Roof Clean Xtreme is a fast acting, high performance cleaning product that will enable a roof to be cleaned without intense pressure washing. Roof Clean Xtreme will quickly remove all forms of organic growth from any type of roof tile including clays, without risk of damaging the roof. For best results dilute the product 1:1 and apply to a wet surface by watering can or sprayer. Keep the roof tiles damp throughout the 60 minute period, then hose or lightly pressure wash away with clean water. For areas of heavy contamination or soiling, leave product on surface for longer or re-apply.

Roof Clean Xtreme is the best roof cleaning product for slate or concrete roof tiles. It combines 4 powerful, active cleaning ingredients and a biocide to inhibit further growth of moss and algae. It will also work as a shingle roof cleaner and regarded by many professional roof cleaning contractors as the best roof cleaning product around today.
