How to Treat Roof Moss Chemically

While a home carefully integrated with plants and trees is highly appealing, one overrun with moss is the exact opposite. Unfortunately, because of high moisture and shade, the roofs of many homes can quickly become littered with moss. For homeowners struggling to keep their roofs clear, a simple bleach solution will clear the roof of moss and restore the home's grandeur.
