A green roof in Rome 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 Rome 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?
The green movement spawned a new kind of roofing system that combines soil, plants, and other natural elements to form a rooftop ecosystem. Popular in many areas, green commercial roofing systems (a.k.a. natural systems) are quickly becoming the preferred alternative to conventional systems that do not weather well, and saddle building owners with high roofing repair bills. If you intend to implement a green roof, below are seven reasons to move forward with your plans:
Improved Storm Water Management
Green systems improve storm water management by storing water in the substrate, where it is absorbed by plants, and then returned to the atmosphere by transpiration and evaporation. By retaining storm water, a natural roof can help extend the lifespan of drainage systems by reducing the volume of water they receive. Research shows that a natural system can retain up to ninety percent of the rain that falls on them.
Depending on their construction, green roofs can reduce outside noise by up to 50 decibels. The interiors of urban buildings are prone to an influx of low frequency noise caused by transport systems, automobiles, and industrial work. Green systems excel at providing a barrier to this noise.
If you need a commercial roofing system, implementing a natural system may be the best option. In addition to improving the aesthetics of your building, a green roof can improve storm water management, reduce ambient heating, improve energy efficiency, reduce the cost of roofing repair, improve building value, attract employees, and reduce noise.
Eco-Friendly Roofing Materials
There are many advancements in building materials that assist in saving money and energy. Though research on this topic was initially launched for energy preservation purposes, it also helps in saving money as well as preserving environment.
U.S. Environmental Protection Agency (EPA) has determined that nearly $40 billion is spent to air condition buildings in US, which amounts to one-sixth of the total electricity generated annually. In order to cut down these costs, EPA has come up with different roof materials and plans.
Roofing products should meet two specific conditions namely (1) They must be reflective, referring to the amount of light energy being reflected away instead of absorbing and (2) They must have high emissivity, referring to the quickness of how the absorbed energy is emitted into the atmosphere again.
Another type of roof that helps in saving money and energy is a green roof, which comprises a vegetative layer grown on the rooftop. Such a roof is able to offer shade and avoid heat through evapotranspiration, leading to reduction of temperatures of roof surface as well as surrounding air. These roofs act as insulators, thus reducing the demand for energy necessary to cool and heat the building. Therefore, based on the nature of roof materials, money can be saved.
