Green Roofs Are Environment Savers

The increasing popularity of green roofs can no longer be explained by their benefit for reducing air pollution in densely populated cities alone. Green roofs contribute to the environment and the quality of life in many different ways and yet there are many more advantages that are only evident at second sight.

FREMONT, CA: Since the 1960s, green roofs have had a resurgence in Germany, and their use has grown significantly throughout Europe and the US. The benefit of green roofs for lowering air pollution in densely populated cities alone is no longer sufficient to explain their rising popularity. There are numerous ways that green roofs benefit the environment and human well-being, but there are many more advantages that are hidden at first glance. A rooftop with a plant roof is intended to make up for the vegetation footprint that was destroyed during building development. Intensive and vast green roofs are two different types of green roofs. The underlying structure (depth of growing medium) and the kinds of plants employed vary amongst them. Both have extremely similar structures, with additional layers on top of the supporting framework. Numerous plant species, including trees, shrubs, and perennials that demand intensive upkeep, can be found on intense green roofs. They are frequently open to the public, park-like constructions for recreational use. Due to the need for deep substrate layers, extensive green roofs are often only put on flat rooftops. Extensive roofs, in comparison, have smaller plants and require less upkeep. Since their roots are shallow, they can thrive on thin substrate layers. Herbs, grasses, mosses, and drought-tolerant succulents are among the plants employed. Apart from the fact that they are typically inaccessible to the general public, extensive rooftops offer the same advantages.

Many types of roofs, although not all, can support a green roof. The most common construction material is concrete, which offers the most stability, but wood, metal, plastic, gypsum, and composites can also be utilised. Naturally, flat roofs are ideal for conversion to green roofs, whereas other surfaces pose more of a problem in terms of design and weight distribution.
