What Is Green Roofing?

History Insulation Contractors South Bend Indiana
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.

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.
Intensive green roofs involve more “intensive” maintenance and care. Such structures that hold gardens or parks on the roofs are considered intensive. Often these roofs are accessed by people for pleasure. To simplify the definition, if the type of vegetation planted on the roof needs constant care be it weeding, watering or feeding, it is intensive. This style also requires more layers to promote proper drainage and irrigation, so more often intensive roofs are flat roofs.
Extensive roofs are closer to the original sod style roof. The area is only accessed for maintenance, and, in general, only once or twice a year. It is given fertilizer or weeded, but otherwise left to its own. Often these roofs are pitched roofs, so a thinner layer of material is needed to sustain the vegetation, as the natural slope will allow for proper drainage.
Green roofs are believed to have a number of positive impacts on the environment such as reducing storm water run off, creating a habitat for wildlife, filtering pollutants and lowering the heat urban impact. Financially, people benefit from the reduced heating and cooling costs, roof lifespan is dramatically lengthened, as well as being eligible for both federal and state tax breaks.
