Not only are those black streaks and mold on your roof annoying, they are actually harmful! In fact, insurance companies have threatened home-owners in the past with the cancellation of their insurance if they do not clean their roof. The reason is simple: mold is a living organism, and like all living organisms, it has to eat!
That’s right, your roof is being slowly ingested by these micro-organisms! In order to save you thousands of dollars on roof repair/replacement costs, we recommend a thorough cleaning of your roof every few years (or when you start to notice these black streaks). This practice will prolong the useful life of your roof. We use safe low-pressure cleaning techniques with chemicals to kill the mold spores at the root which prolongs the time in between cleanings to give you the most value for your money.
Never Pressure Wash your roof!
