A green roof in Wellington is known by several names such as ecoroof or living roof. They have been built on buildings for centuries. Many countries in the world have green roof subsidies or programs that encourage ecoroofs. Scandinavia has long had farm house buildings that have sod covered roofs. Some cities in the US are known for their living roofs such as Chicago’s City Hall building.
Basically a green roof is a roof that has vegetation and a growing medium. It will cost more than a standard asphalt shingle roofing application. Rooftop garden costs also depend on the type of green roof installed. There are several differences among green roofs in Wellington and some applications that may or may not be defined as a green roof such as a container garden green roof.
What Is Green Roofing?
Sod roofs have been part of Scandinavian structures for generations. These are homes where sod (or grass cover) is planted on top of layers of birch wood. The style is mostly associated with log cabin type dwellings. However, it wasn't until Germany in the 1960's that the modern take on "green" roofs used for environmental purposes came into vogue. Now, most of Europe has government incentives and encourages builders to use the technique. It has only been in recent decades that the popularity and government incentives have brought green roofing to the United States.
What is Green Roofing?
Modern green roofs involve planting local vegetation on top of waterproofing membranes that are affixed to the roof of a building. There are layers of material designed to house roots and create irrigation and drainage. Some structures are completely covered with vegetation, while others may only be partially covered. Green roofs fall into two main categories, intensive and extensive.
Costs for installing the green roofing is considerably high. The waterproofing layers along with beefing up the support structure adds up quickly. Plus, unlike a typical roof, there is considerable more maintenance. Some people worry the vegetation will suffer from lack of rainfall. However, the way the drainage is designed, the roof will survive lengths of drought. And since local vegetation is used, it will also survive winter months.
