Re: Cooling attic (and home) by spraying water on roof (shingles) - good/bad?

Besides the glaring fact of WASTING WATER?  Do the math on your water bill
(or the electric to pump your own well water) and you'll probably find it's
a helluva lot cheaper to just leave the roof alone.  If anything, put in an
attic vent fan.  Water's not as harmless a material as one might imagine.
The various minerals causing deposits, the likelihood of algae other
mold/fungus growth and even it's weight are all factors to consider.  Enough
that unless the roof was designed with in mind would make it not only a bad
idea but a potentially dangerous one at that.
