A roof under West Palm Beach's historic oak canopy can grow algae faster than one in a newer, less-shaded yard, which is exactly the kind of buildup roof cleaning is built to clear.
Roof cleaning in West Palm Beach depends on which side of the historic-versus-newer line a house sits on. Close to a century of live oak canopy over neighborhoods like El Cid, Flamingo Park, and Old Northwood keeps shaded roof sections damp longer, and that shade speeds up algae growth well ahead of what a sun-exposed roof toward Grassy Waters Preserve develops.
Roof type here tends to follow construction era: the historic core often carries barrel tile dating back nearly a century, while newer construction runs more to asphalt shingle. Each needs a different touch. Tile can crack under direct high-pressure contact, and shingle granules wash away under a hard enough stream, so our roof cleaning uses a low-pressure soft wash on every roof type, not a blaster, so tile and shingle both come clean without stripping granules, cracking tile, or forcing water under the roofing material.
Grandview Heights sits just north of where the old Palm Beach Heights neighborhood was demolished in 1989 for CityPlace, and its bungalow roofs carry a shade pattern close to Old Northwood's. Prospect Park's deliberately planted, parkland-style canopy shades its rooflines evenly across the neighborhood rather than favoring one side of the street, which spreads algae growth evenly across every roof there instead of concentrating it on one block.
We have washed roofs in the shaded historic core and on sun-exposed newer streets in the same week and come away with very different before-and-after results, which is why we quote every roof cleaning job by the actual roof rather than by the neighborhood alone.
Roofs in West Palm Beach's older lakefront districts often carry barrel tile that has weathered close to a century of humid, rainforest-zone rainfall, while newer construction toward Grassy Waters runs more to asphalt shingle. Both grow algae faster under this city's wetter, less-seasonal climate than they would further north in Broward County.
