Diana<\/span> from Pennsylvania<\/span><\/span><\/span><\/p>\n<\/div>\n Diana, it is pretty common for the terms mold, mildew and algae to be used interchangeably. For now we’ll just refer to them as “black stains”.<\/p>\n You mentioned that 2 years ago a roof shampoo company removed black roof stains, and now those roof stains are returning. It’s not surprising because the mold, algae and mildew that form the stains typically will grow back 15-24 months after being removed. The spores that cause these stains are airborne, and probably landed back on the roof a few weeks after cleaning, and have been growing ever since.. We recommend for Roof Stain Prevention using Roof Armor<\/a> every year to wipe out any mold colonies that have been growing. Roof Armor is only applied to a visibly clean roof.<\/p>\n Second the black stains on your retaining wall and concrete are most likely caused by the same mold or algae. Either way the same product can be used to clean them both. Cleaner Today OX products can be used on Siding, Wood, Concrete, Patios and Retaining Walls. Choose from Roof OX<\/a>, Siding OX<\/a> or Wood Ox<\/a>.<\/p>\n<\/div>\n<\/div>\n \/\/ <\/p>\n","protected":false},"excerpt":{"rendered":" 2 years after an expensive roof shampoo to remove black algae stains from an asphalt roof, the stains are back and now black mold or algae is also covering a retaining wall and patio.
