Most people who search for roof pressure washing want the dark streaks gone. We get that. On asphalt shingles the streaks are usually a cyanobacterium called Gloeocapsa magma, which feeds on the limestone filler in the shingle and spreads on the wind, as the Asphalt Roofing Manufacturers Association explains. Tile, flat, and metal roofs grow algae and mildew of their own.
High pressure takes the protective surface off and can push water under the roof. We use a soft wash instead: low pressure, and a roof-safe cleaner that does the actual work.
High-pressure blasting compared with low-pressure soft wash on a roof| On your roof | High-pressure blasting | Our low-pressure soft wash |
|---|
| Shingles | Knocks off protective granules. | Granules stay in place. |

| Algae and mildew | Roots stay and streaks return sooner. | Cleaner kills growth at its base. |

| Water intrusion | Can force water under the roof surface. | Gentle flow that follows the way rain runs. |

Pinecrest roofs are mostly concrete tile and shingle on single-family homes, many sitting under a canopy that the village has protected for decades. Heat, humidity, and shade from mature trees grow algae and mildew faster on a shaded roof section than an open one. Tile work here stays comfortably below the roughly 1,200 psi limit tile care guides recommend, paired with a concrete-safe cleaner and footing kept to the spots where tiles overlap each other.
Pinecrest regulates tree work by ordinance, and while routine gutter and roof cleaning doesn't require a village permit, any trimming needed to reach a roofline safely should respect the same canopy rules the village applies to residents. Pinecrest is inside Miami-Dade County's High-Velocity Hurricane Zone, and roofing products installed here need a Miami-Dade Notice of Acceptance. We clean roofs. Repairs and re-roofing belong to a licensed roofer. Roofs closest to the heaviest canopy, particularly near Pinecrest Gardens, tend to need washing sooner than roofs on the village's more open edges.
Most roofs do well with a wash every two to three years. Shaded slopes and roofs under trees grow algae faster and may need it sooner. A damp, algae-covered roof also sheds more grit into the gutters below, which is one more reason we handle both in a single visit.
