Reader cautions against washing membranes
I enjoyed NRCA's Director of Technical Services' Jason Wilen's article "It's a wash," July issue, pages 26-31. However, there was one crucial shortfall. In California, the Environmental Protection Agency will heavily fine a contractor if he or she is caught washing a roof without capturing and filtering the water. It cannot be washed to the ground nor dropped into the storm drain system.
Be careful; the fines are thousands of dollars!
