3. INTRODUCTION
a rooftop farming is a garden which is established on a terrace, roof, usually in a house
where there is limited gardening space.
popular in urban areas
created at three different levels
1. on rooftop of a building
2. window boxes, balconies and above the ground level
3. at the podium level, around the base or on roof of large basements
help to relieve the ill effects of Urban heat island effect, pollution, global warming etc.

4. TYPE OF ROOF TOP FARMING
1. Intensive :
widely used on commercial buildings
all sizes and types of plants can be cultivated
roofs will have grasses, ground covers, flowers, shrubs and even trees
include paths and walkways that travel between different architectural features
2. Extensive :
often used for single family and multi-family residential buildings
best suited to spaces where people are seldom going to be walking on the roof surface
green roofs also fit outbuildings like sheds and garages very well
only small size plants(small root depth) are cultivated

5. OBJECTIVE
05
the long term objectives of this proposal is to introduce/demonstrate/make
available safe and healthy production of vegetables at household level.
the short-term objective of the proposal is producing fresh and cheap vegetables.
cost estimation for Rooftop Farming
survey for choosing the crop for Rooftop Farming
6. METHODOLOGY
06
Selection of Site :
the roof must be flat
strength of the roof should be enough to withstand the load of vegetation and the
materials
area should be accessible every time
the single flat roof of Neelkanth hostel was found as a favorable place
8. MEASUREMENT OF SITE
Measurement was done using 30m Invar tape.
Actual Length of roof – 9.3 m (approx.)
Actual Width of roof – 5.6 m (approx.)
Walk way along the rood – 0.5m
Free Board on both sides - 0.5m
Mesh Size required – 9m * 5.1m

10. SURVEY
it was done by discussing with locals
of the area.
it was about the type of crops which
can be sown in this area in the month
of February.
the results were as follows :

11. MATERIALS TO BE USED
Waterproof Membrane
Thermocol /plastic boxes
Drainage layer
Drip irrigation system
Soil
Compost
Protective measures of the crops
Frame for holding wire mesh
11
12. MATERIALS TO BE USED
WATERPOOF MEMBRANE
an impermeable membrane whose primary purpose is to keep unwanted moisture
away from the roof and it protects the roof.
alternative method include use of Thermocol /plastic box
DRAINAGE LAYER
it’s a porous, continuous layer over the entire roof surface just above the concrete
slab.
allows moisture to move laterally through the green roof system
prevents oversaturation
ensures root ventilation and provides additional space for the roots to grow
12
13. MATERIALS TO BE USED
SOIL
soil required would depend upon the type of crop which is to be planted.
sandy loam soil is a kind of soil used for such agriculture.
this soil is a mixture of sand, silt and clay.
ideally ratio is to 2 : 2 : 1 respectively which provide ideal drainage condition for
agriculture.
COMPOST
compost is made with material such as leaves, shredded twigs, and kitchen scraps
from plants.
with leaves and other material, Cow Dung will also be used.
13
14. MATERIALS TO BE USED
SUPPORTING FRAME
ISA 75x75x5 is to be used for supporting wire mesh and create a frame
PROTECTIVE MEASURE
wire mesh is to be used for the protection of crops by invasive species, roof is to
be covered using the mesh of given dimension.
DRIP IRRIGATION SYSTEM
for maximum efficiency of irrigation drip system is to be installed over the surface
of soil
14
16. COST ESTIMATION
Method 1 - Roof covered by soil with 1.5m height of wire mesh
16
S. No. Items Cost Dimension/Quantity Total Cost (Rs.)
1 Wire Mesh 250/sq. m 84.3 sq. m 21075
2 Soil .5/kg 12000 Kg 6000
3 Drip Line 100/m 8 of 10m 8000
4 Waterproofing membrane 180/sq. m 60 sq. m 10800
5 Mesh frame cost 33000/ton 110 kg ISA 50*30*4 3630
6 Drainage layer 620/sq. m 54 sq. m 33480
17. COST ESTIMATION
Total cost – Rs. 83000
Total installation cost excluding labor and sapling cost.
Wire Mesh Area = (5.1*2.0)*2 + (9*2) + (9*5.1) = 84.3 sq. m
Soil Volume = 8.5*4.6*0.3 = 11.73 m^3
Soil Mass = 1000*11.73 = 11730 Kg = 12000 Kg
Drainage layer Area = 9*6 = 54 sq. m

18. COST ESTIMATION
18
Method 2 – Roof covered with soil with Thermocol
Total cost Rs. 42705
NOTE : Total installation cost excluding labor and sapling cost.
S. No. Items Cost Dimension/ Quantity Total Cost (Rs.)
1 Wire Mesh 250/sq. m 84.3m^2 21075
2 Soil .5/kg 11000 Kg 5500
3 Drip Line 100/m 8 of 10 8000
4 Thermocol 45 100 piece 4500
5 Mesh frame cost 33000/ton 110 kg ISA 50*30*4 3630
19. CONCLUSION
19
Installation cost calculated from method 1 is higher in comparison with the second
one due to the use of Thermocol.
But method 2 has one disadvantage i.e. the use of Thermocol is not eco-friendly.
One can adopt any of the above two method for rooftop farming.
Method 1 require more soil hence more irrigation water will be required
Method 2 can be completed using lesser amount of mesh.
Most efficient irrigation technique was used i.e. drip irrigation
