The black roof streaks on the numerous roofs in the Midwest are caused by an airborne type of algae frequently known as roof algae. This algae is becoming an escalating problem in this region of the country.

Shingle manufacturers are combating the dilemma by producing algae resistant shingles. But we have witnessed cases where these algae resistant shingles have still gotten covered in roof algae so obviously the shingles are not yet as successful as the shingle producers would like them to be.

Something else the shingle manufacturers do to fight roof algae is to suggest chemicals and roof cleaning methods for algae infected shingles without causing harm to them. This method they recommend is a low pressure chemical application that kills the algae and at the same time doesn’t harm the shingles.

What is not recommended by them is using a pressure washer to clean the algae off of your roof, doing so removes excessive amounts of shingle granules lessening the life expectancy of your roof. Disregarding the roof algae will also result in premature failure of the roof.
