When done correctly using the soft wash method, roof cleaning does not damage shingles. In fact, it can extend their lifespan by removing harmful algae, mold, and moss that deteriorate roofing materials over time. The real risk comes from using high-pressure washing, which can strip protective granules from asphalt shingles, loosen edges, and void manufacturer warranties.
At Pressure Cleaning Miami Aura, we never use high pressure on roofs. Instead, we apply a low-pressure soft wash solution that soaks into the shingle layers and kills algae at the root—especially the black streaks caused by Gloeocapsa magma, a common issue in Miami’s humid climate.
The solution sits for a dwell time, breaking down organic growth, and is then gently rinsed away without harming the shingle structure. The process is approved by roofing manufacturers and recommended by the Asphalt Roofing Manufacturers Association (ARMA).
In neighborhoods like Coral Gables, Shenandoah, and Westchester where shingle roofs are common, this method has proven to be the safest and most effective way to clean without causing structural damage.
With the right tools, solution ratios, and experienced technicians, roof cleaning not only protects your shingles—it preserves your home’s appearance and value.
