What causes roof stains?

 

Those unattractive, dark stains that reside on your roof are caused by “blue-green” algae, Gloeocapsa magma. It thrives and grows on asphalt shingled roofs in much of the United States. Growth of this algae usually starts on shaded areas of the roof, and usually on the North side. As the algae grows, it holds moisture which causes the growth process to accelerate. This is the reason the roof stains get worse over time.

Algae spores are carried by wind, birds, squirrels, etc. It is unavoidable. If your roof is clean now, look at your neighbors roof. If they have a stained roof, then it won't be long and your roof will be stained as well.

 

These stains have caused many home owners across the country to spend thousands of dollars having their roof replaced when they could have restored it to a like new finish for a much lower cost.

 

Ugly roof stains are not the worse problem, unfortunately it also damages the roof. Algae, mold & mildew grabs on to the shingles removing the granules which protect the roof. It holds water to the surface of the roof and can cause rot & decay under the roof. These unsightly contaminants discolor the roof and will shorten the life of the roof leading to earlier than necessary roof replacement.
