Our pressure washing pros recently soft washed every building in the foxcroft condo association and they turned out great. the buildings had spots with green organic growth buildup as well as areas near lights with heavy insect debris. We also cleaned a small section of roof for them to show them what the rest of their roofs could look like with a good cleaning. The before and after shows the black streaks gone, and the moss dead and ready for the rain to wash it away.
