The dark staining on Fort Wayne roofs is Gloeocapsa magma — a cyanobacteria that feeds on the limestone filler in asphalt shingles. It spreads spore by spore across your roof surface, digesting your shingles as it goes.
Left untreated, it shortens shingle life by 5–10 years. It also spreads to neighboring roofs via wind and birds — which is why entire neighborhoods develop the same streaking pattern.
Soft washing with professional biocide solution kills Gloeocapsa magma, moss, lichen, and algae at the root — not just bleaches them temporarily.
Every major asphalt shingle manufacturer — GAF, CertainTeed, Owens Corning — explicitly states that high-pressure washing voids the product warranty. The granule loss from a single pressure washing can age your roof by 3–5 years.
Sleek Siding FW never pressure washes roofs. Ever.
The Asphalt Roofing Manufacturers Association (ARMA) recommends a specific low-pressure method using sodium hypochlorite and surfactant solutions. That's exactly what we use — no guesswork, no shortcuts.
No — the opposite is true. Soft washing is the ARMA-approved cleaning method. Pressure washing DOES void most manufacturer warranties. We recommend getting this in writing from your roofer before letting anyone pressure wash your roof.
Most Fort Wayne roofs stay clean 2–5 years after a professional soft wash, depending on shade and biological pressure from surrounding trees. We can set up a recurring maintenance schedule.
Yes. We use biodegradable solutions and wet down all landscaping before starting. Runoff is neutralized and safe for grass, plants, and drainage.
