This is a recipe that I received from a home inspector that my clients hire regularly. I share it with all of my clients that have some mold or moss on their roof. I hope it helps you too!!
1 Gallon of Water
1 Cup of Bleach
1 Cup of Laundry Detergent Powder
Apply with a garden sprayer. Wait 20 minutes and rinse with a garden house spray nozzle.
