Lots of streaking going on, and we don’t mean the clothe-less type. These photos were taken in Highland Park, an Avon, Ohio community. Clearly, the “algae inhibitors” didn’t do much good. Since approximately 1/2 the view of all homes is the roof, think of how much nicer these once beautiful homes would look with no streaking. Metal roofs never streak, of course. Not now, not 50 years from now.
