Experts recommend that you remove roof moss on cloudy days because roof cleaning products, which should be allowed to soak into the moss for at least 20 minutes, will not evaporate as quickly as they would on a sunny day. Lichens can be removed physically (with water and a brush), chemically, or both. Use the least toxic moss killer; Chemical solutions can affect the environment, as well as damage the hanging plants that grow under roofs. If you decide to use a bleach solution or other ready-made roof moss treatment, protect nearby plants with a plastic tarp.

Several ready-to-use cleaners can be mixed and applied according to the manufacturer’s instructions and allowed to kill the mildew without the necessary rinsing. Others, such as Bayer’s Advanced Moss and Algae, come in a ready-to-use spray that can be connected to your hose.
Be sure to follow mixing and application recommendations to ensure your safety and protect tile and plants from damage.
You can also make your roof moss killer – which is generally less toxic than its chemical counterparts. Chlorine bleach removes mold and mildew, but it can damage plants, so dilute them before spraying on roofs. For a good formula, mix 1 liter of bleach with 1 gallon of water and 1/4 cup of a heavy cleaner like trisodium phosphate (don’t use ammonia-based cleaners as they create toxic fumes when mixed with bleach).
Or, make an eco-friendly solution with 1 cup of oxygen bleach and 1 gallon of water. Home improvement expert Bob Vila says you can also mix 8 ounces of Dawn dishwashing liquid or 1½ to 3½ cups white vinegar with 2 gallons of water.
Pour the solution into a garden spray; choose a backpack-type sprayer, which is safer to use if you are climbing and standing on stairs.
