A roof garden is more personal garden than the one on the ground level where you can sip coffee, read and rejuvenate yourself surrounded by waterbodies, lush green natural grass, plants, bar, barbecue and much more..
In rooftop garden, space becomes available for localized small-scale urban agriculture. Available gardening areas in cities are often lacking, which is likely the key requirement for many roof gardens. The garden may be on the roof of an autonomous building which takes care of its own water and waste. Unlike any type of garden, roof garden also needs a detailed plan. Roof gardens look good if they are proportionate with lawns, shrubs, ground covers, sitting area, bar, barbecue and small trees.

2. Reduces air conditioning cost by25% to 50%.
Environmental benefits:
1. Insulates the building against heat and cold.
2. Reduces indoor temperature by 6- 8 degree.
3. Reduces sound pollution.
4. Increases the amount of oxygen in air.
5. Filters air borne particles from air.
6. Controlling storm water runoff, erosion and pollution

25. How does a terrace garden affect the conventional roof below?
Terrace garden doubles the life of the conventional roof.

26. Is irrigation required? If so, what kind?
With thoughtful engineering, irrigation is rarely necessary. When irrigation is required, the water should be delivered deep under the surface where the roots will seek it and it will not be lost to evaporation.

27. Why is drainage important?
Proper drainage ensures that the growing medium will be maintained in an aerated condition suited to health plant growth. Drainage must also be designed with large rainfall events in mind. The goal is for all rainfall to percolate to the base of the system. The portion that is not absorbed should move 'underground' toward roof drains or scuppers. Drain should also be provides at lawn level s that during heavy rainfall water gets drained out.

Energy savings will be greatest in low buildings, due to the high ratio of roof area to the total of exposed building skin. The benefits will also be greater in warm climates, where cooling is the principal energy cost. It reduces 25% - 50% of air conditioning bills..
