This roof in Davidsonville, MD had a bad infection of gloeocapsa magma and lichen spotting on the front half of the roof. The back half was pretty clear of any visible black streaking, but we treated the entire roof since this organism spreads aerially. With the strong rain storm we are having this spring in Maryland, this roof and all the others we did last week will be rinsed clean – looking fresh, clean and new!
We do not need to rinse the roof, saving our customers' money and being environmentally responsible all at the same time.
