If you've driven down White City or through the Hutchinson Island waterfront in late summer, you've seen it: dark, ribbon-like stains marching down the north slope of otherwise fine roofs. That's not weathering. It's gloeocapsa magma — a living cyanobacteria — and it's eating the limestone filler in your shingles.
Fort Pierce is a near-perfect breeding ground. Coastal humidity keeps roofs damp long after the rain stops. Mature oak canopy over the older neighborhoods keeps rooflines shaded and slow to dry. And a lot of Fort Pierce homes still carry shingles installed 15–25 years ago that have never been cleaned.
Pressure washing an older Fort Pierce roof is one of the worst things you can do to it — it blasts granules into the gutters and voids most shingle warranties. Our shingle-safe soft wash uses professional cleaning solutions applied from ladders and the ground. The algae dies on contact, no one walks your brittle shingles, and the streaks are gone.
