Costs for green roofs in the United States are estimated to average between $15 to $20 per square foot for all use types, i.e., high density residential, commercial, industrial etc.1 These costs include all aspects of green roof development, from the waterproofing membrane to soil substrate creation to planting.
Some roofs are flat and others are steep. Some roofs are made of wood and others, metal. Only touching on the myriad of roof cost factors, itâs no wonder the average cost of a new roof ranges from $5,300 to $12,000. Nonetheless, after analyzing over 19,000 roof installations across the country, we found that the average roof estimate comes in at $6,364.
