I need to get to some decision about the roof - soon. The solar panel decision would require a new roof. It strikes me that I still haven't got a good idea of how much it would cost to go green.
The pros are, I assume:
- I need to replace the roof anyway
- A green roof will help insulate for both extremes: heat and chill
- I like the thought of having a green roof
- I was thinking of getting more substance anyway (the current roof looks so skimpy)
The questions are:
- Will the roof structure be able to carry the green roof?
- What is the real cost of a complete installation with correct drainage, irrigation and plant material? I have read estimates around $15-25 per sf for extensive roofs, and if all my 3000 sf roof area should be covered it would be $60K. That's a lot!!!! And it doesn't include the waterproof membrane - which I believe will easily cost $10-15K
I need some real numbers!
