Cleaning slate or tile roofs

Whether its roofing tiles or slates, expect Green Clean to effectively remove your moss and algae problems within 48 hours. Simply Spray & Leave, and let Green Clean do the rest.

Green Clean should be applied to dry areas, exposed to sunlight. If used on damp or shaded areas, speed of algae removal will take longer and may require a second treatment. Green Clean is not a weed killer and will not be effective against weeds.
