Safe Roof Soft Washing in Oceanside
This Oceanside homeowner was alarmed by the dark black streaks spreading across their asphalt shingle roof. Those streaks are caused by Gloeocapsa Magma — a cyanobacteria that feeds on the limestone filler in asphalt shingles, slowly destroying the roof from the outside in.
Their first instinct was to hire a pressure washer. That would have been a catastrophic mistake.
Why You Must NEVER Pressure Wash a Roof
High-pressure washing blasts the protective granules right off asphalt shingles. Those granules are the shingle's UV shield and waterproofing layer. Without them, your roof deteriorates rapidly and your manufacturer's warranty is voided instantly. The Asphalt Roofing Manufacturers Association (ARMA) explicitly states that only low-pressure soft washing should be used on asphalt roofs.
Our Roof Soft Wash Process
We applied our specialized roof-safe soft wash formula that kills the Gloeocapsa Magma bacteria at its root without disturbing a single granule. The solution dwells on the surface, breaking down the black streaks and organic growth. A gentle rinse follows — and the roof is restored to its original color.
This Oceanside homeowner saved an estimated $12,000-$18,000 in premature roof replacement costs. Our soft wash treatment extends roof life by years and the results are dramatic.
