A green roof in Sarasota 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 Sarasota 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?
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.

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.
