I know that one of the most important aspects of keeping a house cool is to vent the roof properly with appropriately sized vents in the eaves / soffits and on the ridge, all of which I have added to this house since I moved into it a couple of years ago. I also installed a power vent on the gable; however, it triggers very frequently on sunny, fairly cool days (60-65 degrees F)--- even though it is set at
105 degrees F --- and therefore I think I am still facing a problem with my attic.It's my first house with a black (heat sink!) roof, and was wondering whether it would be worth a try to arrange a soaker hose (or another similar contraption) on the ridge that could be used to occasionally thoroughly wet the shingles to cool them down.
I obviously would have to make a system that I can drain completely in the winter, that would be seriously grounded, and that I could turn on and off at will, maybe with some sort of a timer. Honestly, I don't think that there are major construction issues there.
From a cost stand-point, in our area at least (Ohio), water would be much cheaper than the electrical power used to cool the house or power the vent, so I think that it would be an advantage: I could actually use the run-off for watering purposes, but that'd be somewhat more involved than I want to tacke right now. I cannot figure out that it would do any damage to the shingles, but I am less certain; it should be no worse than a sudden thunderstorm in the summer.
However, I am wondering whether anyone had already done such a thing, and whether any of you foresee problems that I am overlooking.
Thanks in advance.
