A properly designed and installed extensive green-roof system can cost $108–$248/m 2 ($10–$23/sq ft) while an intensive green roof costs $355–$2,368/m 2 ($33–$220/sq ft) However, since most of the materials used to build the green roof can be salvaged, it is estimated that the cost of replacing a green roof is generally one third of the ...

A thatched roof ensures that a building is cool in summer and warm in winter. Thatch also has very good resistance to wind damage when applied correctly. Thatching materials range from plains grasses to waterproof leaves found in equatorial regions. It is the most common roofing material in the world, because the materials are readily available.
The solar reflectance of green roofs varies depending on the plant types (generally 0.3–0.5). [32] Green roofs may not reflect as much as a cool roof but do have other benefits such as evapotranspiration which cools the plants and the immediate area around the plants, aiding in lowering rooftop temperatures but increasing humidity, naturally.
The roof of an earth shelter may not be covered by earth (earth berm only), or the roof may support a green roof with only a minimal thickness of earth. Alternatively a larger mass of earth might cover the roof. Such roofs must deal with significantly greater dead load and live load (e.g. increased weight of water in the earth after rain, or snow).
A sod roof, or turf roof, is a traditional Scandinavian type of green roof covered with sod on top of several layers of birch bark on gently sloping wooden roof boards. Until the late 19th century, it was the most common roof on rural log houses in Norway and large parts of the rest of Scandinavia.
