  1. On the nearest cloudy day, start to remove the moss using a detergent or chemical solution of your choice. You should wait until the day is cloudy to make sure that the solution won’t evaporate speedily. Scrub the solution into the affected area gently but thoroughly.
  1. To prevent the moss from developing again, install sheet metal with copper coats or zinc strips. Set the metal underneath the upper ridge on the roof’s sides. Zinc is less expensive, but copper is more effective in preventing algae and moss.
