Why is using bleach the best choice for roof cleaning and exterior pressure washing?


Florida, especially the Greater Tampa Area have subtropical wet humid climates.  This climate provides the moisture and temperatures that algaes and molds prosper in.  Along with the organic materials used in the building materials that make up your home, provide food for the bacterias to grow.

Limestone is in your concrete driveway. Pressure washing driveways in Tampa are a very common service. The limestone in the concrete feeds the algae and when the rainy season comes the algae grows.  There is limestone in asphalt shingles as well as concrete tiles.


Using the force from a pressure washer will remove the bloom of the algae but will not kill it down to the root. This is a much more temporary solution to the dirty black streaks on your roof as it is not killing the organism. Plus the technician will have to walk all over the roof covering every square inch with pressure, breaking tiles and dragging heavy pressure washing hoses all over the roofing materials. If the heat and algae do not deteriorate your roof this definitely will year after year.
