Direction in dia: Left side = WEST & Right = EAST.
Objective: Avoid direct contact of sunlight on roof surface.
Solution: Use 'woven coconut leaf' & stack them on wooden frames. Wooden frames should have slope as shown in dia.
This slope helps in ventilation of hot air between leaf stack & roof surface.
NO need for watering. But for extra cooling at night, water them at around 5pm-6pm.
Wooden Frame: Max height = 3 feet ; Minimum height = 2 feet (approximate)
Use from wooden crates, really economical, DIY recommended.
Woven Coconut leaf cost - really cheap, around Rs.5-10 for 1 woven leaf.

Alternative to Leaf:
1. Jute bag ('bora' in hindi)
2. Construction Safety Net (green colour)
Disadvantage: Takes roof space
Extra Advantage: Bio degradable, shelter to birds, squirrels... keep a small bowl of water for them.
