Frequently Asked Questions
What causes the black streaks on my roof?
Those streaks are a blue-green algae called Gloeocapsa magma that feeds on the limestone filler in asphalt shingles. It thrives in the humid Southeast and spreads by airborne spores, which is why it often appears on several houses in the same neighborhood at once.
Will roof cleaning damage my shingles?
Not the way we do it. We use a no-pressure soft wash treatment, which is the method recommended by shingle manufacturers and roofing associations. Pressure washing a roof strips protective granules and can void your warranty, so we never do it.
Does roof algae actually hurt anything?
Yes. The algae holds moisture against your shingles and slowly eats the filler material, which shortens roof life. It also darkens the roof surface, which raises attic temperatures in summer. Cleaning it is cheaper than replacing a roof early.
