pitch of the roof. However, that very same flat pitch is perfect for a green roof!

I like G-Sky's design system, as it seems ideal for residential applications. There are only a few layers to put down, and the soil system is thin and light. Seeing as how the house will be run completely on electric power, the added benefit of the green roof should help with energy costs.

There is also a plumbing junction right there in the upper story bathroom, so an irrigation outlet could be run straight from the bathroom.

We may have to build up an edge around the roof to contain the various underlayment and the soil, and I'm not sure who we'd have to contact about the current structural load-bearing capacities but we'll need those numbers to decide if the current roof will be strong enough to withstand the weight of the green roof.

Do-it-yourself would be nice. We also need to talk to the town hall to see what kind of permits are necessary... we might have to put the bid together for the side balcony with the rear green roof.
