Melbourne Green Roof Tray System

A green roof in Melbourne 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 Melbourne 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?

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.

Green Roof Pros and Cons

Roofs are different wherever you go. Just about every building around the world has one, but they vary in shape, materials, durability and construction. Why is this so and why hasn't someone come up with the definitive roof for all roofers to copy?

Depending where in the world you live roofs have a variety of purposes. Primarily they are to protect against rainfall, but also they give shelter from sun, wind, cold and heat. Characteristics also differ according to local architectural style, available materials, wealth and the purpose of the building.

The main influences on the shape and look of a roof are the materials available, on how the roof is supported and on whether the roof is pitched or flat. Roof support is usually provided by timber, bamboo, cast iron, steel or metal rods encased in reinforced concrete. Bamboo is very flexible and so in Asia, where it is commonly used, roofs are often curved. Timber is versatile and can provide virtually any shaped roof - from low and high pitch to dome shapes. Metal supports are good for large, heavy roofs.

But the basics will remain - areas of high rainfall and snow such as Scandinavia will continue to have high pitched roofs. Dry areas such as the Middle East will stick with the simplicity of flat roofs as they have little rain to deal with. In addition many Governments are increasingly protective of local style and resistant to design which ignores regional tradition and taste.

Roofers around the world have different methods and materials to work with and this will always encourage a range of roofs to enrich our skylines.
