A green roof in Dunedin 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 Dunedin 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?
Going green has rapidly become popular for a number of reasons ranging from ecological responsibility to revenue generation and savings. As people install upgraded weathering, siding, windows, and air conditioning systems in their homes, they tend to miss the opportunities that are open with roofing. Using a material that is recycled is a great step in being environmentally friendly. Solar systems like solar shingles will even power your home, reducing your energy costs, greatly. However, roofing systems can also collect rainwater for future reuse.
Rainwater collection is the accumulation of rainwater for future use. Usually this occurs before the rainwater reaches your local aquifer. The system is comprised of a few basic components;
- Catchment Area
The catchment area is the area on which the rainwater is collected, usually the roof. Conveyance refers to the transportation of the rainwater from the catchment area to the storage and is considered the gutters and downspots of a roof. Storage refers to the storage tank where rainwater is collected. In order for rainwater to be consumed it must be treated.
You can determine your roof's square footage by adding the square area of your home or building and adding the area of "roof overhang" or square area of roof that extends beyond the boundaries of your home or building.
You can also estimate your harvested water by using a calculation from Texas A&M University's AgriLife Extension website;
Harvested Water (gal) = catchment area (ft2) X rainfall depth (in) x.623conversion factor
Roofs - A Passive Income Generator
Many people already realize the tremendous value of their roof whenever they step outside in a hot sun. For years people have already been harvesting the opportunities that solar energy roof systems offer. However, with a rainwater collection system, a roof can start generating revenue even when there is no sun out.
Green Roof Systems
Before I became involved in the world of green building I had never even seen an eco-roof. The first time I saw one it struck me that from a purely aesthetic or architectural point of view they create a sense of integration, or synthesis between the structure and the surrounding landscape, but that isn't even the half of it...
I had the pleasure of interviewing Rosalind Haselbeck who along with Richard Alianelli form Building Green Futures, a San Diego company that specializes in living roof installation, here's what she had to say;
BIGC- So what do you see as the chief benefits of a living roof?
BGF- The answer to that depends on your idea of 'beneficial' I would say the greater benefit lies in the many environmental aspects, such as the regained space for plant life (pollution and CO2 reduction) as well as mitigation of the urban heat island phenomenon. However for the individual property owner his immediate and personal benefit lies in the exceptional insulation, and temperature reduction/stabilization effects, as well as improved storm water management due to the absorptive qualities of the growth medium and plant life. Did I mention they are beautiful?
BIGC- And maintenance?
BGF- That varies depending on type. Generally you would maintain your green roof twice a year, weeding, clearing drains, fertilizing- the same sorts of things you would do with your regular garden or landscaping...only on your roof.
So there you have it from the horses mouth. There are many factors involved in the world of green roofs. It all comes down to what is right for you and your budget. The good news is that there are now professionals out there like Rosalind and Richard who have made it their business to green the roofs of the world.
