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?
Roofing shingles come in many different styles, shapes, colors and patterns. But every roof has but three basic shingle (or tile) types. This article explains the three basic types of shingles and tiles which are produced. We're not talking about specific products here, simply the types of each product.
Starters Shingles and Starter Tiles
Starter shingles are, as their name implies, the starting shingles of a Roof System. They are installed on top of the Drip Edge/Rake Edge and on top of the Leak Barriers and begin the overlapping pattern for the remainder of Shingles (or tiles) on the roof. Simply put: One single row of starter shingles is installed everywhere your roof ends, ie: in the same areas as with Metal Drip Edge and Rake Edge.
As with every other part of a Roof System, different types of starter shingles are offered by many different manufacturers. Fortunately for you, you don't need to select what type of starter shingle to use on your roof, because the manufacturer of the Field Shingle you chose chooses for you. As long as your Roofing Contractor follows the manufacturers recommendations when selecting starter shingles, you're in good hands.
A note of interest: starter shingles set the beginning pace for the rest of the Shingles on your roof. If the starter shingles are installed straight, then the installation technician will be off to a good start. Also, starter shingles usually need to be installed off set from the remaining Shingles on your Roof System to allow for a proper overlap of the remaining shingles or tiles.
The final touch. Ridge Shingles are to your roof like a picture frame is to a picture. What kind of frame did they put around the Mona Lisa in the Louvre? I'll bet you it wasn't purchased at Wal-Mart... And what a difference it makes to have a good quality ridge shingle installed. The bottom line is, visually appealing Roof Systems include visually appealing ridge shingles.
If you are not concerned with the visual appeal of your Roof System, then save a buck and use a standard cut shingle for your ridge caps. If however you'd like your house to look more like your castle...use a definitive edge ridge shingle such as an IKO Ultra Hip or a GAF/Elk z-ridge. The price difference between a regular ridge shingle and a more visually appealing ridge shingle on a standard home is around $400 - $800.
Important note: Higher quality ridge shingles typically require special installation procedures when installed. It may be wise to mention this to whoever you choose to install your roof. Ridge shingles are located at areas of your roof most vulnerable to wind damage and therefore subject blowing off if they are not installed properly. Ask your roofing contractor what sort of Special Installations are required for installing high quality ridge shingles.
Environmentally Friendly Roofing
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.
