Is a green roof expensive.

An extensive green roof is the most common and least expensive type of green roof with costs ranging from 10 20 a square foot 2. Here are the main factors that affect the cost of a green roof. From that study they concluded that the green roof would cost 464 000 whereas a conventional roof would only cost 335 000. However they point out that green roofs can be considerably less expensive up to 50 cheaper when they cover more than 10 000 square feet because of economies of scale.

However those researchers did determine that the green roof would save an additional 200 000 over its lifetime. The epa estimates that the cost of installing a green roof starts at around 10 per square foot for simpler extensive roofing and 25 per square foot for intensive roofs.
