Oh no, that is not what we like to hear! Rust-Oleum Zinsser Jomax Roof Cleaner & Mildew Stain Remover is a concentrate that, when properly mixed with water and bleach, removes black streaks, dirt and mildew stains from roof shingles. It kills mold and mildew on tile, slate and metal non porous roofs. Be sure to mix in the proper portions with bleach and water (80% water, 15% bleach, and 5% Jomax) as detailed in labeled directions and chart for proper cleaning. Moss and heavy mildew stains may require a second application.
