The first pic is the after pic. The bottom pic is how this roof looked before we started. We never stepped a foot on this roof to clean it. We didnt use a pressure washer or kill any landscape or small animals. This roof will get even cleaner in a few rains. There are tons of roof in Colonia, Scotch Plains, Clark and surrounding areas that have algae infestation. This type of algae feeds on the crushed limestone that is used as weight for the roofing shingle. She couldn't have been happier. She was glad to pay $385.00. It didn't cost to clean this roof, it paid.
