While dirt is undoubtedly on your roof, it's not the culprit that's blighting your rooftop. Dark black streaks that are so often seen on roofs are the cause of pesky algae known as Gloeocapsa magma. Gloeocapsa magma appears wherever there is a hard surface to cling to, moisture, and a touch of shade. It's most often seen on roof shingles, but it can appear on most external surfaces.
With a professional roof cleaning service from Cornerstone HydroWash, our experts will remove all algae, mildew, and muck that is spoiling your shingles. Your roof will look better, last longer, and enjoy increased energy efficiency with a routine maintenance service from our pressure washing services.
