Those black streaks on Port St. Lucie roofs are gloeocapsa magma — a living algae eating your shingles. We kill it at the root with a shingle-safe soft wash, not high pressure.

Roof Washing in Port St. Lucie
Drive down Port St. Lucie Blvd, Gatlin Blvd, or any leafy street in Sandpiper Bay and you'll see the same thing: perfectly good roofs streaked with ugly black stains on the north-facing slope. Those aren't dirt. They aren't shadows. They're a living algae — gloeocapsa magma — feeding on the limestone filler in your shingles.
Port St. Lucie's climate is a gift to this stuff. Humid summers, dense shade through Tradition and Sandpiper Bay, and rooflines that stay damp for days after a storm. Left alone, the algae eats shingle granules — the #1 cause of premature roof failure.
High pressure will strip the streaks. It will also void your shingle warranty and blast granules into the gutters. Our shingle-safe soft wash uses professional cleaning solutions that kill the algae on contact, from the ground. No walking on wet shingles. No pressure damage. Streak-free rooflines that stay clean for years.
Local Conditions
Port St. Lucie sits in a humidity corridor between the Treasure Coast, the Helderberg Escarpment, and the Adirondack foothills. Combine that with mature tree canopies over most of the city's residential streets, and you've got the perfect breeding ground for roof algae.
Warm, damp summer air keeps shingles wet long after storms — ideal algae conditions.
Tradition, Sandpiper Bay, and Sandpiper Bay streets are shaded. Shade + damp = algae growth on north slopes within 3–5 years.
Port St. Lucie springs and falls are wet and slow-drying — extending the growing window well past summer.
Many Port St. Lucie homes have architectural shingles installed 10–20 years ago that are prime real estate for algae if never cleaned.
Why It Matters
Killing the algae stops granule loss — the leading cause of premature shingle failure in the Treasure Coast climate.
Shingle-safe soft wash. Low pressure and applied from ladders and the ground.
Bleach-only 'pressure wash' cleans just fade the streaks. Our treatment targets the algae itself, so results hold up far longer than a surface rinse.
A streak-free roofline is a huge win before selling — buyers see 'new roof' when it's really just clean.
Our Process
We check shingles, flashing, drip edge, and drainage before we quote — you get an honest read on your roof's condition.
Apply shingle-safe cleaning solution from the ground or ladder — never walking on wet, brittle shingles.
Low-pressure rinse, then flush and inspect your gutters and downspouts before we leave.
