Instead, you should clean your roof with just regular soap and water and a scrub brush. I've gotten stellar results using an oxygen bleach solution. Some people use chlorine bleach and water, but chlorine bleach is highly toxic to any vegetation that surrounds your home. Any chlorine solution that drips or that is rinsed off the roof can kill your landscaping. Oxygen bleach does not harm vegetation. It's best to clean a roof when it's cool and the sky is overcast. Working on a sunny day will cause the cleaning solution to evaporate in seconds or a few minutes. Spray the oxygen bleach solution on the roof working in strips from top to bottom of the roof. Each strip you clean should only be 4 feet wide.
