Those ugly black streaks and stains on your roof aren’t dirt. They’re the handiwork of an airborne cyanobacterium called gloeocapsa magma. Its favorite foods are moisture and the limestone particles embedded in your shingles to reflect ultraviolet light and stand up to the elements.
Left alone, it will multiply, prematurely rot your shingles (and maybe even the joists supporting them), and take shorten your roof’s life by years.
At Affordapro, we first apply antibacterial detergents at low pressure. Next, we use low-pressure water to gently rinse away the mold, lichen, mildew – and, most important, the bacteria – without harming the shingles. (Unlike some companies that rely on the next rainfall to wash it off.)
This process adds a little time to our work. But that’s worth it, because it adds years to the life of your roof.
