As a corrosive chemical, bleach can damage the metal flashing that seals the components of the roof that are most vulnerable to water damage. This sort of damage can lead to issues that will ultimately require more extensive repair. Others will advise homeowners to use a pressure washer on the roof to remove stains, but this will result in granule loss even when the pressure washer is used on its lowest setting. Even a garden hose may be pressurized enough to cause granule loss, so a pressure washer should certainly be out of the question.
A specific roof cleaning product is best, so the homeowner should select a noncorrosive roof cleaner that will remove algae, moss and lichen without disturbing the granules or adversely affecting any of the other roofing materials. The homeowner should select a day when it is overcast and there is no precipitation in the forecast, as this will allow the cleaning product to be most effective in eliminating staining and preventing future issues. Of course, professional roofers are also capable of performing this task for homeowners concerned with the inherent safety issues or with the possibility of causing roof damage unintentionally.
