Having a roof over your head is a great blessing. Having a filthy roof over your head can be very dangerous. When roof cleaning is neglected over a period of time a deadly blue green algae starts to form on the surface. Although this formation seems insignificant during its early days but give it time and it will start to creep all over the surface of your roof.

Soon enough a carpet of blue green algae will develop and will start to eat its way into the roof. This starts to take its toll on the structure of your roof. If you keep neglecting roof cleaning then eventually you might end up spending thousands of dollars on repair.
