A green roof in Carrollton 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 Carrollton 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 Systems
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!
