A green roof in Griffin 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 Griffin 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?
We spent a significant amount of money to repair the flat roof on our commercial building about four years ago. It is already leaking again. How do we maintain our roof and our sanity?
The major problem with flat roofs is that they are flat! This means there is often an opportunity for water and debris to collect. All flat roofs are designed with some slanting of their surface to allow water to flow towards gutters or roof drains. When this is interrupted the result is ponding, or puddles of water that remain on the surface indefinitely. Constant saturation from ponding will lead to a steady deterioration of the roof surface followed by water penetration. And the worse it gets, the worse it gets, to the point of major and expensive roof damage!
Even with the best of maintenance programs, no roof lasts indefinitely. Depending on your roof type, you will need to plan on replacing your roof every 10-20 years. Obviously, more expensive roofs are expected to last longer. Just as you replace the filters in your heating system on a regular basis, so must you invest in annual roof maintenance. The key is to nip the problem early and inexpensively. This is the best way to maintain both your roof and your sanity!
Environmentally Friendly 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.
