Soft Wash Roof Cleaning
The black streaks running down roofs are actually a hardy algae called Gloeocapsa magma. As the blue-green algae accumulate, they develop a dark, hardened outer coating, which results in the black stains you see. The algae feed on the limestone in shingles. Damaging and shortening the life of your shingles. At Above All, we use a low pressure cleaning solution to not only clean the black streaks, but also killing it off down to the root system keeping it off longer.
