What are those ugly roof stains?

Black algae usually grows on the North side of the home as well
as areas under trees. The North side of the home gets the least
amount of sun and therefore stays wet the longest. The same is

the chemicals in the ground guarding your home. In short,
using chlorine is not worth the risk when there are other much
safer and less costly alternatives.

YES! Never use a standard commercial pressure washer to clean
your roof. Using a pressure washer will clean the stains from
your roof but will also remove the surface of your shingles.
Many homeowners have replaced their roofs within just a few
years after cleaning it with commercial pressure washers
