Water is a corrosive. Would mildly wear the roofing but with your limited use not much... Mineral deposits with your limited usage would be minor but still a negative factor. The net benefit of water cooling the roof would be close to the benefits of attic air ventilation..attic air ventilation would not have that set of minor problems though. Your suggestion is workable just not the optimum as I see it. It would be optimum however say in the deep south west with air temperatures over 110 in the shade... but then mineral content of the water is higher there and could be a very significant problem one would have to look at... it is typically not done. I might be inclined to put a spray misting system in the attic air make up stream. that would work. However misting companies will not sell into a high mineral content water area because the minerals destroy their PD pumps and clogg the micro nozzels....thus...we see swamp coolers used in the south west.
