How much does it cost for a green roof on a house?

The answer will depend on what you mean by 'green'. If you mean green, as in the color, then the cost will vary according to the quality and type of materials you wish to use, and the square footage of the roof itself. If you mean green as in environmentally friendly, then the costs there will also vary. You should budget a bare minimum of $5,000.00 for the roofing material alone, labor and other expenses will add to this. A better budget would be $10,000 to $12,000, but you should still have some money in reserve for extra costs.
