Thank you for sharing your experience, as i can see this post is about 5 years old, so what do you say about this method, are you still benefiting from it? is it best solution?

In summers roof of my house always gets very hot and impossible to sit in the upper lounge without 1.5 ton unit running at 24°C or below. I wanted to find a solution to cool down the roof. Lately I saw an ad of ICI weather shield stating it can bring down the temperature by 5°C. So I thought to do an experiment on the roof. To my amazement the end result was amazing and actually today I am sitting comfortably at the upper storey without AC while temperatures are :
inside : 33.7°C
Temperature outside: is 41.7°C (in shadow) & 43.5°C (in sunlight). (14th May 2011)
Difference: 7°C to 10°C
However, before the application, I did a recording of temperature, (probably 10 days)
Inside Lounge: 33°C
How I did this ?
The roof of my house is brick layered. I inspected and found it had lots of grime & dust. The only way to remove it was using metal wire brush. Here are the pictures of the roof before cleaning:

thank you so much for your detailed post.
i am from Karachi, and we live in two story house, we are currently in upper section ie at first story and there is roof above it (no any thing built on roof). and it remains very hot in summer and i am planning to go for insulation.
will this be best option? because it requires to clean the roof surface more often to get optimal results which seems very tedious task and if one cleans the surface more often than there are chance to wipe out the color.
so you still feel this is best option?
are you still getting optimal results after 4 years?
