I am looking for ideas of what can be done with overspray on a house roof besides reroofing. The roof is newish.... 3 years.....and black Arch.asphalt shingles. The overspray is a very light in color. It has been 3 years now and after being told that it would fade after a year or so, I still see it a lot! I am afraid to spray again with black as I don't want to make it more noticeable. Any new products that may work?
