Commercial Roofing: The Benefits of Green Roof Systems
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.
