I was reading an article where a guy used water to cool the top of his house, it ran down the roof, then he had a pump recycle it and cool the house again with the same water. Occasionally he had to add more water but he said it worked fine. You think this would be an economical way to cool a concrete house with a concrete roof?

It works well but the cost of mains water may be high. Take a ride around some remote fire stations during hot days and try and figure out why the roofs are wet.

To pump water all the way up to the roof you probably need at least a 1/2 hp pump. Electricity cost would be significant and the trade off in a few degrees difference I think would be negligable. A typical water pump would probably have a lifespan of 2 years if operated 24/7. Secondly, concrete roof will leak whether you like it or not so the repair bill is going to cost you. Third, dead spot which holds water is good breeding ground for mosquitos. Yeah it is workable but probably not practical.

I went up there thinking I could change a spotlight by reaching over the edge of the gutter, but the pitch is really steep once you get up there. The short answer is nothing :( In high school I used to climb all over the roof of my parent's house like frigging Spiderman. I took a girlfriend up there and got drunk for the first time. We listened to the radio,smoked cigarettes and drank creme de menthe, straight from the bottle. Yeah, the stuff you put on ice cream. Gah....I still get sick thinking about it. At least we had some rooftop sex before the puking began. If they had Google Earth back then, maybe we would have made Youtube, who knows?

Sure. Gravel and water. The gravel disperses the suns rays and the water evaporating cools it off. Saves AC.

It works and it has been used. But it is not a good way of cooling a house.
PS: Did you know that chemo for lung cancer costs $30,000 on average and prolongs your life for up to 2 months? I think that is money well spent.

I don't know about a concrete roof but it has been used for tin roofs and it works.

yea my friend did it, and a lot of it vaporized when it was comming down, if you can recycle it, it might be a huge help, but if not the amount of water wasted + the money you spent doesn't come out very good

Yes it works, But you are only cooling one surface of the house (the hotest one) and you only tend to get a few degrees.

We saw a cinder block building that nominally had water layer on the roof.
But you can't do this where it freezes all the time. We saw this in Los Angeles.
