Funny thing is that a coworker tried this. He said it made his shingles look really old quickly and didn't really do a whole lot other than that. Perhaps you are good (or bad) at math. You might start by looking at the accuracy of your thermometer. Only a few I know will discern accurately the 1.6 degree drop in temp you say, and they are expensive. In other words, the temp could well have gone up with the measurement error added in. Another thing to consider is the heat capacity of the water, and where that BTU capacity is best used - perhaps not cooling your roof. Did your living space get cooler? Probably not. Would a $50 attic fan do a 50x better job? They do seem popular. I suspect there is a reason the world isn't equipped with roof sprinklers. - Nate
