In St. Louis roof cleaning is more and more in need for many homes because of the high humidity levels we have here in St. Louis. Roof mold is a common problem leaving a homeowner few choices on how to solve the problem.
Mostly on the northern sides of a typical home, algae begins to feed on the limestone in the shingle. Once this begins, the black stains you see just start getting bigger and bigger, until the whole side of the roof is covered in with roof stains.
Unfortunately, many homeowners with roof stains in Missouri believe they need their roof replaced because of this eyesore. That is simply untrue. Yes, if left to grow and to continue to infest on your roof, the mold and algae can take years off of the shingle life. However, if treated by a professional roof cleaner, not only will your roof look new again, the mold and algae can be killed and there is no need for costly roof replacement.
In conclusion, if you see those nasty streaks on your roof, rest assured they can be safely removed from your roof without the use of a pressure washer. All shingle roofs should be cleaned with low pressure to avoid any damage to the granules in the shingle.
