What are green roofs?
Green roofs are engineered roofing systems incorporating the use of vegetation that make environmental, economic, and social contributions to urban areas. The Green Roof Research Facility focuses on extensive green roofs. Green roofs have limited impact in short span construction. The weight of a 3″ green roof is approximately equal to gravel ballast use in inverted roof systems. For long span construction, load considerations may require structural engineering.
Green roofs are vegetated layers that sit on top of the conventional roof surfaces of a building. Usually a distinction is made between ‘extensive’ and ‘intensive’. These terms refer to the degree of maintenance the roofs require. Intensive green roofs are composed of relatively deep substrates and can therefore support a wide range of plant types: trees and shrubs as well as perennials, grasses and annuals. As a result they are generally heavy and require specific support from the building. Intensive green roofs (what most people think of as roof gardens) have in the past been rather traditional in their design, simply reproducing what tends to be found on the ground, with lawns, flower beds and water features. However, more contemporary intensive green roofs can be visually and environmentally exciting, integrating water management systems that process waste water from the building as well as storing surplus rainwater in constructed wetlands. Because of their larger plant material an
A green roof is a living roof. There are two broad types of green roofs: Extensive green roof: A roof covered with low growing vegetation providing economic, environmental and aesthetic benefits. Extensive green roofs are a light weight, low maintenance and an eco-sensitive alternative to conventional roofing. The depth of the growing medium is between three and six inches. Intensive green roof: A roof substantially covered by a garden growing in over six inches of growing medium. An intensive green roof is like transposing a garden from the ground up onto the roof. It is high maintenance and the plants are generally larger. An intensive green roof is generally accessible to visitors. Image Benefits of a green roof: • Roof lasts longer than a conventional roof because it is protected from UV light.
To put it simply, green roofs are exactly what they sound like. It is a roofing structure that uses vegetation to cover over the roof of a home or commercial building. Moss Acres offers an extensive style, low profile moss based green roof. This means that there are fewer, lighter weight layers which are typically less expensive and more easily maintained. We suggest using a few different types of moss, including fern moss or rock cap moss. Neither of these types of moss require a lot of attention to flourish. They need very little sunlight, can endure very hot or very cold temperatures and require very little water once established to survive. If there happens to be a drought or it gets very cold, the moss will go into a dormant state and preserve itself for week or months at a time.
