Get us to do it for you! I have seen a few roofs recently being cleaned by jet wash in my local area. It is a matter of months before the moss is growing back. Why? Because people are not providing a proper service with longevity behind it. We remove the moss, and then apply a biocide product that continues to work with time. It delays the moss from appearing. We have great success with our product and we are registered trained applicators of it.
Does the man knocking on your door with a jet washer offer the same service?
