A pressure washer will strip the protective granules right off asphalt shingles, force water under them, and can void your roof warranty.

This is the method roofing manufacturers and the ARMA industry association call for.
The black streaks are Gloeocapsa magma, an algae that eats the limestone filler in shingles and spreads fast in humid South Central Oklahoma. Left alone, it holds moisture against the roof, along with the moss that grows in the shade, and both shorten roof life. A soft wash clears it, restores your roof's appearance, and buys you years before it returns. Pair it with house washing and gutter brightening to clean the whole exterior at once.
